## PX4 Bootloader Update {#bootloader}

The board comes pre-installed with [Betaflight](https://github.com/betaflight/betaflight/wiki).
Before the PX4 firmware can be installed, the _PX4 bootloader_ must be flashed.
Download the [holybro_kakuteh7-wing.hex](https://github.com/PX4/PX4-Autopilot/raw/main/docs/assets/flight_controller/kakuteh7-wing/holybro_kakuteh7-wing_bootloader.hex) bootloader binary and read [this page](../advanced_config/bootloader_update_from_betaflight.md) for flashing instructions.

## 펌웨어 빌드

To [build PX4](../dev_setup/building_px4.md) for this target:

```
make holybro_kakuteh7-wing_default
```

## 펌웨어 설치

:::info
KakuteH7-wing is supported in PX4 v1.16 or newer.
Prior to that release you will need to manually build and install the firmware.
:::

Firmware can be manually installed in any of the normal ways:

- Build and upload the source:

  ```
