Dear Michael, Yep didn’t got any prints. So tried a hack. a) Booted using uart 2 b) set the GPACON c) Copied the config from 0x12c20000 to 0x12c30000 d)tried to write a char 0x41 (A) on 0x12c20020 0x12c30020, I got output on UART2 but not on UART3. We would like to use both uarts. Have you used UART3, did the boot to UART3 worked for you ? So you see any problem with any of our steps listed in this / pref mail.
