I am using several CUAV Pixhack V3x. To use all 3 IMUs and both Barometers it is necessary to use the firmware FMUv3. With using Pixhawk1 firmware one gets only 2 IMUs and 1 Barometer. Also Compass_DEV_ID2 is not visible (see pictures).
It would be great if one could also choose FMUv2 in the firmware builder. Could you please make that possible. Thanks a lot for your great work.
