How to update NELK

Info Box Applies to Naon Applies to DVDK

Introduction

This page describes how to perform the NELK update procedure, 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.

We assume that the DVDK provided with a previous kit version is already installed on the system

Installation Steps

The update package consists in a compressed archive (nelk-x.y.x.tar.bz2). It can be downloaded from 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
