Project Name:	21369/21375 POST ATE

Date Modified:	11 May 2006

Software:		VisualDSP++ 4.5

Hardware:		ADSP-21369/21375 EZ-KIT Lite

Connections:

Purpose:		Purpose:		Perform a POST ATE on the 21369/21375 EZ-Kit Lite


21369 EZ-KIT board test indicators 	(version 1.00.0 11 May 2006)


Enter 21369/21375 EZ-KIT POST test by pressing PB4.  All other LEDs not shown below do
not matter and may be on or off.

				LED1	LED2	LED3	LED4
VERSION			1   	0   	0   	0
SRAM			0		1		0		0
SDRAM			1		1		0		0
UART			0		0		1		0	SW6 All on
AM29LV081B		1		0		1		0
AT25F2048		0		1		1		0
ANALOG_AUDIO	1		1		1		0	SW14 All on
DIGITAL_AUDIO	1		0		0		0




The switch settings for the built in self test differ slightly from the default settings shipped.
See the users manual for default switch settings.
Switch settings:
	- SW1  		All OFF
	- SW2  		1 = ON,  2 = OFF, 3 = ON,  4 = ON
	- SW3 		1 = OFF, 2 = ON,  3 = ON,  4 = ON
	- SW4 		All OFF
	- SW5 		1 = OFF, 2 = ON,  3 = OFF, 4 = ON
	- SW6 		All ON
	- SW7 		All ON
	- SW13  	1 = ON,  2 = ON, 3 = OFF,  4 = OFF,  5 = OFF,  6 = OFF
	- SW14 		All ON

Enter USB EZ-Extender POST test by pressing PB3 along with PB4

Test indicators are as follows:

			LED1	LED2	LED3	LED4
USB			1		0		0		1

The switch settings for the built in self test for the USB EZ-Extender differ slightly from the default
settings shipped.  The "*" indicates the only setting that is different from the normal
POST settings above.  See the users manual for default switch settings.
Switch settings:
	- SW1  		All OFF
	- SW2  		1 = ON,  2 = OFF, 3 = ON,  4 = ON
	- SW3 		1 = OFF, 2 = ON,  3 = ON,  4 = ON
	- SW4 		All OFF
	- SW5 		1 = OFF, 2 = ON,  3 = OFF, 4 = ON
	- SW6 		All ON
	- *SW7 		1 = OFF, 2 = OFF, 3 = ON,  4 = ON
	- SW13  	1 = ON,  2 = ON, 3 = OFF,  4 = OFF, 5 = OFF, 6 = OFF
	- SW14 		All ON

Settings for the USB EZ-Extender:
	- JP1:	installed
