Hi all,
On my board (at91sam9263ek) I have enabled the watchdog.
It will reset the processor after about 16 seconds.
It looks like it is working but if I'm writing a large file into nand it 
seems that the watchdog is not reset and finally my processor resets.
I've patched it, but I'm not sure if it is the right way to do it this 
way...
