Edge2 Build Linux U-Boot

We provided Fenix for you to build the Ubuntu OS images easily. You can follow the steps bellow to build U-Boot.

Setup Environment

Choose your board (e.g. Edge2), U-Boot version, Linux version, system version, etc.

$ source setenv.sh

Choose the correct version for your requirements.

Build U-Boot with a single command:

$ make uboot

The binaries are located in U-Boot source code root directory. You'll need uboot.img and rk3588_spl_loader_vx.xx.xxx.bin.

uboot.img - U-Boot image.
rk3588_spl_loader_vx.xx.xxx.bin - SPL loader image, x.xx.xxx means version, e.g. 1.07.111
