thanks for your quick reply. thet example pass memory test as well but i still do not have working project. I tried to extract utram component and put it to my project but my nios can not run using that memory. Do you have idea what is wrong .

You have mapped the tristate addressbus which reaches from 22..0 to 22..1 (the first lsb isn't used). That's right.

But then you assigned the sram from 22..1 to this bus. That't incorrect. You have to assign the sram from 21..0 to this bus.

the reason: the sram addressbus starts with FSA1. so you might think you have to left out FSA0 - but if you use flash you need the FSA0 and so the editor of the utram-interface considers that.
