DDR Eval board

General Information

This board was primarily built to verify the operation of DDR memory on the ST40RA166. At the moment, it has been decided not to put this board into production, so there are a very limited number available. The 1.0 Linux release does not support this board, but subsequent releases do.

The board has one 3.3V PCI slot, on board PCMCIA,ethernet, and USB. It also has the advantage of a relatively small form factor. All peripherals are fully supported. The board has 64Megs of 64 bit DDR memory, and 8Megs of flash. In use, this board is very stable.
