Renesas Announces R-Mobile A1 Application Processors

Renesas has unveiled R-Mobile A1 series of application processor for personal navigation device (PND) and other portable devices. Here’s an excerpt of the press release: Renesas Electronics Corporation, a premier provider of advanced semiconductor solutions, and its subsidiary, Renesas Mobile Corporation, an innovative supplier of advanced cellular semiconductor solutions and platforms, today announced the R-Mobile A1 series of application processor for PND (personal navigation device) and other portable devices. The R-Mobile A1 series of devices integrate Renesas’ SH-Mobile R series and EMMA Mobile™ series, which have proven track records as application processors for PND and portable media players … Although equipment that includes ISDB-T one-segment broadcast reception functionality has become mainstream in portable equipment such as PNDs and portable media players, there are now increasing needs for higher image quality and higher functionality due to the widespread adoption of ISDB-T full-segment terrestrial digital TV broadcasting. Furthermore, there are increasing demands […]

DLNA/UPnP Linux Server with Coherence

Coherence is a DLNA/UPnP Media Server written in Python which exports local files or online media to UPnP clients. Coherence fetch the media files from several sources such as: Local applications media collections, like those from Rythmbox or Banschee, Audio-CD or DVB Online services like Flickr, last.fm, YouTube, Picasa Web Albums and other. Other sources can also be added thanks to Coherence plug-in architecture. The media server supports transcoding (currently experimental) that is to convert media files in another format. Coherence toolkit also contains other packages such as: Coherence-Config: a cross-platform GUI frontend for ‘Coherence’. Cadre: a picture DLNA/UPnP MediaRenderer which can display pictures from the local filesystem or from a MediaServer. Mirabeau: An application level proxy for UPnP devices which allows to share your UPnP content between two or more local networks over the Internet. It uses XMPP as a transport (work in progress). UPnP-Inspector: a graphical UPnP Device […]

Using Buildroot For a Real Project – ELCE 2011

Thomas Petazzoni, embedded Linux engineer and trainer at Free Electrons, shows how they used buildroot for a specific project at Embedded Linux Conference Europe 2011. Abstract: Buildroot is a nice, simple and efficient tool to build small to medium sized embedded Linux systems, such as the ones found in many industrial systems or highly dedicated systems. Buildroot allows to automate the process of building a cross-compiling toolchain, building the root filesystem with all userspace components, building a Linux kernel image and a bootloader image. Based on experiences of a specific customer project, Thomas details how Buildroot can be configured and used to quickly produce nice, fast and efficient embedded Linux systems, but also how the target application development and debugging can be done based on Buildroot.

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.

ARM Linux Kernel Alignment & Benefits For Snowball – ELCE 2011

Andrea Gallo, Chief Linux Architect in the Smartphone and Tablet Solution organization in ST-Ericsson and part of the Linaro Technical Steering Committee, explains how a common Linux ARM kernel benefits ST Ericsson Snowball development platform. Abstract: Last March, the ARM Linux community got shaken by the complaints by Linus Torvalds for its lack of proper structure and organization. This is totally true and mainly due to the large number of different SoC vendors, each one integrating the ARM IP’s in a slightly different variant. Linaro immediately accepted the challenge to drive the kernel alignment of the ARM community and most ARM Linux experts got together and agreed on the way forward as early as May 2011 at the Developers’ summit in Budapest. ST-Ericsson is a founding member of Linaro and some key ST-Ericsson engineers are assigned to Linaro and specifically to this kernel alignment working force. In the speech, Andrea […]

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.
