One of To start developing software for the most important components of DIVA platform, users need a Linux system is the root file system. A good development root file system provides the developer with all the useful tools that proper toolchain, which can help him/her on his/her workbe pre-built or built-from-scratch. Such Building a toolchain from scratch is not a root file trivial task (though using a recent build system can become very big is easier than in sizethe past), so it's hard to store it the recommended approach consists in flash memoryusing a pre-built toolchain. User could split DIVELK provides the file system in different parts, mounting them from different media (flash, network, usbLinaro gnueabihf-4.7-2013..). But the most convenient thing is to mount the whole root file system from the network, allowing the host system and the target to share the same files. In this way, the developer can quickly modify the root file system, even “on the fly” 03 toolchain (meaning that the file system can be modified while the system GCC version is running)4.The most common way to setup a system like the one described is through NFS7. As for TFTP, installation and configuration depends on the host Linux distribution. The default DVDK NFS installation is configured for sharing <code>/home</code> directory and all the subdirectories3).
