0 PWM on AUX 1,2,3,4

Hi all,
I am ironing out some final things on a 3DR X8M with Pixhawk and Copter 3.3.2.
The main probem I have right now is:

After bootup on AUX 1,2,3,4. has -1 PWM.
BRD_PWM_COUNT=6,
Line 4710: RCOU, 11223568, 990, 990, 990, 990, 990, 990, 990, 990, -1, -1, -1, -1
Line 5035: RCOU, 11324467, 990, 990, 990, 990, 990, 990, 990, 990, 1900, 0, 0, 0

Not only does it refuse to keep the PWM values @trim, it also forgets to log AUX 5+6. AUX 5 has the gimbal tilt control.
Main thing is to have the trim working on aux from bootup.
can anyone help?
