xscuwdt_polled_example.c File Reference

Overview

This file contains a design example using the Xilinx SCU Private Watchdog Timer driver (XScuWdt) and hardware device in watchdog mode.

This test illustrates how to initialize the watchdog device and restart it periodially to avoid the assertion of the WDRESETREQ pin.

Note

None.
