Update instructions

It is recommended to keep your FaultyCat updated to ensure its correct functionality. The firmware can be updated manually with a computer.

  1. Connect the board to your computer via USB.

  2. Enter the board to bootloader mode. This will open RP2040’s mass storage folder on your computer.

  3. Download the latest faultycat_vX.X.X.X.uf2 file.

  4. Drag and drop the .uf2 file into RP2040’s mass storage folder. The mass storage folder will be closed once the firmware is uploaded correctly.

[!Note] You can also use the command faultycmd update on your faultycmd installation. Learn more here: FaultyCMD - Update firmware

Bootloader mode

Bootloader mode is useful when the board is not working properly and the firmware must be flashed. Enter bootloader mode by following the button sequence:

  1. Press and hold the BOOT button, then turn on the board by either:
  • Slide the power switch (SW2) to ON.
  • Plug the board into a USB port while SW2 is set to ON.
  • Perform a hardware reset by pressing the RESET button.
