I have been able to write firmware to the RDDRONE-FMUK66 board, I have tried using the segger debugger and it is able to recognise the board but it cannot connect.
In addition when I try to upgrade the firmware using qgroundcontrol it does not work either, I get the following message:
Found device: PX4 FMUK66 v3.x
Connected to bootloader:

Plug in your device via USB to start firmware upgrade.
