    Hi Lisa,
    By default, the debugger automatically sets some breakpoints during debug. One is at 'main' and another is at the exit point of the program. After the program is loaded, it will try to set a breakpoint at 'main' and auto-run to it. But if you do not have a 'main' in your application, then it will not be able to set the breakpoint there and the auto-run to main would fail and instead leave the program running. This behavior can be disabled in the debugger properties:

    Thanks

    Hi Ki,

    I have a "main" in my program. But it still didn't run to main. I also disable autorun but it still didn't run to main. I clean whole breakpoint in project but still can't run to main. Could you please tell me is there other thing need to set ?  thanks

    Hi Lisa,
    If you have a main in your program but the program never reaches it, then there must be some issue with the program where it hits some exception before it reaches main. When you halt the target, where is it halted in the program?

    Thanks

    hi Ki,

    sorry for late reply. When I halt the target, it stop in a loop which include in main.

    Try disabling your auto-run setting (Tools -> Debugger Options):

    hi Ki,

    Hi Lisa,
    Disabling the option prevented the debugger from autorunning. So it is expected to stop at c_int00 first since that is the code entry point.

    As for why you cannot run to main, that is something you will need to debug as it is not a tools specific issue. Sounds like your application is hitting some exception or something that is preventing it from reaching main. Where does your code get stuck?

    Thanks
