Driver specific information


Device Type sdio id sunxi-3.4 kernel mainline kernel
XR819 SDIO 0020:2281 xradio_wlan

For XR819 BSP driver can found here and firmware blobs can be found there or here. A more recent driver variant can be found at patch-add-support-xr819.tar.gz.

Also some documentation is available now: File:XR819 Datasheet V1.0-EN.pdf and File:XR819 Application Guide V1.0-CH.pdf

May be related to ST cw1XX0 [1].

Initial comparison between cw1200 (drivers/net/wireless/st/cw1200) and xradio driver shows that the source code for two drivers are really similar and the st1200 driver can be improved to support both devices.

A working out-of-tree driver for mainline kernels is at [2].


Ampak combines broadcom wifi and bluetooth chips in single modules.

Firstly, you should use Hans de Goede's sunxi-wip kernel branch containing various bits and pieces needed to make things work.

Driver itself is currently in its own repository:

git clone https://github.com/jwrdegoede/esp8089.git
git checkout -B cleanup origin/cleanup
cd ../linux
make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnu- modules M=../esp8089 CONFIG_ESP8089=m

Do not forget to copy firmware/*.bin to /lib/firmware/ on the target system.

RDA Microelectronics is a relatively unknown and new chinese chipmaker.

RDA5991 SDIO 5449:0145

The RDA5990P is a single chip solution which includes Wifi, Bluetooth and an FM radio. Some code for this wifi chip is available in a Rockchip RK3188 kernel tree, but nobody has tested or ported this code yet.

Datasheets: RDA5990P RDA5990


Most of the USB-based Realtek 8xxx are supported by the rtl8xxxu which is using the MAC80211 framework. Please always try this driver first, because it seems to be a lot more stable than "official" driver.

Legacy sunxi-3.4 kernel support

Driver refusing to load

When using the rt5370sta, 8188eu, 8189es or 8192cu drivers, which are all for USB based realtek devices, it might occur that the driver refuses to load:

ERR: script_parser_fetch usb_wifi_usbc_num failed
modprobe: can't load module 8188eu (kernel/drivers/net/wireless/rtl8188eu/8188eu.ko): Cannot allocate memory 

This is because the usb_wifi_para section is missing from your script.bin:

usb_wifi_used = 1
usb_wifi_usbc_num = 2

Where usb_wifi_usbc_num is the usbc to which your realtek usb wireless chip is attached.

Edit the .fex file and create the script .bin as explained in our Manual build howto, and send a patch to sunxi-boards in to our mailinglist.

8188eu driver on sunxi-3.4

The sunxi-3.4 branch currently has v4.1.2_4787.20120803 available. There are newer versions available at https://github.com/lwfinger/rtl8188eu/ which are v4.1.4_6773.20130222 and v4.1.8_9499.20131104. There's also a v4.1.8 file available at https://github.com/LazyZhu/myblog/raw/gh-pages/file/RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip which is likely the original from Realtek.

Here's how to compile the latest version from Realtek:

Extract the driver/rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104.tar.gz from the RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip file and extract it. These instructions assume your linux-sunxi directory is in the same directory as your rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104 directory. It's also assumed that you've configured the kernel to include the 8188eu driver that's part of linux-sunxi.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -C ../linux-sunxi/ M=`pwd` modules

copy the 8188eu.ko file over to the device and then install it into your kernel with the following commands (on the device as root):

modprobe -r 8188eu
rm -rf /lib/modules/`uname -r`/kernel/drivers/net/wireless/rtl8188eu
install -p -m 644 8188eu.ko /lib/modules/`uname -r`/kernel/drivers/net/wireless/
modprobe 8188eu

There are two changes you may want to make in include/autoconf.h:

1. The default is to output a LOT of logging and you can disable that by commenting out the following line:

#define CONFIG_DEBUG /* DBG_871X, etc... */

2. The default is to disable the activity LED on the wifi device which you may want to see to know that it's working. You can change that by un-commenting the following line:

//#define CONFIG_LED

Software Configuration

Debian/ubuntu with NetworkManager

NetworkManager uses its own wpa_supplicant configuration. That is the reason why manually editing /etc/network/interfaces to use wpa_supplicant does not work together with NetworkManager.

You have to disable all interfaces in /etc/network/interfaces e.g. by commenting out each line by inserting "#" as a first character.

You even have to disable Ethernet section to use wifi in network manager. Here is an example

   # interfaces(5) file used by ifup(8) and ifdown(8)
   auto lo
   iface lo inet loopback
   #allow-hotplug eth0
   #iface eth0 inet dhcp
   #auto eth0
   #iface eth0 inet static
   #auto wlan0
   #iface wlan0 inet dhcp
   #    wpa-ssid YOUR-NETWORK-NAME
   #    wpa-key-mgmt WPA-PSK
   #    wpa-group TKIP CCMP
   #    wpa-psk YOUR-NETWORK-KEY

At your desktop there should emerge a network icon from NetworkManager in the task bar. You can edit the network setting with the gui dialogs.

Debian/ubuntu without NetworkManager

Setup with wpa_supplicant and without network manager

There are many tutorials out there on how to do this. Here is a good one.

Disabling networkmanager. Fully.

Even with the common trick of putting the following in /etc/NetworkManager/NetworkManager.conf


the despotic NetworkManager still will be messing up your careful setup from /etc/network/interfaces, and you might, once again, be left without wifi upon the next reboot.

To stop NetworkManager from running altogether, you can run the following (as root):

echo "manual" > /etc/init/network-manager.override

Now, at least on ubuntu, your wifi driver, wpa_supplicant and ifupdown will not be smacked about anymore.

Simple and dumb WPA setup

Install the following packages, if they are not installed already:

apt-get install wireless-tools wpasupplicant

Edit /etc/network/interfaces and add the following:

auto wlan0
iface wlan0 inet dhcp
    wpa-ssid YourSSID
    wpa-psk YourWPASharedKey

This is the most basic, but static, setup possible for wifi. If you need anything more, you need to read up on wpa_supplicant, or run through one of the tutorials referenced above.


The following devices all come with an built-in wifi chip.
