Hey guys, I am trying to use the Computer Operating Properly (COP) Module and am having some trouble. My problem is that the DSP will not reset when the timer expires. I just gets stuck. Does anybody know if I missed any configuration parameters Thanks In Advance Victor

Victor, COP will not work in debug mode. If you are using CodeWarrior debugger, it will disable COP. The only way to use COP is to run your application in stand-along mode (without debugger attached). Leonard N.

Hmmm. I believe that I have noticed this. What I have been doing is programming the flash with a small test program and then I would disconnect the programming cable and then hit the rest button. My program will get through the first few lines which have the watchdog service routines and then I purpousely delay the next watchdog routine so that it times out and what I believe is happening is that I seems to begin to reset but where it goes from there is beyond me. It just seems to get stuck and doesn't seem to jump back into main(). My best guess at this moment is that it is jumping into some unhandled reset vector but I am unable to verfiy this without the use of the debugger. Any suggestions. Victor void main (void) { WatchDog(); InitializeChip(); WatchDog(); while(1) { WatchDog(); ioctl(PortB, GPIO_SET, gpioPin(B, 0)); Delay(250); WatchDog(); ioctl(PortB, GPIO_CLEAR,gpioPin(B, 0)); Delay(250); WatchDog(); ioctl(PortB, GPIO_SET, gpioPin(B, 0)); Delay(250); WatchDog(); ioctl(PortB, GPIO_CLEAR,gpioPin(B, 0)); Delay(1000); <-------------------------------should and does expire cop timer here.
