Unable to burn M5 Core 2 COM port not available

  • C

    Hi there,

    I am facing a silly issue. My Core 2 runs a programme that uploads Temp data to a cloud server.
    The program runs in autostart mode, after having finalized it in Run mode, I uploaded it.
    I would like to burn the firmware again to start a new project

    The issue is that the COM port does not show up when I connect the device to my computer.
    I suspect that the program is monopolizing the COM port. I have been tryng several attempts : remove the Unit to have the program crash, shut down the program.. No success.

    Could you give me advice on how to recover my COM port ?
    Thanks for your suggestions

    You may disregard this post. I changed for another USB cable and was able to recover COM3
