How to Transfer files between the Host and Qemu via SSH and NFS

Last week, I wrote a blog post explaining how to copy files to a qemu image by mounting the qemu image in the host. This is only useful if emulated platform does not support networking. If networking is enabled, using SSH (Secure Shell) or NFS (Network File System) is more convenient. Using SSH with Qemu To initiate the SSH connection from qemu, there is actually nothing extra to do as long as you have sshd installed and running on the host. If it is not installed simply run sudo apt-get install openssh-shell on the host. This will install and automatically sshd. To initiate the SSH connection from the host, you’ll have to redirect the ssh port to an unknown port and start qemu as follow (for overo):

sudo qemu-system-arm -M overo -m 256 -drive file=./overo_sd_alip.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse -redir tcp:2222::22

1	sudo qemu-system-arm -M overo -m 256 -drive file=./overo_sd_alip.img,if=sd,cache=writeback -clock unix -serial stdio -device usb-kbd -device usb-mouse -redir tcp:2222::22

Please refer to Beagleboard Emulator in Ubuntu with Qemu for the detailed instructions on how to setup qemu to emulate beagleboard or […]

How to Transfer files between Host and Qemu

I previously posted instructions to install and run nano and ARM Linux Internet Platform (ALIP) distribution images for Overo and Beagleboard on QEMU, If the image support networking, you could use ssh (install dropbear server in qemu) or nfs to transfer files between the host computer and qemu, or even run your program from the NFS share. This should be possible to do that on the Overo emulator since it support Ethernet. However, although I can access Internet, I cannot access the host via ssh as the host is in a private subnetwork (192.168.0.0) and qemu in another (10.0.2.0). We would probably have to enable bridge networking for that but the tun driver is apparently not compiled in ALIP kernel. I’ll look into that later on. [Update: Finally, we don’t need tun/tap to make this work, please read http://www.cnx-software.com/2011/10/02/how-to-transfer-files-between-host-and-qemu-via-ssh-and-nfs/ for details.] Today, I’ll just show how to mount a Qemu […]

CraneBoard: Low Cost Development Board based on TI AM3517

The CraneBoard is a low-cost, open-source hardware development platform based on the AM3517 Sitara ARM Cortex-A8 microprocessor. The CraneBoard was announced in December 2010, can be purchased for 199 USD and can be an alternative to the Beagleboard-xM. AM3517 is especially suited to industrial applications and would be a preferable platform if your project needs CAN or PoE support. The board has less RAM (256 MB vs. 512MB) and no camera port. Here are the features and specifications of the board (I highlighted the differences with Beagleboard-xM in green): AM3517 Sitara ARM Cortex-A8 – 600MHz Integrated 3D Graphics Accelerator RAM: 256 MB NAND Flash: 256MB Support for on-chip peripherals: 10/100 EMAC USB OTG utilizing on-processor PHY 3.3V I/O CAN Bus DDR2 Power over Ethernet and other power options including USB and DC MMC/SD Card Support Fully open-source four-layer PCB Fully Open Source Linux Board Support package (2.6.32) Based on existing […]

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 […]
