Note that we have started to maintain a board with the same CPU, the
merkurboard http://osdwiki.open-entry.com/doku.php/en:projekte:merkur

We're maintaining a fork of contiki for this board but since contiki-ng
started nobody seems to maintain the 'classic' version anymore, the -ng
version seems to be solely targeting 16 or more bit CPUs.
See our fork https://github.com/osdomotics/osd-contiki

So we're currently looking into RIOT for this board.
If you drop support for the jiminy-mega256rfr2, please don't drop
support for the mega256rfr2 processor.

We've tested the RIOT support that exists for the mega256rfr2 and it
looks ok, flashing (with Arduino-compatible bootloader) using AVRdude
etc. works fine.

The radio-support for the mega256rfr2 is lacking, though, we were not
able to get 802.15.4 / 6loWPAN working so far. We're prepared to put
some work into the radio layer. Questions we're currently facing will
follow in separate mailinglist threads.
