hi3519v101平台搭建hostapd
作者：互联网
以前是有建立过在Ubuntu下面建立hostapd,现在海思项目有这么个需求,需要移植.
1.wifi驱动移植,看上章.
2.我们需要工具:hostapd热点;udhcpd动态分配ip;wpa_supplicant配置sta,可以连接wifi.
但是hostapd,wap_supplicant依赖于ssl和nl库.我所用的库openssl-1.0.2s , libnl-3.4.0, hostapd-2.8, udhcp-0.9.8 ,wpa_supplicant-2.8都是在他们官网上下载的.
下面是Makefile:

libopenssl_clean:
pushd $(DY_OPENSSL_SOURCE_DIR);make clean;popd
rm -rf $(DY_SUB_OPENSSL_INSTALL_DIR)
####编译nl3.4库
libnl3_4:

rm -rf $(DY_SUB_LIBNL_INSTALL_DIR)
########下面3个目录,Makefile需要修改:hostapd和wpa_supplicant修改:CC=arm-hisiv200-linux-gcc ; udhcpd修改:CROSS_COMPILE=arm-hisiv200-linux-
#######对于编译hostapd和wpa_supplicant, 需要对他们目录下的.config文件添加头文件和库路径:ssl和nl的库

#无线网卡选用1信道，一般为11.如2.4G(2.40-2.48)有14个信道(一个channel=22mhz),channel之间也是有重叠处，1-6-11不重叠。5g又有：34,36,38...64,100,104,108...140,149,153,157,161.
#channel与hw_mode有密切的关系。如果channel与hw_mode不一致会导致AP启动失败。mode=1 chan=1-11(2.4g)，mode=2 chan=36-165（5g）。如果用2.4gchannel对应的hw_mode=g,5gchannel对应的hw_mode=a. 802.11协议指定了802.11a对应5g，802.11g对应2g，其中802.11b也是2g，802.11n都支持。参考文档：http://wenku.baidu.com/link?url=K-I08AFxnJa0V3Y_2bW6EyvktIbkBUUfxpW6ZsjGdtD6Oxtw7kRR6x-nu2SaDeYRTJT_WdeexaTP270LiWYbSyG92u13w5t_F4bZmSPQPri
