First, install all the necessary packages:

sudo apt-get install xinetd tftpd tftp -y

Uncompress the rootfilesystem into a folder: (check the files name when you are creating the soft link, the uImage name may change, and change devel with your username)

mkdir /home/devel/rootfs-target-folder sudo tar -xvjf core-image-minimal.tar.gz -C /home/devel/rootfs-target-folder cd /home/devel ln -s rootfs-target-folder rootfs

Next, create a configuration file:

sudo nano /etc/xinetd.d/tftp

Put the following content into the file (change devel with your username)

service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = nobody server = /usr/sbin/in.tftpd server_args = home/devel/rootfs/boot -s disable = no }

and start the TFTP service:

sudo service xinetd restart

Set up the NFS

Install the following packages:

sudo apt-get install nfs-kernel-server portmap

and edit the file

sudo nano /etc/exports

Write this into the file (change devel with your username)

/home/devel/rootfs *(rw,sync,no_root_squash,no_subtree_check)

and execute

sudo exportfs -a

Check the bootserver IP address

Start the module

Stop the autoboot

setenv nfsroot '/home/devel/rootfs' setenv serverip '10.11.x.y' # IP address of the bootserver setenv netargs 'setenv bootargs console=${console},${baudrate} root=/dev/nfs ip=dhcp nfsroot=${serverip}:${nfsroot},v3,tcp video=mxcfb0:dev=${vid_dev0}' saveenv

If you want to boot a different rootfs, you can create another folder to uncompress the rootfs there, remove the soft link /home/devel/rootfs and create a new one pointing to the folder you want
