Uninstalling the PX4 Bootloader and Firmware

I flashed the PX4 bootloader and firmware onto my Bitcraze Crazyflie 2.0 and now I want to start using the original Bitcraze firmware again. However, I’m unable to do this because PX4 is interrupting the flashing process. Is it possible to remove PX4?

Good day,
if your board have a jtag connector you can reflash the original bootloader. just in case you don’t have it soldered on your board you need the Bitcraze Crazyflie 2.0 debug adapter.

Thanks for the reply,

The CF2 appears to have that jtag connector you mentioned. I downloaded the original Bootloader from github (https://github.com/bitcraze/crazyflie2-stm-bootloader) and tried to ‘make’ it but I get the following message:

Do you have any ideas on how to prepare the bootloader?
