Running old Ardupilot code on cube orange

I am trying to run and old 3.8 version on cube orange, without success.
Does any body has a clue, how can i do it?

You can’t! There isn’t the required drivers and configuration in the old firmware. It will never work.
You need to use latest stable firmware anyway, there is important fixes.

Think of it like this:
You could get it to work if you include all the new drivers in the old software version and recompile it… Then you could also include all the fixes and improvements and recompile all them in…
Then you’d have the new firmware :laughing:
