I bought a Pixhawk from someone on a popular RC forum. After flashing it to 3.3 the other day, I am getting notices when connecting it that it is not authentic hardware and does not have a valid Certificate of Authenticity. I was a little suspicious because the GPS it came with is not in a 3DR case (Neo M7N I believe) but figured whomever built the quad it was on opted for a different GPS.
Is this just a symptom of the upgrade and nothing to worry about or is my Pixhawk fake? Comparing to pictures I find on the Internet, it looks fine to me. Is there a way to determine if it is legitimate or not through software?
