NOTE: Execute the above step1 or step2 only once. The configuration is persistent and is
retained after system reboot.
4.4.3 Starting the DSPs
After setting up the host, start the DSPs to load the image by executing the following
command:
# octService start all
The Octasic firmware images are stored at /var/lib/tftpboot/pcie8120 directory.
Now, the DSPs are taken out of reset. The DSP starts loading and executing the image. You can
check the tftpboot directory given above, to evaluate whether DSPs have successfully loaded
its image or not. The tftp load process is successful, if every DSP has stored its MAC address-
specific boot status file in tftpboot directory.
Also, the boot status file’s binary content can be analyzed to check error status, version
register, and progress counter. For more information, see Boot user guide listed in
Table "Related
Specifications" on page 91 .
Once the DSP firmware is loaded, you can execute the demo application.
4.5 Demo Application
Artesyn provides a demo application for PCIE-8120, setting up 400 IP to IP channels (800 IP end
points) per DSP, to transfer voice data from one DSP to another. The demo application monitors
all DSPs (one after the other) and evaluates its status by providing statistical data.
For more information with basic examples on configuring the DSPs with various codecs, refer
to Octasic SDK folder /opt/octasic/application/sample/octvoc.
Note: The demo is used to configure 12DSPs.
