I want to know the sequence of steps involved (if any), required to Debug a WatchDog Reset on a phone having ARM9. With/without it, a detailed explanation of the process like the registers that I 've to watch and TCBs that I need to look out for etc. would be really great and helpful.
Also, if somebody can shed some light on any ARM Document which details this fact would be really great.

    WatchDog functionality is part of the SoC not the uC...
    Generally, the WatchDog registers are very few and
    simple to use. You can not debug it as a normal step,
    because it resets the uC...

    Yes, I'm aware of the fact that a WatchDog Reset cannot be debugged using normal stepping. Hence, I require the procedure to Debug WatchDog Crashes.
