icelaglace/MiSTer_WiFi_EW-7811UNv2

Enables Wi-Fi for the Edimax EW-7811UN v2 on the MiSTer

You now don't need this driver for the MiSTer FPGA! It has been included inside the Linux Kernel since 5.14.

Thanks to Alexey for this!

Installation

• Download the .ko file in the Releases folder : LINK
• Connect to the MiSTer via SSH/FTP using either Serial Console or Ethernet or simply plug the SD Card in your computer.
• Transfer the .ko file to /lib/modules/(YOUR KERNEL VERSION)/
• Use a keyboard and press F9 or connect to SSH and type :

depmod -a
modprobe 8188eu
reboot

Compilation (Step by step)

On Debian / Ubuntu, I used WSL Ubuntu on my end :

• Install ARM cross-compile toolchain & build essentials : apt-get install gcc-arm-linux-gnueabihf build-essential
• Install Bison : apt-get install bison
• Install Flex : apt-get install flex
• Install OpenSSL-dev apt-get install libssl-dev
• Create a folder called build by typing mkdir build
• Go to the folder : cd build
• Clone the Linux MiSTer Kernel : git clone https://github.com/MiSTer-devel/Linux-Kernel_MiSTer
• Clone this repo : git clone https://github.com/icelaglace/MiSTer_WiFi_EW-7811UNv2
• Delete .git folder inside the Linux-Kernel_MiSTer & MiSTer_WiFi_EW-7811UNv2 folders (Recommended by Sigurd Bøe)
• Go to the Linux MiSTer Kernel folder and type :

make ARCH=arm mrproper && make ARCH=arm MiSTer_defconfig && make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- EXTRAVERSION=-MiSTer modules_prepare

• Once it's done, go to MiSTer_WiFi_EW-7811UNv2 folder and type :

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- clean && make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- KSRC=../Linux-Kernel_MiSTer modules

KSRC is the path of the Linux kernel you just compiled, change accordingly if you didn't follow the exact instructions

Compilation (copy and paste) for Debian-based distributions

apt-get install gcc-arm-linux-gnueabihf build-essential
apt-get install bison
apt-get install flex
apt-get install libssl-dev
mkdir build && cd build
git clone https://github.com/MiSTer-devel/Linux-Kernel_MiSTer
git clone https://github.com/icelaglace/MiSTer_WiFi_EW-7811UNv2
cd Linux-Kernel_MiSTer
rm -rf .git
make ARCH=arm mrproper && make ARCH=arm MiSTer_defconfig && make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- EXTRAVERSION=-MiSTer modules_prepare
cd ../MiSTer_WiFi_EW-7811UNv2
rm -rf .git
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- clean && make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- KSRC=../Linux-Kernel_MiSTer modules

Troubleshoot

• If you don't have the .bin /lib/firmware/rtlwifi called rtl8188eufw.bin,go to https://github.com/wkennington/linux-firmware and download : rtlwifi/rtl8188eufw.bin
• Transfer the .bin file to /lib/firmware/rtlwifi

Thanks to this guide for the instructions :)
