CCS/AM3352: Breakpoint with "Update View" action slows the program

Hi Andy,

I declared a global variable in ISR and set a bp on that variable in order to observe how many times is this ISR triggered dynamically.

As you suspected, setting a breakpoint there would be very intrusive. The target would be halted each time to update the views. This would drastically impact your real-time performance on the target.

Is debug access port the only way for real-time debug?

Yes, through the DAP you can accomplish real-time (non-intrusive) memory access.

I'm 100% sure, but I believe on the ARM, the DAP is used under the hood by the debugger when making memory accesses. So you should just be able to add that global variable in the expressions view and enable continuous refresh to see the value increment. I know this is supported on Cortex-M, but I believe it also applies to Cortex-A

Thanks
