how to do it?
 

[mag_box2]

i create it

 

mkdir /mnt/ubi
modprobe mtdblock
modprobe ubi

modprobe nandsim first_id_byte=0xec second_id_byte=0xa1 third_id_byte=0x00 fourth_id_byte=0x15


cat /proc/mtd
ls -la /dev/mtd*

dd if=rootfs.bin of=/dev/mtdblock0 bs=2048
ubiattach /dev/ubi_ctrl -m 0 -O 2048

ls -la /dev/ubi*

mount -t ubifs ubi0_0 /mnt/ubi/
