If you want to install your customized root file system quickly without destroying the
default one, you can put it on the second partition and modify the u-boot bootargs variable.
Now, let's see how we can do that !!!
First, we need to transfer the jffs2 root file system to the target.
Several possibilities are available:
By pluging a usb memory key containing the RFS on the MB-QIL-A9260 USB port or by
downloading it via tftp from a host.
Here is an example using a usb memory key
We can copy your root filesystem on a USB memory key and then mount it as it describes
below:
# mount -t vfat /dev/sda1 /mnt
#cp mnt/rootfs.arm.jffs2 /root
#umount /mnt
# ls -al
drwxr-xr-x
2 root root 0 Jan 1 00:02 .
drwxr-xr-x 16 rootroot 0 Jan 1 00:00 ..
-rw-r—r-- 1 root root 720 Jan 1 00:03 .ash_history
