I know if it’s the same way as in Jetpack 4.6.x.
But if the method is different in Jetpack 5.x, shouldn’t it be solved by asking a question?
Is it possible to recognize the sdcard in Jetpack 5.x in the same way as in Jetpack 4.6.x?
The method should be same but we didn’t validate. NVIDIA does not have any NX custom board which has sdmmc3 enabled with sdcard.
You can share your dmesg, schematic and dts file here to check. My point is sharing these information should be the basic but not asking me which file to modify. You have been here for almost 2 years. So I think sharing these information should be a common sense to you.
