I am able to arm the Pixhawk both through telemetry and transmitter - the diode is solid green and pre arm check is successful. Unfortunately motors do not respond to throttle and do not spin at…Continue

@mark sahf

It's best not to use the group message to ask questions. Instead use the "Add a Discussion" link above.

To help you get started, first start by Downloading your Data-Flash logs as described here. Once you have done that start a new discussion describing your problem and attach the Data-Flash log you downloaded from your last flight.

This is really a necessary step whenever you are asking "why" or "how" something happened. Without the log files it's just educated guessing.

Good luck!

I did the same, bought genuine, but that didn't help when my Pixhawk failed on its 1st anniversary, for no reason.
And 3DR customer service was not of any help in that case.
Could have bought a Chinese clone as well.
I want to support those who innovate and invest to improve the open source product and soft.
So I'm buying an Arsov AUAV-X2.
Not 3DR.

Exactly! Me too

I just want to let you guys know,I purchased my Pixhawk from 3Drrobotics because

of the excellent customer service and support.You will not get that from the chinese

clones.Just sayin.

Im using Pixhawk via Sbus on my aeroquad drone.Works flawlessly with the PID's

in stock settings.Also I'm using a taranis radio in D16 mode.

Maybe you should create a sub-thread for this discussion?

Did you try forcing a firmware upload/update onto the PX4IO? For the FMU/IO stack this was achieved by holding down the arming button while powering up and keep holding it through several sequences of musical chimes. If when they integrated the IO and FMU boards into one they kept the software framework in the HAL, this may still work to reset the IO portion of the board. I'm sure one of the HAL devs could clarify this though.

Thanks Tim, a few cards were tried but no luck. There was an error message on the card that stated PX4IO board not found. So I'm suspecting a hardware failure but would like to know the cause.

Two things to try if you believe it to be an SD card fault: 1) format the SD card in a PC first (this will usually get rid of any corruptions in the file table); and/or 2) jiggle it after inserting and make sure its bedded down against the pins. I know this sounds stupid, but I had this problem last week. I tried for 3 straight hours to get two different SD cards to work and then I finally got to the point of checking if it was seating properly... and found that even when it's all the way in, it doesn't actually make good contact between the pins.

Thanks Wy, have tried multiple SD cards but to no avail. \:
