      Hello
      I am trying to upload code into my LoPy4 via the expention board. I could it until I lost connection.

      I reconnect the USB cable and look at More->Get Serial Port

      The only thing I can see it

      /dev/cu.iPhonedePierrot-Wireles (copied to clipboard)
      Connecting on /dev/cu.usbserial-DQ00DAHG...
      

      But it can not see my USB port.

      What can I do?
      I rember, we could reset the board? Isn't?

      Thank

        @pierrot10 which model of the expansion board arte you using. Version 2 (one push button) or version 3 (two push buttons). Version 2 is more simple. If you cannot see the serial port, it is a problem of the physical connection (cable, jumpers on the board) or the OS X driver. Version 3 adds to the list of trouble sources the firmware in the PIC controller on the board.
        I assume that you also do not get a REPL prompt.
