Resetting Flight Controller Settings

I. Principle

In INAV firmware, flight controller configuration parameters may become abnormal due to misoperation, incorrect debugging, or incompatible upgrades. At this point, you can reflash the firmware and clear all parameters to restore the flight controller to its default state, ensuring stable system operation.
The primary method for clearing settings is to check the "Erase all data" option when flashing firmware, ensuring all old parameters are cleared rather than沿用 the previous configuration.

II. Equipment Preparation

1) Flight controller: CoreWing F405 WING V2 / SpeedyBee F405 WING APP / SpeedyBee F405 WING MINI / Any flight controller is applicable to this tutorial.
2) USB data cable: For connecting the flight controller.
3) Ground control station: INAV ground control station.
