3 year old 3DR Y6 kit with APM2.6, two crashes in that time, but cannot seem to get it back to stable. I noticed that in terminal mode, after connect, it displays "ublox" then garbage keeps being displayed. Not sure if the GPS/Compass took the brunt of both crashes, or what. In flight it tends to roll left. I am starting at the beginning (re-flash firmware to 3.2.1), calibrate, etc.
Does anyone know from the photo perhaps the culprit on the garbage it keeps reading out?
