Bug report

Issue details

We have a custom-developed autopilot board based on Raspberry Pi (Linux). The firmware cloned from the ArduPilot master branch runs without any issues. However, when using the firmware cloned from the ArduPilot-4.6 and ArduCopter-4.5 stable branches, we encounter the error "INS: Unable to initialise driver" at startup, followed by repeated "Config Error: INS: Unable to initialise driver" messages. Upon inspection, we noticed that the driver for the BMI270 sensor is never initialized. The corresponding backend class is not instantiated at any point.

Version ArduPilot-4.6 ArduCopter-4.5

Platform [ ] All [ ] AntennaTracker [x] Copter [ ] Plane [ ] Rover [ ] Submarine
