xuartps_polled_example.c File Reference

Overview

This example runs on zynqmp evaluation board (zcu102), it sends data and expects to receive the same data through the device using the local loopback mode in polled mode by using XUartPs driver.

Note

If the device does not work properly, the example may hang.

int UartPsPolledExample	(	XUartPs *	UartInstPtr,
		UINTPTR	BaseAddress
	)

This function does a minimal test on the XUartPs device in polled mode.

This function sends data and expects to receive the data through the UART using the local loopback mode.

Parameters

BaseAddress

contains the base address of the device

Returns

XST_SUCCESS if successful, XST_FAILURE if unsuccessful

Note

- In XSCT/classic flow, DeviceId is used to look up the device configuration.

• This function polls the UART, it may hang if the hardware is not working correctly.
