I have what I hope will be a very simple problem to solve:

Here's the situation: we have a custom board based heavily on the Lite5200 board (Icecube) from Freescale. We have u-boot running on it in the default configuration where the console is set up on PSC1. We need to switch the console to the second serial port.

If I change the console in cpu/mpc5xxx/serial.c to PSC2 by changing the configuration define CONFIG_PSC_CONSOLE in include/configs/IceCube.h to the value "2" instead of the default "1", the resulting u-boot image will not work.

When I say "will not work", I mean that there is no output at any baud rate on any serial port, and the machine appears to be hung.

If I leave the console at PSC1, and then switch the console to PSC2/ttyS1 when I boot linux, the console switches to PSC2 and works just fine.

Is there some other configuration step I need to go through to make this work?

thanks and best regards,
