This page describes how to installa a perform the NELK updateprocedure, starting from an existing DVDK installation and updating only the SDK (tools, sources and root file system) without creating a full new DVDK virtual machine.
{{ImportantMessage|text=We assume that the DVDK provided with a previous kit version is already installed on the system}}
= Installation Steps =
{{ImportantMessage|text=The update package consists in a compressed archive (nelk-x.y.x.tar.bz2). It can be downloaded from [http://www.dave.eu DAVE website] or it can be found on the NELK distribution (SD card or USB pen drive)}}
* Start the DVDK virtual machine
* Take a snapshot of the current VM state. This creates a sort of "backup" which can be used to restore the previous installation
* Fetch the nelk-x.y.x.tar.bz2 file. You have the following options:
** download it from inside the virtual machine (with a browser or file downloader);
** share the file from a shared folder on the host machine using the "Shared Folder" feature (you need to have the Virtual Guest extension installed, see [[VirtualBox Shared folders]]);
** share the file from a shared folder on the local network (you need to have a working network configuration, see [[VirtualBox Network Configuration]]
