We provide Fenix to build the Ubuntu OS images easily. You can follow the steps below:

Choose your board (e.g. VIM4), U-Boot version, Linux version, system version, etc.

$ source setenv.sh

$ make kernel-config
$ make kernel-saveconfig

Build the Linux Debian package.

$ make kernel
$ make kernel-deb

Debian packages are placed in the folder build/images/debs/{VERSION}/{BOARD}.

• VERSION : refers to the Fenix version, e.g. 1.0.11
• BOARD : refers to the Khadas SBC, e.g. VIM4

The folder location is build/images/debs/1.0.11/VIM4 where you'll need three packages: dtb package, image package and header package.

• linux-dtb-amlogic-5.4_1.0.7_arm64.deb - DTB
• linux-image-amlogic-5.4_1.0.7_arm64.deb - Linux kernel
• linux-headers-amlogic-5.4_1.0.7_arm64.deb - Linux headers
