I'd like to peek at the bootloader source code, so I found https://github.com/bitcraze/crazyflie-bootloader, but the readme.md says:
Note: This is the bootloader for the first Crazyflie nano quadcopter. Crazyflie 2.x has a different bootloader.
For some reason no bootloader is listed at the top level of bitcraze github, where is the crazyflie 2.x bootloader?
Thanks,
