Hello, I am using windows 10 and have 2 separate APM2.6

I can update and have loaded firmware ver 3.2, and everything goes fine until I get to the compass calibration, and than nothing. NO dots, no movement on the screen at all.

Any suggestions?

are you using an external mag? the 2.6 doesn't have an onboard mag.

Ublox NEO-6M Core GPS Module with Built-in compass.

Check your cabling. I had this once and had a badly terminated cable. Replaced the cable and good to go.

do you have a link to the exact module? If it is a newer module then I would need to see how the i2c is wired. The older modules had a GPS lead that did 5v/TX/RX/NEG and the Mag Did 3.3v/SDA/SCL/NEG. the newer modules do not power the Mag and it's done onboard. But it is possible that they reversed the SDA/SCL leads.

Normally I'd hook up the mag to an arduino to see that it is in fact working.

Thanks to everyone, looks like a bad GPS module and a bad termination.

I was very lost, strange that I would have 2 different problems with the same outcome.

Oh well, such is life. Thanks again!!!!

I wonder if my 2 units are clones?

I should look into purchasing the newest pixhawk .

From what I have read 3DR is now out of stock and will not have any more made. The good news is I have bought some of the 2.4.8 boards on Ebay that do not have the 1 mb flash issue and they have worked fine. The plus is they only cost about 65 bucks shipped :)

OK, I need your help again, 'Ole Wizards' of  DIY DRONES.

Check out the Video. First all props spun up together 4 times.

They all start together, but as soon as I give a little throttle some motors make a noise and stop (stall and squeak). Than the next time they all start together, but now different motors stall and squeak!
