    Depends on your definition of simple. From what I've seen, U-Boot's console is hard-coded in the source. You need to change the source and rebuild U-Boot. Runtime setting does not seem possible. Looks like the default UART is defined in the your board's header in include/configs.

    made it and as for other users:

    modify the UART2 base to UART0 in da850.h config

    mark any other UART2 initialize code (UBL already made it, for UART0, there are bugs in UBL codes, must change before we could use UART0)

    that's all, I think that's simple
