-p 512KiB: to set the physical eraseblock size of the flash chip;
-s 1024: to indicate that the flash supports sub-pages and sub-page
size is 1024 bytes;
About the generated UBIFS [5], it is important to note that the command df
does not get the same results as with EXT2 or EXT3. The flash space reported
by tools like df is probably wrong, since UBIFS makes pessimistic calculations
and reports its size as the absolutely minimum amount of space which it can fit
in the worst case scenario.

The user can copy the filesystem that is currently in the owa4x executing the
following command:
tar --exclude="/dev" --exclude="/run" --exclude="/tmp"
--exclude="/temp" \ --exclude="/proc" --exclude="/mnt"
--exclude="/sys" \ --exclude="/lost+found" \
--exclude="/etc/udev/rules.d/70-persistent-net.rules" \
--exclude="/etc/device.info" --exclude="/etc/pmsrv.info" \
--exclude="/var/log" –exclude="/var/lib/bluetooth" \
--exclude="/var/lib/dhcp" –exclude="/var/tmp" \
--exclude="/etc/ssh/ssh_host_*" -cpzf \ ./rootfs.tar.gz /
And extract it with this command:
$ sudo tar --same-owner -zxvf rootfs.tar.gz -C rootfs
The original /etc/udev/rules.d/70-persistent-net.rules file should be
copied in the rootfs folder to avoid using the same MAC address on multiple
devices.

In case of failure or misconfiguration of the Debian file system, a recovery
image can be started. The purpose of this is to mount the Debian partition and
to solve its problems, in order to be able of starting it again.
To load the recovery image, enter the u-boot prompt and type these commands:
setenv nandroot "ubi0:rootfs rw ubi.mtd=NAND.file-system.backup1,1024"
boot
Once booted, check partitions:
cat /proc/mtd
If the file /dev/ubi_ctrl doesn't yet exist, it has to be created using mknod. The
correct parameters should be read from /sys/class/misc/ubi_ctrl/dev.
cat /sys/class/misc/ubi_ctrl/dev
mknod /dev/ubi_ctrl c 10 58
