Build problem about debos

  • I want to use i2c0 on Rock 3a, so build own image with radxa-debos.

  • environment: Ubuntu 20.04

  • according to,step by step, but fail in first step:

## cmd
sudo apt install -y git user-mode-linux libslirp-helper

## report error:
Package user-mode-linux is not available
Package docker-ce is not available
  • so, how to do if i want to use ubuntu 20.4?


emmmm, I make a mistake…
because of dtb, so just modify boot/dtbs/4.19.193-44-rockchip-g5a07852a55cf/rockchip/rk3568-rock-3-a.dtb
