Linux on HTC Hermes

[pof]

Hello,

Anyone interested in porting linux to HTC Hermes? The Samsung processor is currently supported by vanilla 2.6 kernel :D

I tried running GNU HaRET 2006070419 version, here's the output of some commands:


# telnet 192.168.1.23 9999

I don't think the Samsung SC32442A-400MHz processor is supported by this version of HaRET, but I found a page in russian (http://linux.sp.ru/) where there is a version of HaRET for s3c2442 processors available!! :)

Here is some interesting output of this haret version:

HaRET(3)# dump mmu mmu.txt


The MMU dump hungs the device :(

Samsung has also published manuals and datasheet of the processor, available here:

http://www.samsung.com/products/semiconductor/MobileSoC/ApplicationProcessor/ARM9Series/SC32442/SC32442.htm

More information and kernel patches for Samsung SC32442A procesor can be found here:

http://www.fluff.org/ben/linux/

So, we have a lot of work to do... any developers able to help?

[pof]

I've created a page on the wiki for the Hermes Linux port here:

http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux

[goestoeleven]

Forgive me for asking, but why would you want to put Linux on this device?

We've got enough issues getting support for the WM5 ROMs, don't you think?

If there's a good reason, I'd love to know what it is!

[Syphon Filter]

If there's a mountain to be climbed... :wink:

[goestoeleven]

That's what I figured... Good luck!

[vincefer]

Well, may be climbing that mountain is the main reason. But here you have another, in my opinion, interesting reason:

http://www.linuxdevices.com/articles/AT7937511405.html

[cr2]

The MMU dump hungs the device :(


What about running the "DUMP MMU" with gnuharet ? You can also try other commands
(POWERMON 10; NLED*)
They are ported from itsutils and should not depend on the CPU.

[pof]

Hey cr2! Sorry for the late reply but I didn't see your post before :(

With gnuharet, powermon 10 works, shows this:

HaRET(4)# powermon 10
2146258 1 70 % 3792 359 0 410 0 0 -1 -1 0 255 255 0 -1 -1 0 0 0 4
2147264 1 70 % 3792 359 0 410 0 0 -1 -1 0 255 255 0 -1 -1 0 0 0 4
[...]

Also nled* commands work, I can make the device vibrate with "nled on 1" and stop it with "nledoff 1", etc..

The MMU DUMP was ok with gnuharet, see attached file! :)

I also updated the wiki page (http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux) with some info about the Hermes hardware, as there are now pictures of the chipsets available, see this post:
http://forum.xda-developers.com/showthread.php?t=279151

[lkcl]

got one. busy with htc sable. start when i'm done or bored.

[pof]

Glad to see that lkcl and cr2 got an Hermes too :)

This sure means we'll see a linux kernel booting soon! :rolleyes:

[BRad Barnett]

It sure would be damned sweet to get rid of M$'s OS on this device! By the way, how is Qtopia and other Linux PDA "stuff" doing these days? The last time I tried it was back on my IPAQ in... 2001 I think.

[pof]

You have GPE (http://gpe.handhelds.org/) and Opie (http://opie.handhelds.org/) as the main graphic environment used in handheld devices those days.
It seems that soon a new environment called OpenMoko (http://www.openmoko.com/press/index.html) will be released under a free license too, this one is more phone-focused than the others.

[N2h]

pof
thanks for the post , im glad i came across it,
somethings been on my mind for the last few days, a mate at work is always on about Linux so it got me thinking, id like to give it a try on my TyTN
Iv got 2 questions for you,
first is there a newbie guid to running Linux on PDA's il have a look on wiki next im sure il find something. is there any that you guys can recommand which you have found helpfull.

2nd Now this is the question thats bugging me,,,,,
Can we run 2 OS on a PDA????
is this poss? to have a dual boot option when the PDA starts so we can select either Linux or WM05, both on there own will run on the device, how about installing both at the same time, and then being able to boot with one,

just some thoughts>?

I might start another thread on this just incase this thread isnt getting anymore traffic

well time to get back to work and start doing the job im actually getting paid to do

[pof]

first is there a newbie guid to running Linux on PDA's il have a look on wiki next im sure il find something. is there any that you guys can recommand which you have found helpfull.

Depends very much on which device you want to run linux, on the Hermes is not possible yet. But for the Universal or BlueAngel you have some guides here:

http://www.handhelds.org/moin/moin.cgi/Universal
http://www.handhelds.org/moin/moin.cgi/UniversalHowtoInstallLinux

You have WM5 on your flash, and Linux on the SD card. You start your pda with WinCE and then browse to storage card and run gnuharet.exe which will "destroy" WinCE and boot the Linux kernel and initrd found on FAT32 partition of SD card. Then from initrd, you mount the root filesystem on another partiton of the SD card... :)

[N2h]

pof thanks for the quick reply
il b ereading up on the guide links you have given,
also just to clarfy point 2

Today 02:05 PM
------------------------

by this means can we boot with WM and then run Linux from SD card once this is run would WM be completey wiped from device memory? so any data we had on the device for WM will be lost,
just so im explaing myself propley, i was wondering if you can keep both OS on the device and SD card boot from WM when you need that and when you want to use Linux boot with Linux but without losing you WM5 data etc.
same as some of the apple macs that can boot with windows and apple oc from the same machine and switch between the differnt OS's

thanks for the quick reply,

Iv got a collegue with universal I wonder if he will let me borrow his Universal??? lol

[pof]

You can boot linux from SD card and you don't loose any data on WM5 when you shutdown linux and go back to WM5.

[N2h]

pof thanks mate,

il be hopefully running Linux on my Tytn,
you never know,,,,,,,,,,, by the time i learn and update myself on linux it may running on our devices
all the best to anyone else also trying!!!

[elysion]

I would love to try and help you guys, but i haven't got much experience in these kind of stuff. Where should i start looking for more info on the project?

[pof]

The status of hermes linux port is always updated at this wiki page:
http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux

All development happens at #htc-linux in freenode irc server, but unfortunately as of now there's not a booting kernel yet for the Hermes, so you need some knowledge of low level programming to help at this stage.

[elysion]

i actually have studied low level programming with assembly and c, but i'm not that familiar with kernels :-/.

[samjam]

I have an Orange M3100 and kernel hacking experience under a different name.

I'll get the wiki-linked gnuharet and see if I can fail to boot linux blue-angel-style sometime today.

Can anyone share .config files being used as a current kernel start point?

Final question, is there anywhere debug output can go? If it helps I can write an encoder/decoder that uses hermes LEDs and a webcam on a PC to decode ascii text.

...

Sam

[cr2]

If it helps I can write an encoder/decoder that uses hermes LEDs and a webcam on a PC to decode ascii text.


Switching vibra "on" from a standalone haret payload is good enough:
http://wiki.xda-developers.com/index.php?pagename=HermesGPIO

It is not yet known how to control the LEDs.

[samjam]

So we're still trying to get haret to start to boot kernel, rather than adjust the booting kernel to boot properly?

[elysion]

I've done some testing with the haret and it seems that the keyboard is connected to the spi. Pressing a button on the keyboard also changes the states of gpe 0x1000 and 0x2000 values. Also i found out that when i use the touch screen it requests an iic interupt, but i'm really not sure what that means, because if i connect the pda to the charger it no more requests the interupt every time i touch the screen :-/. Any ideas why this happens?

Any suggestions what kind of research would be beneficial for the project at this stage?

one thing i found out also is that timer0 controls the pwm signal of the backlight... but that's a software thing, so not much benefit from knowing that as timers 0,1,2,3 at least support pwm. It's still somehow kinda neat to dim the backlight using haret :D.

[samjam]

About the iic interrupt; in your backlight settings do you have "turn off backlight if not used" disabled when not on battery power?

I guess so, and that the interrupt is to reset the backlight timeout.

Sam

[cr2]

I've done some testing with the haret and it seems that the keyboard is connected to the spi.

Can you determine the SPI clock speed ?

My first guess was that the "click" sound is sent to the speakers on a touch.
Can you trace the I2C datastream ?
On PXA there is an I2C monitor register at 0x40301688.


Any suggestions what kind of research would be beneficial for the project at this stage?

It is necessary to dump the CPU core settings like serial speeds, SPI speed, I2C ids and so on.

[samjam]

About the iic interrupt; in your backlight settings do you have "turn off backlight if not used" disabled when not on battery power?

I guess so, and that the interrupt is to reset the backlight timeout.

Sam

Or maybe it's to stop the auto-poweroff, which is also disabled by default when not running on battery.

I can help more, I've read the haret docs, but I still don't know how you used haret to get the results you did. I feel like a guy with his first lock-pick set.

Please could you post a step-by-step of how you used haret to find out about the interrupt? That should be enough to get me started.

I've reverse engineered memory maps for the old 2-line sharp pocket computers and such, I just need an introduction to effective use of these tools.

Thanks



Sam

[elysion]

Well, i just watched the interupt controllers source pending (srcpnd) register. Hope this is ok? The register is located at 0x4A000000 and i added the watch like this on the haret:
addwatch p2v(0x4A000000)

How can you use the haret while connected with an usb cable? I was able to figure out the ip address, but telnet cannot connect to port 9999 :-/.

[samjam]

What kernel do you have?
Are you using rndis or the old ipaq drivers? Have you got the pls tools working?

Hello there,

I have an Imate jasjam (aka tytn) and would love to see linux running on this device. I think the device has great potential and the M$ operating system lets it down.

I am sure I am not the only one waiting for someone to 'make it boot linux' to a useable level (eg phone, mp3, camera, bluetooth etc working). I would like to contribute but I am not sure how to do so.

Maybe we could set up a donations page?

Regards,

Kelly

[jasjamming]

it will ge nice to see a version of Ubuntu for the Tytn... Maybe the biollionaire who financially suports Ubunto and ships it for free could do something...

[renatostore]

Hi,
I'm near to receive a P3600 (Trinity) device and It seems to have the same hardware of Hermes. If so we can have only one thread to port linux on these devices. Can someone confirm my assunption?
Thanks

[cr2]

Is there an ascii registry dump somewhere ?
The serial port (s) speed settings do not make much sense to me ;-)

PS. Can confirm that the OHCI is used and running (also on Trinity),
so it seems very similar to the Universal's setup.

[pof]

PS. Can confirm that the OHCI is used and running
do u mean we can access it from USB already ??

[cr2]

do u mean we can access it from USB already ??
There is only 1 port (AFAIK) and it is used for UMTS data.
On pxa27x there are 3 host ports. 1 is used for UMTS, the 3 is unused.
We all hope that 2 can be convinced to access the external USB :)

[daveh85]

I guess it will now be easier to get this done now that the bootloader is unlocked :)

[pof]

No, linux is not flashed on NAND but booted from SD card.

[elfwine]

any update on porting linux in Hermes?

[rmorby]

Spotted this and my eyes nearly fell out

http://linuxdevices.com/news/NS9228125055.html

Linux on Hermes would be indeed very interesting. There is, however, clearly a big gap in the linux development community for smartphone. If only I'd stayed in IT.......

[elysion]

Wow! That project seems to have gotten quite far. Isn't it so that G500 has quite the same hardware in it as hermes?

btw. what's the status on the hermes kernel?

[vlahokel]

Is anybody still working on this project? If so what is the status?

Cant wait till my jasjam is booting linux :)

[john_van_v]

The phone industry has to change; the phone monopolies have been broken up, but the corporate minds are still missing the empathic facilities-- that is a genetic defect that allows corporations to operate without morality.

It is also possible that Linux is not necessarily the best OS for the project. Phones have no harddrives; Linux is a server system.

[Arktronic]

Phones have no harddrives; Linux is a server system.

There are RTOS versions of Linux, you know. One example is http://www.lynuxworks.com/

[cr2]

I dumped the pin config of the gpio ports, and got these results:


elysion,
i have put your data into wiki and added some other pins from my own
research. The I2S and CIF pin settings are still missing from the list.

[cr2]

The kernel boots on hermes, but there are some differences between the HERM100 and HERM200 behaviour.
Does anybody have a HERM300 to check ?

Hi cr2
I wish I could help. The only thing I have is a HERM300 aka MDA Vario II.
Unfortunately I have zero Linux knowledge. But anyway please could you explain the steps to boot the kernal and what we need to do this.
I think GnuHaret and a Telnet session are the simpliest things. Hope you show us M$ zombies the right way. :D

[cr2]

You need to put 3 files somewhere on wince in one directory:

zImage
haret.exe
default.txt

The first one is here http://handhelds.org/~koconnor/HTCHermes/zImage
The second one is here http://handhelds.org/~koconnor/haret
(take the latest version)
default.txt is a simple text file

set KERNEL zImage
bootlinux

Then start the haret.exe program, and press the Run button.

[scorpio16v]

Thanks for your reply.
Unfortunately booting stopps before the login prompt appears.:(

How did it stop ? Do you see the penguin ? Has the kernel crashed ?
Yes, TUX is allready there.:)
It ends with Code : e1520003 aa00036f e5963004 (e5931024)
Hope I read it correctly ?
And the cursor blinks, but no login prompt like in this picture:

Yes, it's a crash. But i have a better one for you :D
Get this executable and just run it
http://handhelds.org/~koconnor/HTCHermes/hack-haret.exe

It works for me, has and IP address of 192.168.0.206 (on usb)
and you can telnet there :)

The file doesn't exist on the server. :confused:

[cr2]

The file doesn't exist on the server. :confused:
Get it here http://jornada820.sf.net/files/haret
but be careful. It can destroy your hermes, kill a cat and so on.
just YMMV.

Or better use this one:
http://www.handhelds.org/~koconnor/HTCHermes/herm-linux-20070407.exe

[scorpio16v]

OK
It ends with:
/bin/sh: can't access tty; job control turned off
/ #
Telnet on 192.168.0.206 doesn't run. :(

edit:
the second file does the same crash

[kevin2]

OK
It ends with:
/bin/sh: can't access tty; job control turned off
/ #
Telnet on 192.168.0.206 doesn't run. :(

edit:

Use the file at:
http://www.handhelds.org/~koconnor/HTCHermes/herm-linux-20070407.exe

The procedure is this:
1 - Make sure usb is connected to hermes
2 - Run program above, and wait till it boots fully.
3 - unplug usb from hermes, and then plug it back in
4 - on host run: ifconfig usb0 192.168.0.200
5 - then run: telnet 192.168.0.206

Hope it works.

[cr2]

OK
It ends with:
/bin/sh: can't access tty; job control turned off
/ #
Telnet on 192.168.0.206 doesn't run. :(

You need to boot with the USB cable inserted, and
after seeing the command prompt on your LCD
pull it out and stick back in.
/sbin/lsusb should show

Bus 002 Device 101: ID 0525:a4a2 Netchip Technology, Inc. Linux-USB Ethernet/RNDIS Gadget


Then run

ifconfig usb0 192.168.0.1

telnet 192.168.0.206


edit:
the second file does the same crash

Ok. Do you telnet from windows ?

Yes,Is that the bug in my experiments ?:D

[cr2]

Yes,Is that the bug in my experiments ?:D

No, but it can explain the problems.
We used linux as you can guess :)

[scorpio16v]

After I went to the dark side (Linux) :) it semms to run.
btw My device shows:
/ # usb0: full speed config #1: 100mA, Ethernet Gadget, using CDC Ethernet
Is that host depended or a wrong driver ?

After a few minutes the Hermes screen went black. Is that normal ?

It is ok.

I have it too. We don't control the powersave functions on ATI chip,
so it's not surprising.

[vlahokel]

I know kevin2 is using a herm100 so you probably already know this, but..

My herm100 works as described by cr2 and kevin2.

Telnet via usb works. :) (on linux host, didnt try windows)

[Zgembo]

works here without problem on herm200... Same issue with powersave, screen becomes black... (after exactly 10 min here...)

[aybabtu]

Hi cr2, duno if you remember me, I tried to port linux to some smartphone before.
Granted I have limited knowledge on these low level stuff or even programming, but I think I can help testing at least.
Can you upload the booting kernel source to somewhere?
Just wanna have fun.

[pof]

Can you upload the booting kernel source to somewhere?

Download haret:
http://www.handhelds.org/~koconnor/HTCHermes/herm-linux-20070407.exe

Download zImage:
http://handhelds.org/~koconnor/HTCHermes/zImage

Put this on "default.txt":

set KERNEL zImage
bootlinux


Place everything in same folder, run haret and watch linux booting :)

You can connect via telnet to 192.168.0.206 trough usbnet.

[aybabtu]

Thanks pof,
but I already know how to download the compiled kernel and boot it,
maybe I wasn't clear and what I'm asking should be the patch
against the kernel, not the damn big source itself :)

[pof]

sorry I read you too fast :)

kernel is on handhelds.org CVS:
http://handhelds.org/cgi-bin/cvsweb.cgi/linux/kernel26/arch/arm/mach-s3c2410/htchermes/

You can download with:

$ export CVSROOT=:pserver:anoncvs@cvs.handhelds.org:/cvs
$ cvs login
$ cvs co linux


You'll need toolchain to crosscompile installed on your system, then "make htchermes_defconfig".

[aybabtu]

Got it, thanks pof.

[futureshock]

Hi, have just overfly the last few posts...

when i read right linux boots on hermes right now??

@pof and other gurus
I didn't understand the current development status. Once you get into the shell screen and login with telnet, what can you do? Only basic linux commands?

Beccatooooo
Comunque la mia voglia di veder girar linux sul tytn è sincera e spero di riuscir a contribuire al progetto...

It is never late to learn something :)

@Inphyy: Unfortunately if you are not a low level device programmer, there's not much you can do at this point, as linux is far from being usable now on hermes. A lot of drivers need to be developed / adapted and this requires some previous experience with kernel programming and reverse engineering as hardware specifications are sometimes not published. When we have an initrd that can be modified (now is embedded in the compressed zImage), then you can start playing with some init scripts, and help producing binary images of kernel and several GUI options available, and be beta tester and report bugs to developers.

Come into #htc-linux in freenode irc network if you want to follow the linux development progress on hermes and other htc devices; all the cool guys leading the development meet there, and lurking the channel is a very good source of wisdom if you are willing to learn.

[daveh85]

The last thing I get when it boots is:

"No filesystem could mount root, tried: ext2 vfat
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(1,0)"


Is this what everyone gets to?

thanks,
dave

[pof]

Are you using a standard haret to boot the kernel, or "herm-linux-20070407.exe" which contains embedded zImage and initrd?

[daveh85]

That would be why... I'm using one of the later builds... Sorry!

[gueee]

Hi there,

i'm joining as a linux-enthusiast and an experienced hobbyist in low level device programming as well as electronics-design.

Maybe my participation can get us a little further to see linux runnin on this kind of HTC device (tytn/HERM300 in my case).

[cr2]

i'm joining as a linux-enthusiast and an experienced hobbyist in low level device programming as well as electronics-design.


Get the kernel from CVS, compile it, boot and look for the bugs :)
Everything we know about the device is in the wiki.
The first obvious bug is linked to the NAND timing, which presumably
prevents the proper NAND chip identification:
http://pastebin.ca/508079

[brandenk]

Any updates? :confused:

[sarsaila]

please help me i try to make linux to boots on my hermes 100:(
i dont know how:(
it is any chance? to help me somebody ?
thank you very much!!!

[sarsaila]

:confused: :(

[lksey]

saesaila, you probably should read all about it once again(if u've read any info about that on wiki if not just go and read it)

if you've read it and there is nothing which can help you just list all the problems that you facing.

[cr2]

Any updates? :confused:

Yes, after extensive tracing of ATI SDIO and comparing with other devices
we can conclude that it's the same SDIO core as used in the ASIC3.
It means that a modified asic3-mmc (himalaya/blueangel/universal/sable) driver will work on hermes/trinity/athena.
The main roadblock for further development is removed :)

http://wiki.xda-developers.com/index.php?pagename=ATIWxxxx

[ss1271]

well....i think i was late to here....


i'm extremely interest in installing a Linux on Hermes, but donnot know how to start it...

anyone still working on it, please?

thanks a lot!!!!

[cr2]

It means that a modified asic3-mmc (himalaya/blueangel/universal/sable) driver will work on hermes/trinity/athena.

I've traced the operation of asic3-sdio and atiw-sdio.
They certainly share the same registers, but not the operation mode.
therefore we need a separate driver, and an update to 2.6.23 kernel

[ss1271]

if you mean...we cannot use Linux in Hermes yet...?:(

[iceberg303]

I know first we need a working kernel on the phone but has anyone thought about trying to get outside help?

From an HTC tech (not the company it's self)
From another embeded project?
From TrollTech?
Or from here: http://alp.access-company.com/

I have a cingular 8525 and with any of the decent WM roms I have issues with the back lighting on the keyboard not working most of the time so Id love to have a Linux install on it where I can more easily troubleshoot things in a more familiar environment.

A simple GUI like the Access, qtopia, opie or something similar would b ideal as well.

I have some inside information from Motorola. The US cell providers do everything in their power to prevent phones running linux from coming to the US. The Motorola Razr2 is a linux phone, but to bring it to the US Motorola had to write a new OS for the phone. This holds true with several of their other phones that were linux based outside the US.

The reason they do this is that if they control the OS they have greater control over what you can install and use on their without having to pay extra service fees. If the Razr2 were linux based it would be much easier to install free themes and ring tones.

So for those of us stuck in the US projects like this are very important. So what can I do to help? My social skills and debugging skills are better than my barely existent hardware hacking skills.

Things are not as easy as they were back in the Oki days.

[ANK08]

I'm agree, but I think there're 2 streets:

1. Free developing: this mean IMHO to ask help to an available to free (= accessible and modifiable, not necessary "gratis" :) ) code developer;
2. Close solution: to ask a company o a freelance developer help that can will propose to buy or download for free a close kernel and/or GUI.

Who's intersted to what? :)

However I'm agree to find the solution, otherwise I'm thinking to sell my Tytn :( : Win is too inefficient and slow.

[__a]

Hi!
I have a Tytn device and i'm a linux novice. how can i help develop this thing?!


Best regards

Albert

EDIT: Got the latest files up and running on my device.. awsome :D

[__a]

Since there was no straight-forward howto on getting hermes-linux up and running (and because it took me a while to figure out) i decided to write one myself! =) ..please feel free to use it as you please and also let me know if i wrote something wrong and I'll fix it!


Linux on TyTn

1. Get usbnet for your computer. Make sure to set up usbnet to have the static ip address 192.168.0.1.
linux: just setup the ip (ifconfig usb0 192.168.0.1)
osx: http://www.dsitri.de/wiki.php?page=AJZaurusUSB
win: http://docwiki.gumstix.org/Windows_XP_usbnet

problems? http://docwiki.gumstix.org/Setting_up_USBnet

2. Add an EXT3 partion to your device's memory card. It is important that you also keep a FAT-partion for Windows Mobile.

3. Go to http://handhelds.org/~koconnor/HTCHermes/

4. Get the latest herm-linux- file (currently herm-linux-20070930.exe)


EDIT: Steps 5-7 are not needed to use herm-linux-20070930.exe
5. Get the latest zImage file (currently zImage-20070709)

6. Create a file called default.txt:


set KERNEL zImage
bootlinux



7. Put these three files in a folder on your FAT-partion on the device's memory card (NOT the EXT3 partion!!!)
/EDIT

8. With usb-cable plugged in, run herm-linux-XXXXXXXXXX.exe. Linux will boot to somethink similar to this:


BusyBox v1.1.0 (2006.02.24-18:59+0000) Built-in shell (aSh)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
/ w



9. Unplugg the usb-cable and plug it back in again. Device will output something like:


usb0: full speed config w1: 100 mA, Ethernet Gadget, usi
ng CDC Ethernet



10. On your computer, telnet to 192.168.0.206:


$ telnet 192.168.0.206
Trying 192.168.0.206...
Connected to 192.168.0.206.
Escape character is '^]'.



BusyBox v1.1.0 (2006.02.24-18:59+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.



DONE!

[scorpio16v]

just for curiosity :)
what is the difference between your way and the way to boot with haret ?
(described in post #49)

[__a]

It is the same, but like I said there is no howto, so i wrote down how to get everything up and running step by step ;)

I know it will probably not help the development on the current stage of low-level programming, since all this must be rather obvious if your in that deep. I just thought that since I managed to figure out how to complete the install I might as well try to contribute the best I can with this knowledge if someone else like me wants to try it out!

Hi! I have a Magician and a Hermes, on the magician linux works relatively fine, but now i would really like to use my hermes with it too.
I have been using Linux on my desktop long time ago, and i have some knowledge about how does it works and some programming.
My question is, how to work on the kernel for the pda? where is the source code for it, how to compile it? I really want to work on it and at least make it work the sd reader and/or keyboard. I dont think that'll be hard to make the keyboard to work.
Greetings!

Hello.

How far are the development of linux to hermes? I am very exited if this is possible. But is the newest kernel to hermes from 2007? I got it running as well, but haven't there been any further development?

[__a]

Hi tball!
if you look at the wiki-page you can see how far the development has come:
http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux

so far the list includes:
* HermesMemoryMap
* GPIO
* Hermes hardware
* Hermes video
* Hermes CPLD
* Hermes keyboard keycodes

Newest build is "haret-20080304.exe" as far as i can see on
http://handhelds.org/~koconnor/haret/

[jontxudino]

hmm! yes, you are right! i booted, but no keyboard supprt... :S
im i doing something wrong?? mm....

[cr2]

hmm! yes, you are right! i booted, but no keyboard supprt... :S

you need to compile the 2.6.24 version (i think) from linuxtogo git repository.

[jontxudino]

mmm... that make sense...!
ill try tomorrow, im going to sleep. is 3AM here already xD
thanks!

[cr2]

Bad eraseblock 1 at 0x???????? (so fast i cant read it)

The NAND layout makes S3C-NAND driver unhappy.


No filesystem could mount root, tried: ext2 vfat
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)

The SD driver is unfinished, so you are forced to use ramdisk or mount root over nfs.

[jontxudino]

Actually, the problem was that i was using the regular haret application, which as far as i know it have the initrd binary...
correct me if im wrong please...
All of this staff ill go updating on the wiki tomorrow.
To have the keyboard working is a nice step, for me at least...

help me to install driver :(

[jontxudino]

help to install what driver? if you mean the usb driver for ethernet depending on the distro you use on your host pc it will already be installed. im not sure right now, but I bet that on my ubuntu was already installed the last time I tried. today ill update the wiki.
bye!

It says EXT3 hmm, I think we can put getnoo stage4 there will gui work then?

[jontxudino]

No. It doesnt have nothing to do with the filesystem
you need controllers for making the hermes' hardware know how to act in every moment.

[jontxudino]

Hi again... xD
im trying to compile the kernel but no way...
I start in my host computer running Ubuntu with this:
make htchermes_defconfig
im not sure if that's right. What am i supposed to do later?
Thank you!

[__a]

what kernel are you trying to compile?

[jontxudino]

the lastest from linuxtogo git repository

[ixar]

I am interested as well in getting linux working on my Hermes, I will give it a try to see if I can do anything helpful to port it.

[ixar]

Ok now I have everything set up.
I have been able to recompile linux kernel from cvs.hh.org, rebuild a initrd with a busybox, rebuild a bundle with haret.

I read somwhere that the keyboard was supported, but it does not look to work on my kernel build. Maybe I will try to fix that first.
(edit: it seems that the linuxtogo git repository has the latest changes, I will try it tonight).

Then I will have a look at the ati driver, since vsfb is blocking a standalone boot (ie without wince).

If you have any pointer, doc, suggestion do not hesitate.

[__a]

OK, just checking!


If you have any pointer, doc, suggestion do not hesitate.

i suppose you've already tried the wiki (http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux) ? have you checked the irc-channel (including logs) too? i think there is a lot of knowledge on irc that hasnt been documented here or on the wiki.

[cr2]

Then I will have a look at the ati driver, since vsfb is blocking a standalone boot (ie without wince).


I've done a lot of research into the ATI init, and will try to document it in the comimg two
weeks. The most difficult part is the clock setup.

For me it works, I used the git linuxtogo reposistory branch "work".

I have some bugs on the keyboard management, but I am working on it. Maybe it does not come directly from the keyboard driver itself.

To add your program you can add it in the init ramdisk or you could even try to put it on the SD card and mount the FAT, but I didn't try it myself.

For the moment I focus on the kernel itself.

Sounds great ixar! Could you tell us what you have done, and update the wiki-page maybe? That way more people might want to/be able to join the project.. as of now the wiki makes it look like there is almost nothing going on :(

I will put a step by step procedure for those who wants to try it themself. In order to have a fully working dev environment. It took me some time to figure out how everything works (ie Haret is used as a bootloader and contains an embedded kernel image along with the initrd).

I also intend to release my work for testing purposes if anyone is interested.

I will do it by the end of the week. But you know how it works, it is not easy to keep a schedule as I do it during my free time ;)

For the progresses, it may even take me longer as I need first to understand the hardware itself and how things works.

[hoatienii]

i can't run Linux on my Hermes, hope you have many change, can run Linux on hermes

[ixar]

For those who wants to try to compile the bleeding edge kernel, here are some quicksteps for developers:
1- Install an arm toolchain (or build it yourself)
2- Install cegcc (necessary to build haret from source)
3- Get the source code from:
* Haret: git.linuxtogo.org
* Linux kernel 2.6: git.linuxtogo.org (branch work for latest changes)
* Busybox: http://www.busybox.net
4- Compile Haret with cegcc
5- Compile linux 2.6: make defconfig_htchermes; make CROSS_COMPILE=arm-elf-
6- Compile Busybox: configure ... make CROSS_COMPILE=arm-elf-
7- Make an initrd using busybox as basis
8- Use Haret to make a bootloader "linload": See target linload from Haret root Makefile
9- Copy haret/out/linload.exe to your hermes, and run !

The previous instructions are a not very detailled, but if you have some experience in embedded system it should be enough for you. I wrote it down so that others find the information they lack to get started.

You do not need to understand all this to be able to help porting linux to the hermes.
I am currently scripting all those tasks to ease the process of creating a development environment. This way most people should be able to try themselves and help us porting/testing ;)

Since there was no straight-forward howto on getting hermes-linux up and running (and because it took me a while to figure out) i decided to write one myself! =) ..please feel free to use it as you please and also let me know if i wrote something wrong and I'll fix it!


Linux on TyTn

1. Get usbnet for your computer. Make sure to set up usbnet to have the static ip address 192.168.0.1.
linux: just setup the ip (ifconfig usb0 192.168.0.1)
osx: http://www.dsitri.de/wiki.php?page=AJZaurusUSB
win: http://docwiki.gumstix.org/Windows_XP_usbnet

problems? http://docwiki.gumstix.org/Setting_up_USBnet

2. Add an EXT3 partion to your device's memory card. It is important that you also keep a FAT-partion for Windows Mobile.

3. Go to http://handhelds.org/~koconnor/HTCHermes/

4. Get the latest herm-linux- file (currently herm-linux-20070930.exe)

5. Get the latest zImage file (currently zImage-20070709)

6. Create a file called default.txt:


set KERNEL zImage
bootlinux



7. Put these three files in a folder on your FAT-partion on the device's memory card (NOT the EXT3 partion!!!)

8. With usb-cable plugged in, run herm-linux-XXXXXXXXXX.exe. Linux will boot to somethink similar to this:


BusyBox v1.1.0 (2006.02.24-18:59+0000) Built-in shell (aSh)
Enter 'help' for a list of built-in commands.

/bin/sh: can't access tty; job control turned off
/ w



9. Unplugg the usb-cable and plug it back in again. Device will output something like:


usb0: full speed config w1: 100 mA, Ethernet Gadget, usi
ng CDC Ethernet



10. On your computer, telnet to 192.168.0.206:


$ telnet 192.168.0.206
Trying 192.168.0.206...
Connected to 192.168.0.206.
Escape character is '^]'.



BusyBox v1.1.0 (2006.02.24-18:59+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands.



DONE!

That is wrong!!!!!!.
herm-linux-20070930.exe file include linux kernel image, so it will not need zImage file.
So I think: herm-linux-20070930.exe = haret.exe + default.txt + zImage ; and it will auto run.
Am I right??

Hello,
I'm wondering if we can combine this thread with the Google Android thread,

Because other people here on XDA already managed to get android working on the Kaiser/Touch...

Maybe we can use the experience from here with that?

Here are the links to Android on the Kaiser en the Touch(Vogue)

and

[ixar]

I am also interested in Android as it might lead to a usable handheld platform. However I read somwhere it had minimal requirements regarding the CPU that is not matched by the CPU in the Hermes. Please correct me if I am wrong, I didn't find back this information.

Regarding linux itself on the Hermes I am still playing with it. I have almost finished scripting the build tools to allow anyone to help porting linux on the Hermes easily.

I have had a look at existing build platform (bitbake...), but I need more time to understand how everything integrates together. My need currently is something that works from scratch: build toolchain, kernel, initrd, packages. This is what I am gonna try to provide.

Cheers

[TripleQ]

Great :)

Anyway, the Kaiser and the Hermes has the same amount of cpu...both have 400mhz

Hello anybody, I have a question.
Now, I can use ramdisk to boot linux in my Hermes. And now i want to mount root file in Store Card and build keypad driver. How to start do it, and have any instruction for me????

[bje2525]

ok first off i know i should not try this since i am newbie.....but would like to try linux on my hermes....can some one email or send me a how to to port it to it....i know some about linux since i use it on my pc....any help please.....

[joeavery2]

I was on Openmoko's web site and it seems the neo freerunner will be using the same processor. I know this was a issue early on but I thought I would throw it out there, they might be able to help, or thier kernal may be usable. I realize though that it appears the current issue is getting the gpio's right, and getting the rest of the chipset working right.

[shamus]

I hope it helps in linux development, recent JTAG points discovery might help you in low level programing, testing and gpio finding.

I have loaded latest haret.exe, compiled new zImage as described in post:

http://forum.xda-developers.com/showpost.php?p=2259079&postcount=3

For branch I used "work" and there could be found "htchermes_defconfig" so I used it. Result is that I have some warning about keyboard not supported in hermes and 4 functions have something buggy, but still I can get fresh zImage. zImage is about 1,08M and when I try to run it on Haret it says zImage could not be loaded because it is too big? So how to get forward from this point?

Hi there,

maybe some additional things should be pointed out, if something like android should ever run on hermes.

Anyone out there who could post the settings for the EGPIO registers at physical address 0x8000000 ????

Very interesting attempt, but which android image would you like to run??
Is it taken from kaiser?
The kaiser image uses ARM V5 compiled binaries. Won't work on hermes i suppose.

Maybe give it a try :p
Anyway if the bootparams are set correctly the kernel should jump into initrd.
Give some more details about your startup script!

Does anyone know if there's EGPIO support in latest linux kernel for hermes??

By the way...
Is the handhelds.org kernel more or less up to date :confused:
At least it started on my device.

Which kernel do you use out there?

scholbert

[sniveri]

I compiled kernel from git clone git.linuxtogo.org/home/groups/mobile-linux/kernel.git. And for some reason Haret must be 0.5.2 not 0.5.1 if you want to boot with hermes.

Working initrd with busybox can be found from http://www.pierrox.net/G500/20080203/initrd.img.gz

Yep, I got it work with initrd image that was build for EtenG500 device. But I can not do anything with it because I have broken keyboard on hermes and I can not create usb-connection to hermes from my linux desktop.

So you got it to work? What steps did you take? Go slow I'm a fresh Linux convert, but I learn fast ;)

[sniveri]

Those steps are told in this thread several times:

-Compile latest HaRET
-Compile latest zImage
-Create root filesystem or use existing one (initrd file)
-Create default.txt that contains pointers to zImage and initrd
-Start HaRET and play with it

[victor.hugorr]

can you send the right files to do it?
because a runned the haret0.5.2 found here:http://www.pierrox.net/G500/20080203/haret.exe

and this zImage: http://www.pierrox.net/G500/20080203/zImage

And it stop on the message:

Sorry, i don't know too much about this!

[sniveri]

http://forum.xda-developers.com/showthread.php?t=404145#10

Try those and modify your default.txt looking something like:


set kernel zImage
set initrd initrd.img.gz
set cmdline "root=/dev/ram0"
boot

[scholbert]

Hi victor.hugorr,

the linux kernel is a very specific part of software and has to match to the hardware.

...and this zImage: http://www.pierrox.net/G500/20080203/zImage


This kernel will never work properly on hermes because it is set up for an Eten G500. :p

Please use sniveri's kernel or compile your own, using a hermes configuration.
Of course the default.txt should contain something useful too :D

were or how can i dl the kernel....that u say to use the one from sniveri

latest link for zImage to other post or compile new one. Kernel is in zImage when using HaRET.

Emdebian would be nice to get running on Hermes. At least it should support armv4. Android is at this moment not possible as many of you have told. So does anyone have experienses creating rootfilesystem emdebian-tools?

I tried and did it in a hurry and got my Ubuntu box messed up. After installing emdebian-tools it automatically adds debian sources to your apt-sources list and I did apt-get update&upgrade :D Have to try to install also Debian to this machine. Funny how they have made installation trough a netsite:

http://goodbye-microsoft.com/ :D

[TripleQ]

which apt-source you used to get that packages?

I have debian Etch, and it cant find the emdebian-tools package:confused:

[sniveri]

I had it on ubuntu allready http://packages.ubuntu.com/hardy/emdebian-tools But after the install there was more sources added and then things got messed up.

[sniveri]

which apt-source you used to get that packages?

I have debian Etch, and it cant find the emdebian-tools package:confused:

I finally got debian configured to my desktop. You can find from emdebian-tools pages that it is still unstable and because of that it is found from debian sid. So I had to remove all other sources and use sid only, after that you can find latest emdebian-tools and emdebian-rootfs.

[TripleQ]

aahw ok :)
That make some something clear!

I am at work right now, but tonight i can play with it!
Going todo a fresh unstable debian install then. (vmware)

[sniveri]

hmm.. I readed from emdebian guide that it supports armv4t and armv5t but not armv4? so what is hermes, armv4 or armv4t? Maybe openmoko would work, that should be for armv4.

[scholbert]

Hi,

hmm.. I readed from emdebian guide that it supports armv4t and armv5t but not armv4? so what is hermes, armv4 or armv4t? Maybe openmoko would work, that should be for armv4.

To clear this up have a look at:
http://en.wikipedia.org/wiki/ARM_architecture

HTC Hermes uses S3C2442 with embedded memory (Mobile SDRAM / NAND Flash).
This MPU uses ARM920T core. The processor family is ARM9TDMI.
The instruction set is ARMv4T.

If you compile some source code you should tell your compiler which instruction set to use. ARMv4 is the base, the "t" stands for thumb mode.

This means the processor core is also capable to handle 16Bit instructions , if started in thumb mode.

On Hermes 32Bit ARM instructions are used.

Created new emdebian filesystem using emsandbox. Running this filesystem image in haret displays following text


RAMDISK: Compressed image found at block 0
RAMDISK: incomplete write (-28 != 32768) 4194304


And after that follows kernel panic because it is unable to mount rootfilesystem. Any ideas what this means?

No and no, not really. All you can do is boot from within Windows Mobile through HaRET (http://handhelds.org/moin/moin.cgi/HaRET)

Android does not work with hermes.

[victor.hugorr]

sniveri, so there is some linux version wich works?

[scholbert]

Hi,

please read this thread again, to get an idea of what has been done so far.
Linux on hermes is in a very experimental state.
Forget about android, it's too heavy to port it to hermes hardware.

Although the kernel had been further improved in the last few month.
Someone could check what exactly is working and we could post an updated list :D.

There are some good starting points, for a rootfs with some kind of gui.
Especially in the last few weeks there had been a lot of useful hints.
Have a look at openmoko.org, very similar hardware...
At the moment there's a working initrd with login over usb network emulation.

Regards,

scholbert

Gosh, this is wonderful flame-war material :D

OnT: I'm not fully down with exactly what is missing and what is working with the kernel right now, so I started a to-do-list on the wiki page (http://wiki.xda-developers.com/index.php?pagename=Hermes_Linux) with the things that came to my mind. Of course most of them are pretty far away, but if you people would put in the more short-term problems, maybe people like me eventually find something that we can actually start learning and maybe actually contribute something instead of just trolling around in this thread :D

hmm..

Does the SDcard work properly allready?

I`m not sure but somehow I have feeling that keyboard was working with some kernel but not in this newest kernel at git.linuxtogo.org, or maybe I had a dream :D

No, it was no dream, sniveri :rolleyes:
The keyboard is partly working, some special characters are missing though.
Perhaps the keymap has to be updated. Don't know which one is used at the moment.

Anyway i used the latest sources from git.linuxtogo.org, so this maybe a good starting point!

There was some discussion at #htc-linux that hermes is waiting for sd-card support, after that they can continue working with ati-chip, wifi bluetooth etc..

[scholbert]

Hi,

...hermes is waiting for sd-card support, ...
I just did some research the last days, what would be the best starting point to make sdcard work.
It seems that the best thing to try, is to integrate the openmoko patches for sdcard support into mobile linux git tree.

You may download a kernel snapshot from here:
http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=shortlog;h=refs/heads/work

Openmoko patches for this kernel (2.6.23) could be found right here:
http://svn.openmoko.org/branches/src/target/kernel/2.6.23.x/patches

You also need to add a few lines to htchermes.c.
I may post a patch for that, if someones interested :rolleyes:

Though this is not the latest kernel, there seem to be the best results.
The zImage is compiling fine and it is running on hermes.

Unfortunately a useful initrd is still missing and due to lack of time some further tests haven't been done yet.
Maybe there'll be something useful in the next weeks.

Of course i like to play around with hermes and just do this for fun :D ,personally i think linux development for the hermes will get stuck at some point.
Obviously there are much more interesting and powerful devices on market already.
At least the kaiser will do it to much better support concerning linux stuff i suppose...
...and there's freerunner :p

Cheers,

integrate the openmoko patches for sdcard support into mobile linux git tree.

the moko-patched s3c-sdi driver will provide SDIO support for your wifi init.
The SD card is connected to the ATI chip, and is using ATI SD controller.
It's all documented in xda-dev wiki:
http://wiki.xda-developers.com/index.php?pagename=ATIWxxxx

http://wiki.xda-developers.com/index...ename=ATIWxxxx
Can't believe it... is it really true?

In this case we will never get sdcard working with the openmoko stuff and i think it will be very hard to get a working driver.

I really thought the engineers at HTC used the SD-interface of the Samsung chip for this function, because there's a DLL named sdhc_sc2410.dll in windows folder. So sorry for confusion ;)

There's not much information about the ATI chip (except for the wiki of course). Damned!

Anyway, thanks for the information!

This is not possible.
To start linux on hermes an application named haret is used.
It is a wince application that may also used to debug the unit.

So no chance to boot linux without wince up and running :p
As long as the bootloader screen shows up you may be able to fix your device using other methods.

Search the forum or use the wiki for instructions, how to do it.

I have read somewhere that linux has been flashed to ipaq memory but I could be wrong. But in hermes case flashing is not wise(or it could be impossible) as there is no working linux drivers etc for it.

Did you get anything out of it?

[scholbert]

Hi,

again i pulled out the mobile-linux kernel 2.6.23 from linuxtogo and added some missing files to check the function of the experimental ati driver on hermes (took it from athena platform inside hh.org kernel).

Now I want to porting for my device, but I dont know how to start. Can any people have docs or instruction for me?

Obviously there's no simple how-to, you'll have to read this thread and extract the useful things to start development.
At least a lot of information may be found :p.

In my opinion, the mobile-linux kernel is a good starting point, because there are already some new features implemented (e.g. keyboard driver).
I suggest to use a linux environment and focus on kernel development for now.
Any newer GCC compiler for ARM may be used, to get at least a starting kernel image. To use haret as bootloader is mandatory.

Did you get anything out of it?
Unfortunately there are some things missing to make it work, but maybe a solution could be found. The problem is the interrupt source for sdcard access. Not sure how it should be implemented...

I'm quite unsure if the sdcard part on hermes uses true polling mode or a dedicated interrrupt to trigger the access.
The ati_w driver needs some interrupt, so i decided to use the sd detection pin for this purpose. With this kernel there are some driver messages when a card is inserted but i got no answer from the card itself.
I PM'ed CR2 if he knows some details about this. Perhaps he might help...

At the moment my time is very limited, but i think i'll try to get some more efforts on this the next weeks :o

Maybe i am wrong but let me point it out like that:
The Hermes linux kernel port has been left in an experimental state in hh.org kernel. So i'd consider this as the reference or base repository.

Some further development has been made in the mobile linux rep. This kernel has some updated driver code and additional features.
http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=tree;hb=work

I'd suggest this rep as a starting point for further development, because it's a newer version (2.6.23) compared to the hh.org kernel tree.
You may use the hh.org defconfig for hermes using make oldconfig...

At the moment i started porting all hermes stuff to the latest stable kernel tree from openmoko. There are many improvements in this kernel and there's a lot of active development (mainly for GTA02 platform of course).
The GTA02 is very similar to the hermes platform and i hope to get some new ideas to adapt some more drivers to work for hermes.

Hopefully i will get a booting kernel soon.
At least i'd like to reach the state of the mobile linux kernel for hermes.
There are still some missing files, new structures to handle and other stuff to make it work.

Hope this helps....

Cheers,

scholbert

Do we have some todo list for the development?

Cheers,
Mihailo

In the major points, the wiki is up to date...
Some additional information could be found in this thread, as you might recognized already :rolleyes:

Someone had put a todo list in the wiki, some time ago...
These parts are (partly) working:
Basic Platform Support done!
USB Device Driver done!
NAND Flash Driver (needs some fixes though)
EGPIO done!
Keyboard (not all keys are working)
Basic Framebuffer (vsfb is working if booting from WM)
Touchscreen (not sure about this, and never tested this)
Keypad/Buttons (maybe some minor fixes are required)

and these drivers are still missing:
SD-Card (very urgently needed)
Real Framebuffer for ATI GPU (vsfb is used instead)
Bluetooth
Wifi
GSM Chipset Support (nothing has been done yet)
Power Management
Audio
Camera

I think the bootloader could be considered as optional task.
It should be possible to port u-boot as a bootloader in the end (but that's far away i suppose...)

Anyway please add apost if i forgot something....
Just wrote it down from memory ;)

hi scholbert,
I got the code from http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=tree;h=refs/heads/master;hb=master as you suggested. How do I build it for hermes specificaly? hh.org has htchermes_defconfig but it cannot be used as is. After unsucessful attempts to make it work I finally tested if I can build anything and I was able to build using s3c2410_defconfig.
This definitely means I can build but I need proper hermes config file I guess. Another thing: I don't see hermes specific stuff (I haven't been looking much though) in the code, and on the hh.org version there are folders like: kernel26/arch/arm/mach-s3c2442/htchermes this is a bit puzzling for me.
I hoped to get this running tonight but since I'm learning along the way end of the week seems more realistic.

Thanks,
Mihailo

[scholbert]

Oooooops....:o

I put the wrong link in my posting, im very sorry for that.
Have a look here:
http://git.linuxtogo.org/?p=groups/mobile-linux/kernel.git;a=tree;hb=work

It's the work tree of this rep.
Have a look inside first and you'll see there's kernel26/arch/arm/mach-s3c2442/htchermes

I very sorry for this missleading info :rolleyes:

This definitely means I can build but I need proper hermes config file I guess


Take the handhelds org defconfig first and use make oldconfig or see attachment :p

EDIT: I just decided to put also my experimental stuff in here!
The file experimental.zip contains a patchset to add the atiw experimental driver and an addon from openmoko rep to support the internal SD interface of S3C2442. This interface maybe communicate to the wlan chipset someday!
You may remember that the wifi chipset is attached using the SDIO interface

Don't expect too much, because these drivers do not work properly.
Anyway this may be used as a base for further development.

Oh damn it :)
At least I learned something.
I'm not expecting too much, I just want to build my own kernel et al. and run it on my Hermes successfully by the end of the week. After that I'll start messing around with SD card (or at least try to ;) )

Anyway I'll try working this out tonight and see if I make any progress.

Thanks!

Hi again,

i just thought about better basic graphic support (apart from vfsb).
Again i took a short look on the existing drivers in the kernel source mentioned above.

Did anyone ever tried to use the implemented w100fb driver for hermes?
I realized that most of the dedicated registers of atiw228x could be found.
So the framework looks identical.
At least this driver should work for most Imageon products i suppose.

Any ideas, experience, suggestions, patches ??????
Anyone, Anywhere.......

[mangiaculo]

I've found a thread with work done to patch the sd drivers for hermes here (http://www.handhelds.org/hypermail/kernel-discuss/current/3902.html). There are a few patches linked in there which I've dl'd. I'm not sure if these patches have been applied to the current drivers in the git kernel, but maybe they could be applied, or used as a starting point?

The SD-Card slot is attached to the ATI chipset inside hermes.
That's why it isn't solved yet :o

because this gives you a slight idea about the state of art ;)

Thanks again, I'll try to get a better understanding of this. I just pulled down your images and the source from linuxtogo.

[scholbert]

Nice,

if you need some help, tell me!
You may need an arm cross-toolchain on your linux host to compile the kernel.
Have a look here:
http://downloads.openmoko.org/toolchains/

EDIT: I personally use this older one, because i had problems with the newer ones (some missing libs on my system).
http://downloads.openmoko.org/toolchains/openmoko-i686-20080521-armv4t-linux-gnueabi-toolchain-openmoko.tar.bz2

Please follow the instructions on the openmoko wiki on how to install...

Good luck!!

[mlalevic]

hey Scholbert,
We should probably setup some wiki entry for this. That old post on how to build your own kernel is for most of the part useless unless you have lots of experience with building Linux kernel in the first place. I know the pain, it took me almost 2 weeks to get to the point 0 - make everything build, and make it work whatever was done so far.

There should be stuff like where to find your toolchain, how to make busybox, how to prepare your initramfs/initrd etc.

I'm using Code Sourcery's tool chain (I have to admit, I'm using it since it was easiest to setup).

http://www.codesourcery.com/gnu_toolchains/arm/portal/subscription?@template=lite

The gnu-linux one. It worked fine for me. I managed to build and make kernel boot from first, but then I got stuck on making my own initramfs (well I tried making initrd too). Lack of resources (it's hard to find useful ones) and knowledge at the beginning and a week later I figured out that I was missing bl**dy switch in the gcc compiler so busybox was hanging on start because it was compiled for the wrong arm processor. Good thing is I got into writing debug output in kernel so at least I know where the things are now :)
So I know the pain which people might have, and that's why I'm suggesting we add a wiki entry explaining where the things are and how to setup everything. Another major PITA is that it seems to me noone is maintaining the code. I saw there are changes in the SDI drivers in the latest kernel, but I just have hard time even recognizing which code should we be working on (I'm using working version from git, and will continue there). So list of versions/patches/code repositories we should be using would be very helpful.
Anyway, I don't know how, or even if I can add entry myself, and there is probably much more that you could contribute, so please let me know what you think about the idea.

And now the latest status:
Keyboard is not working, at least it is not working immediately. For me, sometimes it did not work at all, sometimes started working after a minute or two ... there are lots of interrupts happening and no keys captured, I think that's just not right. There has to be some initialization issue. Is it working alright for you?

Haret is not working on my hermes (with haret console, it is booting linux alright), what Windows Mobile version do you have? I have 6.1 I think, it seems it can't open the tcp connection, I got very frustrated after a while, and dropped investigating further, any ideas?

I've started investigating SD card interface with ATI gimme one more week and I'll probably have some more useful information.

Anyway, lack of knowledge and time is driving me nuts, but I won't let that stop me ;)

Unfortunately i never added some parts to the wiki, should be possible anyway.

Had some problems with the keyboard either, but it worked most the time.
Could also be some sort of timing issue....
But this is no main issue at the moment, i think.

Haret is not working on my hermes (with haret console, it is booting linux alright), what Windows Mobile version do you have? I have 6.1 I think, it seems it can't open the tcp connection, I got very frustrated after a while, and dropped investigating further, any ideas?
I will post my version of haret and a startup script.
Haret seems to have some problems with some versions of WM6.1.
I once stumbled over some thread about this issue... but don't remember exactly.
Anyway, never had a problem with my version and i also flashed on of the latest ROMs of CRC on my device.

I've started investigating SD card interface with ATI gimme one more week and I'll probably have some more useful information.
No problem! As you might found out, i prepared a patch with the latest attempt to implement the SD stuff. Not working though...
It's in the experimental archive.

My time is very limited at the moment (like always), so let's see how far we would get with all that stuff :o.

Thanks a lot for this comprehensive post!!!

Hi,

please have a look at one of my previous posts in this thread,
grab experimental.zip, extract it ...
get the the file "patchset-2.6.23-hh20-ssc.patch"
and apply it to the mobile-linux-2.6.23-hh20.

You may use the config from this package too and compile the kernel :D

Hi there!

Mihailo reported some problems using haret on a WM6.1 OS.
So perhaps this helps...

I will post my version of haret and a startup script.

This version is not the most up to date, but it works very well on my hermes devices with WM6.1.
Check it out....

Could have several reasons:

You're trying to run a kernel compiled for hermes on trinity device.
Although the devices are similar, the setup and usage or some hardware parts may differ.

You're using a initrd from vogue. I don't know much about this architecture, but there could be some startup scripts that do not fit for the trinity or the hermes. Maybe a driver is missing or similar.

I'm sorry but there are so many possibilities why you get no login console...
It's only guessing :rolleyes:

Good luck,

scholbert

[tuksedra]

thanks scholbert, mm.. i have to mess with the kernel.. how to make initrd...

[utak3r]

If anyone's interested... here you can download (http://utak3r.buzzdev.org/2009/02/26/samsung-s3c2440-manual/) a full SC32442 user's manual :) All the GPIOs, all the USB host specs, all SD host specs and so on... :cool:

[hey,i'm here]

hey guys, i don't even known that Hermes can boots Linux from a long time, and i've just come in here, but my English is so bad that i could not understan all you guys say, so can anyone give me a complete file to boot Linux on Hermes devices and intructions please, i'll verry appriciate that, all i want is using Linux as an G1 device on my T-mobile MDA Vario II, pleaseeeeeeeee, i'll wait for all of you

[utak3r]

You won't get anything similar to Android as for now... it won't be usable.

[utak3r]

Does someone get the console working? If so, could you provide either the proper haret config or the rootfs? Mine fails to get the control over the tty :/
Later, from telnet, when I do:

# echo "something" > /dev/console

it prints it on the lcd, so it's working... but if I change it in the config to use it, booting messages disappears and the screen becomes blank. So - have you some interesting rootfs to start from?


and my another question is: is there some manual on using haret's hardware monitor?

you should try this for the manual
http://www.handhelds.org/moin/moin.cgi/HaRET_20Documentation
although it may be old
you can use an initrd image or cross compile busybox to get minimal console
:D

well, I have built my own image, the problem is with the initial scripts, probably I screwed something. I'll rebuild it from scratch, maybe I missed something ;)

[elysion]

Hi!

Back here after over a year of absence. Seems like you guys have made some nice progress! Got the kernel built and running on my hermes. The problem now is that I don't have a working rootfs.

I have written a howto for building the current kernel sources available at linuxtogo. Where would be a good place to put this? I guess htc-linux.org/wiki might be a good place for the information, but for the project something more complex like launchpad project would be better. In my opinnion the problem with this project is that it is quite hard to get up-to-date information of it. A collaboration tool such as launchpad would be nice, where the current tasks and statuses could be reported. Now you have to browse through the forum here to find little shreds of information here and there.

First things that would be nice to have commented are:
* The current tasks with priorities
* Different solution suggestions of the problems listed with comments
* People working on the port
* A list that tells who to ask for info concerning specific part of the project would be nice. Also some info on the location of the people involved would be nice, so that one would know when and who to contact if problems emerge.
* Howtos
* Checking out the source, configuring the build and building it
* Making a rootfs

I would be very interested in taking part in this effort as I own a hermes PDA. I am finishing my MSc studies on software engineering, so I atleast should know a thing or two about embedded systems and coding. I would also be very interested in the organizing part of the project.

What do you think? How should we advance?

[utak3r]

Agree... I can think of SourceForge (although it runs these days horribly) or Google Code - both have enough tools to run such projects :)

[Oceanwatcher]

I might be asking a completely stupid question here... But would it not be better to look at trying to get Android to work on Hermes?

I have a TyTN and would love to see it refreshed with a new OS that really kick some... That would really extend the life of this phone! A lot of phones out there and it would generate a lot of publisity!

An Android image and a flash utility that runs on Windows, and Linux (Kubuntu if you ask me :-) ) so that it is possible even for my mom to do an upgrade. THAT would be something!

[utak3r]

The problem with Android is its instructions set.... :/
still - the road to it is pretty much the same - we have to get all the drivers working.

[Oceanwatcher]

Yeah, I guess the drivers will be the same anyway.

I am not a programmer, so I could not say too much about Android's instruction set, but using that instead of something that is "half done" would give us a more complete software for the phone as well as a bigger user community.

Also, there will be a lot of add-ons for Android judging by the interest in it. So I think that will be the way to go after the drivers has been sorted out, even if it might be a bit difficult. There should also be a lot of good help to get from other Android developers?

[scholbert]

Hi!

The problem with Android is its instructions set.... :/
still - the road to it is pretty much the same - we have to get all the drivers working.

No, that's no problem anymore. There had been a succesful port of android to the freerunner (openmoko.org).
This device uses the same SoC like hermes. Android is in a more or less useable state on this device.

To run android we will need quite nice implemented kernel, that's supports at least some of the main components of the hermes platform.

This is the main problem!
Development got stuck at some point, while integrating further parts that are essential for running a useful distribution on top of the hardware.
One of the most important thing is a working SD card driver, because it will be needed for the rootfs.

Unfortunately, the interface to SD is realized with the ATI imageon GPU.
Obviously no one ever managed to get enough information about this black box, neither managed to get any driver code to work.

Another big thing is the GSM chipset, this whole part is a mystery!
Though some basics are known, this is far away form working code.
The best guess would be the drivers for HTC universal, but no one ever tried to implement.

So honestly, if you're not a genius in reverse engineering or the god of WM dll-disassembly, forget about it. There are too many obstacles to get a useful linux running on hermes :(

Best regards,

scholbert

[elysion]

I would be interested in porting the SD reader driver to the hermes, but the tasks seems quite difficult as all the information is spread here and there. A project page where all the problems and solution suggestions would be documented should make the task at least a bit easier. Have the other port projects done something like that?

Yes there'd been some attempts for HTC Athena...
This device uses a similar chip from ATI (W2284) but i don't know the actual status of the port.

To get an idea of what is working/missing for hermes ...
I once tried to sum it in one of my former posts (no change from what i know...), have a look here:
http://forum.xda-developers.com/showpost.php?p=2863423&postcount=197

I also tried some hacking on this issue, but without succes. It's real hard, because so much is unknown and you'll have to investigate on every single bit :rolleyes:
Believe me, i really digged deep into hermes hardware, but it's too much...

Personally i really would appreciate to get some more comprehensive linux stuff rollin on the hermes, but i must admit that i feel time is to precious to do so :p

Have a look at one of the newer devices using MSM72xx, these linux ports are in much better shape and will get more devlopers involved!
At least that's all my point of view.
So if you like this mission do it, nothing is impossible :D

Cheers,

Best Regards,
Vivekanandan M
Yes the hardware is similar, but not the same.
In other words the kernel for Neo1973 won't work correctly on hermes.
If there would be a working kernel, Openmoko rootfs would be a starting point to get a useful linux.
Hermes uses the ATI GPU for interfacing to the SD-card and there's no working driver for this.
Also other parts are missing.....

These issues have already been discussed a lot :p
Please read the thread and you will learn more about the holy grail of hermes hardware and mystic linux kernels.

Cheers scholbert

[vivekanandan]

Hello Scholbert,

I am currently having some free time, so exploring the linux port for Herm.

I will spend some time reading all the postings in this thread.

Btw, I am also working on getting the drivers for all the components in Herm.

Best Regards,
Vivekanandan M

[chrs2021]

I am interested in this as well. is there anyone actively working on this?

[scholbert]

I am interested in this as well. is there anyone actively working on this?
All i can say is:
I am not and a useful kernel is far away.
The platform is too old already and the good hackers are gone.

If there'd been some bright spot on the missing drivers it would have been turned in another dimension....:o

But if you got some sparetimte, don't hesitate :D

Cheers,

[bally3]

Just throwing one in there.. but if theres interest in this project (and I dont mean "I would like to have it" I mean any devs still owning a hermes and would want to get involved, pm me and I'll see about putting some time into this.

The wife decided the hermes was too bulky for her and I'm now using it as my backup phone when my polaris is "busy" which it is often :rolleyes:

I'm quite impressed with it, barring a few memory niggles.

Anyway, any dev support, pm me. If not its still good with WinMo as it is.

one reply since I posted, I assume theres little or no interest in this project.. oh well! :rolleyes:

For anyone interested, I'm looking at recompiling the current kernel. Pof rightly pointed on the first post that the 2.6 kernels do indeed come with support for the samsung chip.

There are options in the kernel source to turn on the chipset support so I'll start with that with my first compile hopefuully this week.

Anyone interested in joining in, there is a detailed howto compile a kernel here:

http://www.androidonhtc.com/get_involved

Compiling the kernel is fairly simple as long as you have a linux install either native or running as a virtual machine (vm). Easiest way to do that is download virtualbox (http://www.virtualbox.org/wiki/Downloads) and a linux iso image - I recomnend ubuntu (http://www.google.co.uk/url?q=http://www.ubuntu.com/GetUbuntu/download&ei=9G-rSoSDKduhjAf8iPXdBw&sa=X&oi=smap&resnum=1&ct=result&cd=1&usg=AFQjCNFvEWQWd80BzznT1K4VVhWem4zCSA) or any debian flavour as there seems to more info for android for them. Setting up a vm with virtualbox is a breeze (really is, if you cant do that then linux devving isnt for you). But to make it even easier, heres a video (http://www.virtualbox.org/wiki/VirtualBoxTV) how to do it - simple! :p

Of course, if you run linux then you dont need a vm set up (but you already now that of course).

So now you've got the vm set up and you've followed the instructions to download the kernel source, you're ready to compile your first kernel and claim your fame to be a rookie dev!

When I get myself set up again, I'll talk it through step-by-step what I've learnt, theres some additional dev help that can be had on the POLARIS_DEV irc room in my signature if you want to pop in and speak to me - usually after 6pm BST.

If you're interested at all, I would recommend getting this set up first and we can get together and discuss what to do next - Good luck!

[vivekanandan]

Hello,

I have already downloaded the linux kernel sources 2.6 and built the kernel for Herm and was able to boot my device with linux!

I know some linux based pda's that has Imageon gpu and run linux 2.4! Why dont we port the imageon drivers for linux 2.4 to linux 2.6.

I will be interested to spend some time to make linux run completely in Herm device.

400/500 MHz Samsung 2442B Processor/SOC (400 minimum, ARM920T core, ARMv4T)

Can you post up the kernel yo compile and the options you used to do it so I can kick start some progress with it? and where did you get your kernel source from please?

Thank you.

Ok so not a good start then as no-one seems to be that interested :confused:

Surely there must be some devs out there with these phones as backups like me that would like to see Android running on here?

I've had some bad luck with my linux lappy recently which forced me to reload the distro and start from scratch again which is a general pain.

I will be downloading the sources and try a compile with the samsung chipset support enabled and see how I go,

Really.. REALLY would appreciate some devs coming forward though!

Hi bally3,

yes you are right the interest has gone and also the kernel kackers have given up.
It's very too hard to reverse engineer a chip you got at least no information about (ATI2282).
I fiddled around with this device some time ago, so ignore all these noob suggestions to try this, or try that, because it looks like similar hardware...
There's much more to do, believe me!

Anyway there's a booting kernel as well as simple framebuffer support.
Unfortunately all the cracks are gone... and i'm a bad kernel hacker :p
You may find a lot of useful information floating around in this thread.
Maybe i could give some answers too.

I suggest starting here:

You may also take a look my posts following up.
There's also a working kernel + configuration.

[vletrmx21]

I would absolutely love to see this working one day on my hermes, but I can imagine the work that needs to go in, all I can say if, if you need some guinea pigs to tests your builds hit me up!

There seems to have been a conversation recently on this thread too:
