How to update the Arduplane firmware on Navio2

You cannot do that with Mission Planner.

Here is a link to “my” way to do that. It is not the official way (Wiki) but, IMHO, an easier one, as you continue to use the arduplane service (no need to kill it and create an ardupilot one):

Link to firmware is http://firmware.ardupilot.org/Plane/stable/navio2/arduplane

You have to change it in the command line… No change for the other commands. There are some additional commands in order to check the work in progress.
