ieee1394, Denx 3.1 (2.4.25+), PPC

[Jeff Angielski]

Has anybody out there gotten this combination of hardware and software
to work?  

I am trying to figure out if this is a problem with my particular
system/configuration or inherent in the current software baseline.  The
problem is that while all software loads and runs without error, I am
unable to detect any devices/nodes on the IEEE1394 bus.  


Thanks,
