/dev/mmcblk0 is the ***root of the (raw) device***.
/dev/mmcblk0p0 is the first partition
/dev/mmcblk0p1 is the second partition
etc.

Which is correct and specific - the ***root of the (raw) device*** is
not intended to be opened with VFS.
Put **at least** one partition on the storage device, use it for your
file system root (not device root).
