Hi Everyone;

I try to use Pixhawk 2.4.8 + Raspberry Pi 4 2GB + BlueOS + SUB Official 4.0.3 firmware combination. I installed BlueOS into Pi 4 and also installed Sub Official 4.0.3 firmware into Pixhawk 2.4.8. I made all sensor calibrations and joystick calibrations. All work well. But  
I am getting the error that the flight mode parameters are missing.

Hi @MkCkyk03, welcome to the forum 🙂

Missing parameters like this can sometimes occur if the vehicle doesn’t get detected properly by QGroundControl.

1. Is it happening consistently, or did this just occur once?
2. Which QGroundControl version are you running?
3. Does the error still appear if you open QGroundControl after the vehicle is turned on and connected to the topside computer (or if you re-open it after the vehicle connects)?
