PX4, Cube Orange, Hobbywing X 6/8/9 combo

We are trying to get a hexa working with Cube Orange and Hobbywing X9 motors and corresponding FOC ESC’s (X9 combo). Connecting with PWM is not working. We can’t get the motors connected to PX4 1.11.3. The ESCs are beeping although everything is connected correctly. When using a cube black with 1.11.3 it works fine. Anyone having the same or similar issue?
Latest stable release PX4 seems not to be working with the FOC ESCs or are we missing something?
