xhwicap_testapp_example.c File Reference

## Overview

This file contains a design example using the HwIcap device driver and hardware device.

Note

This example can be run on a 7 series device, Zynq device, Ultrascale and ZynqMP Ultrascale FPGAs.

In a Zynq device the ICAP needs to be selected using the XDcfg_SelectIcapInterface API of the DevCfg driver (clear the PCAP_PR bit of Control register in the Device Config Interface) before it can be accessed using the HwIcap. In case of ZynqMP clear the PCAP_PR bit of pcap_ctrl register in Module Configuration Security Unit(CSU) using register write.
