fstab not mounting partitions automatically

Question

When I create new partitions on the flash drive I'm finding that they are not being mounted at boot. Here is my fstab:

devpts                 /dev/pts      devpts    defaults            0      0
shm                    /dev/shm      tmpfs     nodev,nosuid        0      0
/dev/mmcblk0p1         /boot         vfat    defaults              0      0
/dev/mmcb1k0p4         /home         ext4    defaults              0      0

The new partition, /home does not get mounted.

Also, interestingly it fails to mount with:

$ sudo mount /home/
mount: special device /dev/mmcb1k0p4 does not exist

But this mounts fine:

sudo mount /dev/mmcb1k0p4 /home

Answer 1

Unbelievable, there is a typo here:

/dev/mmcblk0p1         /boot         vfat    defaults              0      0
/dev/mmcb1k0p4         /home         ext4    defaults              0      0
         ^

It should be an l not a 1.
