How to overwrite FC params without USB connection

PX4 Autopilot
1

I was playing around with some params in QGC and set SYS_USB_AUTO to disabled. This now means that my FC does not recognize the usb port and it wont connect to QGC or anything. I have tried to wipe the memory via DFU and add new bootloader but it seems the param i set still persists

Does anyone have a worked around that will allow me to overwrite that param i initially set

I have tried so far using dfutil and wiping memory and adding new bootlader

Hi, usually there is another mavlink stream on a telemetry port (TELEM1 or TELEM2) that will allow you to connect to the FC. If you have any radio, you can plug it in the telemetry ports and connect to FC and change the parameter you want. Another way is to put parameters on the SD card (see System Startup | PX4 Guide (main)). These will overwrite everything else.

Ended up having to use a ST LINK to wipe the FC clean.

Great tutorial if anyone needs
