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 # for packing on non Debian system you may need `DPKG_FLAGS=-d` to skip dependency check
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.
