I am using custom carrier board with sdcard slot having jetson nano emmc module.
I am using 128 GB Sdcard but unable to detect sdcsrd via using df -h or lsblk.

I found error using dmesg:

mmc1: card never left busy state

Do i need to make changes in the dtb file for enabling sdcard slot ?

Did you configure device tree setting for your slot?

If you didn’t do that, search sdmmc3 in this forum and there are already lots of posts.
