Build, pack and install Radxa Zero Kernel

Below we will show you how to build, pack, and install Radxa Zero kernel with a Ubuntu 20.04 HOST PC.

Hardware Required

  • Radxa Zero
  • USB A to C cable
  • A PC/laptop running Ubuntu 18.04 or higher

Set up build environment

$ sudo apt update 
$ sudo apt install gcc-aarch64-linux-gnu device-tree-compiler libncurses5 libncurses5-dev bc python dosfstools flex build-essential libssl-dev mtools bison flex bison git wget
$ wget https://developer.arm.com/-/media/Files/downloads/gnu-a/10.3-2021.07/binrel/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf.tar.xz
$ sudo tar xvf gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf.tar.xz -C /opt

Get kernel source code

$ mkdir ~/radxa-zero-sdk
$ cd ~/radxa-zero-sdk
$ git clone https://github.com/radxa/kernel.git -b linux-5.10.y-radxa-zero

Build kernel

$ cd kernel
$ export ARCH=arm64
$ export CROSS_COMPILE=/opt/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf/bin/aarch64-none-elf-
$ make radxa_zero_defconfig
$ make -j8
$ ls arch/arm64/boot/Image
arch/arm64/boot/Image                                                          # this is the kernel image
$ ls arch/arm64/boot/dts/amlogic/meson-g12a-radxa-zero.dtb
arch/arm64/boot/dts/amlogic/meson-g12a-radxa-zero.dtb                          # this is the device tree blob

Pack Kernel

$ export ARCH=arm64
$ export CROSS_COMPILE=/opt/gcc-arm-10.3-2021.07-x86_64-aarch64-none-elf/bin/aarch64-none-elf-
$ make radxa_zero_defconfig
$ export build_id="999"                                                        # make sure it's big enough so that our kernel is newer than package from apt repository
$ export lv="-$build_id-amlogic"
$ export kv=$(make kernelversion)
$ export debv="$kv$lv"
$ make bindeb-pkg -j8 LOCALVERSION=$lv KDEB_PKGVERSION=$debv

The generated packages are (the kernel revision name might be different, in our case it is 5.10.69): 

$ ls  ../*.deb
../linux-headers-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb
../linux-libc-dev_5.10.69-999-amlogic_arm64.deb
../linux-image-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb

Install Kernel on Radxa Zero

Copy linux-headers-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb and linux-image-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb to your Radxa Zero. Then install with following commands: 

rock@zero:~$ sudo dpkg -i linux-headers-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb
rock@zero:~$ sudo dpkg -i linux-image-5.10.69-999-amlogic_5.10.69-999-amlogic_arm64.deb

Reboot into your new kernel.
