Mpc5200B network communication failure

we have some problems with the Mpc5200B network communication.

an aplication which periodically sends huge data over ftp (64 MB Files)

still hangs every 10 - 30 times and the CPU seems to be dead.

If i read in this case some registers using a Jtag Debugger , the CPU Core (603)registers are readable, but all registers adressed over MBAR are showing a 0x0.

The Mbar Register self is set by the bootloader to 0x0000f000 and

this value is still set. our suspicion is it could be a problem with the XLB Bus.


The same Application on a mpc5200 still works!

I think also a silicon Bug is possible!?


Did anyone have an idea or tips to localize or solve the problem?
