eMMC5.0 connection to iMX6's SD4 port

Hello,

We are connecting eMMC 5.0 memory (64GB from Sandisk) to iMX6's SD4 port. The Sandisk part has RCLK (STROBE) output pin. I've couple of questions:

 

1. Can I configure/force the Sandisk part to run at eMMC4.41/SDR/HS200 speed? From another post someone confirmed that you can't run eMMC5.0 HS400 mode with iMX6

 

2. Seems like the STROBE output from eMMC5.0 memory is only used in HS400 mode. Can i make STROBE output as No Connect (ie float this pin on the Sandisk memory)

 

We've no intention to use all the bells and features of this eMMC 5.0 part. We just want it to work as a standard eMMC part in 8-bit mode

 

I've attached the eMMC5.0 datasheet from Sandisk

 

Thanks for your help in advance!
