This is the wiki page for the Linux4nano project. Here is the project homepage, and here is a link to the project's mailing list. Linux4nano also has a fairly active IRC channel, #linux4nano @ irc.freenode.net. #linux4nano-dev is the channel for developers. IRC logs are located here (password protected). Info about this wiki can be found at the About page.
NOTICE: Anyone who has landed here thinking that Linux is running on the new Nanos, you are wrong! Some ignorant Hackaday author has started this rumor.
