I have just put my Ardupilot Mega (ATMega2560) and now I am attempting to upload the firmware. I have tried to use mission planner 1.1.22 and when i select arducopter for quad it comes up with an error saying " Failed to download new firmware:System.IO.IOException:The port "COM18" does not exist."
I have also tried arduino and it has given me errors when trying to compile saying "AP_int16" does not name a type
Could someone PLEASE help!? I just want to fly my quad and everything just seems to not work so far.

I had the same problem, after a couple of tries i got mission planner to work.
I got very frustrated with mission planner and tried compiling the code in Arduino IDE 1.0 in Linux and got the same error as you.
What are we doing wrong?

After Try to compile again.
