    Hi Walter,

         It is possible that the program you just flashed is causing this. Erase entire flash using LM Flash Programmer, and see if you get the same problem with known working example programs. If you encounter some error erasing flash using LM Flash Programmer, your debug port, might have been locked out, by that program you flashed. If this happened, try the LM Flash Programmer Debug Port Unlock Utility.

    Walter, 

    It sounds like you never reach main() ?

    The debugger, by default, will try to run to main() after flashing the code.  But if you're taking an exception before getting there the debugger may not stop.  

    Please try the following.  Flash the code, then do a system reset by hitting the drop down arrow on this icon:

    You should find yourself at _c_int00().  Single step until you either get to main() or branch to 0xffff.fffe.

    Have you changed your linker script at all?  Or switched from one device to another such that your code doesn't really fit in memory?

    Hi Markel,

    thanks for answer! but the debug Port is not locked.

    If i import the source files in an new project, than all is fine.

    best regards Walter

    Hello Miles,

    thank you! I "lost" my linker script file.

    Funny that the debugger dont knock me on the fingers before i start with debugging.

    best regards Walter
