wiki cee Firmware update troubleshooting Edit

If the CEE fails to enumerate on USB, or is unresponsive, you can manually enter the bootloader to flash a corrected firmware.

  • Unplug the CEE
  • Short the BOOT and GND pins together on the 6-pin programming header
  • While shorting those pins, plug in the USB cable.
  • The blinking LED indicates that the bootloader is active. Refresh the firmware update page and try again
