Colin: I don't think so. I suspect it's just a board that's gone bad for some reason. I'm not seeing any issues with other boards. Might as well send yours back to 3DR to be checked out.

Hei Colin

I have exact same problem, but with my APM v1 board.

With USB cable conneted i get a fix, but powering the board with battery/esc i don't get a fix.

That probably means either your battery needs to be charged or your ESC isn't putting out enough power. Charge the battery and/or try a different ESC

Sounds like you've got a broken trace/connector somewhere. Does the blue LED come on on the GPS module itself?

Yes, its blinking and satcount is mostly 2-3, gpstatus 1, gpshdop 9999 while indoors. But as soon as i remove battery power and connect usb i get lock and satcount goes up to 11 within 1min.

UPDATE

 

HI, the problem is still here.

After a day of configuration I've again the same problem, when I power on the board only Blue LED ON.

 

In debug windows It STOP load on: INIT GYRO.

 

After that message the board do not output any message. If I Press reset button, the board boot fine and work.

I've tried:

Arduplane 2.28 firmware

Arducopter 2.4.1 firmaware

 

Any idea? Defective Board?

MarkO: Try leaving it for a few minutes--it may just be autoerasing the dataflash. If it doesn't eventually boot correctly (and then operate correctly from then on), contact customer support for a RMA.

Hi MarkO,

 

try to load the firmware from Arduino instead MP, for me has worked. (sometimes...)

It is a very strange problem.

Hi friends!
I have a problem with the startup of my AMP2, watch the video below it is a problem similar to

yours or a problem of BEC / UBEC because my engine only works when I turn my APM2 before

connecting it to the USB.

Please help me to fix this problem! I cordially thank
