==== NFS Server ====
One of the most useful features of a bootloader during development is the capability to download the Linux kernel from the network. This saves a lot of time because developer doesn't have to program the image in flash every time he/she modifies it. U-Boot implements the TFTP protocol (see the tftp command), so the host system must be configured to enable the TFTP service. Installation and configuration of a TFTP server depends on the host Linux distribution.
The default DVDK tftp installation has <code>/srv/tftp</code> as work directory. A subdirectory dedicated to the image files associated to the DIVELK (<code>/srv/tftp/divelk</code>) is available, but developers can add their custom subdirectories when required.
