Mon Feather n'est plus reconnu!
My Feather M0 won't enumerate anymore and can't be programmed, help!
If something happens and your Feather M0 won't enumerate as a USB serial device, like perhaps you were exploring the ATSAMD21's peripherals and accidentally misconfigured something, don't worry you can try a few things to revive it back to normal.
- First try pressing the reset button twice like a mouse double click. The LED should start pulsing red to inform you the chip has entered its bootloader and is waiting a program upload.
- The Feather M0 will show up as a new COM port device (if you haven't already installed the Windows drivers, do that!)
- Select the new bootloader COM port in the Arduino IDE
- Now try uploading a simple blink example from the Arduino IDE to see if that gets the board back into a good state.
If you don't get a pulsing red LED and the board doesn't enumerate as a serial device then something has happened to the bootloader. Unfortunately the best option in this case is to connect to the single-wire debug test points on the back of the board (the SWDIO & SWCLK pads) and manually reprogram the bootloader using a J-Link or ST-Link ARM programmer.
