I have 1:1 dump from 1GB NAND which is UBI format. But it contains JFFS part also. This part can be downloaded from my server. www.pouchx.com/PRV/HDS/K9G8G08U0M_Samsung_1GB_NAND_Config.ini_block_JFFS.rar Archive contains two files. One is original JFFS copy, second is same file but I deleted ECC blocks. I mount jffs image (noECC) with this script: $ sudo apt-get install mtd-tools $ sudo modprobe -v mtd $ sudo modprobe -v jffs2 $ sudo modprobe -v mtdram total_size=8192 erase_size=256 $ sudo modprobe -v mtdchar $ sudo modprobe -v mtdblock $ sudo dd if=/HDS/Config.img of=/dev/mtd0 $ sudo mount -t jffs2 /dev/mtdblock0 /HDS/JFFS After that I can see all 3 files that are in jffs image: can_unique_id Config.ini MAC I make no changes to these files. That I want to make new image from mounted device. I use this command: $ sudo mkfs.jffs2 -r /HDS/JFFS -o /HDS/newimage.jffs2 -e 256 -l Output file is only 696bytes. www.pouchx.com/PRV/HDS/newconfig2.zip Can anyone help me with this. How can I get same image as original one? In the future I want to edit Config.ini but now I just want to test that I will be able to create correct and working image. Jakub
