Another method I have been using to implement a watchdog is routing e.g., a DMA timer output to the reset line
and use that as a watchdog.

Yes, to get the code in devWatchDoc.c to work the bootloader code must be modified.  The source for the existing code is not available.
The best suggestion I can think of would be to start from some existing open source bootloader code such as "My Right Boot": uClinux -- Embedded Linux/Microcontroller Project -- ColdFire: Boot Loaders

I am grateful of your immediate reply. According to your advices, is it means that the only way to make watchdog timer work is to modify the bootloader in uC5282. But as I know, the bootloader is not a open source,   can you  help me get the source code of the bootloader, or some methods to obtain it?
 
         If I can’t start the watchdog timer, then the driver devWatchDog.c also cannot work, right?
 
       Expect for your reply ! Thank you.
