Compile driver
$ make CC=/usr/local/arm/arm-2010q1/bin/arm-none-linux-gnueabi-gcc
CC is the cross-compiler used for compiling. After that, the created three executable files wpa_cli,
wpa_passphrase and wpa_supplicant are needed wpa tools. In this user manual, only used wpa_cli and

4.5 Configure WLAN through WAP Tool
Insert the MY-WF003U USB WiFi Module and then use WAP to configure wlan. How to use wap tool
and steps to configure wlan is as follow.
4.5.1 Using configuration file
Use wpa_passphase to generate configuration files,How to use wpa_passphase:
# wpa_passphase ssid ssid_code > /etc/wpa_supplicant.conf
If my WIFI SSID is my_wifi, password is: 12345678.
# wpa_passphase my_wifi 12345678 > /etc/wpa_supplicant.conf
“wpa_supplicant.conf” will be generated in directory /etc/, use this configuration to connect to wifi:
# wpa_supplicant -i wlan0 -c/etc/wpa_supplicant.conf -Dwext -B
After connecting wifi, use following command to obtain IP address:
# udhcpc -i wlan0
