    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.

Build kernel on linux PC

Requirement

   $ sudo apt-get install libncurses-dev flex bison libssl-dev git

Get the mainline kernel source

   $ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
   $ cd linux

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 defconfig
   $ 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.

Copy files

   $ sudo cp Image rk3399-rock-pi-4.dtb /boot/

Configure

   $ sudo vim /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 earlyprintk console=ttyS2,1500000n8 rw root=PARTUUID=b921b045-1d rootfstype=ext4 init=/sbin/init rootwait

Reboot you will have the new kernel booting.
