ARM Development Board Load Realtek-8188cus USB wireless card (i)

Platform parameters: Kernel: Linux 3.6 file system: Busybox-1.20.2 hardware parameters: s3c2416

In the Arm-linux support and auto mount USB drive has been verified that the USB interface is completely normal, so do not worry about hardware failure.

First, the Primer

BZ uses a "Fast" USB interface wireless card, model fast FW150US, the story about this NIC 、、、

Real

The Linux LSUSB command allows you to view the Realtek 8188CUS chip that is used internally:

Second, the official opening

1, first download the corresponding driver source package on the Realtek official website:

By reading Document\quick_start_guide_for_driver_compilation_and_ Installation.pdf documentation We know that the driver source code in the driver directory, according to the hardware platform, modify the makefile:

A, platform selection:config_platform_i386_pc = n config_platform_arm_s3c2k4 = y

b, modify the compiled tool used, the corresponding kernel directory:

Ifeq ($ (config_platform_arm_s3c2k4), y) Extra_cflags + =-dconfig_little_endianarch: = armcross_compile: =/usr/local/ arm/4.2.2-eabi/usr/bin/arm-linux-# kver  : = 2.6.24.7_$ (ARCH) ksrc: =/home/uni/workspace/20141107_yisuo/linux_3_ 6/linux-3.6endif

C, PS: first the energy-saving function was canceled config_power_saving = n

Configure the above options and get the drive module after make:8192cu.ko

2. Module Loading:

Upload the file to the file system, in order to automatically load the module, add it to the Linux startup script:

/etc/init.d/rcs:insmod  /lib/modules/8192cu.ko

In this way, you can see the wireless network card recognition during system startup:
