This is a fork from the whitebatman2/rtl8821CU library. Compilation error FIX on ARM devices -> "gcc: error: -mfloat-abi=soft and -mfloat-abi=hard may not be used together"
Tested in following environments.
Kernal 4.19.62-sunxi, Ubuntu 18.04.3 boinic.
Linux raspberrypi 4.19.97-v7+ armv7l GNU/Linux
Drivers for rtl8811CU and rtl8821CU Wi-Fi chipsets. This repository is based on soruce code found on a CD shipped with a rtl8811CU based card. It's updated to build on newer kernel versions.
DKMS is a system which will automatically recompile and install a kernel module when a new kernel gets installed or updated. To make use of DKMS, install the dkms package, which on Debian (based) systems is done like this:
apt-get install dkms
To make use of the DKMS feature with this project, do the following:
DRV_NAME=rtl8821CU
DRV_VERSION=5.2.5.3
sudo mkdir /usr/src/${DRV_NAME}-${DRV_VERSION}
git archive master | sudo tar -x -C /usr/src/${DRV_NAME}-${DRV_VERSION}
sudo dkms add -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms build -m ${DRV_NAME} -v ${DRV_VERSION}
sudo dkms install -m ${DRV_NAME} -v ${DRV_VERSION}
If you later on want to remove it again, do the following:
DRV_NAME=rtl8821CU
DRV_VERSION=5.2.5.3
sudo dkms remove ${DRV_NAME}/${DRV_VERSION} --all
First, makesure the kernel headers are installed
RaspberryPi -> sudo apt install raspberrypi-kernel-headers
Use following commands in source directory:
make
sudo make install
sudo modprobe 8821cu
If you successfully install the driver, the driver is installed on /lib/modules/<linux version>/kernel/drivers/net/wireless. Check the driver with the ls command:
ls /lib/modules/$(uname -r)/kernel/drivers/net/wireless
Make sure 8821cu.ko file present on that directory
