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

-rw-r—r-- 1 root root 0 Apr 6 2007 .bash_history

-rw-r—r-- 1 root root 175 Apr 6 2007 .bash_logout

-rw-r—r-- 1 root root 161 Apr 6 2007 .bash_profile

-rw-r—r-- 1 root root 1711 Apr 6 2007 .bashrc

-rw-r—r-- 1 root root 2228224 Jan 1 00:02 rootfs.arm.jffs2
