 TFTP (Trivial File Transfer Protocol) is a simplified version of FTP (File Transfer Protocol),running on port 69. It can be setup with very litte effort.\\

 The first thing is to install install the client and the server package, together with xinetd superserver.
 <code>
 sudo apt-get install xinetd tftpd tftp
 </code>
 The next step is to create folder to act as TFTP root, the files for e.g. firmware updates on the Starterkit must be stored here .\\
 Typically this folder is located at the root level and named **tftpboot**
 <code>
 sudo mkdir /tftpboot
 sudo chmod -R 777 /tftpboot
 sudo chown -R nobody /tftpboot
 </code>
+Now a new xinetd tftp serivce has to be configured by creating the file **/etc/xinetd.d/tftp** :
+<code>
+sudo nano /etc/xinetd.d/tftp

-The default TFTP suite is tftp-hpa. To install the following step is needed:
-<code bash>
-user@ubuntu:~$ sudo apt-get install tftpd-hpa tftp-hpa

-The TFTP default directory is /var/lib/tftpboot.
-Change the following line in ''/etc/default/tftpd-hpa'' to point to the images directory of the BSP:
 <code>
-TFTP_DIRECTORY="/home/tq/workspace/TQMa6x-BSP-REV.0104/platform-MBa6x/images"
+sudo service xinetd restart

-==== Configuration ====
-To cofigure TFTP the file ''/etc/xinetd.d/tftp'' must be created and filled with the following content. This configuration uses the directory ''/tftpboot''.
-<code>
-service tftp
-{
-  socket_type             = dgram
-  protocol                = udp
-  wait                    = yes
-  user                    = root
-  server                  = /usr/sbin/in.tftpd
-  server_args             = -s /tftpboot
-  per_source              = 11
-  cps                     = 100 2
-}
