Hello Ram, Thanks for the information. Xilinx is using "SD2.0/SDIO2.0/MMC3.31 AHB Host Controller" APM is using "SD3.0/SDIO3.0/eMMC4.41 AHB Host Controller" Sigma is using "SD3.0/SDIO3.0/eMMC4.4 AHB Host Controller" Rockchip is using ? (Shawn could you specify exactly which IP you use?) And it looks like Arasan is using different revision numbers for every documentation they have. The "SD3.0/SDIO3.0/eMMC4.4 AHB Host Controller" doc I have is at rev number 6.0, dated 2010-02-19.
