[edit] Beagle Board mac80211 Connectivity

[edit] Summary

Provided you have the Beagle Board and the associated WLAN daughter card it is quite easy to get the WiLink up and running on it. This page provides you the relevant information to do that. (The OpenLink.org site provides information on the open source software development effort for it.)

For background information on the Beagle Board visit:

• BeagleBoard Wiki

To get WiLink on the Beagle Board you have to have the WLAN daughter card for it. This expansion card enables the wireless connectivity functionality:

• BeagleToy WLAN adapter at boardzoo.com

[edit] Hardware information

To obtain a Beagle Board you can visit the vendor sites linked on this page:

• BeagleBoard Hardware

The following page has the vendor information for the new BeagleBoard-xM (see Buy-xM page):

• About BeagleBoard-xM

[edit] Board Setup

First steps:

• Pre-requisite: minicom (or another terminal app)
• Insert the micro-SD card
• Connect the USB-serial adapter
• Connect the USB cable (power supply)

Start minicom:

• Use: minicom -s -o
• Use: /dev/ttyUSB0
• Set: 115200 8N1
• Set: No HW/SW flow control

Log in to the serial console.

Beagle Board uses a two-phase boot:

• First phase: X-Loader (MLO)
• Second phase: u-boot.bin

1. Sets up the environment
2. Kernel parameters given to this for booting of kernel.

[edit] Software:

Which (Linux) Kernel should I use?:

• Mainline-based Linux: 2.6.39-rc1
• One patch for the WLAN daughter card: File:0001-omap-beagle-add-support-for-wl1271-on-the-board-file.patch.gz

[edit] Connecting to an open Access Point

Once you have the Beagle Board (with the WLAN daughter card) up and running a variant of Linux (with the WLAN patches applied) you are almost home. The following steps show you how to get the interface up.

Set your own MAC address:

 ifconfig wlan0 hw ether 08:00:28:00:00:<number>
 ifconfig wlan0 up

Using the iw tool to scan:

 iw wlan0 scan

Connecting to an open AP:

 iw wlan0 connect -w OpenLink
 dhclient wlan0
 ping 192.168.1.1

Disconnect:

 iw wlan0 disconnect

[edit] Connecting to a WEP AP

Connecting with iw using a pre-defined key:

   iw wlan0 connect -w OpenLinkWEP key 0:00deadbeef

Connecting with wpa_supplicant:

  vim wep.conf
 
   ctrl_interface=DIR=/var/run/wpa_supplicant
 
   network={
           ssid="OpenLinkWEP"
           scan_ssid=1
           key_mgmt=NONE
           wep_key0=00deadbeef
   }

 wpa_supplicant -B -i wlan0 -c wep.conf 
 wpa_cli status
 dhclient wlan0
 ping 192.168.1.1

[edit] Downloads:

Patch to get WLAN working (for Linux kernels):

• One patch for the WLAN daughter card: File:0001-omap-beagle-add-support-for-wl1271-on-the-board-file.patch.gz
