ROCK Pi S > Development > Build vendor kernel(Rockchip 4.4)
The vendor kernel is based on the Rockchip 4.4 kernel with hardware support for ROCK Pi S. Below is how to build it on a X86 Linux host PC.
Contents
Get the kernel source
radxa@x86_64:~$ git clone -b stable-4.4-rockpis https://github.com/radxa/kernel.git radxa@x86_64:~$ cd kernel
Install toolchain from Linaro
radxa@x86_64:~/kernel$ wget https://releases.linaro.org/components/toolchain/binaries/7.3-2018.05/aarch64-linux-gnu/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz radxa@x86_64:~/kernel$ sudo tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz -C /usr/local/
Set environment variables
radxa@x86_64:~/kernel$ export ARCH=arm64 radxa@x86_64:~/kernel$ export CROSS_COMPILE=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-
Build kernel
radxa@x86_64:~/kernel$ make rk3308_linux_defconfig
If you need to build kernel modules that are not in the default config, you can select it in menu config
radxa@x86_64:~/kernel$ make menuconfig #(optional)
Now build it
radxa@x86_64:~/kernel$ make -j8
The built targets we care about are arch/arm64/boot/Image, dtb file arch/arm64/boot/dts/rockchip/rk3308-rock-pi-s.dtb, dtbo files arch/arm64/boot/dts/rockchip/overlay/*.dtbo.
Build kernel deb package
The kernel package build can pack the kernel, device tree, modules and firmware into Debian packages, which makes it easier to install on the ROCK Pi S.
Setup the version number, make sure the format is right.
radxa@x86_64:~/kernel$ export build_id="999" # make sure it's big enough so that our kernel is the newest.
radxa@x86_64:~/kernel$ export kgid="g$(git rev-parse --short HEAD)"
radxa@x86_64:~/kernel$ export lv="-${build_id}-rockchip"
radxa@x86_64:~/kernel$ export kv=$(make kernelversion)
radxa@x86_64:~/kernel$ export debv="$kv$lv"
radxa@x86_64:~/kernel$ make bindeb-pkg -j8 LOCALVERSION=$lv-$kgid KDEB_PKGVERSION=$debv
The generated packages are(the kernel revision name maybe different):
radxa@x86_64:~/kernel$ ls ../*.deb ../linux-firmware-image-4.4.143-999-rockchip-g9512142776c9_4.4.143-999-rockchip_arm64.deb ../linux-headers-4.4.143-999-rockchip-g9512142776c9_4.4.143-999-rockchip_arm64.deb ../linux-image-4.4.143-999-rockchip-g9512142776c9_4.4.143-999-rockchip_arm64.deb ../linux-image-4.4.143-999-rockchip-g9512142776c9-dbg_4.4.143-999-rockchip_arm64.deb ../linux-libc-dev_4.4.143-999-rockchip_arm64.deb
Copy linux-firmware-image-4.4.143-999-rockchip-*_arm64.deb, linux-headers-4.4.143-999-rockchip-*_arm64.deb and linux-image-4.4.143-999-rockchip-*_arm64.deb to your ROCK Pi S.
Install packages on ROCK Pi S in order
root@rockpis:~# dpkg -i linux-headers-4.4.143-999-rockchip-*_arm64.deb root@rockpis:~# dpkg -i linux-image-4.4.143-999-rockchip-*_arm64.deb root@rockpis:~# dpkg -i linux-firmware-image-4.4.143-999-*_arm64.deb
Reboot ROCK Pi S. You will have the new kernel booting.
