Could someone PLEASE explain this one to me!
I plug the APM in, boot goes as normal, but green led stays on. Nothing will work except CLI.
I then touch the 6 pin connector (the one going from the red board to the blue) (AVR-ISP) see attached picture.
Then everything works fine.
Why on earth is this???
Iv attached a picture of the pins i touch to get it to work.
Heres a link to a video of the whole process: http://www.youtube.com/watch?v=sgMyoabBIgA
P.S. I dont have to touch all the pins, if i just touch the top left one (as seen in attached picture),
then it works...
If i only have to touch one pin would it not suggest a grounding problem?
Help me guys!!! :))))))
That top left pin is ground. Methinks you have a bad solder joint causing noise on the board. Please retouch your solder joints on those pins.
Hi Jason, thanks for the reply.
The first thing i did after discovering the problem, was re-solder all 12 joints & check continuity.
It made no difference.
I dont think its a grounding problem either, if i bridge ground to the pin from either the USB connector or even the telemetry connecter, nothing happens. Only when i touch the pin with my finger does it work...
What do you think the problem is? Faulty cap or ic?
