Rockchip RK3188 Linux Source Code is Now Available

Good news! I’ve just read Rockchip RK3188 Linux source code has just been released via Rikomagic, and Alok Sinha, the main maintainer of RK3066 source code, has already imported into github, and we should soon see a PicUntu image for RK3188 mini PCs.

Let’s have a look:

git clone git://github.com/aloksinha2001/Linux3188.git
cd Linux3188

1 2	git clone git://github.com/aloksinha2001/Linux3188.git cd Linux3188

[Update: you may have to run “sudo apt-get install libc6-i386” before running make_kernel_ruikemei.sh below, as mkkrnlimg is a 32-bit binary]

Usually, I immediately look into arch/arm/configs, but this time, there’s a “funny” script called make_kernel_ruikemei.sh, and .config already have some CONFIG_RK3188, so let’s run it:

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabihf-
./make_kernel_ruikemei.sh

export ARCH=arm

export CROSS_COMPILE=arm-linux-gnueabihf-

./make_kernel_ruikemei.sh

After just over a minute, success!:

kernel Image:/home/jaufranc/edev/sandbox/rk3188/Linux3188/kernel.img for mid is ready.

Image: kernel.img is ready

This kernel image is for Android only, and there’s a little work to modify it as a “pure” Linux kernel, so that it can be used to boot PicUnutu for RK3188.

Let’s go back to arch/arm/configs, and we’ll find several RK3188 configs:

rk3168_86v_defconfig
rk3188_dongle_defconfig
rk3188_ds1006h_defconfig
rk3188_ds1006h_v1_0_defconfig
rk3188_hotdog_defconfig
rk3188_LR097_defconfig
rk3188_magicwand_defconfig
rk3188_steak_defconfig

However, in arch/arm/mach, there are only board files for rk3188-box and rk3188-ds1006h.
