How to access SRAM on CycloneIII dev kit - not via nios !

Hi,

never used the SSRAM on that kit but it should be possible.

First, on that board, the SSRAM data pins are shared with the Flash data pins.

Make sure Flash is in high-Z.

Second, since some of the control signals are hardwired, that probably means you can only use a subset of the SSRAM chips operating modes.

So, you need to take a look at the state of each hardwired signal and see what modes you can still use.

You may find that either

a) you can't use burst mode

b) you must use (some) burst mode

Lastly, your requirement (60 MHz 8bit write, 50 MHz 32bit write) is tricky.

Start by getting the SSRAM to work in a simpler 50 MHz 32 bit write, 32 bit read mode.
