Topic: Arduino DUE: problem uploading sketch to the board (Read 764 times) previous topic - next topic


 I am having troubles uploading a sketch on my Arduino DUE board; in fact it can't actually upload any sketch, no matter what is written on it, so it obviously not a sketch problem.
Some time ago I succesfully interfaced Arduino and Processing, just to graph data Arduino sent to serial port.

Now whenever I try to upload a sketch on my board (both with processing open AND closed) the following error appears.
I have no idea what to do.

Thanks in advance

Hello, I just would like to make sure I understand, that you have loaded a sketch to the DUE in the past and now can no longer load.  Or is it you have never been able to load a Sketch?


I have been succesfully using Arduino for the past 9 months, just after using processing it started to have these troubles.


Hey did you ever get this figured out? 

I am using a Due for the first time and am not able to upload and get the same error message as you do.  I can remove the Due from the USB port connect an Uno and it uploads via the same port no problem???
