CCS/CCSTUDIO-C2000: Code encounters break during debug mode and stops executing

Siva Mohan

Part Number: CCSTUDIO-C2000

Tool/software: Code Composer Studio

I am using CCS 9.0.1 to debug a project on TMS320F280049C control card - during debug mode, the code begins to execute and suddenly ends up at an unknown address and suspends debug operation with the following error message.

Break at address "0x3fb02a" with no debug information available, or outside of program code.

I tried using new workspace locations, different projects but the error seems to be persist. I also created a new configuration file and used it to load the .out program manually but the error does not go away. Please help in resolving this issue.

Regards
Siva

    Hi Siva,

    The error message itself is not really an "error" but simply a warning that there is no source code correlation at that program address. It looks like your program is hitting some exception or ending up at an unexpected location. The bigger question is why this is happening. It is unlikely that this is a tools issue, but more of an environment setup issue or issues with your program. You will have to do some debugging to see why. I assume the call stack is not showing anything useful. If you know roughly where the application runs into issues, you can try setting a breakpoint there and stepping after the breakpoint to see where exactly the application goes wrong.

    Thanks

    Hi Ki,

    Thanks for the suggestion. The bug has been fixed. It was due to lower than necessary current limit on C2000 power supply causing a voltage drop and power recycle during debug. I increased the current limit and the problem went away.

    Regards
