I use the Intel IoT ADK Linux image, built from the instructions on intel's IoT site.
And there's various other builds being mentioned from time to time in this forum, but I find it hard to follow which is which.
Does anyone have a round-up of the various Linux images available for Galileo?
It's beyond me, but I think it would be good if someone could do a list of them, with their major features such as: base build; whether devtools are included; does it run sketches; and so on.
