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 Freescale iMX6 Quad Sabre Lite Development Board
i.MX6q SABRE Lite Board is a low-cost development platform based on Freescale Quad Core Cortex A9 i.MX 6Quad Application Processor. This will probably be the first low cost ARM quad-core development board to hit the market. Nvidia has previously announced the CARMA Tegra 3 CUDA Development Kit, but the price has not been announced and when I look at the picture of the board and the specs, “low cost” does not come to mind. Here are the technical specifications for the Sabre Lite board: Quad-Core ARM® Cortex A9 processor at 1GHz per core 1GB DDR3 @ 532MHz 3 display ports (RGB, LVDS, and HDMI 1.4a) Two camera ports (1xParallel, 1x MIPI CSI-2) Multi-stream-capable HD video engine delivering H.264 1080p60 decode,1080p30 encode and 3-D video playback in HD Triple Play Graphics system consisting of a Quad-shader 3D unit, and a separate 2-D and separate OpenVG Vertex acceleration engine for superior 3D, […]
Linaro 12.02 Release with Kernel 3.3-rc
Linaro has just released version 12.02 based on Linux Kernel 3.3-rc and Android 4.0.3. Among the key points, they have started to work on Freescale i.MX6 SabreLite board, included libav 0.8 to Ubuntu images which provides up to 160% performance improvement while playing real-media videos and XBMC is available via PPA. Here are the highlights of the release: Android Linaro Android can now be built with current GCC 4.7 snapshots. A 4.7 based toolchain build preview is also available. Linaro Android can boot on iMX6 Sabrelite boards. All test result spreadsheets have been streamlined and are now easier to use. Bluetooth enablement have been completed for the Origen board. A Prototype of using camera on Snowball was made. Presentations Given by Linaro Android Team this cycle “Binary Blobs Attack!!!” – Embedded Linux Conference. “What Android and Embedded Linux can learn from each other” – Embedded Linux Conference. “Integrating Projects Using […]

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) […]
Canonical Brings Ubuntu Desktop to Multi-Core Android Smartphones
Canonical is pushing to move Ubuntu beyond Desktop PC, and we’ve already seen some mockups for Ubuntu Smartphones and the recent Ubuntu TV announcement. The Ubuntu smartphone is not there yet, but Canonical has another idea: running Ubuntu Desktop on your multi-core Android smartphone connected to a TV/Monitor via its HDMI or MHL interface, making Canonical, another company joining “your smartphone is your laptop” trend. Ubuntu for Android will provide a full desktop experience and include office software (which apparently is Google Docs…) , web browsers (Chromium and Firefox), an email clients (Thunderbird) and media applications on Android phones docked to a screen and keyboard. Canonical claims the transition between Android and Ubuntu is seamless thanks to tight integration with the Android service layer. Ubuntu and Android share the same kernel. When docked, the Ubuntu OS boots and runs concurrently with Android. This allows both mobile and desktop functionality to […]
Seneca Uses GuruPlug Server Farm to Build Raspberry Pi Fedora Distribution
Prior to the Raspberry Pi Fedora 14 Remix launch party, Seneca has uploaded a video showing the work they have done to have Fedora 14 work on Raspberry Pi. Here are some interesting points ion this video: All basics application such as a web browser, office suite, the components you need to build a LAMP (Linux, Apache, MySQL, PHP) server… are already working. 2D graphics acceleration is not implemented yet, so the first release may feel a bit sluggish. But eventually, since the Raspberry Pi has a pretty good GPU, 2D support (OpenVG in Cairo library?) will be implemented at some points in time, either by Seneca or other people in the development community. Seneca uses around 60 ARM devices in their build farm that generates all the binaries for the Fedora ARM Remix release (e.g. the ones you can get with “yum install”) and among those device there are […]
