How To Upgrade The u-boot

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

  • Set the Fenix environment
$ source source env/setenv.sh
  • Build the u-boot debian package
$ make uboot
$ make uboot-deb

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

FENIX-VERSION: means the Fenix SDK version, e.g. 0.8.3
BOARD: means the khadas board you choosed, e.e. VIM3

So the package directory maybe: build/images/debs/0.8.3/VIM3, and the debian package maybe: linux-u-boot-vim3-vendor_0.8.3-2015.01_arm64.deb.

  • Upgrade the u-boot

Copy the u-boot debian package to the board and install it.

$ sudo dpkg -i linux-u-boot-vim3-vendor_0.8.3-2015.01_arm64.deb
$ sync
$ sudo reboot
