Hi,

There is one thing I do not understand still. Where does it write or read from, I mean which address. With that code I can write or read two bytes okay but where does it go in the memory(which address) that I am trying to write. And the code is running on NIOS right? Also it the function is "area" default? One other thing is that I imagined NIOS-SPI-RAM kind a system but should the other part the part that is not NIOS be intelligent as well? Looks like there is more than one thing after all :)
