Code: Select all

# go to kernel source directory
cd /home/pi/src/linux  - you will need to use the directory you store your source in.

My /home/pi dir exists, but I do not appear to have /src/linux inside here (searched for hidden types too)
I have run find / -type d "src" and cannot locate this folder.

I setup my Pi from http://downloads.raspberrypi.org/raspbian_latest image, image to microSD, and thats pretty much it.
Am I supposed to do some other step to get this /src/linux folder?

Hi PiHead,

The src directory is a directory I configured to put the source data for the kernel and driver code I use.

As an example I will show you how I compile the driver module, including downloading and configuring all the necessary code.

First I am starting with a newly set up SD card with raspbian 3.12.28+ from the Raspberry Pi Download page and it is connected to the internet using a wired network cable connection.

The command uname -a shows the following:-

Code: Select all

Linux raspberrypi 3.12.28+ #709 PREEMPT Mon Sep 8 15:28:00 BST 2014 armv6l GNU/Linux

After logging in which puts me in my home directory /home/pi I generate the src directory with the command

Code: Select all

mkdir src

Now I enter the source directory and download the source code for the kernel, the kernel firmware and the rtl8188eu driver. The command

Code: Select all

cd src

will put me in directory /home/pi/src.

Now download the linux kernel source, the kernel firmware and the driver source from the various git repositories with the commands

Code: Select all

git clone --depth 100 https://github.com/raspberrypi/linux.git
git clone --depth 25 https://github.com/raspberrypi/firmware.git
git clone https://github.com/lwfinger/rtl8188eu

Note: the option --depth xxx in the git clone commands above limits the amount of code downloaded otherwise it will literally take all day to download and most of the code will not be needed.

Now you will have three directories in the /home/pi/src directory. These are linux, firmware and rtl8188eu. Now we need to configure the linux and firmware directories to point to the right kernel version, 3.12.28+ #709, ready for compiling the driver. First enter the firmware directory and set it up with the commands

Code: Select all

cd firmware
git checkout 53d1ae311226b5cd7ea1277832139b74b2bb0f90

Be patient as the checkout may take some time before it appears to do anything. Now enter the linux source directory and set that up using commands

Code: Select all

cd ../linux
git checkout 94a382fed1a5ec303eef9e1f3439df8f759ba60c

The long numbers in the git checkout commands are the commit IDs and can be found looking at the firmware git repository for a particular kernel revision. For a particular kernel version look at the description of the commit to find the firmware commit ID and then browse the code and look at the value at extra/git_hash and that is the kernel commit ID for the particular kernel version.

Now we can configure the kernel ready to compile the driver. First initialise the kernel code and set up the .config file

Code: Select all

make mrproper
make bcmrpi_defconfig

The make bcmrpi_defconfig command is a general command using data included in the source code that can be used to generate the .config file even if you are compiling a kernel version that is different to the version currently running on the Pi. An alternative to this command if you are compiling for the kernel you are running on the Pi is zcat /proc/config.gz > .config and this will copy the .config used by the running kernel.

Now finish configuring the kernel ready to compile the driver with the following commands.

Code: Select all

make modules_prepare
cp ../firmware/extra/Module.symvers .

Note the period/full stop at the end of the cp command. The kernel should now be ready for compiling the wifi driver.

One final thing before compiling the driver. You will need to set up a pair of symbolic links that the driver compile requires to reference the kernel source directory when the driver is compiled. Set up the symlinks with the commands

Code: Select all

sudo ln -s /home/pi/src/linux /lib/modules/$(uname -r)/build
sudo ln -s /home/pi/src/linux/arch/arm /home/pi/src/linux/arch/armv6l

Now enter the wifi driver source directory and compile it with the following commands

Code: Select all

cd ../rtl8188eu
make clean
make
sudo make install

You should now have a driver compiled and installed. Now to get the wifi working you will have to configure the wifi either by editing the file /etc/network/interfaces and then rebooting or running the GUI and using the Wifi Config button.

As an alternative to using the lwfinger driver which requires a seperate firmware file you can use the driver I use. You can load both sets of source code as they use different directory names, rtl8188eu for lwfinger's version and rtl8188eus for the version I prefer. Load, compile and install the driver I use using the following commands. First enter the source directory and download the driver using one of the following sets of two commands

Code: Select all

cd /home/pi/src
wget http://lazyzhu.com/file/RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip

or

Code: Select all

cd /home/pi/src
wget https://dl.dropboxusercontent.com/u/80256631/RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip

Now unzip it and install the driver source.

Code: Select all

unzip -q RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip
cp RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104/driver/rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104.tar.gz .
tar xzf rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104.tar.gz
rm rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104.tar.gz
rm -r RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104
mv rtl8188EUS_rtl8189ES_linux_v4.1.8_9499.20131104 rtl8188eus

Note the period/full stop at the end of the cp command. The driver source is now in directory /home/pi/src/rtl8188eus. The driver now needs a patch applying to make it work with the Pi. Download the patch, go to the driver source directory and apply the patch.

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/rtl8188eus.patch
cd rtl8188eus
patch -p1 < ../rtl8188eus.patch

and now compile and install the driver

Code: Select all

make clean
make
sudo make install

and don't forget to update /etc/network/interfaces if necessary. And you can, if you want, install the source for both drivers and try compiling both drivers and see how each behave although only one or the other will be installed at any one time.

Once installed the driver file is at /lib/modules/3.12.28+/kernel/drivers/net/wireless/8188eu.ko. The lwfinger version also includes a separate firmware file which is installed at /lib/firmware/rtlwifi/rtl8188eufw.bin

Hopefully this is some help. There is also a lot on the internet about compiling modules for the Raspberry Pi which may be useful searching for and looking at.

Hi everyone,

The driver list has been updated to include the latest 3.12.35+ #730 raspbian version - http://www.raspberrypi.org/forums/viewt ... 82#p462982

[nrg-fv]

Can this driver be somehow included in raspbian kernel/repository?

[marudhanayagam]

today i went to shope for buying the subject wifi adpter and found ver2.1 only. now is version 2.1 compatible for adhoc mode?? i would like to stream videos from DLNA certified mobiles to tv thru Rpi, please tell me which wifi adapter is suitable ?? (of course we need to install certain packages in Rpi to meet the above requirements)

[kubunto]

I have taken down the latest driver and while I did not have any of the invalid module messages as others have mentioned, I was still unable to get the wireless adapter to work.

uname -r gives 3.12.35+ #700 (it matched the last one given in the original post)

The output you give for uname -r does not match what is in the OP. Do you mean 3.12.35+ #730?

With your wifi adaptor connected to your Pi what is the output from commands

Code: Select all

uname -a
lsusb
ifconfig

.
How did you try and configure your wifi? Manually editing file /etc/network/interfaces, or file /etc/wpa_supplicant/wpa_supplicant.conf or using the Wifi Config GUI?

[Ecofritze]

Thank you so much for this post!
I've read before that it could very difficult to get a wifi-dongle running on the pi when it doesn't work out of the box. But with your manual it was as easy as pi(e)!

RaspBerry Pi B+ with Sitecom N150 Wi-Fi-Dongle

susessfully wlan-connection with Sitecom N150 USB(2.0) Stick (update 8188eu driver)

--- excecute in a terminal window

1. get the kernel typ
$ uname -a --> Linux raspberrypi 3.12.35+ #730 PREEMT

2. get dongle id
$ lsusb --> Bus 001 Device 005: 0df6:0076 Sitecom Europe B.V.

3. find driver package on
http://www.raspberrypi.org/forums/viewt ... 82#p462982

4. download driver from https://dl.dropboxusercontent.com/u/802 ... 107.tar.gz

Instructions:
The driver installation instructions expect you to be using Raspbian, either installed from a basic rasbian image or installed using NOOBS. The instructions are based on running from a Command Line Terminal, not a GUI (Graphical User Interface). If you are running using the GUI you will need to open a terminal window and run the commands from the terminal window but I can't guarantee they will work.

uname -a --> RaspBerryPi 3.12.35+ #730

5. If you have a wired internet connection install the driver with the following commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20141107.tar.gz

Hi kubunto,

As the wifi module, wlan0, is not shown by command ifconfig then it appears that the driver is not installed, or not installed correctly, although I suppose it is possible the wifi module could possibly be faulty.

Using command lsmod do you see the wifi module, 8188eu, listed?

Do you see anything using command dmesg | grep -i "8188eu" ?

If the driver is loaded you should see something like

Code: Select all

[    6.774394] usbcore: registered new interface driver rtl8188eu

If you have the wrong driver version installed you would possibly see something like

Code: Select all

[    5.849112] 8188eu: disagrees about version of symbol wireless_send_event
[    5.980060] 8188eu: Unknown symbol wireless_send_event (err -22)

or other similar messages or possibly no message at all referencing 8188eu.

Try reinstalling the driver using commands

Code: Select all

wget https://dl.dropboxusercontent.com/u/80256631/8188eu-20141107.tar.gz
tar -zxvf 8188eu-20141107.tar.gz

I performed all RasPi updates today (e.g. rpi-update, apt-get update, etc.) and my uname result was 3.12.36 #737.

I don't see any recommendations in this thread for a file for #737, so I tried #730 version (8188eu-20141107.tar.gz), which did not work. I received an "invalid parameters" error when attempting the insmod command.

Any suggestions?

Thanks.

Boot into console, become root, go to /lib/firmware/rtlwifi and type

Sorry this is all too complicated!
I'm very new to all this!

I've just loaded the latest software. My new B+ has booted. All is good.

I now want WiFi. I have just been out and bought a TP-LINK nano USB adapter model TL-WN725N. The chap that sold it to me in MAPLINS said it was compatible with the Raspberry Pi.

I plug it in and nothing.

So I go to config. Nothing seen.

List lsusb

and it is shown as there id 0bda:8179

Now what?

Where is the driver? How do I find the driver? Where should I load it on the micro SD card? How do I load it on the micro SD card? (simple instructions using a mac would be helpful)

I thought this was supposed to be simple. (

Simple instructions please for a numpty novice

Go back to Maplins. Tell them it's not compatible. Get your money back.

Then buy this: https://www.modmypi.com/wireless-usb-1n ... ifi-dongle
or this: https://www.modmypi.com/tenda-wireless- ... rk-adapter

[jayemm96]

Hi,
Any idea when the driver for 3.18.3+ is coming out? I accidentally ran rpi-update before checking for drivers, and the old drivers for 3.12 dont work with 3.18.
Thanks

[MrEngman]

Hi guys,

If you update to 3.18.xx+ there is a version of the driver included in the image so you don't need to download a new driver, however, it needs a separate firmware file downloading and installing.

You can download and install the driver firmware file with the single command

Code: Select all

sudo wget https://github.com/lwfinger/rtl8188eu/raw/c83976d1dfb4793893158461430261562b3a5bf0/rtl8188eufw.bin -O /lib/firmware/rtlwifi/rtl8188eufw.bin

You will only need to do this once as it does not need updating when the linux version is updated. Also you will not need to load a new driver whenever you update the linux version as the new driver is now included in the code.

Once you have downloaded the firmware file reboot the Pi to bring up the wifi.

After rebooting, wpa_gui still did not list wlan0. But I removed and re-inserted the dongle from the USB hub and that got it working.

So really - no more of this song and dance for every OS update from now on? That is GREAT news! I was seriously just about to buy a different brand because I was tired of going through this every time.
