Debug labels for testing

Try this macro instead ...

#define DEBUGLABEL(name) asm(" .global TSTLBL_" #name "\n" \
                             "TSTLBL_" #name ":") 

The techniques used in this macro are explained in this wiki article.

Thanks and regards,

Hi George,

Thank you. Now the debug label is present in map file. When I tried to debug on CCS (set a break point just before the debug label and step in) , I am getting the error on debug label says "No source available for "TSTLBL_Switch_Start() at C:/Synergy\E2_BCS_SW\Boot\Boot_Code\CCStudio\Debug\Boot.out:{3} 0xbc8{4}"".  But this works in Disassembly mode. Do I need to change any build settings? 

Is there any way to attach the snapshots?

I think you can ignore this diagnostic.  I think CCS expects to find a function with this name in your system.  But there isn't one.  So it issues this diagnostic.  Are you seeing any other problems besides this diagnostic?

Thanks and regards,

Yes. I am not able to set breakpoint on this debug label to read/write local variables. In this example, I need to stop on debug label "File_Switch_Start" and modify the crcResult. When I set a breakpoint on this debug label and run, then I got the error says source code not found before hitting the break point.

/* Wait to complete the CRC verification process */
do
{
  crcResult =
  CRC_Process(CRC1);
} while (crcResult == CRC_ERR_BUSY);

DEBUGLABEL("File_Switch_Start");

/* Set Failure flag based on return value */
switch (crcResult)
{
   /* CRC Failure */
   case CRC_ERR_COMPARE:
   ....
   ...
}

I suspect CCS does not support what you are trying to do.  But, I am not sure.  So, I will move this thread to the CCS forum.

Thanks and regards,

Thank you.
