how to change SDMMC1 to use as SDIO Interface?

I want to connect emmc from sdio interface sdmmc1, how to do?
I found OEM Product say like this: SD (Primary SD Card). Can be used instead for SDIO
interface.
Thanks!

Hi, SDMMC1 port can only be set as SD card or SDIO, can’t be set to eMMC type. There is detail info about this in TRM, please refer to that: https://developer.nvidia.com/embedded/downloads#
