For OGA/OGS/MAX/MAX2.

Build

• On Ubuntu desktop

Required packages

sudo apt-get update && sudo apt-get install -y git lzop build-essential gcc bc libncurses5-dev libc6-i386 lib32stdc++6 zlib1g:i386 p7zip-full p7zip-rar libssl-dev python-is-python3

Toolchain 6.3.1

sudo mkdir -p /opt/toolchains && wget https://releases.linaro.org/components/toolchain/binaries/6.3-2017.05/aarch64-linux-gnu/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz && sudo tar Jxvf gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu.tar.xz -C /opt/toolchains/

Add lines below to ~/.bashrc

export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
export PATH=/opt/toolchains/gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu/bin/:$PATH

Run the command below to apply the setting.

source ~/.bashrc

Verify the toolchain version to confirm compatibility. It should show gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05) in the last line output below Thread model.

aarch64-linux-gnu-gcc -v

Clone this git and build the kernel

git clone --recursive https://github.com/JuanMiguelBG/rgb10max-linux.git
cd linux
make odroidgoa_defconfig
make

Once the kernel build is done, you should have an Image and the following dtb files. These will go to the /boot partition:

• arch/arm64/boot/Image

ls arch/arm64/boot/Image

• arch/arm64/boot/dts/rockchip/rk3326-odroidgo2-linux.dtb
• arch/arm64/boot/dts/rockchip/rk3326-odroidgo2-linux-v11.dtb
• arch/arm64/boot/dts/rockchip/rk3326-odroidgo3-linux.dtb

ls arch/arm64/boot/dts/rockchip/rk3326-odroidgo*.dtb

New kernel driver modules will need to be copied to the EXT4 partition:

sudo make modules_install ARCH=arm64 INSTALL_MOD_PATH=./<ext4 partition location> && sync

Make sure to install the compatible libmali video drivers to the EXT4 partition:

cd video_drivers
7z e rk3326_r13p0_gbm_with_vulkan_and_cl.7z
sudo cp libmali.so_rk3326_gbm_arm64_r13p0_with_vulkan_and_cl  ./<ext4 partition location>/usr/local/lib/aarch64-linux-gnu/libmali-bifrost-g31-rxp0-gbm.so
sudo cp libmali.so_rk3326_gbm_arm32_r13p0_with_vulkan_and_cl  ./<ext4 partition location>/usr/local/lib/arm-linux-gnueabihf/libmali-bifrost-g31-rxp0-gbm.so
