A "Pandastack" used at Seneca College to build Fedora for ARM. There are eleven stacked Pandaboards in this configuration

Contents

Pandaboard

The Pandaboard is one of the most popular ARM devices available and provides users with either a desktop environment or minimal installation (text based).

Technical Specifications

  • 1 GHz Dual core Cortex A9 Processor (OMAP 4430-4460)
  • 1 GB DDR2 RAM
  • HDMI v1.3
  • 10/100Mbit/s Ethernet
  • 802.11 b/g/n WiFi

Running Fedora on a Pandaboard

This page will give you detailed instructions for running Fedora 18 Alpha on your Pandaboard. The provided image will provide both serial and the XFCE desktop.

Download the image

The first step is to download the Fedora 18 Alpha image. The prebuilt image includes everything you will need to boot your system and will require a minimum of 4GB for the root filesystem

Writing the Image

Linux Users

You can write the image to an SD card of your choosing but it does have to meet the minimum size requirements noted above (2GB for the serial image, 4GB for the XFCE Desktop). Connect the SD card to your computer and make note of the drive. To write the image to your SD card run the following command, changing the drive to the location of your SD card.

For the Serial Image:

xzcat Fedora-17-armhfp-panda-mmcblk0.img.xz > /dev/<location-of-your-SD-card>

For the XFCE Desktop:

xzcat Fedora-17-armhfp-panda-xfce-mmcblk0.img.xz > /dev/<location-of-your-SD-card>

Once completed run the below command to ensure the entire image is written to the card:

sync

Windows Users

  • You will need to download Win32 Image Writer as well as a tool to extract the image such as 7-Zip.
  • Once downloaded and installed right click on the disk image and select "7-Zip->Extract files here"
  • Launch Win 32 Disk Imager and select the extracted disk image and the SD card you would like to write the files to. Click "Write". Be very careful during this step - all data on the selected drive will be lost!

Mac Users

  • Please note that the Default Archive Utility.app will not extract the .xz file. A third party app will have to be used to decompress it. There are multiple options for that
    1. There is a Free App available in the App Store called Unarchiver.
    2. If mac homebrew or macport is already installed, then the xz utility can be downloaded and installed using one of those.
    3. The xz utils .pkg for mac can be downloaded and installed directly from xz utils
  • Once the xz utility is installed, open a terminal and make a note of the current drives.
ls /dev/disk?
  • Connect the SD card to the mac and make a note of the drive.
  • Open Disk Utility and make sure that the card and all the partitions in the card (if any) is unmounted
  • In the terminal change to the directory where the .xz file is located
  • If xz was installed from the .pkg or macport or homebrew then run the following command
xzcat Fedora-17-armhfp-panda-xfce-mmcblk0.img.xz > /dev/<location-of-the-SD-card>
  • If the Unarchiver app from App Store was used then just click and decompress the .xz file and then run the following (may require sudo)
dd if=Fedora-17-armhfp-panda-xfce-mmcblk0.img of=/dev/<location-of-the-SD-card>
  • Click and eject the SD card

Using Fedora on the Pandaboard

Connect the newly created media to your Pandaboard and power on. No further steps are required and your system should boot to a text based log in prompt (serial image) or to a graphical log in (XFCE Desktop image). The default root password is "fedoraarm". This should be changed immediately.

Known Issues

  • Yum requires the system time be correct for HTTPS to function. If yum updates are not working check your clock.
  • 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.
  • Images are designed to be written to 2GB (console) or 4GB (xfce) SD cards. On first boot the partition will be resized to the maximum allowable amount. On the second boot the filesystem will be resized to fill the expanded partition. This works for SD cards, SATA Disks, and SSD drives.
  • The XFCE Desktop image uses the HDMI port for display, which will work as a dvi-d also.
  • The powerVR gpu is currently not available in the omapdrm driver used in Fedora kernel-omap.
  • Each time the panda boots a new random MAC address is generated. This is because there is no EEPROM to store the mac address. To have the same eth0 MAC address after reboot the /etc/sysconfig/network-scripts/ifcfg-eth0 file needs to have MACADDR= line added.
  • Known release issues

Additional Support

There are Fedora ARM users all around the globe - if you need assistance, would like to provide feedback or contribute to Fedora ARM please visit us on the IRC - we can be found in #fedora-arm on Freenode. You can also contact us on the mailing list - arm@lists.fedoraproject.org


Extra Info

The image file can be loop mounted.

  • Inflate the archive:
unxz Fedora-17-armhfp-panda-xfce-mmcblk0.img.xz
  • Print the partition table:
fdisk -l Fedora-17-armhfp-panda-xfce-mmcblk0.img

Disk Fedora-17-armhfp-panda-xfce-mmcblk0.img: 3775 MB, 3775922176 bytes

  • The /boot partition starts at sector 63, where each sectore is 512 bytes.
mount -o loop,offset=$(( 63 * 512 )) Fedora-17-armhfp-panda-xfce-mmcblk0.img /mnt/boot
  • The rootfs partition starts are sector 1,044,225
mount -o loop,offset=$(( 1044255 * 512 )) Fedora-17-armhfp-panda-xfce-mmcblk0.img /mnt/rootfs

At this point you may customize the image however you wish.
