## 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.

## Auto-Arming on Boot
The vehicle can be configured to arm automatically on boot once all preflight checks pass,
using the `COM_ARM_ON_BOOT` parameter. For safety, PX4 enforces a minimum 5-second delay after boot before attempting to arm.
Once armed this way, the vehicle will not re-arm automatically after a manual disarm.
:::info
The parameter value is read once at boot.
Changing it while the system is running has no effect until the next reboot.
:::
:::warning
Use with caution.
A vehicle that arms automatically can spin up motors and actuators without any operator gesture.
Ensure the vehicle is in a safe state before powering on.

## Pre-Arm Checks
To reduce accidents, vehicles are only allowed to arm certain conditions are met (some of which are configurable).
