Pjoject Name:	21262 POST ATE

Date Modified:	11 May 2006

Software:		VisualDSP++ 4.5

Hardware:		ADSP-21262 EZ-KIT Lite

Connections:

Purpose:		Purpose:		Perform a POST ATE on the 21262 EZ-Kit Lite


21262 EZ-KIT board test indicators 	(version 1.00.0 11 May 2006)


Enter 21262 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
PBLED			0		1		0		0
SRAM			1		1		0		0
AM29LV081B		0		0		1		0
AT25F2048		1		0		1		0
ANALOG_AUDIO	0		1		1		0	SW11 All on
DIGITAL_AUDIO	1		1		1		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:
	- SW6 = OFF,OFF,OFF,OFF
	- SW7 		1 = OFF, 2 = ON, 3 = ON,  4 = ON
	- SW9 		1 = ON,  2 = ON, 3 = ON,  4 = ON,  5 = OFF,  6 = OFF
	- SW10 		1 = OFF, 2 = ON, 3 = OFF,  4 = ON
	- SW11 		All ON
	- SW12= ALL ON

Enter USB EZ-Extender POST test by pressing SW3 along with SW4

Test indicators are as follows:

			LED1	LED2	LED3	LED4
USB			1		0		0		0

NOTE:  	This test disables the LED's, so the acutal LED pattern may vary.  The
		indication of a pass/fail should be the data returned by the usb hostapp.exe


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:

	SW6 = OFF,OFF,OFF,OFF
	- SW7 		1 = OFF, 2 = ON, 3 = ON,  4 = ON
	- SW8 		All ON
	- *SW9 		1 = OFF,  2 = OFF, 3 = ON,  4 = ON,  5 = OFF,  6 = OFF
	- SW10 		1 = OFF, 2 = ON, 3 = OFF,  4 = ON
	- SW11 		All ON

Settings for the USB EZ-Extender:
	- JP1:	not installed
