报错一：在配置AP模式的时候，出现挂载不上bcmdhd.ko的情况，并且是有规律的一次可以，一次不可以
hostapd的执行脚本如下：
1 #!/bin/sh 2 3 dir=`dirname $0` 4 cd $dir 5 modprobe ahci.ko 6 modprobe bcmdhd.ko 7 sleep 3 8 9 ifconfig wlan0 up 10 ifconfig wlan0 192.168.1.2 11 udhcpd /etc/udhcpd.conf 12 hostapd /etc/hostapd_5G.conf -B 13 sleep 3 14 #udhcpc -i wlan0&
即：modprobe bcmhdh.ko
报错：
解决：
将ifconfig配置移到hostapd配置之后执行
如下：
#!/bin/sh dir=`dirname $0` cd $dir modprobe ahci.ko modprobe bcmdhd.ko #sleep 3 #ifconfig wlan0 up #ifconfig wlan0 192.168.1.2 hostapd /etc/hostapd_5G.conf -B #sleep 3 ifconfig wlan0 192.168.1.2 udhcpd /etc/udhcpd.conf #udhcpc -i wlan0&
这样每次启动后都可以加载上驱动，具体什么原因还不清楚，有待考证。
二、wifi驱动加载正常，但是执行hostapd配置启动网卡和wifi时，出现SDIO相关的读写错误
在刚开机一段时间不会报错，运行一段时间后报错。猜测是和硬件设置相关的错误
执行./start_hostapd.sh，打印信息如下：
1 ~/wifi # ./start_hostapd.sh 2 Configuration file: /etc/hostapd_5G_1.conf 3 Could not set interface wlan0 flags (UP): Operation not permitted 4 nl80211: Could not set interface 'wlan0' UP 5 nl80211: deinit ifname=wlan0 disabled_11b_rates=0 6 nl80211 driver initialization failed. 7 wlan0: interface state UNINITIALIZED->DISABLED 8 wlan0: AP-DISABLED 9 wlan0: CTRL-EVENT-TERMINATING 10 hostapd_free_hapd_data: Interface wlan0 wasn't started

SDIO读写错误导致固件传输失败。
SDIO相关的设置主要在设备树中，根据以下链接，定位到SDIO的时钟频率问题，将其设置为140M或120M，就正常。
mmc3: SDIO@0x10120000 { compatible = "hisi-sdhci"; reg = <0x10120000 0x1000>; interrupts = <0 76 4>; clocks = <&clock HI3559AV100_MMC3_CLK>; clock-names = "mmc_clk"; resets = <&clock 0x23c 27>, <&clock 0x23c 29>, <&clock 0x23c 30>; reset-names = "crg_reset", "dll_reset", "sampl_reset"; max-frequency = <120000000>; crg_regmap = <&clock>; misc_regmap = <&misc_ctrl>; iocfg_regmap = <&ioconfig>; bus-width = <4>; cap-mmc-highspeed; sd-uhs-sdr104; devid = <3>; status = "disabled"; };
但是之前一直用的198M的SDIO接wifi，也没有这个问题，重新编译内核之后就出现这个问题，应该是还有其他地方设置不对。
以后要用到Mesh组网，SDIO的时钟还是要设置为198M。还是有待解决。
