Read/Write from SDRAM without Avalon

John

Yes, you should be able to do it without the Avalon bus, but then you have to generate all the bus signals to the SDRAM core.

A more hands-on approach would be to use Jeung Joon Lee's SDRAM IP at http://www.cmosexod.com (http://www.cmosexod.com) or maybe even the DDR design from http://www.opencores.org/projects.cgi/web/ddr_sdr/overview (http://www.opencores.org/projects.cgi/web/ddr_sdr/overview)

SDRAM is one of those dodgy devices. Rather stick to a design someone else spent a few weeks with before you try your own.
