Alex,
I've had some more luck this week. I am able to get motors spinning with the newer M0065 board. The SDK 1.1.2/voxl-suite/voxl-px4 package did not have the parameter VOXL2_IO_PWM, so I could not set it via QGroundControl and px4-param set would fail too (although I could set VOXL2_IO_FUNC1/2/3/4). After reinstalling the SDK a few times, the missing parameter finally appeared. Also, I assumed that in the voxl-px4.conf file that setting ESC=VOXL2_IO_PWM_ESC would set everything up, but VOXL_ESC_FUNC1/2/3/4 parameters were still left as 101/2/3/4 and causing issues as well.
Based on your last reply, a solid orange LED seems to not be a problem, since I'm using an SBUS receiver, and it is probably sending data at a high rate to the flight controller.
The ESC calibration process fully completes, actuator test is functional, and the motors spin-up after arming now. I believe the solid orange LED was a non-issue, but the missing parameter and VOXL_ESC_FUNC unconfigured parameters were. Thanks for the help.
One thing that is worrisome is that the chip on the bottom of the board is searing hot and must be cooled.
v/r,
Julius Marshall
