CCS/MSP430FR2311: JTAG debugging code always stops on "MSP430 - Debug Call Stack"

Andrew5821

Tool/software: Code Composer Studio

I have no breakpoints in my code, but my code always stops at a certain line, like a breakpoint would, and all it says there is "MSP430 - DBUG Call Stack". If I change compiler optimizations so I can actually view it, the code doesn't stop there anymore. Also, I found if I add a simple delay the problem goes away as well so it is very specific. Also, the code never runs properly even after I stop the debugger, but if I power cycle the device, the programmed code executes just fine.

Hi Andrew,

I've seen similar issues reported with MSP430 and the issue is usually related to some device configuration and not a tools issue. For example:

Try running at 8MHz and see if that helps.

Thanks

Is this only related to when running the JTAG debugger at 16MHz? Is running my code stand-alone OK?

I believe it is an issue with the device configuration (running at 16MHz) and not with your code (though this is a bit beyond my area of expertise). Try running at 8MHz and see if it helps. If it does, then it would confirm the same issue and I can let the device experts know.

I can try that, but pretty much making any change to the code makes it go away. For example, I added a delay(1) at the start of main and that made it go away.

Any code change? Instead of a delay loop, even something simple like declaring a variable will also make the issue go away?
