We provide Fenix for you to build the Ubuntu OS images easily. You can follow the steps below to build Linux Kernel.

Configure the environment by choosing your board (e.g., Edge-2L), U-Boot version, Linux kernel version, system version, etc.

$ source setenv.sh

Select the options that match your requirements.

Follow these steps to change the default kernel configuration.

$ make kernel-config
$ make kernel-saveconfig

Build the Linux Debian package.

$ make kernel
$ make kernel-deb

The generated Debian packages are located in the folder build/images/debs/{VERSION}/{BOARD}/.

• VERSION : refers to the Fenix version, e.g. 1.1.1
• BOARD : refers to the Khadas SBC, e.g. Edge-2L

For example, the folder location would be build/images/debs/1.1.1/Edge-2L/, and you will need the following three packages: the DTB package, the image package, and the header package.

• DTB package - linux-dtb-rockchip-6.1_1.1.1_arm64.deb
• Image package - linux-image-rockchip-6.1_1.1.1_arm64.deb
• Header package - linux-headers-rockchip-6.1_1.1.1_arm64.deb

• Build U-Boot.
• Build Ubuntu.
• Upgrade Linux Kernel
