ArduPlane/CubeOrange+ compatibility

Hi all,
I received some brand new CubeOrange+. I have an issue with those new ones, I can’t load firmwares older than Plane-4.4.2.
I was using Plane-4.2.3 on other drones and I wad wondering if this new generation of CubeOrange+ was able to run this firmware.
To be more precise, I can load firmwares but I have this error when I connect the cube to MissionPlanner:

I tried to use QGround and to upgrade my MP but nothing changed…
Thank you !

The Cube Orange Plus has some newer components that are not catered for in earlier firmware.

Thank you for your answer !
