→Target configuration for the development stage (net_nfs)
===Target configuration for the development stage (<code>net_nfs</code>)===
{{ImportantMessage|text=The default DIVELK Virtual Machine network configuration is using NAT: this allows to accessing external network (i.e. Internet) using the host computer's networking connection.
For software development using <code>net_nfs</code> with tftp/nfs protocols, please configure your VM network interface in ''Bridge mode'' (see below)}}
During the development stage, the target is usually connected via Ethernet LAN to the host machine and is configured to:
*retrieve binary images (i.e. Linux kernel) via TFTP protocol
*mount the development root file system via NFS protocol. This root file system is physically in the file system of the host machine as depicted [[Deploying_Embedded_Linux_Systems#The_development_environment|here]].An example of ''Bridge mode'' configuration can be found [[Booting_the_system_via_NFS_(DIVELK) | here]]
In DAVE Embedded Systems development kits, this configuration is generally denoted as <code>net_nfs</code>. U-Boot bootloader supports this configuration. Some U-Boot environment variables are needed to set it up.
