Crazyflie sometimes can't boot after flashing the firmware

Post by MadeInPierre » Thu Oct 10, 2019 1:27 pm

Hi all,

I am currently modifying the crazyflie firmware for my own use case, and I use the regular `make cload` command to flash the crazyflie.

The problem I am experiencing is that the drone sometimes fails to boot after flashing the firmware, even though the same code runs on another drone or on the same drone after a few tries. I sometimes have to flash the firmware up to 10 times until the drone successfuly boots, which gets pretty tedious to do...

Does someone have an explanation on why this happens? Could it be a packet loss while transfering the firmware through the crazyradio, or some other cause? Would you have advices on how to reduce the failure rate?
Thanks!

P.S: As a side question, I couldn't find a way to flash the drone through a regular USB cable but this could maybe help to solve the issue?
