LinuxCon North America 2012 Schedule

LinuxCon (North America) 2012 will take place on August 29 – 31, 2012 at Sheraton Hotel & Marina, in San Diego, California. The event will be co-located with the Linux Kernel Summit, the Linux Plumbers Conference, and CloudOpen 2012. LinuxCon consists of 3 days of keynotes, business and developers related sessions as well as tutorials. There will be over 80 sessions and keynotes during those 3 days. I’ll highlight a few sessions that I find particularly interesting and related to embedded Linux, software development and ARM. August 29 10:45 – 11:30 – Life After BerkeleyDB: OpenLDAP’s Memory-Mapped Database by Howard Chu, Symas Abstract: OpenLDAP’s new MDB library is a highly optimized B+tree implementation that is orders of magnitude faster and more efficient than everything else in the software world. Reads scale perfectly linearly across arbitrarily many CPUs with no bottlenecks, and data is returned with zero memcpy’s. Writes are on […]

Gumstix TurtleCore Expansion Board for iRobot Create

Last month, Gumstix announced the TurtleCore expansion board for iRobot Create Programmable Robot, featuring 3 USB ports, several male-header pins with GPIO access, as well as standoffs and screws to support the TurtleCore in the Create cargo bay.. The TurtleCore is a baseboard for TI OMAP3 and Sitara based Overo COMs or Overo STORM series of COMs that replaces the Command Module on iRobot Create to provide a more flexible and powerful solution. Overo COMs have very good Linux support (OpenEmbedded) with source code, tools and documentation available, including support for the Robot Operating System (GumROS) for high level programming. They released the hardware early so that the community could work on the software, and there have been some good progress as you can see from the video below. You can already download the schematics and PCB layout file, but the software and instructions do not appear to be available […]

The Yocto Project Overview and Update – ELC 2012

Saul Wold, User Space Architect at Intel Open Source Technology Center, discusses the latest on the Yocto Project at the Embedded Linux Conference 2012. Abstract: The Yocto Project is a joint project to unify the world’s efforts around embedded Linux and to make Linux the best choice for embedded designs. The Yocto Project is an open source starting point for embedded Linux development which contains tools, templates, methods and actual working code to get started with an embedded device project. In addition, the Yocto Project includes Eclipse plug-ins to assist the developer. This talk gives a walk-through of the key parts of the Yocto Project for developing embedded Linux projects. In addition, features will be described from the latest release of Yocto. At the end of the talk, developers should be able to start their own embedded project using the Yocto Project and use it for developing the next great […]

Yocto Project Release 1.1 Announced

The Linux foundation announced Yocto Project Release 1.1 today. This release codenamed “Edison” and based on Poky 6.0 is the the second release of the project, one year after it was announced in October 2010 to provide developers with greater consistency in the software and tools they’re using across multiple architectures for embedded Linux development. The Yocto Project reached the following milestones during the last year: Alignment of OpenEmbedded technology and the inclusion of OpenEmbedded representation in the Yocto Project governance structure. The projects share a common core that consists of software build recipes and core Linux components that prevent fragmentation and reinforce the OpenEmbedded methodology as an open standard for embedded Linux build systems. Contribution of tools and technologies such as Cross-prelink, EGLIBC, Pseudo, Shoeleather Lab (for automated testing) and Swabber have been contributed from Intel, Mentor Graphics, MontaVista Software and Wind River. Commercial adoption with examples such as […]
