What receiver are you using on your rover?
I use a normal receiver with PPM encoder.
Actually,I use APMRover on a dual motor boat.I think it can work like a skid steering rover.When I had uploaded the mission first time it worked.Then I switched to Manual and I haven't able to return to Auto since.Except Auto becomes RTL ,other modes are effectual.
Could you provide a copy of your dataflash log file when you go into auto and the vehicle RTLs?
Thanks a lot !! My log file is too large to upload. I intercept a section of it. I will send an e-mail to you if you need.
Make sure you Restart the mission each time you run it.
Your mission is unusual. Your second mission item is a takeoff command. Your in a rover right? Then you have a bunch of spline waypoints which rover will also ignore followed by an RTL command. I suspect Rover is ignoring all the other waypoints and the first thing its doing is an RTL as its the first one it understands.
I have attached your mission so you can confirm.
