my APM 2.5 just stopped working. When I connected it to Mission Planner via USB (battery not connected) it began to update the values as normal. But then in the middle of the job it just froze. Now I cannot connect to the Mission Planner anymore ("no hartbearts"), execept in terminal mode. There it says: "No dataflash inserted"
Is my APM broken? Is there a possibility to fix it?
All the best,
