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.
