Beagleboard Emulator in Ubuntu with Qemu

If you just want to try a program on Beagleboard, but do not want (or have the means) to purchase a board, you may be able to use qemu to emulate the Beagleboard or BeableBoard-xM. I’ll details the instructions to run the Nano build (minimal kernel) and the ARM Linux Internet Platform (ALIP) distribution for Beagleboard on qemu. Please read the full post before starting the installation before there are currently some issues such as no Ethernet support. First, install or update linaro-media-create: sudo add-apt-repository ppa:linaro-maintainers/tools sudo apt-get update sudo apt-get install linaro-image-tools Then download the nano image and omap3 hardware pack: wget http://releases.linaro.org/platform/linaro-n/nano/11.08/nano-n-tar-20110823-1.tar.gz wget http://releases.linaro.org/platform/linaro-n/nano/11.08/hwpack_linaro-omap3_20110823-0_armel_supported.tar.gz Generate the image for qemu: sudo linaro-media-create –image_file beagle_sd.img –dev beagle –binary nano-n-tar-20110823-1.tar.gz –hwpack hwpack_linaro-omap3_20110823-0_armel_supported.tar.gz If you don’t have it already, get the latest qemu-linaro package from Linaro Maintainers PPA: sudo apt-get install qemu-system Check the version is correct: qemu-system-arm -version QEMU emulator version […]

Embedded Systems Conference Boston 2011 Sessions Schedule

ESC Boston 2011 will take place on the 26-29 September 2011, four days of hands-on training, educational sessions and an interactive exhibit hall. There are 5 programs during the event: ESC Boston – Embedded software development tutorials for Android, Linux, microprocessors, QA, C programming, etc… DesignCon East – Hardware tutorials, e.g. SDRAM debugging, hardware encryption… DesignMED – Embedded systems development for embedded medical devices. Designing with LEDs! – LED hardware and drivers. DesignDays – Embedded systems sessions mainly presented by semiconductor companies and hands-on tutorials on specific platforms such as Beagleboard or TI MSP430 Chronos Wireless Watch. There are simply too many sessions (over 170) to list them all here. So I’ll selected a few among ESC Boston and DesignDays that look particularly interesting: Android Jump Start (Monday 26 – 8:00 – 17:00) by William Gatliff (Consultant, Freelance) and Karim Yaghmour (CEO, Opersys Inc.) . The features that make Android a great cell […]

Linaro 11.08 Release with Linux Kernel 3.0.3

Linaro has just released version 11.08 based on Linux Kernel 3.0.3 with support or TI Beagleboard, BeagleBoard-xM & Pandaboard,  ST Ericsson Snowball, Freescale i.MX53 development board and Samsung Origen board. Here are the highlights of the release: Android The Linaro 11.08 toolchain release of GCC 4.6 has compiled the Origen, BeagleBoard, BeagleBoard-xM, PandaBoard and Snowball builds, and are running Android 2.3.5 with a 3.0 Linux kernel. Together with the mainline kernel focused builds for BeagleBoard and PandaBoard and a preliminary i.MX53 build, the Android Platform Team ships 6 builds this month. A first! Android Platform code aliasing violations have been fixed allowing the use of strict-aliasing for better optimizations with gcc 4.6 based toolchains. The Android toolchain 11.08 has been released and has received numerous updates, including updated binutils and current gmp/mpfr/mpc. Benchmarks are available here. libjpeg-turbo 1.1.1 and ffmpeg with support for H.264 and WebM build are available on […]

Boot Linux in 300 milliseconds

MakeLinux.com managed to boot Linux from the bootloader to console within 300ms using a customized (and minimal) version of Linux running on Beagleboard based on TI OMAP 3530 (Cortex A8) as per their Super Fast Boot project. Here’s the analysis of the boot sequence and timings: Logging starts at 70 ms from reset. Boot time from reset is 300 + 70 = 370 ms. Logging starts at 330 ms from power on. Cold boot time is 330 + 300 = 630 ms. Loading of 1.5 MiB Linux image from NAND takes 237 ms with throughput 6 MiB/s. Code execution takes 60 ms or 43M CPU cycles. (For other CPU frequency execution time is different, but the number of processor cycles is the same) The most time-consuming operation is coping firmware from NAND flash. They used a Linux 2.6.32 kernel from DVSDK 3.01, in a minimal configuration (900KB footprint), the boot […]

Video Wall with Beagleboards and ffmpeg

There was a 6-Screen Video Wall at Embedded World 2011, powered by 6 Beagleboard xM (based on Texas Instruments OMAP 3 running @ 1Ghz – Cost: 149 USD / piece), connected vi Ethernet. In the video they explain that the system is running Linux Ångström and the video is played and synchronized over Ethernet with ffmpeg. After doing some research on how to do this, they are probably using omapfbplay with netsync enabled which you can compile as follows: NETSYNC=y OMAPFB=y make However, if you are using Linux Ångström, omapfbplay with netsync is enabled by default. This can also be done with the first version of Beagleboard (without Ethernet) via USB. They can also control each display independently and synchronize the mouse and keyboard thanks to Synergy.
