Hi.
I was trying to do some tests and alterations in the crazyflie firmware but I did a stupid mistake and screwed up everything. I made a kind of infinite loop before the initialisation of the drivers, so now I can't flash other firmware via radio.
Do you know how can I flash a new firmware in my quadcopter? I was thinking about do it straight to the micro-controller via USB. Is it possible? If yes how can I do it?

Help me please!!!

Thank you.

You shouldn't be able to overwrite the bootloader when flashing using the Crazyradio. It should be OK to flash it using the cfclient.

Unfortunately the CF1 does not have a USB bootloader but you shouldn't be able to brick it without a JTAG anyway (and then you can restore it).

For CF1 you can't flash it over USB. If you truly overwrote the bootloader, I believe you need to flash it with JTAG. That said, you likely didn't overwrite the bootloader if you were just flashing firmware. You can try to reflash the default firmware or a different working version. Please see the thread here for a little more discussion. Post back if you need further guidance.

Haha. Oops. Tobias answered while I was writing my response. Anyway, good luck!

Cheers.

Hi, I just flashed the firmware without any problem.
Thanks for helping!
