timeout while uploading sketch to APM2

Posted by flyer on August 2, 2012 at 1:43am

Hi everybody,

I am trying to upload the ArduCopter 2.7.1 to my APM but the Arduino gives me errors:
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout

I have the 250 board and I tried it with the relax patch the latest arduino version. Nothing works. I uploaded a code 2 weeks ago and it worked fine, but now it doesn't. Why?

Do you have any suggestions?

I am getting crazy with this issue...

Thanks!

Hi,

had similar problems with a different Arduino board some months back. Google the error message and you'll find that there is a large number of causes and potential fixes. The way I got it finally solved was (I have no clue why this worked) with a different (actually older arduino version), after which uploading again worked with the newer one. Sorry, can't give an explanation and yeah it sounds odd.

Good luck,

Andre
