I found a problem that eludes me. I’ve been having trouble with the Pixhawk4 mini connecting and communicating with the Ground Control software, (QGC), so I decided to try updating the firmware when I noticed it said it was already programed with Ardupilot - ChiBios. It is my understanding the flight controller is PX4 - NUTTX Bios. I updated the firmware anyway and checked again and it still says Ardupilot - ChiBios. Can anyone give me an idea of how to correct this?
