At least, it works fine in crosstool-NG! ;-)

The (very light!) home seems to be hosted at uClinux.org:
  http://uclinux.org/bFLT/

The latest release tarball I could find is really really old:
  http://uclinux.org/pub/uClinux/utilities/elf2flt-20020214.tar.gz

Crosstool-NG is using the cvs repository:
  http://cvs.uclinux.org/cgi-bin/cvsweb.cgi/elf2flt/

And:
  cvs -z3 -d:pserver:anonymous at cvs.uclinux.org:/var/cvs co -P elf2flt

The repository is not really live, but was last touched 5 weeks ago (which
is not that old). It mostly gets fixes nowadays.

Regards,
Yann E. MORIN.
