I have not tried it since I have had the download problem, but I will. > Does a manual 'Target'-'Reset' in > MSEide change the situation? No, I think because, if indeed the Target-Reset triggers a hardware reset, the processor then immediately boots from flash and runs again. I have now added a ‘while’ loop waiting for an external processor port to be pulled low just before the main code configures and enables the data i/o interrupts. The ‘Target’->’continue’ downloads without error every time, the main code (and interrupts) then only run after you press a push button connected to the port.
