As the IAR ports for Musca A and psoc64 are more or less complete,
    I've started looking at the MPS2/MPS3 targets.
    
    After some initial issues I can now connect our debugger via USB
    using CMSIS-DAP. However I'm not getting and serial ports configured
    on my Win10 laptop when connecting to an MPS2+ board running the
    AN521 (M33) image. Shouldn't that show up automatically like it does
    with the MPS3? Or do I need to use the physical serial port on the
    board?
    
    I would appreciate reviews of the IAR port as well, see

    Thanks,
