Hi,
There is a Fedora 19 image for the Beaglebone Black at http://parasense.fedorapeople.org, but I'm not sure how to use it. When copied to an SD card it boots into the MATE desktop OK, as the user "guest". However, root seems to have a password, which I can't find documented, so I can't much further than just doodling with things.
Regards, Steve
