Before moving on to an fstab entry you need to make sure you can mount the partition manually, which it seems you can't do yet. I suspect that's because the partition isn't vfat. There are several ways you can check which filesystem type it's using - I'm not sure which will be present by default on PmOS but here are some you can try:
lsblk -f
blkid /dev/mmcblk0p2
sudo file -sL /dev/mmcblk0p2
These will also show you the UUID of the partition - this is what should go in the fstab entry, not the disk identifier you used.
