→Installation Steps
* 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, and you need this because to do the update you need to remove the previous SDK (unless you have extended the disk space - see [[VirtualBox Extending Disk Size]])
* 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]];* Enter the '''sdk''' directory: <code>cd /home/shared/devel/dave/naon-DAA/sw/linux/sdk</code>* Remove the symbolic link to the root file system: <code>rm rfs/nelk</code>* Unless you have enough space available on the VM disk (you should have extended it following the [[VirtualBox Extending Disk Size]] guide), remove the previous sdk directory: <code>rm -fr sdk-x.xx.xx.xx</code>* Un-compress the archive: <code>sudo tar xvjf <path-to-update-archive>nelk-x.y.z.tar.bz2</code>. Include in the command the actual path to the nelk-x.y.x.tar.bz2 archive according on how you fetched it The new components ('''sdk-x.xx.xx.xx''' directory, '''rfs/nelk-x.xx.xx.xx''' root file system and '''rfs/nelk''' symbolic link) will be installed into the <code>/home/shared/devel/dave/naon-DAA/sw/linux/sdk</code> directory.
