Dodecarotor cox x12 with px4

hi everyone, i am trying to buil a x12 with pixhawk cube, there is an airframe reference in link below that i used, but i couldn’t make it work, 6 top motors are running correctly but 6 bottom motors are just beeping, how should i tell my pixhawk to use AUX for bottom motors?

Have excatly the same problem here. Anyone could solve this?
