      Dear all
      I just received my M5 Card Computer and it's comes with M5 Cardputer User Demo Plus and i burn UIFlow2.0 on it and I decided to change the firmware to Cardputer User Demo Plus but I get an error message (( A fatal error occurred: Failed to connect to Espressif device: No serial data received.
      For troubleshooting steps visit: https://docs.espressif.com/projects/esptool/en/latest/troubleshooting.html))

      Don't know what to do
      thanks

        @qatar20-22 you didn’t erase the cardputer before burning firmware

        UIFlow, so easy an adult can learn it!
        If I don't know it, be patient!
        I've ether not learned it or am too drunk to remember it!

        M5Black, Go, Stick, Core2, and so much more it cant be fit in here!
