Slowly I am managing to get some first debugging steps working with AVR32 studio. However often the debugger will step into some code where it says that it doesn't have any source code for and it can't be stopped - when anything is attempted it gives a message "Selected Target is busy".
If I attempt to terminate the debug session it doesn't respond for a few minutes and maybe then gives an error that it couldn't terminate.
Generally I find that it is quickest to close AVR32 studio and start it again, after which debugging can be attempted again.
Does anyone know why it hangs when stepping into code without source and how the debugger can be terminated more gracefully?
