Hello Lakh,

TI does not support PRUSS development on C674x/OMAP-L13x devices at this point in time. A long time ago there was a Linux OMAP-L138 driver to control PRUSS that was documented on the Processors wiki, but all that documentation is now offline.

It looks like the C674x RTOS SDK 6.3 (https://www.ti.com/tool/download/PROCESSOR-SDK-RTOS-OMAPL138) documents a PRUSS driver, but that driver was developed for processors with a full PRU-ICSS like AM335x, AM437x, AM57x. I am not sure whether the PRUSS driver supports initializing and interacting with C674x PRUSS. That SDK documentation is probably where you want to start to see if there are any examples:
