Hi,

I have the watchdog timer enabled in the AT91SAM9260 processor. It's configured to generate a processor reset and peripheral reset after a watchdog timeout occurs. When I stop punching the watchdog, it appears to start the reset after the timeout period (8 seconds) but this never completes. My whole board just locks up. If I configure the watchdog to generate an interrupt instead of a reset and then do a software reset in the interrupt handler, it resets correctly.

My question is, does anyone know why the AT91SAM9260 will not boot up after a watchdog reset. Are there other settings in the AT91SAM920 that I need to configure which may have some effect?

Thanks for your help.
