Introduction
-------------
This text document accompanies the SATA 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 SATA for its ability to perform
write access; read access and data TX/RX ability. The test application writes
a known pattern into the TX Buffer and then reads back and verifies the same.
The known pattern written into the memory is the incremental hexadecimal numbers. After 
transferring the entire memory area, this application reads them back and validates
the data read. If the data read does not match the expected pattern, this test
is declared failed. It is declared pass otherwise.


Procudure
----------
This test application assumes the SATA 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 --> SATA_PHY_SEQUENCE_20Mhz

load "BB_012_SATA_Test.out" file and run.
