Data Motion Network Clock

Every platform supports one or more clock sources, one of which is selected by default if you do not make an explicit choice. This default clock is defined by the platform provider, and is used for the data motion network generated by sdscc during system generation. You can view the platform clocks by selecting the Platform link in the General panel of the SDx Project Settings window. You can select a different platform clock frequency with the Data Motion Network Clock Frequency pull-down menu in the Options panel of the SDx Project Settings window, or on the command line with the -dmclkid option.

sdscc -sds-pf zc702 -dmclkid 1

To see the available clocks for a platform from the command line, execute the following:

    $ sdscc -sds-pf-info zc702
