4) Next, click “Load Firmware” in the bottom right corner of the page and select the Betaflight firmware file downloaded from the product page in Step #1. Click “Flash Firmware” to begin the firmware download to the flight controller.

5) Allow a minute or two for the firmware to download to the flight controller. Once complete, the Betaflight Configurator will read “Programming: SUCCESSFUL” at the bottom of the page. Congratulations, your flight controller is now running Betaflight and ready for additional configuration!

How to flash Ardupilot

There are multiple ways to flash Ardupilot, but using the STM32CubeProgrammer is the easiest method if the flight controller is NOT running Ardupilot. Please see the official Ardupilot documentation for additional information.
Skip to the QGroundControl section if the flight controller is already running Ardupilot.

STM32CubeProgrammer (Flight controller NOT running Ardupilot)

1) Navigate to the Lumenier LUX F765 product page and download the latest Ardupilot firmware file – abc_LUXNDAAF7_arducopter_x.y.z_with_bl.hex.
2) While holding down the “BOOT0” button on the flight controller, plug a USB-C cable into the flight controller and your PC. Only the flight controller’s red LED should be lit.
3) Open the STM32CubeProgrammer and select “USB” in the configuration tab on the right side of the application. Next, click the refresh button and then
“Connect” if the flight controller is found in DFU mode. Target information should populate in the bottom right-hand side of the window if a connection is established. If the flight controller is not found, return to Step #2.

4) Navigate the the “Erasing and Programming” window by clicking the download arrow on the left side of the page. The window should open and look similar to the image below.

5) Next, click browse and select the Ardupilot firmware file downloaded from the product page. Click the check boxes for “Verify programming” and “Run after programming”. Finally, click “Start Programming” to flash the Ardupilot firmware onto the flight controller.
6) Allow a minute or two for the firmware to download onto the flight controller. Once complete, the STM32CubeProgrammer will report “File Download Complete”. Congratulations, your flight controller is ready for additional configuration in QGroundControl or Mission Planner!

QGroundControl (Flight Controller is already running Ardupilot)
