A screen shot of Fedora 18 for ARM on QEMU .

Contents

Versatile Express

The Versatile Express family of development platforms provides users with a modular board design for use testing different ARM SOC design implementations. QEMU provides the ability to emulate ARM Versatile Express for Cortex-A9 on your desktop computer for easy experimentation!

Technical Specifications

  • ARM Versatile Express for Cortex-A9
  • 1GB RAM
  • 10/100Mbit/s Ethernet

For more information on Versatile Express or QEMU visit their websites.

Running Fedora through QEMU

This page will give you detailed instructions for running Fedora 18 through QEMU. The tarball includes all that is needed to boot your system including the root filesystem image and the pre-extracted kernel and initramfs. Also, included for your convenience are two scripts to boot using a serial connection or the XFCE desktop.

Download the image

There are two Versatile Express images available for use with QEMU, a hard floating point (armhfp), and a software floating point(arm). If you are unsure of which to choose, the hard floating point image is recommended.:

Download and verify the checksum (armhfp used as an example):

wget http://dl.fedoraproject.org/pub/fedora-secondary/releases/18/Images/armhfp/Fedora-18-armhfp-Images-CHECKSUM
sha256sum --check Fedora-18-armhfp-Images-CHECKSUM

Preparing the Image

Linux Users

Extract the tarball using the graphical user interface or the following commandline option:

tar xvJf Fedora-18-vexpress-xfce-armhfp.tar.xz

Windows Users

QEMU is also available on Windows but is not yet covered in this guide. For more information on running QEMU on Windows please visit their website.

Using Fedora through QEMU

First you will need to install the ARM QEMU package (this example is using Fedora)

yum install qemu-system-arm

Once installed, change to the boot directory of the extracted kernel package:

cd Fedora-18-vexpress-xfce-armhfp/boot/

From there execute the provided script, choosing to boot with or without a graphical interface.

./boot-vexpress -h
Usage: ./boot-vexpress [--gui] --kernel=vmlinuz... --ramfs=initramfs --image=fsimage [--dtb=vexpress.dtb]

For serial console:

./boot-vexpress --kernel=vmlinuz-3.6.10-8.fc18.armv7hl --ramfs=initramfs-3.6.10-8.fc18.armv7hl.img --image=../Fedora-18-vexpress-xfce-armhfp.img

For XFCE Desktop:

./boot-vexpress --kernel=vmlinuz-3.6.10-8.fc18.armv7hl --ramfs=initramfs-3.6.10-8.fc18.armv7hl.img --image=../Fedora-18-vexpress-xfce-armhfp.img --gui

The default root password is "fedora". This should be changed immediately.

Release Notes

  • Images were composed using tools in Fedora 17 due to continuing work on Fedora 18.
  • When upgrading to the 3.7.X kernel you will require a device tree binary (.dtb) file for the system to boot. The provided 'boot-vexpress' script allows for the optional use of a 'dtb' file and will give a warning when booting kernels above 3.6.x.
    • The XFCE Desktop is not currently available when using the 3.7.x kernel.
