Architectures/ARM/Fedora 18 Alpha/Vexpress

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

Running Fedora through QEMU

This page will give you detailed instructions for running Fedora 18 Alpha 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

The first step is to download the Fedora 18 Alpha image:

• Vexpress Tarball

Preparing the Image

Linux Users

Before extracting the vexpress image you will need to rename it as follows:

mv Fedora-18-Alpha-armhfp-vexpress-xfce.img.xz Fedora-18-Alpha-armhfp-vexpress-xfce.tar.xz

Now your ready to extract the tarball using the graphical user interface or the following commandline option:

tar xvJf Fedora-18-Alpha-armhfp-vexpress-xfce.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 armhfp-vexpress-mmcblk0/boot

From there execute the provided script. Depending on which option you selected for your download:

For serial console:

bash boot-vexpress vmlinuz-3.4.2-3.fc17.armv7hl initramfs-3.4.2-3.fc17.armv7hl.img /<path>/<to-image>/Fedora-17-armhfp-vexpress-mmcblk0.img

For XFCE Desktop:

bash boot-vexpress+x vmlinuz-3.4.2-3.fc17.armv7hl initramfs-3.4.2-3.fc17.armv7hl.img /<path>/<to-image>/Fedora-17-armhfp-vexpress-xfce-mmcblk0.img

Known Issues

• Yum requires the system time be correct for HTTPS to function. If yum updates are not working check your clock.
• Versatile Express images require the kernel parameter 'physmap.enabled=0' be passed to boot correctly. This is included in the boot-vexpress and boot-vexpress+x scripts.
• The tar.xz rootfs archives do not preserve SELinux information or file capabilities. If you use these to create your own filesystem image it is recommended that you switch SELinux to use warnings instead of enforcing for first boot, then relabel and reinstall packages that rely upon filesystem capabilities such as glibc-common and ping.
• Known release issues
