Linux Kernel

Environment Preparation

Ensure your system has the following dependencies installed:

sudo apt update
sudo apt install -y build-essential libncurses-dev bison flex libssl-dev libelf-dev bc dwarves debhelper

Source Code Download

First, clone the source code from your K1Pro kernel repository:

git clone --depth=1 https://github.com/bit-brick/k1pro-linux-kernel-6.1.git -b main k1pro-kernel
cd k1pro-kernel

Kernel Configuration

Generate .config file with default configuration:

make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- rockchip_defconfig

For custom configuration:

make ARCH=arm64 menuconfig

Kernel Compilation

Using external cross-compiler (if installed):

export CROSS_COMPILE=aarch64-linux-gnu-
export ARCH=arm64
make -j$(nproc) Image modules dtbs

Package as DEB

Create necessary directory structure:

mkdir -p package/DEBIAN package/boot package/lib/modules

Create package/DEBIAN/control file with the following content:

Package: linux-image-k1pro
Version: 1.0
Section: kernel
Priority: optional
Architecture: arm64
Maintainer: Your Name <your@email.com>
Description: Linux kernel for K1Pro

Process compiled kernel files to corresponding folders:

cp arch/arm64/boot/Image package/boot/
mkdir -p package/boot/dtbs
cp arch/arm64/boot/dts/rockchip/*.dtb package/boot/dtbs/
make modules_install INSTALL_MOD_PATH=package

Generate Debian package:

dpkg-deb --build package linux-image-k1pro_1.0_arm64.deb

Install Kernel Package

Install on K1Pro system:

sudo dpkg -i linux-image-k1pro_1.0_arm64.deb

Reboot and Test

After installation, restart the device:

sudo reboot

And verify the new kernel is loaded using:

uname -a
