Hi to all,
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.
Any idea?
The output I get is:
U-Boot 1.0.0 (Jun 30 2004 - 20:20:47)
