Well, you have to unserstand *exactly* what the CPU and the board are
doing - the MPC5200 has multiplexed pins, and if you select one
function you lose a few others, so you must carefully check for
conflicts. Probably you will have to disable some other functions.
Also you have to usnerstand what the board is designed like - some
ports have specific and reserved functions.
Finally, there are such things like wrong baud rate on a serial port
which may make you think it's not working while you are just using bad
user mode settings.

Yes, it is. But you have to know what you are doing.
