Recovering a Bricked Notecard

In the event the wrong type of firmware was inadvertently uploaded to your Notecard, you may need to manually recover the "bricked" Notecard using a Notecarrier A or Notecarrier F.

Recovering a Notecard with Notecarrier A

1. Download the appropriate firmware binary for your specific Notecard.
2. Plug the Notecarrier A into your PC via a micro USB cable.
3. Add a jumper wire between the unmarked BOOT pin and VIO on the Notecarrier A (see image below for location of BOOT).
4. Add another jumper wire between RST and GND.
5. Remove the RST/GND jumper.
6. Remove the BOOT/VIO jumper.
7. The Notecard will now be in its bootloader, so you can follow instructions provided to manually update the firmware.

Recovering a Notecard with Notecarrier F

1. If there is a host MCU in the Feather socket, remove it.
2. Download the appropriate firmware binary for your specific Notecard.
3. Plug the Notecarrier F into your PC via a micro USB cable.
4. Add a jumper wire between N_BOOT and N_VIO.
5. Press the small reset button next to the Notecard (see image below).
6. Remove the BOOT/VIO jumper.
7. The Notecard will now be in its bootloader, so you can follow instructions provided to manually update the firmware.
