One of the most useful features important components of a bootloader during development Linux system is the capability to download root file system. A good development root file system provides the Linux kernel from developer with all the networkuseful tools that can help developers on their work. This saves Such a lot of time because developer doesnroot file system can become very big in size, so it't have s hard to program store it in flash memory. User could split the image file system in different parts, mounting them from different media (flash every time he/she modifies it, network, usb...). U-Boot implements But the most convenient thing is to mount the TFTP protocol (see whole root file system from the tftp command)network, so allowing the host system must and the target to share the same files. In this way, developers can quickly modify the root file system, even “on the fly” (meaning that the file system can be configured modified while the system is running). The most common way to enable setup a system like the one described is through NFS (Network File System). As for TFTP service. Installation , installation and configuration of a TFTP server depends on the host Linux distribution. The default DVDK tftp NFS installation has is configured for sharing <code>/srvhome/dvdk/tftpdivelk</code> as work directory. A subdirectory dedicated to the image files associated to and all the DIVELK (<code>/srv/tftp/divelk</code>) is available, but developers can add their custom subdirectories when required.
