Hello guys,
I have a small question. I've seem some images on the web, that uses the
format .jffs2 . Sometimes I just want to know what kind of files are inside
them instead of flashing my router all the way...
I've found this info on a blog:
$ mknod /tmp/mtdblock0 b 31 0
$ modprobe mtdblock
$ modprobe mtdram total_size=65536 erase_size=256
$ modprobe jffs2
$ dd if=/pathtoimage/rootfs.jffs2 of=/tmp/mtdblock0
$ mkdir /media/jffs2
$ mount -t jffs2 /tmp/mtdblock0 /media/jffs2
But I really wasn't able to reproduce this. On the last part I'm getting :
mount: wrong fs type, bad option, bad superblock on /tmp/mtdblock0,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
My system uses ppc and my computer is x86.
dmesg shows:
[ 1224.939358] jffs2: Flash size not aligned to erasesize, reducing to 0KiB
[ 1224.939364] jffs2: Too few erase blocks (0)
Does the mtdblock has to have the exact size of the jffs2 file or it can be
bigger? My jffs2 file has 198k (202060 as show by the ls -la command)
Thanks
Érico V. Porto
