Installing the Software

Note: You can uninstall these components by using the rm -rfcommand on its directory. You should ignore the uninstall files created by the installer.

4.3.3Installing the A/V Demo Files

The fourth disk contains the A/V files used by the demos. After following the instructions in the previous section, follow these instructions to install the A/V files:

1)Go to the demos directory in the DVSDK directory that you set up previously. For example:

host $ cd /home/<useracct>/dvsdk_#_#/dvsdk_demos_#_#_#

2)Mount disk 2 and copy the data.tar.gz file to your DVSDK directory. For example:

host $ cp /mnt/cdrom/data.tar.gz .

3) Extract the A/V data files. For example:

host $ tar zxf data.tar.gz

4.3.4Exporting a Shared File System for Target Access

Although the board’s NAND flash contains a file system, during development it is more convenient to have the target board NFS mount a file system on a host Linux workstation. Once you have tested the application, you can store it on the board’s flash for a standalone demonstration.

Before the board can mount a target file system, you must export that target file system on the host Linux workstation. The file system uses an NFS (Network File System) server. The exported file system will contain the target file system and your executables.

To export the file system from your NFS server, perform the following steps. You only need to perform these steps once.

1)Log in with a user account on the host Linux workstation.

2)Perform the following commands to prepare a location for the MontaVista file system. For example:

host $ cd /home/<useracct>

host $ mkdir -p workdir/filesys

host $ cd workdir/filesys
