Flash over the air after manual flash

[Slaxx]

I tried to install other Operating Systems on the Crazyflie. At this moment I want to set back the CF to its factory state such that I can flash the Firmware over the air. I tried flashing the cflie.bin over the ST-flash tool but I'm still not able to flash over the air. The CF is running fine though. What do I have to flash in order to set it to factory state?

Thank you for the great work

I think you are missing the stm bootloader. Flash that first and then put it in bootloader mode and you should be able to flash it over the air.

OK thank you. I'll give it a try

OK I could flash over the air, but now the blue light at M2 is constantly lit when powering on and the props dont spin as initialization.

If I take flash over debugger, then it works.

Edit: Now I can't even flash over the air anymore:

make cload
../crazyflie-clients-python/bin/cfloader flash cflie.bin stm32-fw
Restart the Crazyflie you want to bootload in the next 10 seconds ... Cannot connect the bootloader!
Makefile:261: recipe for target 'cload' failed
make: *** [cload] Error 255

Edit2: In addition I realized that the yaw is drifting at 1°/sec. Is that normal?
