xdfeofdm_examples.c File Reference

Overview

This file contains the examples main function.

Note: MGT si570 oscillator is set to 152.25MHz by default. The DFE IP wrapper requires MGT clock to be set to 122.88MHz (some IP use 61.44MHz). Prerequisite is to set the MGT si570 oscillator to the required IP before running the example code. This is for the ZCU670 production platform.
