CW 10.1 - How to break debugger when variable changes

ignisuti — Tue, 13 Dec 2011 03:17:45 GMT

I’m using the Multilink Universal debugger with a 6-wire BDM cable to debug a MCF51CN128 Coldfire MCU.

How can I get the debugger to 'break' on the line of code causing one of my variables to change values?

Hello

I am not an expert on MCF51CN128, but for other MCUs I used watchpoints for this purpose.

To set a watchpoint:

- In the Variable Windows display the variable you want to track

- Click right on the variable name and select watchpoint

- Adjust settings of the watchpoint to whatever you want to track.

- Click on OK.

Note that watchpoint may not be supported on all MCUs as it requires some HW resources to function properly.

But it might be worth a try.
