How to compile your own kernel for rk3066 devices

[leolas]

Re: How to compile your own kernel for rk3066 devices

Tried a compiled kernel with the Finless 2.1 rom for the MK808b and there were display problems (although the android booted up and showed the launcher selection screen.

Triend again with Finless 1.6 and it booted up properly with working display. No bluetooth and wifi.

For the 4.2 roms we need to use the new 3.0.36 sources, actually noone got it working in android, but in picuntu they boots very well.
To find the new kernel sources search for galland or the new branch of omegamoon. I am in the bed now, tomorrow i will try to post the links to the new sources.

PS: The new sources for rk3066 kernels are in:

https://github.com/omegamoon/rockchip-rk30xx-mk808/tree/rk3x-3.0.36+

https://github.com/Galland/rk3x_kernel_3.0.36

I cant make them to boot in android, and no way to check where they fail, same kernel boot in picuntu very well

Thanks leolas.

BTW where is the thread (on this forum or elsewhere) where you are trying to develop a working kernel for mk808b. I would like to help out if possible.

I didn't post it in any place. But we will found the same problem with this sources than with the 3.0.8, we lost wifi and bt with custom kernel. At least in my working kernel in picuntu i lost them.
Like i said before no way to make this kernel sources work in android for me.
If you have familiarity about compiling kernels and i can assist you in something, only tell me. If you search in google about omegamoon blog, there is some info there. In armtvtech there is some old info too.
My experience compiling kernels are only with linux a few months ago, and modify code is out of my possibilities.
I will give you some links when i can sit in my pc.

Completed your steps outlined above for building an Ubuntu VM and have the sources installed etc. (I have a brand-new 808B that I can kick the tires on.)

Really appreciate all the work that obviously went into this!

I have my first compile complete w/o errors. Ready to add to the update zip. Wanting to open up the official 4.2.2 rom though and fix some issues there before I test with this kernel?

Anyone have a fix list of items I can try to include? I know there is a gameloft fix and things with device settings etc that Finless usually does. Do I just need to open his rom and poke around. Thanks much to Finless, Leolas and all the folks helping with this!

RK3066 kernel sources from Archos

Archos has a few products with RK3066 and is also providing kernel sources. Family Pad 2 I know for sure is an RK3066 platform and assuming these products are often verry close to the Rockchip's reference platform it might be a good reference for kernel sources. You can find this kernel along with all other Archos products at http://www.archos.com/us/support/sup...dates_gnu.html

Can someone reupload scripts.zip archive, because link is dead. I need this package to compile rk3066 kernel.

RK3066 Linux Kernel Sources

(if anyone can modify this source code or the config files to compile a kernel for Android from this I'd be very grateful)

Android 3.0.72 Kernel Sources

https://github.com/Galland/Rockchip-GPL-Kernel

You have to put the Nand.ko.3.0.72 file in your boot image and the other 3.0.72 modules into the system/lib/modules folder.

Use these instructions to build, can even copy into a file and rename it to *.sh and make it executable to work as a script.

https://github.com/omegamoon/rockchip-rk30xx-mk808/blob/master/build_mk808_omegamoon

Copy this folder to your kernel source folder
https://github.com/omegamoon/rockchi...ster/omegamoon to get the toolchain required in above step.

For config files you need a MK808_defconfig, copy one from https://github.com/omegamoon/rockchi...ch/arm/configs or a new one from https://drive.google.com/file/d/0B2J...it?usp=sharing
Type 'TOOLCHAIN=./omegamoon/toolchain/arm-linux-androideabi-4.6/prebuilt/linux-x86/bin/arm-linux-androideabi-'
Then type 'ARCH=arm CROSS_COMPILE=$TOOLCHAIN make mk808_defconfig' for example to copy that device info to the config file.
Then type 'make menuconfig' to change settings related to that device.
Then type 'make' to compile the kernel.
'make modules'
'make INSTALL_MOD_PATH=MODULES modules_install'

Hi i've kernel source for my GoClever R974.2 and i don't know which kernel version is it. My question is how can i build it with CPU and GPU OverClocking ... can someone help me with this?. Kernel source http://openlinux.goclever.com/R83x_R973_R974x/

Hello all,

I am trying to build my own kernel for a week now, long hours and les sleep
Before i modify something i have to get it working.
The goal is to make custom kernels soon and learn how they work.

All kernels i build do not boot ( no hdmi output ), whan can be the cuase?

What i do:
I dedicated my new labtop to linux so no VM, running Ubuntu 12.04 LTS 64bit
cloned the githubs from omegamoon, andrewDB, Alok etc..
To be sure i get somethin working i took the .config from a working kernel that was build from the same source:

adb pull /proc/config.gz

Unpacked it and copied it to ./arch/arm/config and renamed it to test_defconfig.

Using the toolchain from omegamoon:

export ARCH=arm
export CROSS_COMPILE=~/android/kernel/toolchains/arm-eabi-linaro-4.6.2/bin/arm-eabi-

make test_defconfig
make


./rkcrc -k ./arch/arm/boot/zImage ./kernel.img

Also tried all predefined xxx_defconfig people say report working.....
... Yes spend many days figuring it out...
Compiling without errors, and got a .img.
But every time i flash it it does not boot.
One thing i noticed the original was 3.7MB, the new is 3.6MB. ( am i missing something? )

Any idea?

BTW: i tried with all sources i got my hands on and all got the same result.
Do i miss something to get a proper android bootable .IMG or do we need to do something to zImage/Image before i can flash it?
The image size is 3.6MB so fits the partition.
It looks like the stick dont see the Kernel, like it does not exist or cant read it.
When flashing back the original it works again.

Is there a way to debug a booting kernel? and see if it actualy boots or not?

Any ideas?

help

Can anyone help: I'm using kernel sources from http://openlinux.goclever.com/R104/
(I also added https://raw.github.com/omegamoon/roc.../vpu_service.c to arch/arm/plat-rk folder)
toolchains from: https://github.com/DooMLoRD/android_...toolchains.git

export ARCH=arm
export PATH=$PATH:~/android/kernels/toolchains/arm-eabi-linaro-4.6.2/bin/
export CROSS_COMPILE=arm-eabi-

then
make rk2926_sdk_defconfig
make

after a while I am getting

...
CC lib/vsprintf.o
AR lib/lib.a
LD vmlinux.o
arm-eabi-ld: cannot find kernel/built-in.o: No such file or directory
make: *** [vmlinux.o] Error 1

And theres no kernel/built-in.o. But why does this happen?

What device? And what kernel you try? A kernel for Linux or android? Did you use same kernel version and extraversion that your rknand KO module?

Something is wrong with your toolchain.
