Arducopter 3.5.5 was fine with Oneshot125 with Navio2 and Edge.
Oneshot125 is broken since Arducopter 3.6 (and 3.7dev).
Some new hardware like LIS3MDL compass is available and supported by arducopter. Could you include this option in the available compiled binaries?
Emlid Edge image and QGroundControl for Edge are one year old. We could benefit of latest QGroundControl features and ardupilot evolution.
Latest 3.6.10 rc1 doesn’t launch on Navio2. Both with 2018 and 2019 distribution. 3.6.9 is OK
