Setting up the System

WLAN Network map

Different scenarios can be used for the WLAN demonstration.

Access Point configuration

In this configuration you need both Computer and EVM board to be connected on the same network through a Wireless Access Point.

Note: Using WLAN interface of the computer to connect to the network can reduce the performance due to a reduced Bandwidth.

Point to Point configuration

This “standalone” configuration allows you to connect to an ad hoc network hosted on your Computer from the EVM board, without the requirement of a network Wireless Access Point. In fact your computer is acting as an AP.

In this configuration you will have to set manually the IP Address of both wireless interfaces, the one on the laptop, and the one on the EVM. Refer to paragraph 3.2 Setting Up the Host Computer for IP Address configuration

Setting Up the Host Computer

The Host computer must be a PC running Windows XP that supports telnet client application

Change the local IP address according to the network configuration you desire.

Setting Up the Target System

The OMAP3 EVM development has a number of possible combinations for a number of hardware interfaces. These combinations are determined by the definitions of the jumper settings and a dip switch.

DIP Switch Settings

The OMAP3530 processor supports various boot modes. On the OMAP3530 development boards, the boot modes are selected by setting various dip-switch combinations. On the OMAP3 EVM development board, this switch is labeled SW4. The dip switch settings for the various boot modes are as follows:

Table 1: MMC/SD Boot

	1	2	3	4	5	6	7	8
OMAP3EVM With Micron NAND	ON	ON	ON	OFF	OFF	ON	OFF	OFF

Setting Up the WLAN DC Hardware

To setup the WLAN DC hardware:

1. Mount the daughter card as shown below:

The following shows the picture of the daughter board on its own.

2. Check that jumper J8 is connected between terminal 1 and 2 in order to enable normal use, as shown below:

3. Check that jumper JP2 is connected. This jumper is only used if the board is modified to power up from the USB connectors, as shown below:

4. Verify that jumpers J2 and J3 are not connected, as shown below:

5. Check that jumper JP1 is either not connected or connected between 1-2 for normal use, as shown below:

To setup the WLAN IP Address:

1. To change the IP Address, open the Start -> Settings -> Network and Dial-up Connections

2. Select the network interface (SMSC91181) in the list and choose File -> Properties menu

3. Enter an IP address

Loading the Images

Setting Up the Hardware for Loading

To load the images to the SD Card

1. Preparing the SD Card to be bootable on the EVM: Use SD card boot utility Install the TI_SDCard_boot_utility_v1_0.exe that can be found in X:\WINCE600\3rdParty\TI_ECS\Images\SDCard_boot_utility folder in the SW distribution.

Step 1. Run the installed utility

Step 2. Select the SD card drive

Step 3. Browse and Select the MLO file

Step 4. Browse and Select the EBOOTSD.NB0 and NK.BIN files

Step 5. Click Proceed.

Click "Start" to format the SD card

Click "OK" for Format Warning

Click "OK" once "Format Complete" window pops up

Click "Close" to close the format window

Click "Quit" once the files are copied

Note: binaries (MLO, EBOOTSD.nb0 and NK.BIN) are located in X:\WINCE600\3rdParty\TI_ECS\Images. This document is assuming you have read the user guide.

Starting to Load

The following procedure describes how to start loading the Kernel WLAN and BT images. To start loading the Kernel (nk.bin):

1. Connect the OMAP35x EVM to the power supply

2. Wait until the Kernel finishes booting up.

Bluetooth Only Demos

Start serial test application

Switch to the Windows CE desktop, and launch the Serial Test application. Enter the serial port number identified at step 3. And hit the Open button.

Start serial terminal application

Under Windows, start a TeraTerm application and connect to the Bluetooth Serial Port enabled after Windows CE Target Bluetooth connection

Send data in both directions

1. From Windows CE, type keys on the bottom edit area and hit send

2. Check out the result on the Laptop.

3. Do the same from the laptop by typing in the Tera Term Window. No echo is displayed in the Tera Term window, so you cannot see what you are typing.

WLAN Only Demos

This chapter describes the WLAN scenarios. For all the scenarios, we are assuming that the board is powered on and the touch screen aligned.

Pre-requisite

Pre-requisites for all the demos are described above

Connecting to a Unsecured WLAN Network

To connect to an unsecured WLAN network GUI:

2. Select the desired network and hit the connect button.

To connect to an unsecured WLAN network from ZeroConfig Tool:

Verifying the Connection to the Access Point

A simple ping test can be used to verify the connection to the access point.

To verify connection with the access point:

1. Use the hardware setup to run the ping test:

2. Configure the EVM WLAN IP address and make sure that the EVM Ethernet port and WLAN port do not share the same IP subnet address.

Note: To change the IP Address of the WLAN interface, follow the instructions for 4.1Setting Up the Hardware for Loading, but select TIWLNAPI1 network interface instead of the SMSC one.

3. Verify that the WLAN interface (tiwlnapI1) IP address is configured correctly, as shown below:

\> ipconfig Windows IP configuration

Ethernet adapter [TIWLNAPI1]:

        IP Address ........ : 192.168.1.70
        Subnet Mask ....... : 255.255.255.0

Ethernet adapter [BTPAN1]:

        IP Address ........ : 0.0.0.0
        Subnet Mask ....... : 0.0.0.0

Ethernet adapter [SMSC91181]:

        IP Address ........ : 192.168.1.10
        Subnet Mask ....... : 255.255.255.0

4. Configure the IP address of the laptop that is connected to the access point via the Ethernet cable to be in the same subnet as the EVM WLAN port. In this example, it is configured to 192.168.1.100. The gateway IP address is not important for this test.

5. Use the Ping command to ping the PC that is connected to the access point. In the EVM menu, type the following:

\> ping 192.168.1.100

   Pinging Host 192.168.1.100
   Reply from 192.168.1.100: Echo size=32 time=95ms TTL=128
   Reply from 192.168.1.100: Echo size=32 time=48ms TTL=128
   Reply from 192.168.1.100: Echo size=32 time=67ms TTL=128
   Reply from 192.168.1.100: Echo size=32 time=64ms TTL=128
