How-to use USB to Wi-Fi adapters on your APF boards.

Prerequesities

Note Note: You have to be sure that Wireless Tools are installed on your rootfs before going further.


Tested hardware

Ralink RT2571WF

The RT2571WF Wi-Fi chipset can be found in the following devices:

Drivers are included in Linux kernel > 2.6.29, but firmware must be downloaded from serialmonkey website at this address.

To use it with APF9328, you need an APF9328DevFull development board (with USB Host).

Kernel configuration

  • First, to use a USB dongle, USB Host must be configured. (Nothing to do on APF27, see this page to know how to do with the APF9328DevFull).
  • Then, Wireless network must be configured selecting these options in make linux-menuconfig:
 [*] Networking support  --->
    Wireless  --->
        <*> Generic IEEE 802.11 Networking Stack (mac80211)
  • Finally, select the chipset :
 Device Drivers  --->
    [*] Network device support  --->
        Wireless LAN  --->
            [*] Wireless LAN (IEEE 802.11)
            <M> Ralink driver support
            <M> Ralink rt2501/rt73 (USB) support

Wi-Fi configuration

First mount the module:

# modprobe rt73usb

Then copy the firmware named rt73.bin (found in Module directory of rt73-cvs archive) in apf /lib/firmware directory. If /lib/firmware doesn't exist create it.

 mkdir -p /lib/firmware
 tftp -g -r rt73.bin <yourIP>
 mv rt73.bin /lib/firmware

Your Wi-Fi module driver is ready, you can now connect the dongle and after go further with the Wi-Fi configuration.

ZyDas zd1212 chipset

Configure Linux

 $ make linux26-menuconfig
 [*] Networking support  --->
    Wireless  --->
        <*> Generic IEEE 802.11 Networking Stack (mac80211)

 Device Drivers  --->
     [*] Network device support  --->
         Wireless LAN  --->
             [*] Wireless LAN (IEEE 802.11)
             ...
             <M> ZyDAS ZD1211/ZD1211B USB-wireless support
             [*]   ZyDAS ZD1211 debugging
 $ make linux26 && make

Reinstall your system.

Get firmware

Install firmware on your APF

 # mkdir -p /lib/firmware/
 # cd /lib/firmware/
 # tftp -g -r zd1211-firmware-1.4.tar.bz2 192.168.0.17
 # bunzip2 zd1211-firmware-1.4.tar.bz2
 # tar xf zd1211-firmware-1.4.tar
 # mv zd1211-firmware zd1211

Connect your USB adapter
