CCS/TMS320F280049: Breakpoint in RAM functions

Tool/software: Code Composer Studio

Hello,

Using CCS9.3, I was trying to write an SPI interface in interrupt mode. The target setup is FLASH and I added __attribute__((ramfunc)) before interrupt routine to speed up the performance.

I noticed, although the program is working properly and interrupt is services correctly, the breakpoint in the interrupt service routine never hits unless I remove the ramfunc directive and tun it from flash memory.

Is there any setting that I missed to set a breakpoint in ramfunctions?

MHG,

Please have a look at this FAQ, I believe it explains the behavior you are seeing.

AartiG,

Thank you for the link to FAQ.

When I click on the left bar of a source code, I set a hardware breakpoint on that line. If this is true, then the FAQ article does not apply to my case, otherwise case is resolved.

Ok, got it, CCS uses Hardware breakpoints for Flash locations and software breakpoint for RAM locations.
