Running the Demos from the Command Line

3-10

3) Move to the appropriate directory on the target using the following

command. (See Section 4.1.1 for the meanings of command prompts
shown in this document.)

Target $ cd /opt/dvsdk/dm6446

4) Before running demo applications from the command line, the CMEM

and accelerator kernel modules must be loaded.

■ Use "lsmod" to see if they are loaded. You should see output

similar to the following:

Target $ lsmod

Module Size Used by

dsplinkk 98220 0

cmemk 20072 0

■ If they are not loaded, use the following commands to load these

modules.

Target $ ./loadmodules.sh

5) If a standalone demo is running, kill that process. You can do this by

pressing the Power button on the remote from the main menu. Or,
use the following commands:

Target $ killall -9 interface

6) To see the command-line options for the demos, use one of the

following commands with the -h or --help option:

Target $ ./encodedecode -h

Target $ ./encode -h

Target $ ./decode -h

7) To stop a demo, press Ctrl+C at the command line or press the Stop

button on the remote.

You can also find the list of command-line options in encode.txt,
decode.txt, and encodedecode.txt in the respective demo directories of
the DVSDK package on the host.

Note: When you run loadmodules.sh, you may see warnings about
the kernel being tainted by cmemk and dsplinkk. You can ignore
these warnings. They occur because DSP/BIOS Link does not use
the kernel build system and is not under the same license as the
kernel itself.
