TMS320F28335: Breakpoint only stops once in for loop when debuging with CCStudio 12.2

Hello,

The first thing to try is to disable any optimization and see if the issue still exists. If it does, please provide a small reproducible test case. 

Thanks

Hello,

I have optimization set to off, and the issue persists. I think the problem is related to a limitation to only one breakpoint at a time. If I switch the breakpoint from line 8 to line 9 of the example, I observe how 'provaLoop' is increasing from 0 to 50. However, if I set the breakpoint to either line 8 or line 9 and repeatedly press the Resume button, the code does not run, and I do not see the 'provaLoop' variable increase.

I have attached the example code:

	int provaLoop = 0, provaLoop2 = 0;
	for (; ;)
	{
		AFQevo_StateMachine(&AFQe, &FFTe);

		for (provaLoop=0; provaLoop<=50; provaLoop++)
		{
		    provaLoop2 = 1;
		    provaLoop2 = 2;
		}
		provaLoop = provaLoop2;
	}

Yours,

If you code is in flash, then hardware breakpoints are used. Many older F28x devices only have 2 hardware breakpoints available. Often times the debugger will use breakpoints for other things, further limiting the number of breakpoint resources available for you to use.

When you are out of hardware breakpoint resources, the debugger usually reports it:

Do you get any messages from the debugger when it can't run?

Thanks

None of these messages appear when I use breakpoints. I also tried unchecking the 'Remove CIO function use' (‘Halt at program exit for TI compilers’ was already unchecked), but the problems persisted.

Please provide a small reproducible test case. This includes a complete project, not just example code. That way I can see all your project settings.

how can I send you the project?

You can zip up the project folder and attach it to this thread. If you wish to share privately, you can send via private E2E message to me.
