Host ubuntu10.10. Compilation tool: Arm-Linux-GCC 4.3.3 embedded platform S3C2440 kernel Linux. 2.6.37.4.

 

Just got a Mercury wireless network card. My first reaction was to take a look. Rui rtl8188cuz chip. I can see that the CD files that come with the NIC are Linux drivers. A Word document in it helps me a lot. How to support new platform. Doc. It will teach you how to modify makefile. First copy the driver file to the host. Modify makefile. Config_platform_i1__pc = y
Config_platform_android_x86 = N
Config_platform_arm_s3c2k4 = N
Config_platform_arm_pxa2xx = N
Config_platform_arm_initi6k4 = N
Config_platform_mips_rmi = N
Config_platform_rtd2880b = N
Config_platform_mips_ar9132 = N
Config_platform_mt53xx = N
Config_platform_rtk_dmp = N
Config_platform_arm_tcc8900 = N
Config_platform_arm_mx51_241h = N
Config_platform_actions_atj227x = N
Config_platform_ti_dm365 = N
Config_platform_rk2818 = N
Config_platform_mips_jz4760 = n. The default value is i386 -- PC. Select your own platform. I only need arm_s3c2k4 = Y, i1__pc = n, and then modify the compilation tool. Kernel path.

Ifeq ($ (config_platform_arm_s3c2k4), Y)
Extra_cflags + =-dconfig_little_endian
Arch: = arm
Cross_compile: = arm-Linux-
Kver: = 2.6.37.4
Ksrc: =/home/lilei/linux-2.6.37.4
Endif

Cross -- complize corresponds to the compilation tool. Kver corresponds to the kernel version. Then, ksrc is the kernel path. This must be correct. Okay. The makefile has been changed. Isn't it easy. Make compilation after modification

 

What is the situation? First go to the Internet to receive it. Is there any such situation. No. By yourself. Find the corresponding C file. Comment out the init-mutex function. Compile in make. Hey. Success.

 

8192cu. Ko is the file we want. Copy to the Development Board. Insmod 8192cu. Ko, I am dumb. Error message. I think it is a driver problem. The init-mutesx function is not running. Let me check the official website of RealTek. I see the driver provided on the official website. The kernel 2.6.3... is supported. I can see that the driver on the official website is the 201104 month. The drive on my CD is the 201101 month. No matter. Try the driver on the official website, modify the makefile as above, and then make. Do not compile it successfully at once. Copy the generated 8192cu. Ko to the Development Board. Overwrite the original one. Remember to add permissions to this file.
