[Ovmsdev] OVMS v3 getting started

[Mark Webb-Johnson]

Presumably the final ‘make monitor’ was ok?

If so, then that worked perfectly for you.

Perhaps leave the drivers and environment as it is, and then repeat the test when you get OVMS v3. That will confirm that it is not our problem (but a general OSX/driver issue, presumably with some versions/combination/port).

Thanks, Mark
