CubeOrange bootloader, supports PX4?

Hi, I am a PX4 developer and I am working on a port for the Cube Orange.

Is the Ardupilot bootloader compatible with PX4? If not, support for PX4 will be much more difficult. As I understand it, this would require every CubeOrange to be taken apart and flashed via the debug port on the bottom of the carrier board.

Any help is greatly appreciated, thanks!

QGC can load any firmware you want onto the cube.
