整理一下Wi-Fi的启动流程： 1.系统启动通过sunxi-rf驱动读取board.dts配置，解析供电，sdio，引脚，时钟等配置。完成上电动作。 2.驱动加载时完成扫卡，下载firmware，add wlan0 interface。 3.系统的自启动脚本在etc/init.d/wpa_supplicant中启动服务，启wlan0。 4.利用wpa_cli/wifimanager进行应用的操作。
建议排查思路： 1.系统起来执行lsmod 查看xradio_mac/xradio_core/xradio_wlan(也有可能是单ko的形式xr829)驱动是否加载成功。 顺便提一下驱动加载失败最常见的错误：
代码语言：javascript复制1.供电不匹配。
2.扫卡时失败，sdio配置错误。
3.下载firmware失败。（注意路径：默认是/lib/firmware）2.执行ps | grep wpa_supplicant查看服务是否启动。 也可以直接执行
代码语言：javascript复制./etc/init.d/wpa_supplicant start //再次手动启动服务启动失败的常见原因：
代码语言：javascript复制1.前面驱动加载已经失败了，导致没有wlan0 interface.
2.配置文件不存在比如:wpa_supplicant.conf。默认是在/etc/wifi、目录下
3.文件存在，但是文件系统只读，导致无法对配置文件写操作。可以手动执行wpa_supplicant命令起服务就可以看到提示如下：
代码语言：javascript复制Successfully initialized wpa_supplicant
[ 796.252780] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready
mkdir[ctrl_interface=/etc/wifi/sockets]: **Read-only file system**
Failed to initialize control interface '/etc/wifi/sockets'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.
nl80211: deinit ifname=wlan0 disabled_11b_rates=0解决办法： 1.直接修改文件系统，换成可读写的，例如ext4. 2.可以自己临时创建配置文件到/tmp目录。
