Hi everyone,
I need your help please, I'm afraid my Pixhawk is dying (which would be a shame since it's not even 1 year old). It's doing this:
Pixhawk anniversary from mterzian on Vimeo.
- I powered my Pixhawk for a flight today and couldn't start it. The main LED (I/O) is not blinking at all any more.
- I tried to reboot several times with no luck.
- I tried to connect to APM planner via 3DR radio and the buzzer was making a very strange sound (see/hear video)
- I tried to connect via USB to reinstall arducopter but it could'nt connect to APM Planner anymore. I got an error message: "pixhawk error opening port no such file or directory"
- I tried the reset buttons on the side of the Pixhawk - nothing
- I reformatted the SD card - nothing
WIthout the 3DR radio plugged, all I can hear is the ESCs beeping.
With the 3DR radio plugged, the buzzer is screaming.
Everything was working perfectly last night when I reconfigured the RC and loaded the auto mission.
I didn't change anything, nothing happened.
Please can anyone help me understand what is going on?
Thank you!
Mathieu

Does the fault regulator destroy any other part or is it possible to desolder it and use external supply?

Hope you'll get a replacement board soon.
But get prepared to spend time chatting with HK support.
I lost a lot of time with HK (for a lost package) but eventually got a solution offered.
Good luck!
And in the meantime you can do like me: install a naze32 or CC3D in lieu of the Pixhawk ;)
Cheers,
Mathieu
I have the acro version (the same I use on my QAV250).
The acro naze32 doesn't have the barometer, nor the compass (compared to the full naze32).
So it's either manual mode (rate) or self-leveled ;-)
But it's small, simple and fun!
I'm sure you'll have tons of fun with it!
And a backup is always good.
Plus, if you were to build another quad, say a 250 for instance ;) you'll have the FC for it!
Tons of valuable information here

Hello Ivan,
Little update: I tried to reload the firmware from the SD card.
Powered the PIxhawk on while pushing the safety switch... nothing.
This time I'm really done with it.
Regarding the component on the board, here is a picture I took.
It reads reads WSS 326 on it but I couldn't see no pins.
Thank you for the information and updates Ivan!
I didn't have time to try the firmware flashing procedure you sent.
I rather had fun flying my QAV250 with naze32. It's simple (well, simpler) and it flies and it's fun!
But for some other purposes (aerial videos and photography), a more complex setup is required :)
I will look at my Pixhawk tonight to see if the component you point is the same in the genuine 3DR board.
Sorry to read that Ivan.
Seems that genuine board just last longer than clones - and are more expensive - but are subject to the same failures in the end.
The technical support from 3DR didn't help much, couldn't find a solution and didn't explain me what the cause was.
Only thing I heard was: get a new one - which I wont (not from 3DR at least).
How did you try to reflash the firmware from the SD card?
I may try this but I'm not sure how to proceed.
Good luck!
Best,
Mathieu
Thanks a lot Ivan,
I'll try this, even though I have no hope at all :)
I really hope your reseller will offer you a replacement board since you are not to blame.
And your are VERY right: in a way, we're lucky our multi never took off with a faulty FC.
As for me, I'm only sure about one thing: I won't buy any 3DR product again.
Not sure about APM: it seems arducopter 3.2 is better suited for Pixhawk or equivalent processing power.
So I may try VRbrain but I've stumbled upon AUAV-X2 and I really like it. As long as I can order one (seems always backordered).
Cheers, and good luck with the reseller!

Right now I have no idea what happened. You may want to move your post over to
'PX4 and Pixhawk Hardware." You may get the some better response there.
Goodluck
