Ok so have been trying to look some settings from a jffs2 partition I extracted from a nand dump I had done previously Here ----> https://forum.openwrt.org/viewtopic.php?id=67564
Steps I have preformed are as follows
convert from big endian to little endian
$ jffs2dump -r -e 1D0000_converted.jffs2 -b 1D0000.jffs2
Create the mtdblock devices
$ mkdir /dev/mtdblock
$ mknod /dev/mtdblock/0 b 31 0
$ mknod /dev/mtdblock/1 b 31 1
$ mknod /dev/mtdblock/2 b 31 2
Mount the Image
$ modprobe jffs2
$ modprobe mtdram total_size=8192 erase_size=128
$ modprobe mtdblock
$ dd if=1D0000_converted.jffs2 of=/dev/mtdblock/0
$ mkdir /mnt/jffs2
$ mount -t jffs2 /dev/mtdblock/0 /mnt/jffs2
Now when I browse to /mnt/jffs2 I can see all the files and directory's but i cant open any of the files i just get Could not open the file"mnt/jffs2/bank_1/etc/config/ethernet" Unexpected error: Error reading from the file: input/output error
