maybe problem is with I/O ports (failed instruction was ioread8) because
on one board I/O ports are not assigned, but on MPC8323E they are
invalid assigned.
I have no idea how to solve my problem, thanks for any help. What should
I try to do?
Best regards, Gregory Jakubowski
ps. sorry for my poor english
