And the source code :)

A really really good work...

When have some time will use it.

Just read through this thread, and I must say that you've done some brilliant work Eduardo! Like most of the others it's way over my head, but just to let you know your hard work is greatly appreciated! Many thanks :)

Can this help us?

Because it´s based on 2.6.38 and there are drivers for that kernel in the release.

New Linux for Tegra release 12

Excellent!! - I think that this can be a very good reason to port the .36 kernel drivers to .38 ... Finally, accelerated X... I can barely believe it... And that is exactly what i was looking for... :)

July 1, 2011

I´m very excited to see what you can do with it. :)

July 2, 2011

Eduardo, GREAT WORK!!!

July 2, 2011

And the source code :)

A home run!!

Any chance you might start posting your work on GitHub?

This is world class work on your part.

=====================================

UPDATE:
-Sound is working!!!
-Including autoswitching between speaker and headphone, when a headphone is plugged or unplugged.

=====================================

So, all the required Tegra2 configurations to make all the P10AN01 hardware work should be right and working :blink:

Attached, the latest files (copy over craskman git), and my precompiled boot image

Let the fun begin!

Hi,

i played a little with your kernel and boot.img.

Are you able to mount a mtdblock ?

I´m not, it give me segmention fault when i try it.

Well, i had no problem mounting the mtdblock ... no problems at all... did you get the segmentation fault while mounting, or while reading or while writing to the mtd ?

Lately, i ran out of time (being busy with other things), that is why there were no updates ... And, here is where, in fact, what i can do regarding kernel development dimishes a lot... The fact that i am unable to reproduce the bugs makes it very hard to fix eventual problems...

BTW, i will iinsist: The toolchain used to compile the kernel is extremely critical... 4.4.0 as supplied with the android ndk worked for me, but no other did.... Random crashes with all the newer versions...

A little tip: The mtd partition sizes are hardcoded in the kernel... I don't know if using the linux kernel command line it is possible or not to override those partition sizes. But, certainly, some parameters from the previous kernel will cause trouble... I suggert using the same command line as a use ... means, a null command line, or, perhaps, a command line that just sets the console.

Regards,

Eduardo

Hi Guys, has been a while.

Have anyone been successful on running any version of Android with this kernel?

If not, which issues are you facing?

Can you share the ROM? Can you provide more details?

Erm... Is this with 2.6.36 kernel? You have managed to get an image booting using this kernel? If so, Could you PLEASE post your boot.img for me?

July 16, 2011

Hi,

It is the 2.6.36 kernel from Eduardo. But you need a partioned sdcard, i boot it from there because the space in nand is so limited and it is very easy to exchange files without flash it every time.

I will clean the ramdisk and post the boot image with instructions later here.

Yes, possibly. Do you use gtalk? Touchscreen config files are in /system/usr/idc if you copy the IT** config file from VegaComb (I forget the exat name of the file! :P) then you should be able to get the touchscreen working! If you need anything else drop me a message or hit me up on gtalk, I can PM you my google address if you want to talk on there!


Also, I can make it fit in NAND no problem, so we might as well use VC as a base ;)

Hi,

thank´s for the tip with the touchscreen file.

It works now. I can say, it run very very smooth.

When I have network working, i will post more.

cu. rebel1 / Rene

P.S.: @newbe5 , you are connected with me over google+

July 17, 2011

Please share that boot.img...

Here it´s the boot.img

Don´t forget that yo need to edit the ramdisk, because i'm booting from sdcard,

July 17, 2011

thanks rebel, you have beaten me to geting this running. i've battled hard drive problems and some faulty memory and when i'm up and running again you have posted a new boot.I mg.

great job, i'll look at it tonight and see where can get to.

Hi,

this is the system.img, that i boot from my sdcard.

Iconia system.img

July 17, 2011

rebel1,

Unpacked your boot.img and replaced the ramdisk with the 'stock' vegacomb one. Added to 1.7 vegacomb and flash the tablet.

Got corrupt screen green and red lines then grey screen. Now I need to get the windows pc running again so I can nvflash it again.

Unless you have any great tips on how to do this via Linux.

I will have a look at the ROM you have uploaded and I'll try to strip in down ("a lot") for you.

Billy..
