OMAP Wireless Connectivity AM18x Operating the WLAN
Contents
Use of Terminal & GUI[edit]
For the current release in order to operate the WLAN, one have to use the serial port in order to rus a script that brings up the WLAN, and then additional script to get the DHCP runing. the rest of the WLAN control will be done using the GUI, that is Scaning for WiFi networks and connect to specific Access Point. that will be fixed in future release to have all the WLAN fanctions from GUI only.
the following step will guide through the basic WLAN bring up.
- Booting the EVM
- Verify Release vertion (Terminal command)
- Booting the WLAN (Terminal command)
- Scan for WiFi network and connect to Access Point (using GUI)
- Getting IP Adress using DHCP protocol (Terminal command)
- Web Bowsing (using GUI)
Boot Params[edit]
first stage is to connect the serial port to the PC and use TeraTerm (or any oter Utility) to control the EVM through a serial Terminal. after Power cycle hit a key when the message "Hit any key to stop autoboot" appears, and then press "printenv" to verify the Boot params. the main commands are:
- bootcmd - which in that case indicates that the uImage is boot up from the SD Card
- bootargs - which in that case indicates that the file system is in SD card in Sector 2, and the serial consule paramaters

then reboot the EVM and let it boot till the linux prompt, you will see the following on the screen:

verify the release version[edit]
then to verify the release version that is runing use "cat /proc/version" command
root@am180x-evm:~# cat /proc/version Linux version 2.6.33-rc4 (schuyler_2@neo) (gcc version 4.3.3 (Sourcery G++ Lite 2009q1-203) ) #1 PRE EMPT Wed Jan 12 00:43:46 CST 2011
Use Terminal to Bring up the WLAN[edit]
next step is to bring up the WLAN:
root@am180x-evm:~# root@am180x-evm:~# cd /usr/share/wl1271-demos/ root@am180x-evm:/usr/share/wl1271-demos# cd wlan/ root@am180x-evm:/usr/share/wl1271-demos/wlan# ./install-wlan.sh
Then note the WLAN booting stage on the screen

use the GUI for WLAN commands[edit]
now the EVM is ready to start working with the WLAN.
the WLAN control can be perform by the GUI, starting in the Wi-Fi button
connect to WiFi Access Point[edit]
in order to connect to WiFi Access point please refer to the the link: <AM18x connect to non secured network>
Get IP Address - DHCP[edit]
after connecting to Access point, please use the Terminal to get IP address by using DHCP protocol
