Amlogic has just released buildroot with Linux 3.14 with support for Amlogic S905X (p212 board), S905D (p230 board), and S912 (Q200 board) processors, and the company appears to have started working on Linux 4.4 likely for future support for Android 7.0.
You can check the source code as follows:
|
1 2 3 |
wget -c http://openlinux.amlogic.com:8000/download/ARM/filesystem/arm-buildroot-2016-08-18-5aaca1b35f.tar.gz tar xf arm-buildroot-2016-08-18-5aaca1b35f.tar.gz cd buildroot |
If you have the wrong toolchain the code won’t build (See comments section). So I installed several toolchains provided by Amlogic (all may not be needed) in /opt:
|
1 2 3 4 5 6 7 8 9 10 |
wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar wget -c http://openlinux.amlogic.com:8000/deploy/gcc-linaro-arm-linux-gnueabihf.tar.gz wget -c http://openlinux.amlogic.com:8000/deploy/arc-4.8-amlogic-20130904-r2.tar.gz wget -c http://openlinux.amlogic.com:8000/deploy/CodeSourcery.tar.gz sudo tar xvf gcc-linaro-aarch64-linux-gnu-4.9-2014.09_linux.tar -C /opt sudo tar xvf gcc-linaro-aarch64-none-elf-4.8-2013.11_linux.tar.bz2 -C /opt sudo tar xvf arc-4.8-amlogic-20130904-r2.tar.gz -C /opt sudo tar xvf gcc-linaro-arm-linux-gnueabihf.tar.gz -C /opt sudo tar xvf CodeSourcery.tar.gz -C /opt |
I also downloaded a shell script to add the toolchains to my path:
|
1 2 |
wget http://openlinux.amlogic.com:8000/deploy/TOOLSENV.sh source TOOLSENV.sh |
Once toolchains are setup, you can select one of three boards config (Q200 / S912 as example) and start building the code:
|
1 2 3 |
sudo apt install build-essential make mesongxm_q200_release_defconfig make |
If you are interested in S905X or S905D instead, use respectively mesongxl_p212_release_defconfig or mesongxl_p230_release_defconfig.
I built both S912:

Separately, you can also find buildroot for Linux 4.4, but this is very likely very early work, and should be used together with Amlogic Android 7.0 SDK once it is released.
