====== VIM1S Build Linux Kernel ======

We provided [[kg>fenix|Fenix]] for you to build the Ubuntu OS images easily. You can follow the steps bellow to build Linux Kernel.


===== Setup Environment =====

Choose your ''board'' (e.g. ''VIM1S''), ''U-Boot version'', ''Linux version'', ''system version'', etc.

```shell
$ source setenv.sh
```

===== Change the Kernel Config [Optional] =====


Follow these steps to change the default kernel configuration.

```shell
$ make kernel-config
$ make kernel-saveconfig
```

===== Build =====

Build the Linux Debian package.

```shell
$ 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. ''VIM1S''

The folder location is ''build/images/debs/1.0.11/VIM1S'', and you'll need 3 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
