According to the FEX file, your board uses different debugging UART than Lichee Pi Zero. (Lichee Pi Zero uses UART0 @ PB, but your board uses UART2 @ PB) Maybe you should try to alter UART-initialization-related code. > > Digging through the commit messages for v3s mainline u-boot support I've > noticed that SPL is disabled.
