    ROCK Pi 4 >  Development >  Build mainline kernel(5.x)

ROCK Pi 4 is officially supported in mainline kernel since v5.1 thanks to developer Akash Gajjar from Mentor. Below is how to build it on a X86 Linux host PC and run on ROCK Pi 4.

Get the mainline kernel source

   wget https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/snapshot/linux-5.2-rc6.tar.gz
   tar -xvzf linux-5.2-rc6.tar.gz
   cd linux-5.1.15/

Install toolchain from Linaro

   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
   sudo tar xvf gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu.tar.xz  -C /usr/local/
   export ARCH=arm64
   export CROSS_COMPILE=/usr/local/gcc-linaro-7.3.1-2018.05-x86_64_aarch64-linux-gnu/bin/aarch64-linux-gnu-

Build kernel

   make menuconfig
    • In the menu-config TUI:
  • Navigate to Platform selection ---> Rockchip Platforms
  • Select Rockchip Platforms
   make -j6

copy arch/arm64/boot/Image and arch/arm64/boot/dts/rk3399-rock-pi-4.dtb to your ROCK Pi 4.

Install it on ROCK Pi 4.

   rockpi4# cp Image rk3399-rock-pi-4.dtb /boot/
   rockpi4#vi /boot/extlinux/extlinux.conf
    • Change the contents to:
  label kernel-mainline
  kernel /Image
  fdt /rk3399-rock-pi-4.dtb
  append earlycon=uart8250,mmio32,0xff1a0000 swiotlb=1 coherent_pool=1m earlypp

rintk console=ttyS2,1500000n8 rw root=PARTUUID=b921b045-1d rootfstype=ext4 init== /sbin/init rootwait

Reboot you will have the new kernel booting.
