Hi,

As a part of research activities the Embedded Systems - Open Platform Group
from Siemens Corporate Technology we are working on adding support for
the IEEE 802.15.4 Wireless Personal Area Networks to the Linux. Our current
implementation is neither certified nor even feature complete. However
we'd like to present current state of our patchset to the Linux developers
community to gain comments, fixes, ideas, etc. This is not yet a pull request,
but more like an RFC.

Does this stack work with the Atmel USB version of at86rf230?
ATAVRRZUSBSTICK, http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4396

No, we do not support Atmel USB sticks, nor we do not have plans for
adding support
for it in the foreseable feature. However if the onboard ATmega can be
programmed to
provide usb-serial interface, one can use/adapt our serial discipline
driver to control it.
One will still have to write firmware for the on-stick ATmega chip.

Or you can add support for any existing interface that is provided by
RazorUSB card by yourself.
We tried to make mac802154 drivers easy to implement.

It's not so simple to plug in the at86rf230 using SPI. Supporting USB
sticks lets you develop on a desktop PC.

Hmm. One can solder (e.g.) the FTDI 2232 together with AT86RF230/231
and use that combo
instead of RazorUSB sticks.

Everything is there on USB stick. Interface, Zigbee chip, antenna, power, etc..
And they are cheap $40.

freaklabs.org is using ATAVRRZUSBSTICK

I'll look for the interface they are using to control sticks and check
how easy will it be to
write a driver for it.

For development purposes you don't want to download the stack into the
USB stick, you just want to use USB as a transparent pass-through to
the Zigbee chip.

I have a Raven kit ordered, it will be here next week.
