 ====== NFS server ======
-===== Used version =====
+===== Tested with the following operating systems =====
-  * Ubuntu 10.04 x86 in vmware player
+  * Ubuntu 10.04 x86 in VMware Player
-  * Ubuntu 12.04 x86 in vmware player
+  * Ubuntu 12.04 x86 in VMware Player
+  * Ubuntu 14.04 x86_64 in VMware Player
+  * Ubuntu 16.04 x86_64 in VMware Player
 ===== Installation =====
+\\
 <code bash>
 user@ubuntu:~$ sudo apt-get install nfs-kernel-server
+</code>
+\\
+----
+===== Example Configuration for NFS boot =====
+\\
+Create a directory on the host root filesystem.
+<code bash>
+user@ubuntu:~$ sudo mkdir /nfs
+user@ubuntu:~$ sudo chmod 777 /nfs
 </code>
-===== Configuration =====
+Extract the content of root.tgz to your nfs directory.\\
-To access rootfs via NFS the following line must be added to the file ''/etc/exports''.
+root.tgz is located in:
+  * BSP download archive provided by TQ-Systems e.g. (TQMxx.BSP.SW.BIN.xxxx.tgz\TQMxx.BSP.SW.BIN.xxxx.tar\root.tgz)
+  * After building the BSP sources with PTXdist e.g. (../TQMxx-BSP-REV.xxxx/platform-MBxx/images/root.tgz)
+<code bash>
+user@ubuntu:~$ cd /nfs
+user@ubuntu:~$ sudo tar -xvf ~/workspace/TQMaxx-BSP-REV.xxxx/platform-MBaxx/images/root.tgz
+</code>
+Next step is to configure the ''/etc/exports'' file.
+Create an entry that contains the path to your nfs folder created above.
 <code>
-<Rootfs path on host system>       <permitted IPs>/<subnet>(<comma separated options>)
+<path/to/your/nfs/directory>       <permitted IPs>/<subnet>(<comma separated options>)
 </code>
-For example
+++++For example|
 <code>
-/opt/eldk-4.2/ppc_4xx               192.168.0.0/255.255.0.0(rw,no_root_squash,async,no_subtree_check)
+/nfs             192.168.0.0/255.255.0.0(rw,no_root_squash,async,no_subtree_check)
 </code>
+++++
-This path must match the variable ''rootpath'' of the U-Boot on the target. This variable is added to the boot parameter ''nfsroot='' and defines the source for the NFS rootfs.
+<WRAP round important>
+This path must match the U-Boot environment variable ''rootpath'' on the target and defines the source for the NFS rootfs.
+</WRAP>
 <WRAP round info>
-After this file was changed the NFS server should be restarted:
+After the /etc/exports file was modified the NFS server need to be restarted:
 <code bash>
 user@ubuntu:~$ sudo service nfs-kernel-server restart
 </code>
 </WRAP>
+----
 ===== Test the configuration =====
-With the command ''showmount'' you can see the exported directories if the NFS client programs (''sudo apt-get install nfs-common'') are installed on the system.
+\\
+With the command ''showmount'' you can see the exported directories.
 <code bash>
-user@ubuntu:~$ showmount -e 192.168.0.5
+user@ubuntu:~$ showmount -e localhost
-Export list for 192.168.0.5:
+Export list for localhost:
-/opt/eldk/ppc_6xx 192.168.0.0/255.255.0.0
+/nfs 192.168.0.0/255.255.0.0

 ===== Troubleshooting =====
+\\
 If the root file system cannot be mounted via NFS the log file of the NFS server should be checked. In Ubuntu the log is written to the file ''/var/log/syslog''.

 In this case the server rejects the connection because the host does not match the one in the file ''/etc/exports''.
-===== Configuration firewall / host system (NAT) =====
-NFS uses port TCP 2049. The configuration of Windows-XP as host system is descibed here: [[vm]].
