Tp-Link TL-WN822N V5 [8/19] Compile the driver source

may take a few minutes.

$ make –j4 zImage modules dtbs

$ sudo make modules_install

$ sudo cp arch /arm/boot/dts/*.dtb /boot/

$ sudo cp arch/arm/boot/dts/overlays/*.dtb* /boot/overlays/

$ sudo cp arch/arm/boot/dts/overlays/README /boot/overlays/

$ sudo cp arch/arm/boot/zImage /boot/$KERNEL.img

Note: “-j4” refers to using Raspberry Pi3 and 4 to compile to accelerate the compilation

process.

Power off the development board of Raspberry Pi3 and then run the following command

to confirm the kernel version.

$ uname –a

$ cat /proc/version

2.2. Compile the Driver Source

Go to the driver’s directory, open the Makefile file to support Raspberry Pi3. By default, the

CONFIG_PLATFORM_I386_PC macro is enabled. Set the value for

CONFIG_PLATFORM_BCM2709 to y, and set the value for

CONFIG_PLATFORM_I386_PC to n.

CONFIG_PLATFORM_BCM2709 = y

CONFIG_PLATFORM_I386_PC = n

CONFIG_PLATFORM_ANDROID_X86 = n

After setting the parameters, use Terminal to go to the directory in which the driver source

file is stored. Run the following commands to compile the driver.

$ make clean

$ make

3. Load the Driver

Here we show the 8192eu.ko wireless driver loading process as an example. Run the

following command to load the driver.

$ sudo cp 8192eu.ko /lib/modules/[kernel version]/kernel/drivers/net/wireless/

$ sudo depmod -a

$ sudo modprobe 8192eu

Or directly use insmod to load the driver.

$ sudo insmod 8192eu.ko

After loading the driver, run the following command to check if the driver is successfully

loaded.
