Bootloader Flashing Using DFU

PreviousBetaflight InstructionsNext3D Models

Last updated 4 months ago

DFU can be used to flash or reflash the bootloader with the following steps.

  1. With the board unpowered, hold the button next to the USB C port while connecting the USB cable to your PC.

  2. Open in Chrome.

  3. Select Connect, then select DFU in FS Mode.

  4. Now select the @Internal Flash option.

  5. Now choose the bootloader binary you wish to flash. In this case we are using the default ARK FPV PX4 bootloader which is compatible with PX4 and Ardupilot.

  1. Select Download to flash the firmware.

  2. The flash will finish and the firmware will start.
