Watchdog timeout prevents erasing flash

I loaded a version of software for our 52258 based system that had a 2 second watchdog timeout.  Now I can't erase the flash to download a new version from codewarrior because it times out in the middle of the erase and resets.  How do I prevent this from happening?

Thats odd, because I thoght that the IDE resets the mcu, loads a program into ram using the BDM  and uses that to do stuff.

Explain how you are doing this...

That is what I thought too.  I start codwarrior, the pod is attached to my system and I go to the tools menu as usual.

 

I load the settings and try to erase flash.  It downloads the flash program, says running and about 2 seconds later the board resets (I hear the power relay click) and my initialize led flashes and it goes to system clock checking and stays there forever.

 

If I hit cancel and then erase again it says erasing, resets again in about 2 seconds and stays at erasing forever.

 

This can be repeated for 4 or 5 times and then codewarrior locks up and I have to kill it and restart.

 

I thought with the debug pod on all of the stuff like the watch was disabled.

You might try PE Support, I have had excellent results with them.

I unplugged and replaced the pod and re-started codewarrior (for the fifth time) and it just started working.

I forgot to add I am using the P&E USB debugging pod and version 7.2.2 Codewarrior.
