Maybe I haven't looked well enough, though.
it's part of the default release ... the main package includes both bfin-uclinux and bfin-linux-uclibc > Anyway, since Blackfin supports bFLT, and almost all docs guide you how to > compile ones apps into bFLT, I don't see a reason to force people to use > FDPIC ELFs (which are also bigger in size, and don't support compression > IIRC).
