To be honest, I'm still very much in the dark about what I have installed, I'm just trying to find my way round it.
I tried the above commands suggested and got:-

To be honest, I'm still very much in the dark about what I have installed, I'm just trying to find my way round it.
I tried the above commands suggested and got:-
mkdir -p /tmp/nand/
mount -t ubifs /dev/mtdblock3 /tmp/nand/
mount: wrong fs type, bad option, bad superblock on /dev/mtdblock3,
missing codepage or helper program, or other error
ubiattach /dev/ubi_ctrl -m 3
ubiattach: error: cannot attach mtd3
error 19 (No such device)

And this means you don't have mtd3.
In all *nix systems (Arch, Debian, BSD,...), when in doubt, get help:
ubiattach --help

ubiattach version 2.0.0 - a tool to attach MTD device to UBI.
Usage: ubiattach [<UBI control device node file name>]
[-m <MTD device number>] [-d <UBI device number>] [-p <path to device>]
[--mtdn=<MTD device number>] [--devn=<UBI device number>]
[--dev-path=<path to device>]
[--max-beb-per1024=<maximum bad block number per 1024 blocks>]
UBI control device defaults to /dev/ubi_ctrl if not supplied.
Example 1: ubiattach -p /dev/mtd0 - attach /dev/mtd0 to UBI
Example 2: ubiattach -m 0 - attach MTD device 0 (mtd0) to UBI
Example 3: ubiattach -m 0 -d 3 - attach MTD device 0 (mtd0) to UBI
and create UBI device number 3 (ubi3)
Example 4: ubiattach -m 1 -b 25 - attach /dev/mtd1 to UBI and reserve
25*C/1024 eraseblocks for bad block handling, where C is the flash
is total flash chip eraseblocks count, that is flash chip size in
eraseblocks (including bad eraseblocks). E.g., if the flash chip
has 4096 PEBs, 100 will be reserved.
-d, --devn=<number> the number to assign to the newly created UBI device
(assigned automatically if this is not specified)
-p, --dev-path=<path> path to MTD device node to attach
-m, --mtdn=<number> MTD device number to attach (alternative method, e.g
if the character device node does not exist)
-O, --vid-hdr-offset VID header offset (do not specify this unless you really
know what you are doing, the default should be optimal)
-b, --max-beb-per1024 maximum expected bad block number per 1024 eraseblock.
The default value is correct for most NAND devices.
Allowed range is 0-768, 0 means the default kernel value.
-h, --help print help message
-V, --version print program version
To list the mtds
cat /proc/mtd

I tried all the options I could find for ubiattach but couldn't get anything to work.
