1.00b rpm  04/25/02 First release
1.00b sv   06/08/05 Minor changes to comply to Doxygen and coding guidelines
2.00a ktn  10/20/09 Updated to use HAL processor APIs, minor modifications
              as per coding guidelines and macros have been renamed to
              remove _m from the name.
3.4   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.

int XUartNs550_LowLevelExample ( u32 UartBaseAddress )

This function does a minimal test on the UART device using the low-level driver macros and functions.

This function sends data and expects to receive the data through the UART. A physical loopback must be done by the user with the tranmit and receive signals of the UART.

Parameters

UartBaseAddress is the base address of the UARTNS550 device and is the XPAR_<UARTNS550_instance>_BASEADDR value from xparameters.h.

Returns: XST_SUCCESS if successful, XST_FAILURE if unsuccessful.

Note: None.
