Hello.
I have a problem with my ArduPilotMega.
It worked fine. I have been uploading sketches on it many times before it suddenly got out of order.
Anytime I try to upload a new sketch to my APM board using Arduino IDE I get the following error :
"avrdude: stk500_2_ReceiveMessage(): timeout"
TX sometimes flashes while RX do not blinks at all.
We tried to upload a sketch upon APM using several computers with different operation systems via different USB cables but all the attempts failed. I think it is something wrong with APM.
What should I do in this situation?
