Linux on MPC5200 - LITE5200EVAL

[Peter Falk]

Had the same problem with garbage, apparently a rounding problem in the
baudrate calculation.
The above patch shows the changes suggested by someone on the net, can't
remember his name but it is on the patches page of sourceforge.net.
After application of this it worked fine.
One gotcha, hardware handshake off on your terminal software! U-Boot
wants it off, The motorola DBUG wants it on, this kept me busy for a
day.

Peter Falk

I followed these instructions and it all worked out fine (left out the
examples directory of U boot though) , but after the reboot in lowboot
jumper configuration, i only see garbage on my minicom screen. I can
figure out some characters that look familiar (like the countdown for
the autostart) so I assume it's working correctly but doesn't get
displayed right. I also can't interrupt the countdown so input doesn't
work. Already tried to change the 115200 8N1 settings of the
communications (but why would they change anyway..) and didn't help.

What could possibly be wrong ??

checked it and there's a resistor between 2-3 and not 1-3 so i guess
that's right.. (I have version 2.0 Lite)
