I have my first Pixhawk Cube, I have the latest firmware 3.9.8 and I have this question:
When I connect the cube to the PC with an USB cable it first connects as “Legacy FMU (COM 4)” and lights are: 1 flashing red and 1 solid red. Then change to 1 solid red, then 1 flashing red and it changes to “USB Serial device (COM 7)” and the lights stop flasing.
I can connect with Mission Planner through COM 7 and all seems OK, but no lights are ON. Is that OK? Or some light has to be on?
I saw on a youtube video that after flashing firmware and connecting to MP a green light is on.
