Hi Ben, Many thanks for your reply, then I suppose the best option is the PCU UART I'll continue with that
Thanks and best regards Adrián -----Mensaje original----- De: Ben Gardner [mailto:[email protected]] Enviado el: 19 April 2016 17:26 Para: Adrian Perez Resa CC: [email protected] Asunto: Re: [coreboot] Using High Speed UART1 as Serial port on CoreBoot (MinnowBoard) Hi Adrian, You are better off hooking up to the "Serial Console" port and using that. http://wiki.minnowboard.org/MinnowBoard_MAX If you really want to use one of the HS UARTs, then you have a bit of work to do. See src/drivers/uart/uart8250mem.c and note the use of CONFIG_DRIVERS_UART_8250MEM_32. You'd need to implement something similar to src/soc/intel/skylake/romstage/uart.c, but for the E3800. Not worth it, in my opinion, as the PCU UART works just fine.
