Hi all, I'm also trying to mount a YAFFS2 dump (Samsung GalaxyS2) on ubuntu and I only managed to see the lost+found directory. Here is what I've done, following Luca's posts: - recompile the kernel with yaffs enable - load modules (mtdblock, mtd, nandsim) - nandwrite my image on /dev/mtd0 (-p only ; error with -o : is this a sign ?) - mount /dev/mtdblock0 Then I tried to replace in my kernel the drivers/mtd/nand directory with the one I got from samsung GalaxyS2 sources. Same result. Then I tried to replace the whole mtd directory but then I can't even load mtdblock module... I checked my dump : Page 2048 Bytes + 64 bytes of spare area. Someone has already succeeded in mounting a YAFFS2 dump on ubuntu ? thanks for any help Matthieu
