Adapting Your Network Code For IPv6 Support – ELC 2012

Mike Anderson, CTO and Chief Scientist at The PTR Group, discloses how to bring your network code up to speed for IPv6. Abstract: IPv6 support is no longer a “sometime in the future” thing. We’ve exhausted the IPv4 address space and need to start transitioning our code to support IPv6. But, is this a big thing or a little thing? This presentation will outline the typical changes that need to be made to networking code to support IPv6 and describe transition strategies to enable use in a dual-stack environment. The target audience for this presentation is developers who want to take advantage of the new IPv6 address space. This presentation is targeted at intermediate-level developers with some understanding of the IP protocol stack.

LAVA Project Update – ELC 2012

Paul Larson of Linaro gives a LAVA Project update at Embedded Linux Conference 2012. Abstract: The Linaro Automated Validation Architecture (LAVA) is an open source framework used at Linaro for running automated tests on Ubuntu and Android based images, kernels, and more. I introduced LAVA at ELC a year ago. Since that time, considerable progress has been made on the project, and many new components have been added to it. This talk will briefly re-introduce the project to those who may not have heard about it, as well as introduce the new developments. You can download the presentation slides at elinux.org.

Ubuntu on ARM: Improvements and Optimizations Done by Linaro – ELCE 2012

Ricardo Salveti de Araujo, developer platform lead for Linaro, displays the improvements Linaro have added to Ubuntu on ARM. Abstract: Since Linaro’s start, there was a need to have a supported platform for ARM, that could use the Linaro changes, to improve the ARM experience in general and to show the results of the work done by Linaro. In this session, it’ll be presented why Ubuntu was selected as the base platform for Linaro, describing the benefits and the areas Linaro is continuously investing to improve it. It’ll also be described the current state of the platform, showing some of Linaro’s achievements and also how we’re working to support the main SoC boards available, like Panda, Beagle, Origen, iMX53 and Snowball with the latest development by Ubuntu and Canonical, like Ubuntu TV, Phone and Tablet. You can also download the presentation slides. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 […]

Status of Embedded Linux – ELC 2012

Tim Bird, software engineer at Sony, discusses recent development in embedded Linux at the Embedded Linux Conference 2012. Abstract: Tim discusses changes to the kernel, improvements to embedded-related sub-systems, and new industry initiatives likely to affect embedded Linux developers in the future. Also, Tim discusses the direction of the Linux Foundation CE Workgroup, and their contract work and projects for this year. Last year highlights are also discussed, as well as ways to continue to improve Linux going forward. Here are the key points of this presentation: Linux Kernel Version changes: 2.6.38 to 3.3-rc3 Technology Areas: Bootup Time – With improvement in the kernel, bootloader and user-space Graphics – 2D/3D implementation. New /dev/ion and CMA graphics stuffs Accelerated Rendering – e.g. Renderscript Graphics Drivers – e.g. PowerVR Multimedia – Gstreamer, Android Media Layer (stagefright) and codec wars (e.g. patent issues with WebM/VP8 that interferes open source licenses). File systems – […]

Binary Blobs Attack – ELC 2012

Zach Pfeffer, Android Platform Lead at Linaro, talks about (GPU) Binary Blobs and the problems they cause at Embedded Linux Conference 2012. Abstract: Binary Blobs Attack!!! Most SoC vendors distribute binary blobs with Linux kernel shims. These binary blobs enable graphics engines, DSPs and other cores on ARM and other architecture SoCs. These binary blobs tend to be tied to specific kernel versions which limits unreadability and hackability and complicates device manufactures, which slows down innovation and the introduction of new and unique computing devices. Here’s what I noted from this presentation: Most of the issues at Linaro come from (GPU) Binary blobs, they delay projects and cause projects to cost more as FAE and more engineers must be involved in solving problems. Blobs are here to stay mostly due to legal reasons (patents). Binary Blob are usually OS independent, e.g. the same binary is used in Windows and Linux, […]

Low Cost armStoneA8 SBC Technical Specifications Released

About 2 weeks ago, I wrote about F&S Elektronik Systeme armStoneA8 ARM Cortex-A8 Single Board Computer that will be unveiled at Embedded World 2012 at the end of the month, and sell for 49 Euros for one week, before selling for its regular price (119 Euros). At the time there were notso many technical details, but this has changed with the release of a product brief and hardware documentation. The unnamed Cortex A8 processor is the Samsung S5PV210 running at 800 MHz or 1GHz depending on the model. Several models of the board are available, but they all share those common specifications: Samsung Cortex™A8 with 800MHZ (1GHz) 128MB (1GB) Flash, 256MB (512MB)-RAM TFT LCD-Controller up to XGA resolution 2D/3D and 5-Window Layer Multiformat CODEC (MPEG4, H.264, WMV9) H.264 1080p@30fps 1x (2x) Ethernet 10/100Mbit 1x USB2.0 Device, 1x USB2.0 Host 1x CAN2.0, 1x I2C, 1x SPI 3x Serial (RS232 with 3,3V-level) […]
