Hi,

 

I am using iMX6UL in my design with JEDEC/MMC version 4.51 compliant eMMC MTFC4GACAAAM-1M WT. The eMMC part i am planning to use is not recommended for new design.

So I want to move to new part which is MMC version 5.0 compliant eMMC MTFC4GACAJCN-1M WT.

As per datasheet iMX6UL supports MMC version 4.4/4.5.

Can i use ver 5.0 compliant eMMC MTFC4GACAJCN-1M WT with iMX6UL processor.?

 

Seeking for help.

Thank you.

5.0 eMMC can be used, we are using 5.0 MTFC4GACAJCN-4M IT part on our i.MX 6ul/6ull board MYD-Y6ULX

Hello Ritesh Patel,

You should be able to use the eMMC 5.0 but none of the 5.0 specific features will be available. You would be using it as a eMMC 4.4/4.5. For this you would need to change the value of card->ext_csd.rev from 6 to 7. You may find more information on the thread below, it's not i.MX6UL specific but the logic would be the same.

i.mx6 with eMMC 5.0 SDR or DDR interface?

Regards,
