I now have the ‘Bad or no terrain data’ error when planning a terrain following mission in my plane. Terrain following enabled in parameters in mission planner. See screenshots.
When connected to my laptop in Mission Planner it’s not showing any altitude which it always did (circled) and the terrain data remains pending and doesn’t load. The Pixhawk main light is flashing yellow.
The GPS module green light is on, and the blue light flashing.
I have tried older firmware in the Pikhawk and an earlier Mission Planner, formatted and changed SD cards and even swapped in my other Pixhawk but no change. This just suddenly started.
