ok, could you try razr's ducati_m3.bin which i had attached?
and, how to distinguish ducati_m3.bin isn't use gptimer 11?
if i found a rom that is kernel3.x and ics and omap4430, it should be not use gptimer 11?

I believe the back light is using timer 11, which is stated in the op that ducati and back light won't work at the same time.

If you found source for devices with kernel 3.x support, you can see this file
arch/arm/mach-omap2/remoteproc.c
In code found declaration
If you see number 11 you can forget for this device.
arch/arm/mach-omap2/remoteproc.c
In code found declaration
Code:
static struct omap_rproc_timers_info ipu_timers[] = {
{ .id = 3 },
{ .id = 4 },
#ifdef CONFIG_REMOTEPROC_WATCHDOG
{ .id = 9 },
[B] { .id = 11 },[/B]
#endif
};Unless the sources are not available yet, maybe Kuzma could try its Ducati binary if you upload it.
sound
Hi Kuzma,
check the kernel tree. I think I found a missing sound bit and got it working now. It was just a name of a mixer device. Otherwise, hats off, Kuzma. You nailed it

next up, stability?
Nice job to both of you... so it seems that aside from stability and the backlight dimming, 3.x is just about at parity with 2.6.35. We know what's wrong with ducatimm... so things are proceeding very nicely
As far as the stability goes-- chrmhoffmann said he's getting regular crashes but doesn't have a serial and nothing showing up on last_kmsg. Are you getting the same crashes, kuzma30, and if so, what's being reported?

I think I fix crashes audio (latest commits in github). Need test.
Next step is backlight and panel driver power up, resume/ sleep procedure (after applying DSI2 patch this need rework).

sorry for my many questions...
why it can use gptimer11? because it hardware design was different with our NT?

Fyi, GPIO 121 is muxed to gptimer11 PWM event. Kuzma30 and crew are still tweaking the backlight driver to work correctly, but its using PWM.

This is an issue with cm7 as well. I believe it is caused by hardware limitations. If you do a software reboot, the ext SD will not be recognized unless you pop it out and reinsert it. This occurs both within cm7 and cwm recovery.
A full shutdown and power up does not cause the issue.

I've started porting 3.0.x Android kernel to NookTablet.
CURRENT LOG:
http://pastebin.com/qWXL5LuG
Working /Not working features:
1. external SD card (thanks fattire), internal emmc works!
2. LCD screen (working), back-light(always on as temporary hack). Tested backlight without loading ducati-m3.bin - it works. Thanks to icemank121 in IRC for recommending Hashcode to check the Archos Gen 9 tablet's backlight driver and mik_os for adaptation for NT.
3. Touchscreen (enabled)
4. G-sensor (enabled)
5. Battery driver (enabled)
6. Audio driver (enabled, working). Thanks to chrmhoffmann.
7. WIFI (working).
8. ADB works (test with CWM)
9. Booting without rootfs in RAM. Ready for beta testing Ubuntu/Linux boot. http://xdaforums.com/showpost.php?p=23072540&postcount=119
10. power button works in ICS. Poweroff working now. Thanks to Hashcode.
11. Ducati don't work if backlight is working. (Timer 11 conflict)
12. Add USB OTG driver to the kernel / don't have USB OTG cable to test
13. Charger working with USB/wall charger.
14. After software reset SD card don't recognized before shutdown. Fixed by mik_os.
15. NT reboot only when USB cable is connected http://xdaforums.com/showpost.php?p=25749805&postcount=419
Fixed. Tnahks to Rebellos and mik_os (http://xdaforums.com/showpost.php?p=25791963&postcount=426)
16. Deep sleep working, but drain 2-3%/h
17. Skype working for me now! Testing with 2 my skype account.[/COLOR] It working on buildin mic and headset mic too. Headset tested by joelee100. On test branch using of mic cause device reboot.
18. Test HD video on YouTube on 16gb device. It working now. Thanks to HashCode to consulting
Test release CM9 is here http://xdaforums.com/showpost.php?p=26762846&postcount=503
The repositorie is here https://github.com/Kuzma30/kernel3NookTablet
Some features are disabled. I will enable them, one by one.
Help is greatly appreciated!
This is beta version of 3.x kernel. Only for development use (yet)!

So "compiling" as you may know is the process of taking human-readable code (or at least computer-programmer-human readable, it's not like a Steven King story) and converting it into a binary blob of code that can be processed and interpreted by the silicon chips in the computer. That translation is compiling, and there are several steps to it...
What you're looking at in Kuzma's post isn't actual code, but a log of output showing the process of booting the kernel-- the kernel being the most "low-level" program that runs on the nook tablet. The Android kernel, based on the Linux kernel, is in charge of ensuring all the other programs get CPU time to run, and it oversees all the basic systems and all the hardware and everything at the most fundamental level. It's super complex. To use a bizarre analogy-- if a regular app you'd use in Android is as intricate as a shopping mall, I'd say the kernel's inner workings are about as complex as the city of Manhattan.
The Nook Tablet's stock system comes with the 2.6.35 version kernel. However, that kernel is fairly old as kernels go. The newer 3.2.x kernels have been souped up by Texas Instruments (who make the OMAP4 platform upon which the Nook Tablet is based). These OMAP-specific enhancements add things to make the Nook Tablet be able to do super-fast graphic effects, play hardware-accelerated video, and offload processing from the CPU to other chips and save power in other ways. The 3.x kernels also have other improvements that Ice Cream Sandwich depends on for stuff like the network auditing (where you can see how many MB you download in a nice graph and automatically stop it from exceeding a limit).
So for the past few weeks, hashcode, chrmhoffman, nemith, myself, and others have been moving features back from the 3.x kernel to the NT's 2.6.35 kernel because it's generally easier to grab a feature at a time and integrate it back. But going the other way is a much better if not harder way of doing it-- Kuzma's jumping to to the latest version from TI, then then grab all the 2.6.35 NT-specific code (such as touchscreen drivers, and SD cards and other peripherals and settings) and moving them forward into the newest kernel so it's "caught up".
But to do this, you have to more or less work "blind" because you don't have a working screen to even see errors or to know if things are working or not. You just pop in the new kernel file, turn it on, and cross your fingers that everything will work out perfectly.
No not really. That would never work. Instead, you need a way to see what's going on. And so you need to "tap" the physical hardware by connecting up some wires to the NT so it'll send a signal to your computer showing you what's happening with the kernel as you boot it on the NT-- whether the code you've changed is working or not.
That's what the log above represents-- it's the output of the boot process, which shows various parts of the Nook Tablet starting up in the 3.x kernel-- this is the actual output of the kernel when it runs. Normally this output is "hidden" from view-- it's only viewable when you type the "dmesg" command in the shell. But he's tapped the internals of the Nook Tablet and is able to view it and log it and show it to us.
And he's saying that he's having problems with registering the external MMC, also known as the "SD card". And so then he shows the part of the code in the kernel that is producing the error.
The kernel is written in the C language, which is perhaps not the first one I'd recommend if you want to get your feet wet with this stuff. Instead, I'd take a look at python as a language. It's meant to be an easy language to learn, it's available free, it runs on everything from Macs to Linux to Windows to Android. It also happens to be very very very powerful and is used everywhere from NASA to the stock market to writing games. It's not a toy, even though children can learn it quickly.
Which is why I'm going to recommend the book "Hello World" for you to check out. It's a great book written for kids, but I think it's a good place for you to start. I have nothing to do with it, just a fan and I've recommended it to others with good results.
Hope this gives the discussion some context.33I have some very good news.
We may finally have the opportunity to have ducati-m3.bin with GPTimer 9, 10 as WDT.
It will take some days or weeks from now, so be patient.
As i have some more news will post back.
Thats all am allowed to say in time being.
Keep your hope up guys we may finally have video acceleration on ICS!24
Would you ask a writer why they dont just release part of their next book? Would you ask a painter to display a 1/2 finished work of art?
This is the right way to do it. Anything else would be a hack. Porting the kernel over gives us a reference point to start with. You can pretty much assume that any custom kernel to come in the future will be based on work that is going on right here, right now.
Please be considerate and do not clutter this thread with "Im impatient and i want somethimg now". Ive got work to do on Ubuntu as soon as this kernel is finished. CM9 will use this kernel when it is finished. Its likely that Barnes & Noble will use this kernel when its finished and will be asking for help and/or hiring those who did most of the work.
Just hold your horses guy. We all want something new. You can build and test... You can research... You can try to understand... But please, dont rush perfection. Have respect for the work being done here and if you must, send a pm with a request. This is true development.
