Loading Firmware

QGroundControl desktop versions can be used to install PX4 firmware onto Pixhawk-series flight-controller boards.

Before you start installing Firmware all USB connections to you vehicle must be disconnected (both direct or through a telemetry radio). The vehicle must not be powered by a battery.

To install the latest firmware update:

  1. First select the Gear icon (Vehicle Setup) in the top toolbar and then Firmware in the sidebar.

  2. Connect the flight controller directly to your computer via USB.

    Connect directly to a powered USB port on your machine (do not connect through a USB hub).

  3. Once the controller is connected you can choose which firmware to load (QGroundControl presents sensible options based on the connected hardware).

  4. Select the PX4 Flight Stack XXX Release option to install the latest stable version of PX4 for your hardware (autodetected).

    Install PX4 default

    To install a different version of PX4, check Advanced settings and select the version from the dropdown list.

    Install PX4 version

    • If you select Custom firmware file you will need to choose the custom firmware from the file system in the next step.
  5. Click the OK button to start the update.

    The firmware will then proceed through a number of upgrade steps (downloading new firmware, erasing old firmware etc.). Each step is printed to the screen and overall progress is displayed on a progress bar.

    Firmware upgrade complete

    Once the firmware has completed loading, the device/vehicle will reboot and reconnect.

Next you will need to specify the vehicle airframe (and then sensors, radio, etc.)

If QGroundControl installs the FMUv2 target (see console during installation) and you have a newer board, you may need to update the bootloader in order to access all the memory on your flight controller. See Bootloader Update for more information.
