[En-Nut-Discussion] Watchdog AT91SAM7X

[Ulrich Prinz]

Hi Jason!

Im am new to this list, so I might have missed something. But I feel 
like it's difficult to help you without seeing any line of code.

For the Watchdog there are only two pieces of code needed. One routine 
setting it up to the desired timeout value and enabling it.
Second routine is only a shortcut to retrigger it right in time for the 
overlaying software. Call it a macro (like WDT in AVR code).

Often I see code that disables a watchdog also assembled as a function. 
For my feeling that is very destructive as this anables a crashed 
software to execute this function on error what is exactly what noone 
will ever like to see. But it could exist in a macro then it is only 
compiled into the code if one really needs and calls it.

Regards,
Ulrich
