F28027 Breakpoints in ISR

Hi,

I am using F28027 piccolo.

I placed the EPWM ISR in the RAM by using Memcpy and #Pragma statement. The routine is properly placed in RAM (0x08000), but I have a hard time to set breakpoints. If I set them in the c listing, the debugger won't stop.

If I set them in Disassembly listing (and enabling global breakpoints), debugger will stop, if I place them

at specific stops. Often I would get  Error -1066 @ 0x800B, saying that the debugger was not able to remove the breakpoint.

Am I missing symbols ? I am using default settings in project setting, except for a redirection of Start label ( code_start instead of c_int00)

Should I use special debugger settings for the section mcopied to RAM during startup (before main {})   ??

Appreciate very much your help on this CCS 5.4 issue,

Regards
