0 主机平台： UBUNTU14.04 硬件平台：明远智睿MY-IMX6-EK200 编译器: gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux.tar.xz buildroot版本：buildroot-2017.02.5.tar.bz2 内核版本 linux-3.14.52 1.内核需要配置,配置完直接编译zImage CONFIG_CFG80211=y CONFIG_MAC80211=y CONFIG_HOSTAP=y CONFIG_USB_USBNET=y 2. 编译rtl8188eus模块源码包：rtl8188EUS_linux_v4.3.0.9_15178.20150907%28myimx6%29.tar.xz $ tar xvf rtl8188EUS_linux_v4.3.0.9_15178.20150907%28myimx6%29.tar.xz $ cd rtl8188EUS_linux_v4.3.0.9_15178.20150907 $ vim Makefile 修改增加（源码路径和交叉编译工具路径） ifeq ($(CONFIG_PLATFORM_ARM_MYIMX6), y) EXTRA_CFLAGS += -DCONFIG_LITTLE_ENDIAN ARCH := arm CROSS_COMPILE ?= ~/IMX6/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf- KVER ?= 3.14.52 KSRC ?= /home/linyn/rs485/linux-custom endif vim include/autoconf.h 修改： #define CONFIG_IOCTL_CFG80211 #ifdef CONFIG_IOCTL_CFG80211 #define RTW_USE_CFG80211_STA_EVENT //#defineCONFIG_CFG80211_FORCE_COMPAtiBLE_2_6_37_UNDER //#define CONFIG_DEBUG_CFG80211 1 #endif ... ... #define CONFIG_CONCURRENT_MODE … 最后编译模块8188eu.ko 3.移植hostapd和dhcpd a)如果是用buildroot编译的话，直接用make menuconfig配置就行,这里不讲了 b)或者自己独立编译hostapd和dhcpd 4.配置hostapd和dhcpd a) 配置hostapd vim /etc/hostapd.conf interface=wlan0 driver=nl80211 ssid=MYZR channel=9 hw_mode=g macaddr_acl=0 ignore_broadcast_ssid=0 auth_algs=1 wpa=3 wpa_passphrase=12345678 wpa_key_mgmt=WPA-PSK wpa_pairwise=TKIP rsn_pairwise=CCMP b)配置dhcpd touch /var/db/dhcpd.leases vim /etc/dhcpd.conf 在最后增加： subnet 192.168.155.0 netmask 255.255.255.0 { range 192.168.155.2 192.168.155.10; option domain-name-servers 8.8.8.8; option routers 192.168.155.1; } 5.启动热点和自动获取IP echo "1" >/proc/sys/net/ipv4/ip_forward hostapd -B /etc/hostapd.conf ifconfig wlan0 192.168.155.1 dhcpd wlan0 看图片“WIFIAP.png” 最后通过手机，可以搜索“MYZR”的热点，直接输入密码“12345678”，这样手机WIF连接成功，会自动分别192.168.155.的IP. 注意：以上虽然分配到IP，但是不能上网，需要使用iptables开启本地的SNAT 经过前面几个步骤，无线网卡已经可以自动分配IP，现在只需要把无线网卡的数据都经过eth0(有线网络)发到外网去，这就需要IP转发了。 6.配置内核 Networking support ---> Networking options --->Network packet filtering framework (Netfilter) ---> Core Netfilter Configuration ---> //除了下面列出的其他全选 < > Transparent proxying support (EXPERIMENTAL) < > set target and match support < > CHECKSUM target support < > "CT" target support < > "DSCP" and "TOS" target support < > "NOTRACK" target support < > "TCPOPTSTRIP" target support (EXPERIMENTAL) < > "dscp" and "tos" match support < > "ipvs" match support <> IP set support ---> (256) Maximum number of IP sets <> bitmap:ip set support <> bitmap:ip,mac set support <> bitmap:port set support <> list:set set support <> IP virtual server support ---> //除了下面列出的其他全选 [ ] IP virtual server debugging [ ] SCTP load balancing support < > FTP protocol helper < > SIP persistence engine IP: Netfilter Configuration ---> //里面的全选 <> RF switch subsystem support ---> //注意要选最后一项，不然在使用hostapd命令时会出错，“rfkill: Cannot open RFKILL control device”. 7.移植iptables直接用buildroot配置编译就行，或者独立编译，這里不讲了udhcpc -i eth0 iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE 这样连接wifi，手机和ubuntu的WPA2-PSK的无线wifi AP设置完毕，可以正常使用了。 0
