Hi Leo,
Have you tried the baud rate of 921600?
Thanks, Amit. Yeah, 921600 can work well, this UART port is used by firmware but no kernel console.
Thanks, Leo Yan

Hi all,
I'm working one MediaTek X20 96boards, and install one Mezzanine board on it so can try to see if UART can work well or not.
After tried to switch Mezzanine's Jumpers in J1 to UART0, so I can see it can print out some logs; but later images print out log but totally cannot be unrecognized, please see below log info.
Tried to change baudrate from 115200 to 38400, but it's no lucky. So the unrecognized char issue is not caused by baudrate. Before I look into detailed kernel configuration, I'd like check if any guy has fixed this issue, could you point out what's wrong for this?
Thanks in advance. Leo Yan
