Mon Aug 3 07:24:49 CEST 2009
STx AMC8548 board is an old, AMC form factor, MPC8548 based board intended
for RapidIO applications. It features 16MiB NAND flash, one DDR2 soDIMM
slot, ethernet on front panel and backplane, RapidIO on backplane, USB
controller on local bus (not currently enabled) and no PCI of any kind.
