Error in mount

[crazygsm]

Hello,

Is not yet an issue with ubidump but in the steps to mount in order to could use it.

Was following the steps to perform the mount but I am struggling at this step.

1. Dumped full NAND using JTAG moving all content into RAM and after dumping into file.

2. Performing "strings" and HEX visualization seems correct dump

3. Trying to mount it as UBIFS but fails in last step.

Output.

mount: wrong fs type, bad option, bad superblock on /dev/ubi0_0,
missing codepage or helper program, or other error
(for several filesystems (e.g. nfs, cifs) you might
need a /sbin/mount. helper program)
In some cases useful info is found in syslog - try
dmesg | tail or so

Any one have any idea what I am doing wrong?
