Windows 7 support for eMMC

NTDEV
1

Hi All
Does Windows 7 support eMMC V4.5 driver natively ? . If not , then what is the complexity involved in writing that driver .Whether it has to be developed from scratch or there are some samples available in WDK ?
Also if eMMC driver is implemented in Windows 7 , should we make changes in filesystem also ?

Thanks

Any suggestions ??

Please. You posted your question in the middle of the night in the US,
which is where a majority of the list regulars reside. You need to wait
more than 6 1/2 hours before demanding a response.

Did you even try it? eMMC is just a physical packaging standard. From
a software point of view, it’s just MMC, which Windows handles just fine.

Hi Tim
First of all sorry for my impatience .

Our requirement is to develop a storage driver for custom board that has eMMC and the driver should comply with the JEDEC emmc v4.5 spec . In the following post I found that packet commands are not supported in Windows 8 but in Windows 8.1 it is supported. So is there any restrictions in Windows 7 for eMMC V4.5 ?

Also read in some link that filesystem changes are required to utilize the complete functionality of eMMC V4.5 spec. is it true?

Someone else will have to adopt this thread. This just went beyond my
depth.

Can anybody help me out ?

I’ll bite. As Doron told the OP in the thread you referenced, this is supported in Windows 8.1 and not in Windows 7.

So… if you need support in Windows 7, you’ll have to implement it yourself.

Finally, and with all due respect, if you have to ask US what you need to do to implement this driver for Windows V7, then you might not be the right guy to be trying to do the design for that projects…

Hi Peter
Maybe I have put my question in a wrong manner… The requirement is to develop a eMMC driver in Windows 7 which should comply with JEDEC emmc v4.5 spec . And as per the threads, it is clear that there is no inbox driver available in Windows 7 like Windows 8 or 8.1 . So we need to develop our own driver for Windows 7 to support the same . Thank you all for your kind reply.
