@crossa on which hardware?

crossa commented 7 years ago

@julianoes px4firmware v1.6.3 on linux based hardware such as raspberry pi ,nano pi. I meet this issue yesterday. I was going to do the upgrade operation but give it up . I have tried find the cause of the error but faild.

@julianoes I think the px4firmware cause the iusse. If "ERROR [sensors] Mag #0 fail: STALE!" display, I can calibrate the mpu9250 senor with mag in the QGC，but it's useless .After the calibration, the driver does not work. I use the mag of mpu9250 as mag #0, I don't know whether it will work correctly if I use another independent mag .

@LorenzMeier please check it

@julianoes @LorenzMeier At Firmware/src/modules/sensors/voted_sensors_update.cpp line 897 bool VotedSensorsUpdate::check_failover(SensorData &sensor, const char *sensor_name) AND line 912.

I don't know why the mag can not pass the check
