      I had my expansion board working with both until yesterday. I tried with 2 LoPy and the result is the same, however when I put my WiPy it is working fine. I also have an expansion board v1.0 and the result is the same.

      I tried to update one of the LoPy's firmware and it is now booting with the LED permanently red. Even in safe boot after being ORANGE it stays RED.
      I have been able to connect to my other LoPy with minicom via Linux (and now it is working again via widnows) but the other one seems bricked.
      Any idea of what to do ?

      Thank you in advance,

      Benjamin

        @bnjroos try to erase the flash of the "bricked" LoPy with the esptool.py form the esp-idf repository https://github.com/espressif/esptool/tree/96698a3da9acc6e357741663830f97524b688ade
        Use
        python3 esptool.py -.port com_port --baud 230400 --chip esp32 erase_flash
        and then update the device again.

          python3 esptool.py -.port com_port --baud 230400 --chip esp32 erase_flash

          It worked like a charm, thank you a lot !

            @robert-hh Issue appeared again and previous trick did not work this time unfortunately :(

            And it worked again after several tries.

              For anybody else that might have this problem, before trying to erase the flash you need to have a wire connected between G23 and GND and reset the board.
