[GT-P6210][KERNEL][UV/OC]garyd9's GT-P6210 kernel (updated 2012-01-23)

will this get me there?

git clone git://android.git.kernel.org/platform/prebuilt.git

export ARCH=arm
export CROSS_COMPILE=arm-eabi-
export PATH=$PATH:~/toolchain/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/[/QUOTE]

Link did not work, so I'm doing this:
git clone https://android.git.kernel.org/platform/prebuilt.git

At 64%, going to bed, look at it some more tomorrow.

Gary,
I have spent many fruitless hours trying to find anything on the Galaxy SII that relates to the above mentioned toolchain and instructions. Lastnight I followed these instructions from this site:http://wiki.cyanogenmod.com/wiki/Building_Kernel_from_source#Download_Kernel_Source_Code
resulting in this final command: export CCOMPILER=${HOME}/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.0/bin/arm-eabi-

...but this is 4.4.0 and not 4.4.3

I must be missing something simple, looking right at it and not seeing it. Could you give me a little nudge?

Chip

make menuconfig ARCH=arm

When I run this command I get a GUI in the terminal, not sure what to choose or just to accept the defaults. I attached a screen shot.

I'm going to jump around a bit, as I really need to run out and get some stuff done today, but the kernel image will be located in arch/arm/boot and called "zImage"

I ran the ./build_p6210_kernel, I got the spam. Cannot find zImage.

Ran out of space on my Linux box, short sighted of me I know, but I had several gig available when I started this project. Machine resisted all efforts to expand partition, I don't think I left it enough room to even remove anything. Could not revert to snapshot because had to delete that in order to attempt the resize. Didn't want to abandon all the work I had already done. Oh, well started over with new machine, this one has a 40 GB drive. Installed all the prerequisites, except sun-java6-jdk, kept getting error, looked all over the net, added repositories, clean sources list, everything, finally tried openjdk. Opened terminal and:
mkdir -p ~/android/system
cd ~/android/system
repo init -u git://github.com/CyanogenMod/android.git -b gingerbread
repo sync -j8
It ran for HOURS. Again. Then failed: error: RPC failed; result=18, HTTP code = 200. No explanation, no recourse, nothing, just hours of data that didn't go anywhere. I searched the drive, found a folder, Android, not much in it.
Breaks my heart. Starting over.

Hi Gary! I got my machine back together again, using the toolchain from NDK since I had to install all the SDK stuff to make ADB work on this thing anyway. I edited the "build_p6210_kernel" file to look for the NDK toolchain instead of the cyanogen one. I stopped getting toolchain issues when I moved the folder to "root", now I'm getting errors dealing with the "initramfs". Could you glance over this output and see if something jumps out at you? I feel like I am really close this time.

Did not have lzma installed, some sort of compression utility. Trying again...

Woohoo! I have zImage!

Well Gary, I tweaked your kernel. Added support for USB wireless, Everything still appears stable. Device still shows no wireless extensions for usb0. I'm still missing something. Maybe a wifi module?

garyd9 said:

First, you need a compiler and toolchain. Samsung likes to use v4.4.3 of gcc, and we're kind of stuck for that in order to let things work properly with the ar6000.ko precompiled kernel module. The easiest way to get that is to take a few steps back and search for cyanogenmod. If you search, you'll find official cyanogenmod instructions for getting the code for and building for the Samsung Galaxy SII. That has the same CPU as this tablet, so get for it. Don't worry about getting any prebuild modules - we aren't actually compiling for the SGII.. we just want the 4.4.3 toolchain that comes with it. (Among tons of other garbage, make sure this leaves you with a file similar to ~/android/system/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin/arm-eabi-gcc ) (You can also get this toolchain from the android ndk or from pulling the latest ICS sources from google... ) Following the directions for getting the cyanogenmod stuff will also ensure you have other tools installed on your machine as needed...

I just realized that kernels built using a compiler other than GCC 4.4.3 break the baseband on my P6200. I had read that the prebuilt Atheros wireless module would break, but it was working for me, so I just kept on compiling with Linaro 4.6, etc, frustrated as hell.

On a hunch I recompiled with GCC 4.4.3 from the Android NDK and everything's working now. I feel like a retard. That should teach me to live on the bleeding edge.

Back to hacking. When are we gonna start porting CM9? I'm game!

please please please port cm9!!! I wish I had the skills (or the time to acquire the skills) to get it done!

Sorry I read through both this and your root thread and haven't come up with the answer. The firmware is listed in device settings right? So if the build ends with P6210XXLB2, I have LB2 firmware?

Does anybody know if LB2 is post-LA3, and therefore probably won't work with this kernel?

Thanks!

Me to CM9 would be awesome Gary and your the only one with the brains around here. I'll gladly pay for your time

I do mean to bring up the money thing bud BUT I really don't have anything else I can offer. I'm learning Android on my days off so hopefully one day I can contribute to coding. Thanks Gary
