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 development. Audience would be embedded developers who are interested in …

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.

Android Platform Optimizations – ELCE 2011

Ruud Derwig and Mischa Jonker, both working at Synopsys, present different Android optimization methods at Embedded Linux Conference Europe 2011. Abstract: Although compute platforms gain performance with every new generation, getting the most out of every cycle and milliwatt remains a key value driver for Consumer Electronics. This presentation opens up the Android platform and explain what platform components and frameworks can benefit from performance optimizations. The optimizations are illustrated using real-life examples from the porting and optimization of the Android platform for the DesignWare ARC CPU. Both Android platform and application developers will gain insight in how to improve Android performance. Topics that are addressed include the Pixelflinger, Linux kernel and drivers, Javascript engine, Bionic C library, and the Dalvik VM. We’ll demonstrate the portability of Android and suitability of the ARC architecture for building efficiently Android systems. You can also download the presentation slides.

Embedded Linux Optimization Techniques – ELCE 2011

Benjamin Zores, Alcatel-Lucent, describes different optimization techniques (focusing on hardware choice and software architecture) that can be used to improve the performance of embedded linux at Embedded Linux Conference Europe 2011. Abstract: This presentation provides a series of techniques that can be used for Linux embedded systems fine-grain tuning and performances optimization. Embedded systems are, by definition, always limited in terms of resources while people keep on trying to use desktop-oriented software on top of it. This talk presents a series of tips that can be used to actually measure, find and isolate bottlenecks in your system, whether it is by complete system profiling or software architecture optimization. Focus is also made on the traditional caveats that need to be avoided for your system not to be slow by design. You can also download the presentation slides.

Developing Embedded Linux Devices Using the Yocto Project – ELCE 2011

Presentation entitled “Developing Embedded Linux Devices Using the Yocto Project and What’s new in 1.1” by David Stewart, Intel, at Embedded Linux Conference Europe 2011. 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 are described from the latest release of Yocto (1.1). 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 embedded device.

The Linux NFC Subsystem – ELCE 2011

Lauro Ramos Venancio, Instituto Nokia de Tecnologia and Samuel Ortiz, Intel give a presentation about the NFC subsystem in Linux at Embedded Linux Conference Europe 2011. Abstract: NFC (Near Field Communication) is a wireless protocol mostly designed for fast information reading and writing from nearby devices and tags. It also allows NFC devices to establish a transport layer link and exchange larger chunks of data. While Android ships with its own multi platform NFC stack writing HCI frames to a raw character device and supporting one single device, Linux is currently missing any kind of generic and clean NFC support, from both kernel and user space (cnxsoft: Since end of last month, this is not the case as Linux 3.1 supports NFC). Therefore, a new socket family for NFC, along with a kernel netlink API for high level NFC commands passing is being developed. An NFC user space daemon abstracts those kernel APIs into a high level D-Bus API for …

Board Bringup: LCD and Display Interfaces – ELCE 2011

Presentation “Board Bringup: LCD and Display Interfaces” by David Anders, Texas Instruments, at Embedded Linux Conference Europe 2011. Board bringup is one of the most under documented aspects of embedded development. This presentation looked at the various display technologies such as DisplayPort, DVI, LVDS, and other LCD interfacing methods with emphasis on how to bringup, debug, and validate them on new hardware. Using a case study, aspects such as interfacing timing, extended display identification data(EDID), and backlight controls have been discussed. Most embedded linux developers at some point in their career will be handed a piece of hardware that is untested. LCD bringup is one of the most challenging assignments for an embedded developer. This presentation intends to provide some core tools and methods for bringup of a new display interface. You can also download the presentation slides
