My guess. And it is a guess. 3.5 introduces major changes with how frame types are handled. Likely still needs work on Navio. I am sure one of the Emlid guys will chime in here. Glad you were able to abort without damage.
Thanks for testing it out. We’ll try it out tomorrow.
First guess, have erased old parameters from AC-3.4.4? AC-3.5 will incorporate a lot of changes and I suppose that something might be a little awry now (it’s now almost aligned with the latest master branch which in discouraged to fly off).
Could you describe how did you launch the newest AC? I hope you’ve gone through the beta-docs and launched it like described in here!
As there is some ?? about the change, I redid the settings (latest Mission Planner ß), reset to defaults (3.5 rc1) and redid the configuration (frame choice, calibrations, and also ESC calibration). Esc are OK at the end of calibration but next boot with battery give same problem (erratic motor activity). RC out stay at low -no variation but motors are running…
Now, power module is dead, (only 2.7 volt out…) so no boot (no more problem)
Pi config and Arducopter settings are by the book,
i didn’t try 3.5rc1;
but after resetting parameters in missionplanner and then rebooting pwm out is at 1100 and my motors spin too - until i calibrate my transmitter (if i remember correctly);
not sure if this is related to your problem (actually i don’t really think so)
@george.staroselskiy What can I help test? I finally had time to build another copter we can keep around the shop for testing/crashing. Right now we are running latest beta and it’s working well. If you can let us know about when next beta will drop I can plan a bit better to help test.
