int WdtPsSelfTestExample

(

UINTPTR

BaseAddress

)

This function does a minimal test on the watchdog timer device and driver as a design example.

The purpose of this function is to illustrate how to use the XWdtPs driver.

This function may require some time (seconds or even minutes) to execute because it waits for the watchdog timer to expire.

Parameters

BaseAddress

contains the base address of the device

Returns

XST_SUCCESS if successful, otherwise XST_FAILURE.

Note

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