Kirkwood processors were developed for network connected consumer electronic equipment that are used in gateway/access point, set-top boxes, network storage, digital home media servers, point of services terminal, and plug computers (sheevaplug, dreamplug, guruplug, etc).
A plug computer is a small form factor server, intended to provide network-based services within the home. These ARM based devices provides always-on, always-connected, and environmentally-friendly computing that is readily available for developers.
The Guruplugs are one of the popular plug computers. More information on Guruplugs can be found here. Below is the technical specifications for a typical GuruPlug Server Plus
- 1.0 Ghz - 1.2 Ghz Processor (Marvell 88F6281)
- 512 MB 16-bit DDR2 RAM
- 512 MB NAND Flash
- 802.11 b/g WiFi
- SATA 2.0 port (eSATA)
- 2 x Gigabit Ethernet
- 2 x 16550 compatible UART interfaces (external JTAG adapter)
- 2 x USB 2.0 ports
- 1 x MicroSD Slot
Running Fedora on a Kirkwood Device
This page will give a user detailed instructions for running Fedora 17 GA on a Kirkwood based device. The F17 GA image provides a user with a minimal text based installation to a serial console. At the moment there is no GUI image available. F17 GA image has been tested to run on GuruPlug Server Plus using microSD card.
Download the image
The first step is to download the Fedora 17 image. The prebuilt images include kernels and can be written directly to an microSD Card and requires additional steps (uboot configurations) to boot. The serial console image requires a minimum of 2GB card.
Writing the Image
Please be aware that writing the image to any drive (SD/microSD/USB/Hard Drive) will erase any existing data in that drive.
The image can be written to a microSD card as long as it meets the minimum size requirements noted above (2GB for the serial image)
- Connect the microSD card to a computer and make a note of the drive.
- To write the image to a microSD card run the following command (Please change the drive to the location of the microSD card)
xzcat Fedora-17-arm-kirkwood-mmcblk0.img.xz > /dev/<location-of-your-SD-card>
- Once completed run the command below to ensure the entire image is written to the card
- 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 microSD card to write the files to. Click "Write". Be very careful during this step - all data on the selected drive will be lost!
- Please note that the Default Archive Utility.app will not extract the .xz file. You will have to use a third party app to decompress it. There are multiple options for that
- Once the xz utility is installed, open a terminal and make a note of your current drives.
- Connect the microSD card to the mac and make a note of the drive.
- Change directory to where the .xz file is located
- If you are using xz from the .pkg file or macport or homebrew then run the following command
xzcat Fedora-17-arm-kirkwood-mmcblk0.img.xz > /dev/<location-of-your-microSD-card>
- If you are using the App Store Unarchiver app then just click and decompress the .xz file and then run the following
dd if=Fedora-17-arm-kirkwood-mmcblk0.img of=/dev/<location-of-your-microSD-card>
- Click and eject the microSD card
