Total wild guess here ... based on my own experience.
Partition 4 missing is caused by either
a) not enough space on the device to create it or
b) you did not specify it as a primary partition.
I'm guessing that you made partition 3 too big, that is why you don't have partition 4.
Partition 3 should be about 1.1 GB, just big enough to hold partition 5, 6, 7, 8 and 9.
Partition 4 should be the rest of the storage device.
see this post (viewtopic.php?f=11&t=1153
Without partition 4, your mount points are off. They are defined in a file called freescale.fstab.
do a fdisk -l /dev/sdb
and post the result
Like I said, this is a total guess.
