+### Deployment (TFTP/NFS)
+
+NOTE: These instructions are based on Embedded Linux Wiki, [here](http://www.elinux.org/R-Car/Boards/Yocto#Loading_kernel_via_TFTP_and_rootfs_via_NFS). And a Debian (wheezy, ip: 192.168.30.70) is used as the host for this instructions.
+
+#### Instructions on the host
+1. Setup a TFTP server
+ 1. Install necessary packages
+ $ sudo apt-get install tftp tftpd-hpa
+ 2. Go to build directory, and copy kernel and DTB into TFTP server root (default server dir: /srv/tftp)
+ $ cd $AGL_TOP/build/tmp/deploy/images/porter
+ $ sudo cp uImage uImage-r8a7791-porter.dtb /srv/tftp
+ 3. Verify TFTP server is working
+ $ ls uImage
+ ls: cannot access uImage: No such file or directory
+ $ cd /tmp/
+ $ tftp 192.168.30.70
+ tftp> get uImage
+ Received 3583604 bytes in 0.2 seconds
+ tftp> q
+ $ ls uImage
+ uImage
+
+2. set NFS server
+ 1. Install necessary packages
+ $ sudo apt-get install nfs-kernel-server nfs-common
+ 2. Go to build directory, and extract the root file system into a dedicated directory (here we use /nfs/porter)
+ $ cd $AGL_TOP/build/tmp/deploy/images/porter
+ $ sudo mkdir -p /nfs/porter
+ $ sudo tar --extract --numeric-owner --preserve-permissions --preserve-order \
+ --totals --directory=/nfs/porter --file=agl-demo-platform-porter.tar.bz2
+ 3. Edit /etc/exports
+ $ sudo vi /etc/exports
+ Add
+ /nfs/porter *(rw,no_subtree_check,sync,no_root_squash,no_all_squash)
+ Save the file and exit.
+ 4. Restart nfs service
+ $ sudo service nfs-kernel-server restart
+ 5. Verify NFS server is working
+ $ sudo mount -t nfs 192.168.30.70:/nfs/porter /tmp/
+ $ ls /tmp
+ bin boot dev etc home lib media mnt proc run sbin sh-thd-430987335390 sys tmp usr var
+
+#### Instructions on the target board
+
+NOTE: There is details about porter board [here](http://elinux.org/R-Car/Boards/Porter).
+
+NOTE: To boot weston on porter board, we need keyboard and mouse. (USB2.0 can be use for this)
+
+##### Change U-Boot parameters to boot from TFTP/NFS
+
+1. Power up the board and, using your preferred terminal emulator, stop the board's autoboot by hitting any key.
+
+ > Debug serial settings are 38400 8N1. Any standard terminal emulator program can be used.
+
+2. Set the follow environment variables and save them
+ => setenv ipaddr <board-ip>
+ => setenv serverip <host-ip>
+ => setenv bootargs_console console=ttySC6,${baudrate}
+ => setenv bootargs_video vmalloc=384M video=HDMI-A-1:1024x768-32@60
+ => setenv bootcmd_net 'tftp 0x40007fc0 uImage; tftp 0x40f00000 uImage-r8a7791-porter.dtb'
+ => setenv bootcmd 'setenv bootargs ${bootargs_console} ${bootargs_video} ip=${ipaddr} root=/dev/nfs nfsroot=${serverip}:/nfs/porter,vers=3;run bootcmd_net;bootm 0x40007fc0 - 0x40f00000'
+ => saveenv
+
+ Replace <board-ip> with a proper IP address for the board, like 192.168.30.60.
+ Replace <host-ip> with the IP address of the host, here we use 192.168.30.70.
+
+##### Boot from TFTP/NFS
+
+1. After board reset, U-Boot is started and after a countdown, ...
+ Linux boot message should be displayed. Please wait a moment.
+2. Then weston is booted automatically, and weston-terminal appears.
+
+3. Have fun! :)
