These are some of the Kaiser's internals.

Here you will find the diagram of it:

Lemme know what you guys think!

interesting that its chip supports video out but they did not add it in the hardware.

yes, the chip in the 8525/TyTN supported gps but did not support it.

the mogul has the 7500 chip which supports the same as the kaiser but the device doesnt support it all.

Interesting - this chipset has HSUPA support by default, but Kaiser doesn't support it (or at least, HTC does not confirm this). Does it mean that Kaiser has limited edition of that chipset, or maybe HSUPA will become available with future ROM updates from HTC?

I am sure this has to do with the carriers network supporting this bandwith upload feature.

Well, everything will turn out once Kaiser will hit the shelves and people start using it, and sharing (hopefully) their thoughts about it...

I suspect this will have a lot more to do with Microsoft's WM6 not ready to cope with these kind of 3,5G / 3,75G protocols.... (correct me if i'm wrong)
So that should also mean that future upgrades (AKU's i'd suspect) might correct the lack of HSUPA :cool:

As per the comment above, I definitely think it is based on the carrier.

The radio on kaiser runs L4/Linux Pistachio microkernel, you can read more information here (http://www.ertos.nicta.com.au/research/l4/).

Some pr0n for the linux geeks:

Thanks for this info! I am reading over it now.

[KaiserLinux]

im a bit confused on how it could run the l4 microkernel and windows 6 on it. I was hoping that I could somehow flash the device with a Linux embedded bootloader - > load a kernel that has support for both of these arm cpu's and board -> then load driver modules for all of the different radios and interfaces and drop some minimalistic OS on top of that. Does anyone know the feasibility of accomplishing something like this? Also how the l4 linux kernel can run side by side with wm6?

[robbiesz]

Think of the radio interface as a computer inside an another computer (the phone itself). The main CPU runs WM6 and interfaces with the radio which runs an embedded linux.

[Shadowmite]

Wrong, on most phones you are correct, they have a cpu and the seperate communications processor. But the kaiser is unique in using the communications processor as the primary CPU for the entire device. So unless there is a seperate arm core (dual core?) inside it, how is it running both linux and wm?

[KaiserLinux]

That's the thing that is very interesting. Looking at the diagram the msm7200 board seems to have an ARM11 and an ARM9 cpu on it.

[HTCFAN0923]

I coudlv'e sworn someone said that it might be a dual core...

[cr2]

Also how the l4 linux kernel can run side by side with wm6?

They can share address space on the same CPU,
wince is a 25bit OS.
Do you have the Kaiser phone ? Can you run haret on it ?

[robbiesz]

On handhelds.org it's mentioned that a guy named Kevin has modded the source code of haret for the MSM7500 chip. It's not working yet (internals of the chip is unknown), only the CPU gets detected. (more info: http://handhelds.org/moin/moin.cgi/HaRET)

As per the comment above, I definitely think it is based on the carrier.
HSUPA is mostly being trialled by carriers. Most are still absorbing HSDPA.

Hey - Im a nubee and I was wandering if any of you can help with what you estimate the cost of the Qualcomm MSM7200 SOC to be. Its very impressive!

We are starting a new design and could be interseting.

It still has a seperate communications processor, it's just in the same chip as opposed to a seperate package now. (See other comments).

I think it's something like 400 MHz ARM11 for applications, 274MHz ARM9 for comms.

[varmatheone]

Lets start an effort to try to run Android on kaiser? I am sure it will be a huge task, but lets give it a shot.

I am not an embedded system expert, but I am sure we can get people to help us, maybe from the google team once we get serious.

Kind of interesting: in the section "connectivity" there is a rectangle marked "USBOTG". If I am reading it right, this possibly means "USB OnTheGo", thus ability to make use of external USB storage ;-)

Another feature that's not being utilized...

[mav42]

Just went to the website indicated as this is what i saw::::::




Out of an abundance of caution, due to the December 31st, 2007 injunction ordered against certain Qualcomm products, Qualcomm has temporarily removed certain web content until it can be reviewed and modified if necessary to ensure compliance with the injunction. It may be several more days or weeks before these pages are accessible again. Thank you for your patience.


Injuction?????? could this be the reason why????????

[diablokev87]

Is it possible that someone that has saved the data sheets can post them in this thread. Thanks

[zenos1]

I was looking around for any information that would be helpful because I am interested in this project. I found this blog post that I find to be very interesting and helpful. :D

Tell me what you think.

It appears that the Sierra Wireless card uses the msm7200 chipset that is found in the Kaiser. Not only that, but their is a driver for Mac computers to use the card. I have downloaded the driver and you can see the page here:
http://www.edgemanuals.com/2008/02/04/sierra-wireless-aircard-880/

http://www.sierrawireless.com/support/support_and_downloads.aspx?id=20,9,1,2

http://www.sierrawireless.com/product/AC880_AC881.aspx

I wonder how long it will be before they take this down.

Shit I just found this as well:
http://www.sierrawireless.com/faq/ShowFAQ.aspx?ID=1076

[moegdaog]

if it uses the same chipset...what will this driver do? is this the holy grail of drivers for the kaiser?

[ChumleyEX]

Dude he's talking about wireless stuff not video. From what I can tell he just found drivers for linux and Mac OS so that we may now install them onto this phone. That is if we have linux or Mac OS to install on it.

[KaiserLinux]

Or we can glean the information from the drivers, kernel patch, at commands to get the radios to work. Apparently the GSM, 3G stuff, GPSone is what the sierra 880 card supports. so by just looking at the source code, we may be able to glean values that we were missing to have linux boot natively on the kaiser then access the radios directly.(-minus window mobile 6)

[stepw]

Radio must be controlled on Sierra device by embedded firmware which potentially has little in common with Kaiser's other than Qualcomm core.
Researching WM6 radio drivers would be more efficient IMO

[support]

Kaiser have 400 Mhz Dual Core application Processor :D

I found this information from Microsoft website :D
