I keep starting anew with blackfin support due to the current problems:

* ADI uses their own 'distro', the rest of the world a custom buildroot
* You need to get gcc from blackfin SVN to get something to compile
* you need to choose either uclibc from blackfin svn or upstream uclibc

When you get to the point of building uclibc, the fun starts, since 
uclinux (not uclibc) has no proper shared library support, so you have 
to choose an emulation method (fdpic being one of the options).
 From that point on it's downhill, since various parts of uclibc have 
fork() in their code, gcc will ICE on other parts, etc.

My latest attempt was:

I still have the board, so if you make some progress I can test it :)
