hello I would like created my own image nfi UBIFS extractor, but there is a dream sousi not use standard parameter is created that is how their UBIFS Image
"mkfs.ubifs -r /hdd/image/rootfs -o /hdd/image/rootfs.ubifs.img -m 2048 -e 126976 -c 1961 -x favor_lzo -F"  the-c option is problematic because what is set to 1961 should be 2048, is that someone has a solution


here is my complete script to extract a picture UBIFS

 

#!/bin/sh

MEDIA=media

KERNEL=`uname -r`
umount /tmp/ubi > /dev/null 2>&1

ln -s /hdd/image /image

/usr/vuplus-executeur/ubidetach -p /dev/mtd3 > /dev/null 2>&1

rmmod nandsim  > /dev/null 2>&1
mkdir /tmp/ubi > /dev/null 2>&1

cd /image
unzip *.zip
sleep 2

cd /hdd

if [ -f "swapfile" ]; then
	find swapfile | grep swapfile
else
	if [ -f "/dev/zero" ]; then
	        dd if=/dev/zero of=/media/hdd/swapfile bs=1024 count=132768
                sleep 2

Well it looks like you are not even understandig what -c the maxlebcount does. Please read ubifs FAQ

One more hint for a real solution (if you don't like my ubidump), instead of your 'borrowed' shellscript and playing around with nandsim:

bonjour,merci,sur pc linux sa fonctionne,mais sa ne marche pas sur enigma2 mipsel ,sa marque toujour cette erreur no module name lzo,pourtant le fichier lzo.so je l'ai trouvé en version précompilé est je l'ai installé ,ou il me manque un paquet pour les les python .so ? faut il un paquet suplémentaire pour les python .so


hello, thank you, it works on linux pc, but its not working on mipsel enigma2, brand Still this error no Module name lzo, yet lzo.so file I found is precompiled version I installed, or I'm missing a package for python. so? be it an aditional package for Python .so ?

[loulou2000]

there I found the solution, it is necessary to lzo.so in the python2.7 directory, against the image of the dream does not work

Nonsense, if you are not able to get the ubifs image out of the nfi it is not my fault.
