Build Linux Kernel

This documentation will introduce how to build Linux kernel from source code.

We suggest to use Fenix to build Linux, just a few simple commands needed. Please refer to Build Ubuntu/Debian Images to setup the development environment.

Setup Environment

You need to choose the BOARD, e.g. VIM3, U-Boot version, Linux version, system version, etc.

$ source

At current stage, two version of Linux kernel supported:

  • SoC vendor Linux version 4.9, version is old but has best support
  • Mainline Linux version, latest version but some functions may not work

You need to choose the correct version due to your requirement.

Change the kernel config [Optional]

If you want to change the default kernel configuration you can follow these steps.

make kernel-config
make kernel-saveconfig


Simple commands to build Linux Debian package.

$ make kernel
$ make kernel-deb

You can find the Debian packages in folder build/images/debs/{VERSION}/{BOARD}.

VERSION : Means to Fenix version, e.g. 1.0.7
BOARD : Means to Khadas board, e.g. VIM3

So the folder may be build/images/debs/1.0.7/VIM3, there are three packages we need: dtb package, image package and header package.

  • 4.9
    • DTB - linux-dtb-amlogic-4.9_1.0.7_arm64.deb
    • IMAGE - linux-image-amlogic-4.9_1.0.7_arm64.deb
    • Header - linux-headers-amlogic-4.9_1.0.7_arm64.deb
  • Mainline
    • DTB - linux-dtb-amlogic-mainline_1.0.7_arm64.deb
    • IMAGE - linux-image-amlogic-mainline_1.0.7_arm64.deb
    • Header - linux-headers-amlogic-mainline_1.0.7_arm64.deb
