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

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

$ source setenv.sh

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

Debian packages are in 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. Edge

The folder location is build/images/debs/1.0.11/Edge, and you'll need 3 packages: dtb package, image package and header package.

• DTB - linux-dtb-rockchip_4.4_1.0.11_arm64.deb
• Image - linux-image-rockchip_4.4_1.0.11_arm64.deb
• Header - linux-headers-rockchip_4.4_1.0.11_arm64.deb
