In this firmware, the gyroscope will be calibrated automatically on startup.
When this feature is enabled, the gimbal automatically calibrates the gyroscope on startup. This process takes more time than before, but the gimbal's performance is better. Please do not touch the gimbal when the led indicator flashes white while it is being calibrated. If the calibration is failed, the led indicator shows yellow color. If the calibration is complete, the gimbal will start working properly.
If you want the gimbal to start up faster, you can disable this feature. Note that you should disable this feature if you need moderate image quality and fast boot times
