This flashes both firmware to the crazyflie drone and the deck:
Extra Notes
The flashing from Cold boot (recovery) part is optional. It’s only needed if the crazyflie’s firmware is unknown and outdated.
During the flashing, the “Status” label might show “Identifying deck to be updated” and might be stuck there for a long time.
If it’s stuck for more than 1 minute, it might be because the drone is calibrating the IMU. Try holding it up and help it move in all directions and orientations. The drone should blink and emit a sound when that’s done. After that, the deck flashing should continue.
It’s also fine to unplug/power-off the drone and repeat the whole flashing process, if the step is stuck for more than 3 minutes. The
cfclientGUI might need to be re-started, too.
