Beagle Board and Leopard Board

Hello all I currently have the BB XM and a Leopard Board DM368 and
trying to get them to talk over Ethernet, USB, and build image sensor
drivers for the DM368. Both use similar architectures (ARM Cortex-A8
and ARM9+Vid) but the link on TI page for the TMS320DM368 validation
kernel has a 404 error. Anyone out there in embedded world have a
line on where I can get a decent validation kernel source or have
actually made these 2 products talk over Ethernet and USB?

Thank you for your time
