펌웨어 설치 및 업데이트

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

WARNING

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

PX4 안정 버전 설치

Generally you should use the most recent released version of PX4, in order to benefit from bug fixes and get the latest and greatest features.

TIP

This is the version that is installed by default.

PX4 설치

1. Start QGroundControl and connect the vehicle.

2. Select "Q" icon > Vehicle Setup > Firmware (sidebar) to open Firmware Setup.

   

3. USB를 통해 비행 콘트롤러를 컴퓨터에 직접 연결합니다.

   INFO

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

:::

4. Select the PX4 Pro Stable Release vX.x.x option to install the latest stable version of PX4 for your flight controller (autodetected).

   

5. Click the OK button to start the update.

   펌웨어가 업그레이드(펌웨어 다운로드, 이전 펌웨어 삭제 등)를 진행합니다. 각 단계 화면을 표출하고, 전체 진행률이 표시줄에 출력됩니다.

   

   펌웨어의 업로드가 완료되면, 장치가 재부팅되고 다시 연결됩니다.

   TIP

   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.

:::

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

Installing PX4 Main, Beta or Custom Firmware

다른 버전의 PX4 설치

1. Connect the vehicle as above, and select PX4 Pro Stable Release vX.x.x.
2. Check Advanced settings and select the version from the dropdown list:
   • Standard Version (stable): The default version (i.e. no need to use advanced settings to install this!)
   • Beta Testing (beta): A beta/candidate release. 신규 버전 출시 이전에 테스트 할 경우에만 사용할 수 있습니다.
   • Developer Build (master): The latest build of PX4/PX4-Autopilot main branch.
   • Custom Firmware file...: A custom firmware file (e.g. that you have built locally). 사용자 정의 펌웨어 파일을 선택한 경우 다음 단계에서 파일 시스템에서 사용자 정의 펌웨어를 선택하여야 합니다.

그러면 펌웨어 업데이트가 이전과 같이 계속됩니다.

부트로더 업데이트

Pixhawk hardware usually comes with an appropriate bootloader version pre-installed.

A case where you may need to update is newer Pixhawk boards that install FMUv2 firmware. 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.

You can update it by following the instructions in Bootloader update > FMUv2 Bootloader Update.
