Have look at this TEP:

If the CPU is supported by GCC then is should be easier than otherwise.
The 8051 (which is present in CC2430 for example) is not. Martin Leopold
managed to port TinyOS to it by mangling the C code produced by nesC. You
can see the result here:
http://tinyos8051wg.sourceforge.net/
I recently made an attempt to do it without mangling for SDCC and I made
good progress with it but I haven't finish it yet. :-)
