Hello, 

I try another method :

flash_eraseall /dev/mtd0


# ubiattach /dev/ubi_ctrl -m 0    # <- on mtd0 / rootfs

ubimkvol /dev/ubi0 -N rootfs -s 243 MiB -t dynamic


# ubiupdatevol /dev/ubi0 /rootfs.ubifs
ubiupdatevol: UBI volume node not in correct format

or 

# ubiupdatevol /dev/ubi0_0 /rootfs.ubifs
ubiupdatevol: UBI_IOCVOLUP: Invalid argument


# ubiupdatevol /dev/ubi0_0 /rootfs.ubifs -t     
this seems to pass (?)

the mount : 
mount -t ubifs /dev/ubi0_0 /mnt
[  905.704000] UBIFS error (pid 2344): init_constants_early: too few LEBs (1),
min. is 17
mount: mounting /dev/ubi0_0 on /mnt failed: Invalid argument

Can you help me ? How can I change the LEBs ?  


The method used to create the  images :
echo "
[ubifs]
mode=ubi
image=rootfs.ubifs
vol_id=0
vol_size=243MiB
vol_type=dynamic
vol_name=rootfs
vol_flags=autoresize
" in the file  ubinize.cfg

On the pc host : 

sudo mkfs.ubifs -v -r rootfs -o rootfs.ubifs -m 2048 -e 126976 -c 1936  
 -> this create the rootfs.ubifs

sudo ubinize -v -o rootfs.ubi -m 2048 -p 128KiB -s 512 ubinize.cfg
 -> this create the rootfs.ubi with rootfs.ubifs and ubinize.cfg
