I just turned on my crazyflie today, it self-tested and connected to my pc, but there is a red flashing light on it and it won't fly. Any help would be appreciated. I have tried tapping it as per the troubleshooting guide, I don't really understand what is going on.

Something happened with the pressure sensor chip, probably soldering that has gone bad. You can contact Seeedstudio support to get it fixed. I have also attached a firmware that disables the pressure sensor functionality so it will work again without it (altitude hold will not work).

Thanks so much, I have contacted seeedstudio.com, but the firmware is just what I need in the meantime. I can keep working without the pressure sensor. Thanks again

I have the same issue. Will the new board cost me anything?
