I''m studying AMP these days, and a lot of problem appeared. I download the FilghtGear and APM Planner 1.1.33 and start to simulation. Follow the wiki, I don't know clearly about HIL firmware, what does this mean? In the firmware tab, I can do nothing, click the image and fail, I don't know why and which firmware is HIL, so I can't ensure what firmware is being used.like this:

Second, working with FlightGear, I've created the bat file, and reset the lines "C:\Program Files (x86)\FlightGear\bin\Win32\fgfs" ^ "--fg-root=C:\Program Files (x86)\FlightGear\data" ^ to my FlightGear 2.4.0 files.In the APM Planner, set udp and 49005,but also could not connect, it tells me like below:

In the terminal, "Error reading com port" is showed

can anyone could help me about the error,.Thanks a lot.
