How-to use USB to Wi-Fi adapters on your APF boards.
Contents
Prerequesities
Note: You have to be sure that Wireless Tools are installed on your rootfs before going further. |
- To use USB dongles with APF9328, you'll need an APF9328DevFull development board, with USB Host configured. See this page to know how to do that.

Ralink RT2571WF
The RT2571WF Wi-Fi chipset can be found in the following devices:
- D-Link DWL-G122 (not rev E1 !)
- D-Link WPA-110
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
- Tested with SMC WUSB-G (which is in the compatibility list).
- Go here to buy this device in France (LDLC)
- Other ways to get it ?
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
- http://zd1211.ath.cx/get-firmware
- copy the archive to your TFTP export directory
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
