crazyflie 2.0 died - one light on and no response

Post by junchen » Thu Oct 04, 2018 7:53 pm

Hi,

I got the problem when booting the crazyflie 2.0. It died after flashing the firmware. The M2 is always on until unplugging the battery and besides that, the crazyflie has totally no response to everything. Anyone has ideas of that?

Thanks,
Jun

It sounds like the flashing procedure has not worked properly. You can try again by putting your Crazyflie in bootloader mode again (then both blue LED will blink) and by flasing the firmware again.

As a side note it is not possible to erase the bootloader from the bootloader, this means that you should always be able to flash again. Worst case you will have to unplug the battery, press the button, plug the battery again and wait for the blue LED to start blinking to release the button. The Crazyflie will be back in bootloader mode.

Thank you so much for your response. I followed your instruction and finally enter the bootloader mode again. After flashing the firmware it worked!
