Cyclone III Development Board - Video Image Processing Suite - Hardware revisions?

solution for the DDR2-RAM (no solution for the utram yet):

The are two possible solutions for this issue.

The first solution means compatibility with the old Hardware, the second solution will use the new full memory of DDR2-RAM (bottom and top)

preparatory work for both solutions:

Go to pin planner and add the node: "memtop_ba[2]" to PIN_C23, IO-Standard SSTL-18 Class I, 12mA

Go to pin planner and add the node: "membot_ba[2]" to PIN_AH4, IO-Standard SSTL-18 Class I, 12mA

First solution (compatibility with old boards)

-simply tie the new both Pins to ground

Second solution (use the new more memory)

-go to QSYS / SOPC-Builder => DDR2 SDRAM Controller with Altmemphy => Memory Settings => modify parameters => bank address width => Change from 2 to 3

repeat it for both (top and bottom) DDR2

Best Regards
