Hi! I am trying to do the compass calibration of my px4 with black cube, but I can´t. I assume it is because there is the error message “failed to initialize MAVFTP” when I connect with mission planner. When I try to arm the vehicle, I get the error “no response from MAV” and also when I go to compass, sometimes I got the error in the image. I can´t find anything online to solve this problem and I am not sure why I can´t do the calibration anymore as it was working some time ago. Just in case I have downloaded the latest version of mission planner and plane firmware. I have also tried to connect through to px4 externally with a telemetry antenna or connected to the computer, but still not working, so please help me!
Thanks!
