This is the last time I answered this.  Maybe he has made progress.

That post gave info on the porting documentation and process.

That's probably a good starting point but you will need to make sure
__rtems__ is a predefine and not unix or linux.  Check out the minor 
differences most gcc/config/CPU/rtems* files make to a basic *-elf
configuration.

Use their source base and if there is a blackfin-elf target
supported, use that as a basis for blackfin-rtems.

Feel free to ask questions about the porting process and
if you need consulting help, that's what I am here for. :)
