Honored Contributorhi again.
got a avalon master and slave running in "my custom vhdl" the on-chip memory has base address 0x8000-0xFFFF, but how do i figure out where niosII is storing variables in the memory ? cant find a .map file (probably called something else). Anyway if i write to 0x8000 from vhdl code and read from 0x8000 in nios i dont get the correct data, so im thinking something else i writing to that addresse as well. thanks stefan
