And the OMAP3 has no specific eMMC interface. It has 3 MMC interfaces. 2 of them are already used and the third one is not available. Maybe the schematics in the system manual give some more background information: http://projects.goldelico.com/p/gta04-main/page/Manual/ BR, Nikolaus > On May 13, 2015 10:05 AM, "Dr. H.
