Hi Peter,
Yes you need to enable UARTLITE as the console in the kernel
configuration.
You have the command line syntax, ttyUL0, correct.
They have now changed the UART 16550 to be a free core in the EDK, not
sure which version of the EDK that happened.
Thanks,
John

Do you have console on uartlite (CONFIG_SERIAL_UARTLITE_CONSOLE)
enabled?
