Using Code Composer 4.2.4 ... how does one set a break that occurs when a global variable changes?

    Hi Clyde,

    what target are you using?  Some targets support different features.  Have you tried opening the breakpoint view ... View->Breakpoints.  Then the first icon from the left in the window that comes up (Breakpoints Window) is where you have an option to add a breakpoint or watchpoint as well.  If this is supported for your target, you will actually want a watchpoint.

    Please keep us informed and also look at these wikis of interest

    In case of c28x interest:

    http://processors.wiki.ti.com/index.php/Data_Breakpoint/Watchpoint

    For almost every target, what you can do is set a breakpoint/watchpoint that flips when a variable has a certain value.  For this see the below screenshot.

    Best Regards,
    Lisa
