Technically I reversed their library only --- the ROM is almost
impossible to reverse; it's much harder since the library still had
the debugging symbols and wasn't stripped so the functions all had
their names still etc...

The only ROM calls I use are to interface to the flash and that's
becuase I'm lazy.

Yes, that one. Here is the patch:

http://git.devl.org/?p=malvira/libmc1322x.git;a=commitdiff;h=36361e1eb0eba99c8ab7807fa2f977c80a3be05c;hp=4035dc44f3db1b90cdb0cf51e6ce3d90204294d9

I have no clue why it segfaults on the original line (although I
understand, sometimes my brain segfaults on the original line). I came
up with that first line empirically to make the assembled instruction
right. If you squint hard enough you can convince yourself that it
makes some kind of sense.

Sure! I am planning to do a stm32w board. ST is supporting Contiki and
the radio library links directly with GCC --- so no reversing should
be necessary (unless there code doesn't work well). The stm32W should
be available Q4.

I'm planning to do rev2 of a USB stick version of the econotag and
will be getting FCC cert. for that. Also a bunch of new modules. I'm
planning to do the Xbee and Mbed footprint, a castellated small
module, a castellated bigger module that brings out all of the I/O
(all 64 pins), and a first rev of a mc13224v with PA.

Anyone have any thing on there hardware wishlist?
