NAND Dump

Post by hamishmb »

I have successfully dumped the contents of the NAND flash. I have yet to interpret most of these, but I do hope to be able to mount the root filesystem so I can poke around a bit more soon. I am experiencing issues attaching these files, but I have attached as many as I can. These all sum to around 128 MB, so I assume the NAND's capacity must be 128 MB.

mtd0: Not sure what this is.

mtd1: Appears to be the kernel image, as reported by the "file" command.

mtd2: Appears to be the initrd, as reported by the "file" command.

mtd3: This is the biggest partition/segment, so I'm assuming this is the rootfs, but I don't know how to read it yet.

mtd4: Not sure what this is.

mtd5: Appears to be where persistent config is stored, as hinted at in /etc/rc.sh. Formatted as jffs2 and mounted at /usr/local/config

mtd6: Not sure what this is.

Attached are all the files that can be found in the core filesystems of the NAS when powered on. This is probably more useful than the mtd devices dump from before.

NB: I found a commandline tool called binwalk that might be useful here.
