+* ----- ---- -------- -----------------------------------------------
+* 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
