Maintained in kernel and OE by Jonathan Cameron

This one is a small pxa271 board targeting wireless sensor apps (hence no real local interface)

  • 32MB RAM
  • 32MB Flash
  • CC2420 802.15.4 radio (currently not supported in mainline kernel but very very dodgy drivers are in older versions on Will be rewritten eventually to conform to new 802.15.4 framework in kernel.
