WiFi Linux驱动移植v1.0.doc

Wi-Fi Linux驱动移植第一步:拷贝源码(2011_0407_5700_5800_Linux_android_V_DPO)到linux PC系统中请修改Makefile中的ARM平台请选择PLATFORM=SMDK再在SMDK项中修改ifeq ($(PLATFORM),SMDK)LINUX_SRC = 替换为源码目录路径 如：/root/lsl/linux-CROSS_COMPILE = 替换为交差编译器目录路径 如：arm-linux-Endif再make 一下先第二步:编译后，我们需要三个文件，它们要放在我们的下位机的目录下的。把驱动和相关文件拷到板子上相应目录下，注意这里对RT2870STA.dat要用dos2unix先转一下。#dos2unix RT2870STA/RT2870STA.dat把RT2870STA.dat拷贝到/etc/Wireless/RT2870STA目录下#chmod +x /etc/Wireless/RT2870STA/RT2870STA.dat把rt2870.bin usb固件拷贝到/lib/firmware此路径有严格要求#cp common/rt2870.bin /lib/firmware/把rt3070sta.ko拷贝到目标系统的/lib/modules目录下#cp rt3070sta.ko /lib/modules上面涉及的目录是没有的，需要自己建立.第三步:这个时候就可以使用加载了# insmod /lib/modules/rt3070sta.ko rtusb init rt2870 -= pAd = c48e3000, size = 508592 =- RTMPAllocTxRxRingMemory, Status=0RTUSBVenderReset Error!
