This tutorial based on this forum topic and modified by Giovanni Bruno Repo

NOTE: do everything as superuser (sudo su)

1. Kernel Updates (Only do Kernel updates while your Kernel system not 4.14.+) Kernel Building

sudo apt install git gcc g++ build-essential
git clone --depth 1 https://github.com/hardkernel/linux -b odroidxu4-4.14.y
cd linux
make odroidxu4_defconfig
make -j8
sudo make modules_install
sudo cp -f arch/arm/boot/zImage /media/boot
sudo cp -f arch/arm/boot/dts/exynos5422-odroidxu3.dtb /media/boot
sudo cp -f arch/arm/boot/dts/exynos5422-odroidxu4.dtb /media/boot
sudo cp -f arch/arm/boot/dts/exynos5422-odroidxu3-lite.dtb /media/boot
sudo sync
sudo reboot

2. Kernel Sources in /usr/src/

wget https://github.com/hardkernel/linux/archive/odroidxu4-4.14.y.zip
mv odroidxu4-4.14.y.zip /usr/src/linux.zip
cd /usr/src
7z x -y linux.zip
ln -s linux-odroidxu4-4.14.y linux

3. Check Kernel Version

NOTE: extraversion should be with minus e.g. 4.14.5-92 -> extraversion is -92

cd /usr/src/linux
uname -a

check Makefile version

head Makefile

add Makefile extraversion = -92

nano Makefile

4. Copy Required Configuration

ll arch/arm/configs
cp arch/arm/configs/odroidxu4_defconfig ./.config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers /usr/src/linux

5. Install Ncurses Library

apt-get install libncurses5-dev libssl-dev

6. Run Kernel Source Configuration

NOTE: just exit

make menuconfig
make prepare
make modules_prepare

7. Download Driver

Source from Github lwfinger

git clone https://github.com/ezracb/TL-WN725N_V2.git

8. Build

Odroid XU4 has limited resources of Memory so here is the way to compile the driver

cd rtl8188eu
make clean
CONFIG_RTL8188EU=m make -C /usr/src/linux M=`pwd`

9. Copy the build information into the kernel drivers

cp 8188eu.ko /lib/modules/$(uname -r)/kernel/drivers/net/wireless/
depmod -a
modprobe 8188eu

NOTE: if errors appear use dmesg

10. Test Wifi

lsmod
iwlist wlan0 scan

11. Configure

nmtui
check using
nmcli c
ifconfig -a
