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 – […]

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.

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 […]

Raspberry Pi OpenGL and OpenMAX IL “Hello World!” Applications

As you may already know, Raspberry Pi has released their first SD card image with Debian. This morning, I explained how to use that image in qemu. I’ve been waiting for samples to take advantage of the power Videocore GPU inside Broadcom BCM2835 SoC used in the Raspberry Pi board and the goods news is that they added Hello World code samples in C to make use of those capabilities. The sample are located in /opt/vc/src/hello_pi directory: hello_audio – Audio output demo using OpenMAX IL through the ilcient helper library hello_triangle – A rotating cube rendered with OpenGL ES with 3 images used as textures on the cube faces. hello_video – Video decode demo using OpenMAX IL through the ilcient helper library You can either compile those samples in the board or cross-compile them in your host machine. Since you need the GPU, you will obviously not be able to […]

Raspberry Pi Releases 1st SD Card Image (Debian) – How-to use it in QEMU

The Raspberry Pi Foundation has just released the first SD Card Image that you will be able to use with your Raspberry Pi board. This image is based on Debian Squeeze (6.0) and comes with  LXDE user interface and Midori browser, development tools, and sample code for accessing the multimedia functionality on the device. You can download it using BitTorrent: debian6-17-02-2012.zip.torrent (preferred method) or via one of the many http mirrors available on RPi Community page. This image contains all necessary files including the binary blob and closed source libraries, the kernel and the root file systems. If you want to to prepare an SD Card with this image simply use dd in Linux: unzip debian6-17-02-2012.zip sudo dd if=debian6-17-02-2012/debian6-17-02-2012.img of={sd_card_path} where sd_card_path is the device pointing to you SD Card (e.g. /dev/sdc). Make sure you use the correct device (e.g. with fdisk -l) or you may wipeout your hard drive […]

Cymbet EnerChip Solid State Batteries and Energy Harvesting Evaluation Kits

Cymbet has developed rechargeable solid state batteries called EnerChip for Embedded Energy, Power Backup and Energy Harvesting. Applications include backing up Real Time Clocks (RTC), Micro-controllers (MCU) and SRAM devices. The company says “EnerChips are ideal for energy harvesting powered devices such as wireless sensors, medical devices, data loggers and remote location tracking equipment.” Those chipsets aim at replacing batteries such as CR2032 batteries that you can find in watches, calculators and other low power devices. The company emphasized three key benefits of such “batteries”: EnerChips are more than 10x smaller than non-rechargeable coin cell batteries EnerChips last 3x longer than conventional coin cell batteries EnerChips are less expensive to use than conventional coin cell batteries or super caps. The price starts at 20 US cents in volume quantities. You can watch the promotion video below for an overview of those chips. Cymbet shows a lot of mobile phones in their video, […]
