This configuration is very helpful during the software development (both for kernel and applications). The kernel image is downloaded via <code>TFTP </code> while the root file system is remotely mounted via <code>NFS </code> from the host. It is assumed that the development host:* is connected with the target host board through an Ethernet ethernet LAN

* runs a TFTP server.

In any case, some variables has have to be configured on the target and the VM itself has to be configured for with respect to the network environment.

The [[DESK-XZ7-L]] Virtual Machine has the '''tftp''' and '''nfs''' services already running. Optionally, their configuration has to be changed according to the network configuration where to which the target is connected to.

The IP address for the server and target should be configured: as an example (for a network subnet <code>192.168.0.x</code>)

* <code>netdev</code> is the name of the ethernet interface of the target

For using the DVDK Virtual Machine, a static IP address configuration has been selected, to so the U-Boot variable <code>ip_dyn</code> has to be set to '''no''':

If you want saves Booting via <code>pxe</code> protocol is a very simple and efficient way to save a lot of time to update your kernel image or rootfs, you need to use boot via pxe protocol. In this case you need to download , the following artifacts will be downloaded from our [https://mirror.dave.eu/desk-xz-l/desk-xz7-l-1.0.1/ mirror] server or build built with [[DESK-XZ7-L/Development/Creating_and_building_the_Petalinux_project | Petalinux]], the following artifact:

* <code>rootfs.tar.gz</code>, this file has to be decompress decompressed in your host device directory <code>/home/dvdk/nfsroot</code>

For more information about boot and configuration file files see [[ DESK-XZ7-AN-0003:_using_PXE_protocol_for_boot | DESK-XZ7-AN-0003: using PXE protocol for boot]]

In the case of NFS Boot, RootFS the root file system is mounted through the <code>NFS </code> but the bootloader, while (FSBL, bitstream, U-Boot ) and kernel can be downloaded using various methods, for example with JTAG, micro SD or tftp server.

In order to To boot your target via <code>NFS</code>, you need to update your configuration file with the following command:
