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
