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.

Linaro Android Tutorial with the Pandaboard

Zach Pfeffer, the tech lead of the Linaro Android working group, gave a tutorial about Linaro Android at Linaro Connect Q4.11. During this tutorial, attendees were shown how to download a recent build for the pandaboard, how to make a bootable SD card image using the linaro-android-media-create command and how to boot the board with it. The full setup was composed of a Pandaboard connected to a HDMI monitor with a keyboard and mouse connected to the board as well as serial to USB cable to connect to the development machine. He also used an SD card reader to generate the bootable Android image. The images are available at Android Linaro Build Service. There are quite a few build named after the supported board (e..g panda for pandaboard, snowball for ST Ericsson Snowball etc..) and the kernel version (tracking = latest linaro kernel, staging = stable linaro kernel). Then an […]

Linaro 11.10 Release with Linux Kernel 3.1

Linaro has just released version 11.10 based on Linux Kernel 3.1. Here are the highlights of the release: Android Audio playback and recording works on LEB-panda. TJBench into all Android builds benchmarked against the original Android libjpeg implementation: TomGall/LibJpegTurbo All strict-aliasing violations in 2.3.5 have been fixed and sent to AOSP. (for build optimization) Linaro Gerrit is integrated with Android Build Service for change verification as part of Continuous Integration effort. Tip toolchain tracked and released against all targets for 11.10. iMX53 will now boot with a 3.0 or later Android Kernel. The multimedia test application has been extended to cover encoding and give better benchmark results. Linaro’s Android distribution can now base builds off a tip toolchain build. Linaro’s 11.09 toolchain has been benchmarked. USB camera (UVC) now works on linaro-android builds. Developer Platform The Linux Linaro packages are now generated and validated in a continuous integration loop. New […]

Pandaboard Cloud Cluster Running Google App Engine

Noritsuna Imamura showed an ARM cloud cluster built with 6 Pandaboards at Linaro Connect Q4.11. Noritsuna is a member of the Open Embedded Software Foundation (OESF), a Japanese organization that support Open Source embedded software. The cluster is made of 6 panda boards with a total 6 GB of RAM (1GB per board) that runs the Google App Engine (http://code.google.com/appengine/) in Ubuntu/Linaro 11.09 release. The middleware used is TyphoonAE, a full-featured and productive serving environment to run Google App Engine (Python) applications. This type of server hosts web applications such as Rietveld (used in the demo below) to be run on (thin) clients. There are also plenty of other software (required by Google App Engine) that runs in this ARM cloud such as MySQL, Apache2, memcached and more. In the video, a power meter shows that the cluster consumes about 35 W in low activity mode. Norisuna had a comparison […]

Run 2 OS Simultaneously on ARM (OMAP4) with Codezero Embedded Hypervisor

B Labs, a company specializing in ARM Virtualization, was at ARM Techcon 2011 showcasing Codezero, their Embedded Hypervisor to run multiple Linux OS such as Android and Chrome OS on ARM processors. The main purpose of running 2 operating systems is to separate home and enterprise operating systems in mobile devices so that enterprise data is safe. Charbax (ARMDevices.net) interviewed Bahadir Baldan, founder of B Labs, and showed a demo running 2 Android instances and another running Android and Linux in pandaboard. The overhead is 10 to 15% according to B Labs, so the performance hit is minimal. They have already managed to run 4 OS on quad core processors with good performance. They are not able to run Windows operating systems (e.g. Windows Mobile 7.5/ Windows 8) yet, because Cortex A9 processors lack virtualization extensions. This will however be feasible with Cortex A15 processors as binary virtualization will be available. […]

Mentor Embedded Inflexion UI Demo for STB/IPTV

Mentor Embedded developed a user interface for STB/IPTV demo using their Inflexion UI framework and they showcase it at ARM Techcon 2011. The demo runs on Android and looks very smooth thanks to OpenGL ES hardware acceleration. They also have a separate demo with pandaboard and a laptop running Sourcery codebench development tool to show how to develop a simple user interface with Inflexion UI. Finally, they showcase “Stella“, a self-balancing robot with 2 wheels. The board is based on TI Stellartis (Cortex M3) micro-controller and runs Mentor Embedded Nucleus RTOS.

Ubuntu on Tegra 2 Netbook and Ubuntu Server on Pandaboard

Canonical showcases several demos at ARM Techcon 2011: Toshiba AC-100 Netbook (Nvidia Tegra 2) running Ubuntu 11.10. with Unity interface. Freescale i.MX53 board playing a 1080p video in Ubuntu 11.10. TI Pandaboard running Ubuntu 11.10 Server Edition. Ubuntu 11.04 is not officially supported for Toshiba AC-100, but the community if working on it and the image can be downloaded at http://ac100.gudinna.com/ Canonical however supports Netbook and Headless (Server) edition for OMAP3 (Beagleboard) and OMAP4 (Pandaboard). Those image are available at https://wiki.ubuntu.com/ARM/NattyReleaseNotes Watch the interview by Charbax and demos in the video below.
