After some days working ok with my MPC8272ADS board, now it keeps rebooting all the time with a Program Check report. It has arrived after a hang.
I have been checking the output as this is all the information i have at the moment. I have realized that clock reporting is incoherent (the true one is cpu_clk=400Mhz), so i wonder if it has any relation.
Looks like broken hardware to me. ESD?
Best regards,

I get the same thing when I mount a new MPC8272 part labled: MPC8272ZQTIEA 400/200/100 MHZ
I wonder if the PVR value has changed for newer chips.

My old part gives:
