+*
+* This file contains a design example using the UartLite driver (XUartLite) and
+* hardware device using the polled mode.
+*
+* @note
+*
+* The user must provide a physical loopback such that data which is
+* transmitted will be received.
+*
+* MODIFICATION HISTORY:
+*
+* Ver Who Date Changes
+* ----- ---- -------- -----------------------------------------------
+* 1.00a jhl 02/13/02 First release
+* 1.00a sv 06/13/05 Minor changes to comply to Doxygen and coding guidelines
+* 2.00a ktn 10/20/09 Updated this example to wait for valid data in receive
+* fifo instead of Tx fifo empty to update receive buffer
+* and minor changes as per coding guidelines.
+* 3.2 ms 01/23/17 Added xil_printf statement in main function to
+* ensure that "Successfully ran" and "Failed" strings
+* are available in all examples. This is a fix for
+* CR-965028.
+* 3.9 gm 07/08/23 Added SDT support
