How to build qemu-system-arm in Linux

Most (all?) Linux distributions have a binary package for qemu-system (including qemu-system-arm) in order to emulate non-x86 targets such as ARM, MIPS, PPC, Alpha and more. However, in some case you may need to very latest version of qemu-system and it may not be able yet for your distribution. Here’s how to do to build qemu-system-arm without building all qemu-system-***: Download the latest stable version of qemu (qemu 1.0.1 at the time this post was written):

wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

1	wget http://wiki.qemu.org/download/qemu-1.0.1.tar.gz

or get the latest source code (development tree) which has the very latest features and bug fixes, but may not work or compile:

git clone git://git.qemu.org/qemu.git

1	git clone git://git.qemu.org/qemu.git

or get the latest source code from linaro (which may be more up-to-date for ARM targets):

git clone git://git.linaro.org/qemu/qemu-linaro.git

1	git clone git://git.linaro.org/qemu/qemu-linaro.git

Configure qemu to build ARM targets:

cd qemu
./configure --target-list=arm-softmmu,arm-linux-user

1 2	cd qemu ./configure --target-list=arm-softmmu,arm-linux-user

Build and install qemu-system-arm:

make -j 2
sudo make install

1 2	make -j 2 sudo make install

Verify the latest version of qemu-ssytem-arm is installed:

# qemu-system-arm --version
QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

1 2	# qemu-system-arm --version QEMU emulator version 1.0,1, Copyright (c) 2003-2008 Fabrice Bellard

Instructions to Run Raspberry Pi Fedora 14 Remix in QEMU

As mentioned in my previous post, the Raspberry Pi Foundation has just released the Fedora 14 Remix SD card image that can be installed either via installer (easiest method) or using dd / windd as with the previous image. In this blog post, I’ll give the instructions how to run Raspberry Pi Fedora 14 Remix in QEMU using a similar method than the one I used for Debian Squeeze. I tested since in machines with Ubuntu 10.04 LTS and Debian 6.0.4. Download the image using BitTorrent raspberrypi-fedora-remix-14-r1.img.gz.torrent or via the HTTP link available on Raspberry Pi Download page. Decompress the image:

gzip -d raspberrypi-fedora-remix-14-r1.img.gz

1	gzip -d raspberrypi-fedora-remix-14-r1.img.gz

Download kernel 3.0.4 image for qemu, if you don’t have it yet.

wget http://dl.dropbox.com/u/45842273/zImage

1	wget http://dl.dropbox.com/u/45842273/zImage

Since the rootfs is full (in the real board it will be resized to the size of the SD Card), we need to increase the size of the rootfs partition. First create and empty 3G […]

Raspberry Pi Releases Arch Linux SD Card Image

The Raspberry Pi Foundation has just announced the release of Arch Linux for the Raspberry Pi. This image is based on a minimal image of Arch Linux and does not come with a graphical interface. This distribution may not be suitable for beginners and you may be better off using the Debian SD Card image or even the upcoming Fedora 14 Raspberry Pi Remix image. You can always install extra packages with Pacman, the Arch Linux package manager. To update the package list:

pacman -Syu

1	pacman -Syu

To Install LXDE Graphical Interface:

pacman -S lxde xorg-xinit xf86-video-fbdev

1	pacman -S lxde xorg-xinit xf86-video-fbdev

To run LXDE:

xinit /usr/bin/lxsession

1	xinit /usr/bin/lxsession

You can download it using BitTorrent: archlinuxarm-01-03-2012.zip.torrent (preferred method) or via one of the HTTP mirrors: archlinuxarm-01-03-2012.zip. (This link will redirect your download to the closest available HTTP server). The default login credentials are: root/root I haven’t tried it, but you should be able to use this release in qemu, by following instructions similar to the one […]

How to Install Windows 8 in Linux with QEMU

Microsoft has just released Windows 8 Consumer Preview. Here’s a method to install Windows 8 in Linux using KVM and Qemu. You can use this beta version of Windows 8 until the 15th of January 2013, after which it will be unusable. Here are the requirements to install Windows 8: 1 GHz Processor or greater 1 GB RAM 20 GB free storage for the 64-bit version Before you start, make sure your processor supports Intel Virtualization Technology (VT) or AMD’s AMD V CPU virtualization extensions. Type this command to check vmx or svm flags:

egrep --color "(vmx|svm)" /proc/cpuinfo

1	egrep --color "(vmx\|svm)" /proc/cpuinfo

If this is the case, you can install KVM. Type the following command for RPM-based distributions such as Fedora:

sudo yum install kvm

1	sudo yum install kvm

or the following command for Debian or Ubuntu:

sudo apt-get install qemu-kvm

1	sudo apt-get install qemu-kvm

Then download the ISO image of Windows 8 on Microsoft website (64-bit version) :

wget http://iso.esd.microsoft.com/WCPDL/BD1B8A49393E30CC9C4E5C88457D73E964F1F3B18/Windows8-ConsumerPreview-64bit-English.iso

Free Electrons Releases Embedded Linux Training Materials

Free Electrons, a technology company offering embedded Linux consulting services as well as embedded Linux training, has released their training materials for Linux and system development for embedded systems including their Lab sessions. The training materials are available in their git repository in LaTeX format. If you want the latest documentation in PDF, you’ll need to build it by following those steps: Install the required packages:

sudo apt-get install git dia inkscape texlive-full python-pygments

1	sudo apt-get install git dia inkscape texlive-full python-pygments

Get the embedded Linux slides source:

git clone <a href="git://git.free-electrons.com/training-materials.git">git://git.free-electrons.com/training-materials.git</a>

1	git clone <a href="git://git.free-electrons.com/training-materials.git">git://git.free-electrons.com/training-materials.git</a>

Build the training materials:

cd training-materials
make full-sysdev-labs.pdf
make full-kernel-labs.pdf
make full-sysdev-slides.pdf

cd training-materials

make full-sysdev-labs.pdf

make full-kernel-labs.pdf

make full-sysdev-slides.pdf

The last three commands will generate the PDF files respectively: full-sysdev-labs.pdf – Embedded Linux Training Lab Book (58 pages) with instructions for the IGEPv2 board based on on TI DM3730 or OMAP3530. full-kernel-labs.pdf – Linux kernel and driver development training Lab Book (37 pages) full-sysdev-slides.pdf – Embedded Linux system development presentation slides (506 pages) Free Electrons also have slightly older version of full-kernel-labs.pdf and full-sysdev-slides.pdf available for download as PDF so […]

B2G (Boot to Gecko) Video Demo at MWC 2012

B2G (Boot to Gecko) is an open source HTML5-based operating system targeting mobile devices by the Mozilla Foundation. This OS runs on top of Linux and uses Firefox as the web browser. You can get further details on my previous post “Mozilla Boot to Gecko (B2G) OS Is Coming to Your Smartphone“. As previously announced, Mozilla showcased B2G on a Samsung Galaxy S2 at Mobile World Congress 2012. Every apps are written in HTML5 including the camera application that uses HTML5 Media Capture and Canvas for real-time effects. Engadget was there and shot the video demo below. If you have a Samsung Galaxy S2, you can build and try it on your device. This is experimental, so there is always the risk of bricking your phone.
