=== Ralink RT2571WF ===
+
−
The WiFi chipset RT2571WF can be found under '''the D-Link WiFi key
+
−
[http://www.ldlc.com/fiche/PB00023863.html DWL-G122]'''. All drivers are

−
included in Linux kernel 2.6.27. But firmware must be downloaded from
+
−
serialmonkey website at [http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz this address].
+
  
−
To use it with [[APF9328]], you need an [[APF9328DevFull]] development board (with USB Host).

==Prerequesities==
 +
{{Note| You have to be sure that [[Wireless Tools]] are installed on your rootfs before going further.}}

==== Kernel configuration ====
+
* To use USB dongles with [[APF9328]], you'll need an [[APF9328DevFull]] development board, with USB Host configured. See [[ISP1761_Linux_driver|this page]] to know how to do that.
  
−
* First, to use a USB dongle, USB Host must be configured. See [[ISP1761_Linux_driver|this page]] to know how to do with the [[APF9328DevFull]].
+
==Tested hardware==
−
* Then, Wireless network must be configured selecting these options in ''make linux-menuconfig'':

Thanks to Sly for this contribution.

 +
Here are the details for the RTL8188CUS driver for the APF28.
 +
 
 +
===Build procedure===
 +
Build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 .
 +
You can get the driver here (chose RTL8188CUS) :

 +
Add those option in the makefile :
 +
<pre class="host">

 +
CONFIG_PLATFORM_I386_PC = n
 +
- add line 40 :
 +

 +
 
 +
- Near line 261 add:
 +
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
 +

 +
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
 +
endif
 +
</pre>
 +
 
 +
finally copy the driver to the target directory :
 +
<pre class="host">
 +
cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/

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

TP-LINK TL-WN823N NT ~OK ? (3.7+ kernel) NT NT Realtek 8192CU

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.

Kernel configuration

  • If not already done, Wireless network must be configured by selecting these options in make linux-menuconfig:
 [*] Networking support  --->
    Wireless  --->
        <*> Generic IEEE 802.11 Networking Stack (mac80211)
  • then, 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.

Ralink RT2870

  • Activate the driver in Linux configuration (if not already done):
$ make linux-menuconfig
  • Load driver
# modprobe rt2800_usb
  • Be sure to have rt2870.bin in /lib/firmware

ZyDas zd1212 chipset

Configure Linux

 $ make linux-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 linux && 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

Chipset RTL8188CUS

Thanks to Sly for this contribution.

Here are the details for the RTL8188CUS driver for the APF28.

Build procedure

Build the driver for chip RTL8188CUS from source rtl8188C_8192C_usb_linux_v3.4.3_4369.20120622 . You can get the driver here (chose RTL8188CUS) : [1]

Add those option in the makefile : 

- change line 39 :
CONFIG_PLATFORM_I386_PC = n
- add line 40 :
CONFIG_PLATFORM_ARM_ARMADEUS = y

- Near line 261 add:
ifeq ($(CONFIG_PLATFORM_ARM_ARMADEUS), y)
EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN -DCONFIG_WEXT_PRIV
ARCH := arm
CROSS_COMPILE := /path-to-your/armadeus/buildroot/output/host/usr/bin/arm-linux-
KVER  := 2.6.35.3
KSRC ?= /path-to-your/armadeus/buildroot/output/build/linux-2.6.35.3
endif

finally copy the driver to the target directory : 

cp 8192cu.ko /path-to-your/armadeus/buildroot/output/target/lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/

Rebuild your armadeus roots and reprogram your board: 

cd /path-to-your-armadeus-directory
make
cp build root/output/images/* /tftpboot

Launch driver

# insmod /lib/modules/2.6.35.3\+/kernel/drivers/net/wireless/8192cu.ko
