We have been trying to install PX4 (1.12.1) into 2 Cube Oranges (from different production batches, purchased 2 years apart), and failing. We have tried using the latest QGC and MP. It looks like the installation is successful, but when it restarts, the Device Manager (in windows 10) reports two ports, a Bootloader port (and it does work as bootloader for flashing new firmware) and a Mavlink port with an “!” in a yellow triangle. The Mavlink port information in Windows report a Code 10 error, “does not start”. And neither MP or QGC manages to connect. I am also unable to connect using TELEM1 port, which I would assume by default should be active (it is on Ardupilot after flashing with that, without any configuration).
We have tried using 2 different Windows 10 laptops, with slightly different hardware setups and time of installation of software, one was clean and started with a clean install of QGC to begin with.
It might be a driver problem, but we do get Black cube with PX4 to connect to the laptop, so we are not convinced it is that, but are wondering if it might be some problem preventing proper startup of the software onboard. Any help or suggestions would be most welcome, since the Black cube is no longer in stock almost anywhere.
