How To Upgrade The kernel

We use Fenix to build Ubuntu/Debian images. You can also use it to build the kernel debian package.

  • Set the Fenix environment
$ source source env/
  • 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
  • Build the kernel debian package
$ make kernel
$ make kernel-deb

The you will find the kernel debian package in directory build/images/debs/FENIX-VERSION.

FENIX-VERSION: means the Fenix SDK version, e.g. 0.8.3

So the package directory maybe: build/images/debs/0.8.3, and the debian package maybe: linux-image-amlogic-mainline_0.8.3_arm64.deb.

DTB debian package: linux-dtb-*.deb
Kernel debian package: linux-image-*.deb
Header debian package: linux-headers-*.deb

  • Upgrade the kernel & dtb

Copy the kernel & dtb debian packages to the board and install it.

$ sudo dpkg -i linux-dtb-*.deb 
$ sudo dpkg -i linux-image-*.deb
$ sync
$ sudo reboot
