Hi Ralph,

See [0].

Radio board:

  - I would advice a 2.4 Ghz at86rf231 or at86rf233 [1].
     Supports async xmit handling and has the most supported hardware
     flags. Driver is at86rf230.

Interface:
  - What you mean with interface? Bus Interface? -> SPI. Or netlink
    interface? -> nl802154 with wpan-tools. Don't understand the
    question.

Linux platform:
  - I think you mean some architecture -> ARM. Then the platform, some
    board: The transceiver at [1] was made for RPi which works well on
    my side. But the RPi has a lack of mainline support. You have no
    USB, this means you have also no ethernet. If you don't need
    ethernet, then I would use a simple RPi. If you need ethernet I
    would advice to make some adapter board to add the [1] on a
    beaglebone [2], which have a good mainline support. This require
    some hardware hacking skills.

    Note: for RPi I also support you have no other support e.g. HDMI
    output or something else. SPI with RPi works mainline perfectly.

Over google I detected that spinics archive this mailinglist [3] (but
doesn't include the early days).
