1. Overview
===========
The text file contains procedure used for testing IPIPE driver for DM350 EVM

2. Covered testing scenarios
============================
Following section of the file contains source file name, corresponding test case IDs and procedure to execute it.	


How to load IPIPE Driver as a loadable module
==================================================	
Steps :
	1) Compile the driver to make dm350_ipipe.ko file
	2) Run command : insmod dm350_ipipe_driver.ko
	3) Check the driver by running "cat /proc/devices" and node down the major number.
	4) Make nodes using above major number by following commands:
		A)mknod /dev/dm350_ipipe c <major no.> 0
		
	Now driver is loaded as a loadable module.We can have application running now.

  Explanation : This is the basic test of all the IOCTLs .
  Note :Make sure a raw file with name "raw16.bin"(624 * 456)is there in present working directory.
  			It makes a yuv file with name "yuv16.yuv"(640 * 480)

 === 
  Explanation : This  converts 8bit raw file named "bayer_book.h"(640 * 480) to yuv name "yuv16.yuv"(640 * 480) using RZA
  Note :Make sure an 8bit raw file named "bayer_book.h" is there in present working directory.
  			It makes a yuv file with name "yuv16.yuv"(640 * 480)

 === 
  Explanation : This converts 16bit raw file to yuv upscaling it using RZA
  Note :Make sure a 16bit raw file with name "raw16.bin"(624 * 456)is there in present working directory.
  			It makes a yuv file with name "yuv16.yuv"(640 * 480)
