This is the official BeagleBoard-X15 discussion list. Archives are visible to the public, but discussion is limited to select developers at this stage. If you feel you would make a significant contribution to open source software around this board and haven’t been invited, contact me via jkridner on beagle on http://irc.freenode.net to request an invite and be specific and concise about what you’d contribute.
