M5 Card Computer NOT respond
-
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
