Thanks guys for the reply.

I am working on a project using Omega2S that will be mass produced and i need to make sure the emmc compatibility.
The Omega2S did not mention the version of eMMC for the module but on the schematics of the devkit with emmc it uses the Toshiba THGBMBG6D1KBAIL. From quick search at google it indicates that this supports JEDEC 5.0. But the 5.0 version implements the DS or the data Strobe Pin which is not available on the Omega2S.

Is it right to think that the Omega2S only supports JEDEC 4.51 and below? Or maybe I can leave out the DS pin (Data Strobe) and the emmc works as 4.5x? But if that's the case why is it not reflected on their devkit schematics?

Im still learning this emmc and I welcome any ideas.
@Douglas-Kryder thanks for the link

There are few eMMC's I could find such as those from Toshiba(like the one in Omega2S devkit), Micron and Kingston, but most of them are out of stock some no longer produced, it's even harder to find under the 4GB density. I will be happy if somebody can make a suggestions or recommendations on which one to use best.

On another question related to eMMC, they are produced using different standard, to ensure operation and compatibility, does it matter to Omega2S the JEDEC standard eMMC is implemented say 4.1, 5.0 and 5.1. or its not at all related?
