| + | ====== Crazyflie bootloader ====== | ||
| + | The Crazyflies have a radio bootloader pre-programmed. It allows to flash all firmwares over the air using Crazyradio. The boot loaders cannot erase themselves so it is always possible to restart the Crazyflie in bootloader mode. | ||

| + | ====== Entering bootloader ====== | ||
| + | The bootloader can be entered in two ways: Cold-boot and warm-boot. | ||
| + | |||
| + | ===== Cold booting ===== | ||
| + | The procedure to cold-boot the bootloader depends of which Crazyflie you are using. | ||
| + | |||
| + | For Crazyflie 1 start the bootloading sequence on the PC and restrart the Crazyflie. | ||
| + | |||
| + | For Crazyflie 2, press the ON/OFF switch more than 1.5 second until the blue led blinks. Then release the button and the two blue leds should blink. | ||
| + | |||
| + | ===== Warm booting ===== | ||
| + | |||
| + | Warm booting is done when the Bootloader client restarts the Crazyflie in bootloader more automatically. While implemented in firmware this mode is not yet implemented in the PC client. | ||
