I believe if you want the layout design (other than the gerbers) then you have to contact Spectrum Digital. Don't know how many layers the ref design is. Our implementation is 10 layers. > - the TI webpage says "On-board Ethernet controller with application > notes and schematics".

The MAC/PHY is external - it is attached to the AEMIF bus. To implement another ethernet interface you need to modify the CPLD code to add an additional chip select and modify drivers for the address space change. > - do I need to buy any software just to write applications for the > DM355 DVEVM or is everything that is needed part of the free software > packages?

You need to purchase the DVBSP when you intend to sell your product.
