CCS/TM4C123GH6PM: CCS/TM4C123GH6PM do not break on the main when debugging is started

Tool/software: Code Composer Studio

Is there any way to turn off the automatic break on debug startup feature?

I have looked over the debugger options, but I have not been able to find such an option. Please let me know if I missed something.

    Hello,

    Note that after a program is loaded, the debugger set the program counter to the entry point. If the auto-run feature is enabled, it will run to the label specified. By default, the auto-run feature is enabled and the label specified is' main'. This is why CCS auto-runs to 'main' on program load and then stays there. If auto-run is disabled completely, then the program will be halted at the entry-point after program load (usually 'c_int00' in most cases). If you wish to have it auto-run without stopping, make sure auto-run is enabled but have a label that is unreachable or the exit point of the application. This will just have the program run to completion (or run endlessly if it does not self-terminate)

    Thanks

    Many thanks for your answer!

    I have added a main_exit label after my main loop, and changed the main to main_exit.
    But now it stops at the c_int00. Maybe the compiler optimized out my label?

    I have set my FaultISR as a label to break.

    Perhaps. Try using: C$$EXIT

    That label should represent the exit point

    C$$EXIT as a label works like a charm!

    Thanks again for the great and quick support!
