I am using MPC8260 in Configuration Master in 2 boards. At power-up MPC executes from flash but crashes after about (0.5 sec). It is also observed that if the board is powered-up for a few minutes then the MPC works fine. It seemed that when the system is heated a little bit it works fine. I have two identical boards. One of them is working perfectly fine and the other one is not.
Please I need suggestions and possible reasons of this behaviour.
Thanks in advance.
