imx6 duallite support eMMC 100MHz DDR?

[westbrook]

Hi, guys

Currently, I am using imx6 dual lite processor, eMMC works at 52MHz/DDR mode(acctually 49.5MHz). Is it possible that I change the imx6 uSDHC to work at 100MHz DDR mode(actually 99MHz)?

I noticed that imx6 dual lite does not support HS200, howerver, is 100MHz DDR possible on imx6 dual lite?

Thank you in advance!

BR,

Xiao

Hi xiao

emmc features are described in 4.11.4 Ultra High Speed SD/SDIO/MMC Host Interface (uSDHC) AC
Timing i.MX6SDL Datasheet, it supports only eMMC4.4/4.41 Dual Date Rate 52MHz.
