Aaron,
Great idea to improve the OpenMote integration! Have you tried
contacting the OpenMote developers for guidance? In my experience they
have been very helpful and accommodating. I expect they would appreciate
your effort.

Hi,
I'd like to try and improve RIOT OS support for the OpenMote platform
in general, and the TI cc2538 MCU specifically. The most pressing item
for me currently is RF support, but I would also like to see support
for the ROM API and a few other things (including the sensors on the
OpenBattery board, eventually).
I'm new to RIOT and thought I'd try to clear up a few things before
getting my hands dirty, so you'll have to excuse me if some of these
questions seem obvious/stupid/irrelevant:
1) TI provide open-source firmware for the cc2538, but I can't find
any trace of it in the RIOT tree. It seems like there are a few
cherry-picked bits and pieces but not in the same format/layout as the
original firmware. Is there a reason for not including TI's firmware
in the tree verbatim (I'm thinking licensing/re-distribution issues,
architectural or coding-style differences, etc)? It seems like this
would make fully supporting the MCU a lot easier.
2) To avoid duplication of effort, is there anyone else already
working on RF support for this chip?
3) Where should a hypothetical RF driver for the cc2538 live in the
tree? Since it's on-chip should it live in the cpu subdir? Or
programmed as a "module" the same way as for peripherals?
4) Are there any guidelines or example code for this kind of work? The
only other on-chip RF driver I could find to use as a reference is for
the nrf51. Perhaps this will do to get me on the right track, but just
thought I'd check if there's something I missed.
Thanks!
/Aaron
