Welcome to Linux4SAM

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

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.

  • Full support for EGT (version 1.0 included)
  • Moved to the new Yocto branch, Dunfell (3.1) LTS release
  • Moved to new Buildroot release, 2020.02 LTS revision 2020.02.2
  • Moved to new OpenWrt release, 19.07.2
  • Firmware version 15.4 for WILC3000 and WILC1000 Wi-Fi and Bluetooth together with all the required software components (wpa-supplicant, hostapd and more). For any questions check FAQ and Applications pages.
  • WILC demo apps are now available : Wilcbtapps and Websocket for the SAMA5D27 WLSOM1 EK board. Also included WiFi provisioning webpage.
  • Yocto Project has deprecated Python2. We made a special version of AT91Bootstrap (v3.9.3) that uses Python3 instead of Python. There are no other differences between v3.9.2 and v3.9.3. Python is used by AT91Bootstrap only as a build dependency.
  • Amazon Web Services GreenGrass (AWS GG) v1.10.1 is now included and ready to connect to AWS Cloud for all our sama5d2 based boards , on both Buildroot and Yocto Project distributions. The availability of ECC608 either as soldered on-board or as an addition through an expansion connector makes the solution secure, easy to use and seamless.

Thumbs-up Demo Image for all boards. Choose headless (no video) or graphics option, your root filesystem flavor, flash and you're ready to go:
Demo Archive 2020.04 page

  • NAND and SPI + eMMC media types were flashed using SAM-BA 3.3

Thumbs-up Yocto Project SDK based on Linux4SAM 2020.04 release (Yocto Project 3.1 Dunfell)

And all goodies of previous Linux4SAM revisions!
