ArduCopter HIL

Hey guys,

Can anyone give me a hand with HIL for ArduCopter?

I’ve read on the wiki (youtube.com/watch?v=sXbOl2HOUPY) where HIL worked for ArduCopter 3.2.1.

I’ve tried different versions of ArduCopter but I’ve had no luck. I’m trying to work out how to get and test ArduCopter 2.8 as well. I need to get ArduCopter 3.2.1 working because the group that I am working with cannot use a different version.

The problem is that the GPS keeps flickering on and off. This can be seen in Mission Planner and ArduCopter goes into a failsafe mode after taking off.

I’ve documented what I tried and hopefully this can help someone else.

I am a software developer so if the fix requires looking at code, please let me know where to start looking.

Thanks!
