The first development platform obtained by the FreedomBox project is the DreamPlug. DreamPlug development kits are available from the manufacturer, Globalscale Technologies, and resellers such as newIT in the UK and Spinifex in Australia.
See DreamPlugTesting for details on Debian support for this hardware.
Note that the factory firmware configs may vary between revisions of the hardware, and render some images incompatible.
A forum for these machines is at http://www.plugcomputer.org/plugforum/.
Load FreedomBox Debian images on your DreamPlug
If you have a DreamPlug, the easiest way of loading Debian on it is using pre-built downloadable images.
You may also regenerate them on your own using Bdale Garbee's freedom-maker tool : see FreedomBox/BuildImage
