Being new to the world of Arduino, I have recently came across this error message while uploading a sketch.
"averdude: verification error; content mismatch"
Woops! What did I do wrong? I ran this sketch before and it uploaded just fine. I hope my board isn't going bad so soon, I just got it. Does anyone know what this error is and how to fix and or prevent it? It seems like there are a lot of people asking this question but no solid answers.
Perhaps turning on this option in "Preferences..." and posting the resulting messages will allow someone to assist you:

This report would have more information with

option enabled in File -> Preferences.
any help available?

That is not an Arduino so there could be something wrong in the design of the hardware, the bootloader, or the third-party Arduino add-on that supports the third-party hardware and bootloader. I'd recommend going back to the manufacturer's site and following their directions step-by-step. Perhaps their add-on does not support V1.6.13 of Arduino.
