4.4.0 to 4.5.2 Firmware upgrade issue for Matek F765 Wing

I can not get my Matek F765-wing upgraded from 4.4.0 to 4.5.2 Firmware.

The FC DFU mode doesn’t seem to be working on my two PC’s. They can’t see “DFU” mode, but both PC’s do work with other FC just fine.

Other than pulling the FC out of the plane and using a STlink what are my options?

You don’t need to enter DFU mode to flash an update. Just connect via USB, open Mission Planner, and accomplish the firmware update.

I forgot to say, the “normal” MP upgrade errors out each time.

Go here Matek F765-wing and downlead the .apj file and use Mission Planners “load custom firmware” to flash it.
If that doesn’t work use QGroundControl to flash ArduPlane firmware for the board. If Ardupilot was ever on the board forget about DFU unless you flashed it back to Betaflight/Inav.

QGroundcontrol did work thank you
