My Arduino Mega 2560 had been working for a while. Then tonight, I received the error in the subject when using the Arduino IDE to upload a minor change to the sketch I was working on.

I've researched this a bit, but many posts are about working with a bootloader; that is not the case here. I was uploading a sketch that had been uploaded many times before.

I thought it was the USB port on my laptop, so I tried another one. It worked once, then the error returned. I tried another sketch, but the error still appeared. I tried a simple sketch (Blink) and it uploaded successfully.

I'm at my wits end? Any ideas?

Here is the verbose upload from one attempt:

avrdude done.  Thank you.


Additional information: I can upload the same program to an Arduino UNO without error. But when uploading it to the Arduino Mega 2560, I get the content mismatch error.

I tried to upgrade the IDE v1.6.6 (on 11/20) from 1.6.1, which caused another problem! All my libraries were marked as invalid.

So I punted back to 1.6.5, and it has been working fine.
