Hi

 

Sorry, I didn't know that.

 

First picture is in i.mx6 soloX Reference Manual Page 385 (Chapter 8.5.3.1)

 

Second picture is in i.MX Linux Release Notes Rev.L5.4.70_2.3.0-31 December 2020 Page 26~32

( I extracted the one that is related to mmc and emmc)

 

 

My question is still same.

MMC vs eMMC is confusing in documents.

and what does the red box mean in second picture?

Hi,

Do you have AVL(alternate vendor list) for the emmc? or can i use any emmc part?

The part in the reference design MTFC8GLCDM is obsolete.
