Why do i see, can't find in /etc/fstab.

Why do I see the can’t find in /etc/fstab error when I enter mount /dev/mmcblk on my BeagleBone Black terminal?

root@BeagleBone:/home/debian# mount /dev/mmcblk
mount: /dev/mmcblk: can’t find in /etc/fstab.

Please help me to resolve this issue.

You have the command wrong.
The emmc/asd card devices are named


Where X = the device and Y = the partition

If there is no entry in the fstab file for the partition you are trying mount, you also need to specify the mount point.
