I don't know any free telephony project which will build and run on an
IP01, except the ones which have specifically been adapted for the
Blackfin. If you look at www.rowetel.com or www.astfin.org you will find
versions of Asterisk which have been adapted for the IP01.
Nobody has yet adapted Freeswitch for the Blackfin, and they probably
won't. The Blackfin lacks an MMU and cannot run Linux - it runs uCLinux,
which is a cut down Linux for machines of this type. It is quite
troublesome to get memory management to behave sanely on a machine
without an MMU. The Asterisk adaptions for the Blackfin have problems
with this too, but if you don't let the memory become too fragmented
they work OK.
The lack of floating point hardware in the Blackfin, and a number of
other embedded processors, can also cause performance issues. The core
functions of Freeswitch work reasonably well with emulated floating
point, but some things, like the FAX engine, are really too slow to be
very practical until more of the code is adapted to provide a fixed
