Please indulge me with a beginner's question:
About a month ago I began working with a Navio2 and Mission planner. I downloaded and installed the software obtained from a link at the Emlid site for the Navio2. It resulted in me having ArduCopter-quad 3.4.4, as I could see that displayed on the top line of Mission Planner.
How do I upgrade to this 3.4.5 release, or any new release for that matter? I found what I think may be this 3.4.5 release on the ArduCopter site - the file was named: arducopter-quad.
On the Raspberry Pi the ArduCopter-quad software is located in the directory: /opt/apm/bin/
I placed the new 3.4.5 file in there. I made a copy of the existing file (presumably the 3.4.4 file). Then I adjusted the name of the new file to have upper-case letters where the other existing one had them and rebooted.
The Pi/Navio2 seemed to come up ok on the new release. Is that how to do it? Please advise.
