"what do you mean that the pixhawk restarted?  Did you hear the startup noises again?  Did you unhook the faulty ESC's and try to calibrate, arm, and run the one good working ESC/motor?  Also, what kind of noises / LED flashing did you get from the…"

"Hi Joe,
I've been able to interface my ardupilot with several computers, I've never ran into one which wouldn't work (obviously as long as ardupilot was functioning correctly). 

I have interfaced with the ardupilot with an acer aspire one laptop…"

"It turns out that the voltage regulator off the battery I was using was dead and giving my board double the voltage it required...after checking F1 and F2 fuses, the zener diode, and the onboard 3v voltage regulator (which all checked out), and then…"

"Hi Javier,

I had the same thing happen to me with my pixhawk.  I had to push the safety button down every time within a few seconds of startup or else it wouldn't work.  

Good luck

"I know this is late...but just for reference for people with the same problem.  I had trouble calibrating my ESC's and getting the props to spin up at arming.  HERE IS THE SOLUTION (thank you gregmaan)

"The PM that I was using that fried it was a 3DR PM that was about a year old.  When I tested it was putting out about 10 V but by that time it was too late.  I replaced it and am getting the correct PM 5V output but the APM is dead.

I contacted 3DR…"

"For clarification, have not been using JP1, only was powering through battery (XT-60 connectors), or USB (always seperately, never USB and battery at the same time).

I've downloaded the schematic and opened it using Eagle.  F2 and F1 have…"

"Are there any places on the board that I can check voltage to rule out hardware failure?"

"I searched through your posts to find the info on the sonar setup but was unable to locate it.

I have an APM 2.6 with a quadcopter setup and I am trying to do some basic obstacle avoidance such as turning a pre-planned direction once an obstacle is…"

"Yeah I wish I had some.  Was looking at buying some last night but they aren't cheap!  It may be worth it for the future though."

"I got my new 3DR magnetometer and hooked it up and it didn't work!  Then I realized that I had wires the 4 pin molex connecter exactly BACKWARDS!

Some quick soldering fixed the problem.  But it will take more than that to fix my broken ego!!! haha!…"

"Thanks for your reply Para.  I double-checked the wiring (SCL, SDA, power, ground) just to be sure everything was connected properly (per the link I shared below).  I also tried it with different orientations but it seemed to give me the same error.…"
