Ocotopter Lumenier LUX-F7 "PWM Init Error"

[hoglibogli]

I try to setup Ocotopter Flat X on Lumenier LUX-F7 (Matek F722SE Target).
INav wont arm saying: "PWM init Error".
In the output tab only Motor 1-6 seem to be assigned.
If I configure it as Quad it will arm and motors spin.
All 8 Motors work in Betaflight.
I guess it has to do with the output mapping in INav.
What can I do?

Thanks

(Im using INav 2.6.1)

I think I found the answer. I need another FC. The Matek F722SE supports only up to 6 Motors with multishot. I will get the Matek F722 PX that will support 8 Motor Outs with INav.
