Realtek 8192CU drivers for Linux

Configured to be cross compiled to PXA2XX platform with debug statements greatly reduced.

Tested with the Edimax EW-7811Un Amazon link or TP-LINK TL-WN823N Amazon link. The driver should load automatically when the USB wifi device is inserted.

Compile

Export appropriate variables:

export ARCH=arm
export KVER=2.6.32.27
export KSRC=/mnt/src/device-os/kernel/cm-x300/build/linux-2.6.32.27

Run make.

The result is the kernel module file is 8192cu.ko, which is what will be installed on the device.

Installing

MODULE_FILE=8192cu.ko
MODULE_DIR=/lib/modules/$(uname -r)/kernel/drivers/net/wireless
cp -v $MODULE_FILE $MODULE_DIR
depmod -a

To test that the module loads properly:

modprobe -v 8192cu

To verify the module is loaded:

lsmod | grep 8192cu

If the module is listed, you are good to go. To unload the module (it will load automatically when necessary):

rmmod -v 8192cu

Misc.

To create md5 checksum file:

md5sum 8192cu.ko > 8192cu.ko.md5

To verify md5 checksum:

md5sum --check 8192cu.ko.md5
