About sdmmc3 on jetpack32.4.1 of jetson nano

I down the jectpack from 32.6.1 to 32.4.1 of jetson nano p3449-0002 on my custom board, then I change the dts enable sdmmc3 status to “okay”, but the sdcard cannot been detect.
The same modify can be effect on jectpack 32.6.1, I want to know, how to enable the sdcard on sdmmc3?;

From the beginning, this would not just work with setting sdmmc3 status to okay.
