eMMC 5.0 support in i.MX6Q

[vishakh]

Hi,

We are developing a custom board based on i.MX6Q. Here we need to connect eMMC 5.0(with data strobe signal NC).

Based on the discussion in https://community.freescale.com/thread/325001#comment-409823, it is possible to connect eMMC 5.0 to i.MX6Q(with driver modification).

Can we follow the same procedure(by changing the check value of card->ext_csd.rev) in linux 3.0.35?

Will it be possible to boot from eMMC, without any concerns on flashing eMMC from MFG tool?

Thanks and Regards,

Vishakh

Hi Vishakh,

Yes, you just need to modify the value of card->ext_csd.rev as you see in that thread, The default emmc supported is eMMC 4.4 in linux 3.0.35. after you change it then the eMMC 5.0 can work as an eMMC 4.4.  And there is no concerns on flashing eMMC from MFG tool. :smileyhappy:
Have a great day,
Dan
