Build Linux Kernel for AXON (RK3588)

This guide explains how to build the Linux kernel for the AXON board (RK3588), adapted from Vicharak’s Vaaman kernel documentation.

:toolbox: System Requirements

Recommended OS:

  • Ubuntu 20.04+ or Debian 11+

Install dependencies:

sudo apt-get update

sudo apt-get install build-essential python3 python-is-python3 libssl-dev \
git-core gcc-arm-linux-gnueabihf u-boot-tools device-tree-compiler \
gcc-aarch64-linux-gnu mtools parted pv bc bison flex gawk

Clone the Vicharak kernel repository:

git clone https://github.com/vicharak-in/rockchip-linux-kernel -b master
cd rockchip-linux-kernel

:gear: Configure Environment

Set cross compiler:

export CROSS_COMPILE=aarch64-linux-gnu-

:jigsaw: Load Default Config

make O=out ARCH=arm64 rockchip_linux_defconfig

:wrench: Apply AXON Device Configuration

Replace Vaaman config with AXON config:

cat arch/arm64/configs/rk3588_axon.config >> out/.config

:building_construction: Build Kernel

make O=out ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc --all)

:package: Output Files

After successful build:

  • Kernel Image:

  • out/arch/arm64/boot/Image

  • Device Tree:

  • out/arch/arm64/boot/dts/rockchip/rk3588-axon-linux.dtb

:books: Build Kernel Modules

make O=out ARCH=arm64 modules_install INSTALL_MOD_DIR=out/modules -j$(nproc --all)

Modules will be available in:

out/modules/lib/

Flash Kernel to Device

First back up the kernel with different name.
Check which kernel you are using by running below command.

uname -r

e.g. : 6.1.75-axon
Then. Go to device /boot paritition, and run below command.

sudo mv Image-6.1.75-axon bak-Image-6.1.75-axon

Now, Copy kernel and dtb files to board using ssh

scp out/arch/arm64/boot/Image <user>@<device-ip>:~/
scp out/arch/arm64/boot/dts/rockchip/rk3588-axon-linux.dtb <user>@<device-ip>:~/
scp -vr out/arch/arm64/boot/dts/rockchip/overlays <user>@<device-ip>:~/
scp out/modules_rk3588_axon.tar.gz <user>@<device-ip>:~/

sudo cp Image /boot/Image-6.1.75-axon
sudo cp rk3588-axon-linux.dtb /boot/rk3588-axon-linux-6.1.75-axon.dtb
sudo cp -r overlays /boot/overlays-$(uname -r)/

In order to apply new kernel, Restart the system.

sudo reboot
