- Most boards will need to use the [Debug Probe](#debug-probe-bootloader-update) to update the bootloader.
|
||||
- You can use [QGC Bootloader Update](#qgc-bootloader-update-sys-bl-update) with firmware that includes the [`bl-update` module](../modules/modules_command.md#bl-update).
|
||||
This is the easiest way to update the bootloader, provided the board is able to load firmware.
|
||||
- You can also use the [Debug Probe](#debug-probe-bootloader-update) to update the bootloader.
|

This is useful for updating/fixing the bootloader when the board is bricked.

- On [FMUv6X-RT](../flight_controller/pixhawk6x-rt.md) you can [install bootloader/unbrick boards via USB](bootloader_update_v6xrt.md).

This is useful if you don't have a debug probe.

- On FMUv2 and some custom firmware (only) you can use [QGC Bootloader Update](#qgc-bootloader-update).

## QGC Bootloader Update (`SYS_BL_UPDATE`)
|
||||
|
||||
The easiest way to update the bootloader is to first use _QGroundControl_ to install firmware that contains the desired/latest bootloader.
|
||||
You can then initiate bootloader update on next restart by setting the parameter: [SYS_BL_UPDATE](../advanced_config/parameter_reference.md#SYS_BL_UPDATE).
|
||||
|
||||
This approach can be used if the [`bl-update` module](../modules/modules_command.md#bl-update) is present in the firmware.
|
||||
The easiest way to check this is just to see if the [SYS_BL_UPDATE](../advanced_config/parameter_reference.md#SYS_BL_UPDATE) parameter is [found in QGroundControl](../advanced_config/parameters.md#finding-a-parameter).
|
||||
|
||||
:::warning
|
||||
Boards that include the module will have the line `CONFIG_SYSTEMCMDS_BL_UPDATE=y` in their `default.px4board` file (for examples [see this search](https://github.com/search?q=repo%3APX4%2FPX4-Autopilot+path%3A**%2Fdefault.px4board+CONFIG_SYSTEMCMDS_BL_UPDATE%3Dy&type=code)).
|
||||
You can enable this key in your own custom firmware if needed.

## FMUv2 引导加载器更新

|

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.
|
||||
This example explains how you can use [QGC Bootloader Update](qgc-bootloader-update-sys-bl-update) to update the bootloader.

:::info
|

Early FMUv2 [Pixhawk-series](../flight_controller/pixhawk_series.md#fmu_versions) flight controllers had a [hardware issue](../flight_controller/silicon_errata.md#fmuv2-pixhawk-silicon-errata) that restricted them to using 1MB of flash memory.
