Introduction
-------------
This text document accompanies the uart-0 CCS test case for DM814X EVM. It 
provides a brief of the methodology of the test and the procedure for executing 
the same.

Overview
---------
This CCS test application validates the UART-0 Port on the board for its connectivity.
This test configures the UART-0 for 115200,8,N and verified the transmission & 
receiption functionality in polled mode. This test case requries the external
loop-back cable to be connected to the UART-0 port (that is connector P2 - DM814X DB9)
on the DM814X EVM Base board.

Procudure
----------
This test application assumes the DDR controller initialization as well as all
the PLL initialization is already carried out by the GEL scripts. At the minimum
the following GEL scripts are to be executed.
	1. PG 2.x DM814X --> ALL_ADPLL_CLOCKS_ENABLE_API
	2. DM814X System Initialization --> UARTClkEnable

load "BB_007_UART_0_Loopback.out" file and run.


NOTE: 
-----
 Ensure that BOOT SEL Switches (S1) are set as follows:
	BOOTMODE[1]: OFF
	BOOTMODE[2]: ON
	BOOTMODE[3]: OFF
	BOOTMODE[4]: OFF
	BOOTMODE[5]: ON
	BOOTMODE[6]: OFF
	BOOTMODE[7]: ON
