I have been using pixhawk succesfully for a week now BUT...
today after a small flight indoors ... after i dissarmed my quad i couldn't arm it again from safe button.
I didn't have the buzzer on so i had no indication of the problem. So i decided to plug my pixhawk on my pc through usb without everything (later on i connected the buzzer and safety switch) and it could not connect to apm nor mp.
After pluging the buzzer i heard this strange beep sequense that is not listed in the known ones so please if someone can help me ... it goes 3 quick beeps and then 3 long beeps like beep beep beep - beeeeeeep beeeeeep beeeeeep . The safety switch blinks fast.
If while it beeps i press the "Flight management reset button" next to USB , then pixhawk comes alive and i am able to connect to both apm and mp.
And WHY does it get OK when i press the "Flight management reset button" ?
Of course pressing the "Flight management reset button" is not a normal solution for when i am on the field , so PLEASE HELP ME !!!!

I had the same issue. With all logging options off, the pre-arm stage still was blocked on logging. And then I checked the pre-arm section and there's a logging check there. If you disable that check, you can get past the 'pre-arm: logging' failed error.

Thank you people, I just solve my nightmare here.
What is the maximum capacity for SD card in Pixhawk?
But 4 or 8Gb works as well, I guess it is related to how much PIXHAWK logging you would like to store there..
I believe the standard is 4GB if I am not mistaken..
Also I think Randy did firmware update for this problem
......"AC-3.1.4-rc1 is now the official version available through the Mission Planner.
There are no changes for APM1 and APM2 users, but for PX4/Pixhawk users there are these bug fixes:
1. Bug Fix for Pixhawk/PX4 NuttX I2C memory corruption when errors are found on I2C bus
2. Fat system file corruption bug that could lead to corrupt log files"....

@Yiannis,
The 3 short and 3 long beeps are for SOS I believe.
The Kingston micro SD cards that come with the Pixhawk have not given me any trouble on my two recent Pixhawk purchases. I have also used a SanDisk micro SD card with one of my Pixhawks without any issues.

I refer to a batch which had the PX4 logo on it, and shipped around early January this year.
Guess the PIXHAWK is now delivered with Kingston SD cards...
Not a big deal, but kind of annoying if you start with PIXHAWK, and don't have a clue why it is happening,..
Thanks for your feedback anyway !
The more I fly with my drone the more I am impressed with the PIXHAWK as controller...
I have a couple of movies on YouTube under my channel, FPVDroneEG for those who are interested...
it is a big deal!
WHO WILL PAY ME FOR NEW SD CARD?!
I DO NOT CARE IF IT IS 1 OR 2 OR 10$,that is original peace of hardware witch does not work!
and affected users are tho ones who rush to buy early Pixhawks??
also Since I erased logs from sd card and be able to arm again,now my non 3dr radio(433MhZ,rcTIMER) AIR MODULE STOP WORKING.....IS THIS NORMAL?
Ok,radio is working now after I upload settings few times with fdti cable...
It was extremely frustrating experience for me too.. I spent a lot of time trying to understand what was going on until finally contacting 3DR and waiting a few days/week for a response.. turned out they knew about the problem but failed to email me notifying me of this very frustrating known problem...
anyway, swapping out the SD card to a different quality MicroSD cards fixed it for me... and they did send replacement MicroSD cards as well...
Anyway, definitely change out your SD cards until a good replacement arrives from 3DR.... It's a shame 3DR failed to notify their customers of the problem in advance.
Ok I bought my original Pixhawk from Kopterworks who is selling them I guess as official supplier

...but no one contacted me at all...what should I do?
My Pixhawk do have 3DR PX4 logo on right side of box.....
