Hi,
 
I have configurable options, stored in flash. It can be configured form web,
and after that I need to reset myself. On AVR it can be 
do with watchdog easily, but on SAM7X wd works in a stupid mode.  It can be
written only once, and Nut disable it at startup.
 
Can somebody suggest me a good solution for it? I mean don't disable wd at
startup, kick it periodically in a timer irq, and don't kick
if I need, or somthing like that. (The hw is ready, so I can't reset myself
with a GPIO, example)
 
 
Thanks,
Andras
