Building/Flashing

To place the crazyflie2 into DFU mode:

Remove all power (battery and usb)
Hold down button
Insert power
Blue light will go solid blue
Blue light will start blinking
Blue light will start blinking rapidly
Once the Blue light starts blinking rapidly release the button and plug into your computer, it will show up in DFU mode and the instructions below can be used to flash it

git clone -b crazyflie2 https://github.com/exec-all/micropython/
BOARD=CRAZYFLIE2 make
dfu-util -a 0 -D build-CRAZYFLIE2/firmware.dfu
