Welcome to Linux4SAM

Welcome to the main starting point for Linux OS on SAM products. Its aim is to centralize information about Linux kernel and open source projects on Microchip AT91 Smart ARM-based Microprocessors (aka SAM).

Our goal is to be an interface with open source projects that include AT91 support. We do not want to duplicate information but to link as much as possible to good resources available on the Web.

Keep an eye on this website as it has been designed for instant update. We will try to make it live with the open source community and update AT91 information in those pages. To keep yourself informed, add WebRss or WebAtom feeds in your usual news reader.

Questions, feedback, patches and enhancement are the way open source communities live. Go to LinksToCommunities page for a natural way to interact with material presented on this website.
