the connections are fine.The memory just goes from 0x0 and 0x7ffff.After setting THOSE boundaries ,memory test goes ok,though sopc builder address range is between 0x0 and 0xfffff.Nothing i can do about that ,because that seems to be default.I use Cypress-like SRAM (ISSTIS61VPS51236A 512x36)- It has same pinout as of cypress.I have noticed this problem keeps popping up over and over again along the years(i ran into posts dating back to 2005)
