We are experiencing this issue with Atmel SAMA5D3 processor during boot-up.
There is a processor hang, when we do Power-On and Power-Off continuously.
The way to recover is to cut Vddbu.
Anyone has a solution to this problem?

Hello everybody,

do you have any news about this problem? We noticed this problem on SAMA5D34. Same behavior as you described. Board stays in reset state during startup and to unlock it, is needed to remove backup battery and turn off and on power supply. Thank you.
