Linaro’s Android Platform – ELCE 2011

Zach Pfeffer, Linaro Android Platform team leader, describes Linaro’s work on the Android platform and future plans at Embedded Linux Conference Europe 2011. Abstract: Linaro uses components from the Android Open Source Project, member companies, community supported efforts and Linaro engineering teams to build integrated, easy-to-use and well tested Android platforms for upstream work, product baselines and hobby projects. The team currently has platforms for TIs PandaBoard, BeagleBoard and Beagle xM, ST Ericsson’s Snowball, Samsung’s Origen and Freescale’s iMX53. They recently released platforms with Android 2.3.4 built against GCC 4.6 and running the 3.0 Linux kernel. In this session Zach reviews what’s been done, the Linaro Android concept, how Linaro brings Android together and what their plans are.

Device Tree Status Report – ELCE 2011

Grant Likely, owner at Secret Lab Technology, describe the current status of device tree (used to resolve ARM “hodgepodge” issue) and provides an example at Embedded Linux Conference Europe 2011. Abstract: In recent years, Linux has enjoyed immense success in the embedded market, and we’ve seen an explosion in the number of devices supported by the mainline Linux kernel. Traditionally, however, adding support for another embedded machine typically involved adding yet another board.c file to the kernel which more often than not was simply cut and paste from a similar board. As a result, board support code contains a huge amount of duplication and has become so huge that it is becoming unmaintainable. To move away from individual board files, several architectures have adopted the Device Tree method of encoding the hardware details into a data structure which can be parsed by generic initialization code and device drivers. This session […]

Tuning Linux For Embedded Systems – ELCE 2011

Darren Hart, Intel’s Open Source Technology Center, gives a 5 step method to optimize Linux (image size, memory footprint and boot time) for embedded systems at Embedded Linux Conference Europe 2011. Abstract: Although embedded systems are less and less resource constrained, there is still a lot of demand for minimizing the image size, runtime memory usage, and boot time. The firmware, kernel configuration, hardware initialization, boot-time arguments, start-up scripts, and library sizes are all examples of things with a direct impact on your image size and/or boot time. There are several core processes involved with minimizing the size of an image, which has a direct impact on runtime memory usage and boot time. The focus is on configuration techniques that get you most of the way there and follow-up with source-level customizations that get you the rest of the way.

Booting Userspace in Less Than 1 Second with Systemd – ELCE 2011

Koen Kooi, the lead developer of the Angstrom distribution, introduces systemd (sysvinit replacement) and shows how it can be integrated to a specific platform at Embedded Linux Conference Europe 2011. Abstract: Systemd is currently being hyped as *the* sysvinit replacement and this presentation will show why it’s here to stay. A brief introduction to systemd is given but the main focus is on showing how to integrate it into your favourite platform and how a few hours of tweaking can boot userspace into X11 in less than 1 second on the current generation of ARM chips (OMAP4 on Pandaboard). A comparison with slower low-end ARM chips is also be included and some design considerations when designing those low-end systems. The audience is system integrators and hobbyists that require a fast boot (e.g. robotics people). You can also download the presentation slides.

Yocto Project Community BoF – ELCE 2011

Jeff Osier-Mixon, community manager for the Yocto project and working at Intel, presents the Yocto Project at Embedded Linux Conference Europe 2011. Abstract: The Yocto Project is an open source collaboration project that provides templates, tools and methods to help you create custom Linux-based systems for embedded products regardless of the hardware architecture. This BoF (Birds of a Feather) provides a meeting place for members of the Yocto Project community to gather, meet Yocto Project developers, see hands-on demonstrations, and get answers to questions about using the tools. The audience for this BoF includes embedded Linux developers, application developers, and systems integrators who are looking for an industry-standard approach to building custom embedded Linux distributions, at all expertise levels from newly-hatched developer to grizzled professional. Attendees can expect to learn the latest about the Yocto Project and to learn how they can participate and benefit.

The Yocto Project Eclipse Plug-In – ELCE 2011

Jessica Zhang is Software Engineer at Intel and works on Yocto Application Development Kit (ADT) and its Eclipse plug-in. She presented Yocto Project Eclipse Plug-in at Embedded Linux Conference Europe 2011. Abstract: Yocto project is an open source collaboration project that aims at helping embedded Linux software developers, either for system or application development. The Yocto Eclipse plug-in provides an effective integrated development environment that is based on the widely adopted Eclipse CDT and TCF extensions. It allows user to seamlessly interact with various Yocto project development tools. Yocto 1.0 targeted application developers via cross toolchains and sysroot setup, with remote deploy, debug and analysis. For 1.1, we have added support in the Yocto Eclipse plug-ins for system development through interaction with the bitbake UI interface for a Yocto bitbake commander type project. This talk will demo the end-to-end usage flows of Yocto Eclipse plug-in for both system and application […]

Optimizations for Cheap Flash Media – ELCE 2011

Arnd Bergmann, Linaro (and IBM), explains how NAND flash access can be improved in Linux embedded systems at Embedded Linux Conference Europe 2011. Abstract: Mass storage in embedded systems typically means NAND flash in the form of eMMC, SDHC or similar technologies. Unlike server-class SSDs, these have few optimizations that help reduce write-amplification. This presentation explains the typical shortcomings in this design and how system builders and software developers together can avoid them, in order to get longer life and better performance out of low-end media. You can also download the presentation slides.
