Dear All,

I am facing a very strange problem in STM32F103RET6. It is showing completely random behavior on Power Reset. On some PCBs it RESET on every power Reset, while both PCBs have same hardware(means identical hardware , components etc). In my design I am using two STM32s(on each side of PCB). One is working perfectly in all boards.

The boards which are showing problem require to put on zero power for few minutes.
