Hello!

 

Is it possible to boot IMX6Q from Micron 64G eMMC 4.41 card (MTFC64GJDDN-4M IT)?

 

Boot process stops every time after reading Product name from CID Register (as a response on CMD2). A few microseconds after the eMMC card sends "MMC64G" string, CMD and CLK lines go LOW (as you can see in the picture below, 1 - CLK, 3 - CMD).

Are there any restrictions on size of the card? If no, what else can cause the problem?
