My command is :

imx6qsabresd login: root
root@imx6qsabresd:~# mmc2: host does not support reading read-only switch. assuming write-enable.
mmc2: new high speed SDHC card at address 1234
mmcblk2: mmc2:1234 SA32G 28.9 GiB
mmcblk2: p1

root@imx6qsabresd:~# mount -t vfat /dev/mmcblk2p1 sd
FAT-fs (mmcblk3p1): Volume was not properly unmounted. Some data may be corrupt. Please run fsck.
root@imx6qsabresd:~#

Hi tom

it may be useful to look at attached Linux Guide for emmc numbering rules,

sect.4.7.1 Running Linux OS from MMC/SD, Table 31. Linux uSDHC relationships

Best regards
