Well if this is indeed what I want (not entirely sure because I don't have much experience with using SDRAM) then I did not set it this way explicitly. ALso, the warning came into my system after I added the SDRAM. When I first added the component, this warning was not there. It only came several compilations and changes later.
Thank you for your input. I can't see any direct consequences of any of these warnings.... I am basically looking for the reason why my code always fails when run from SDRAM.... The infamous verify failed message is killing me...
