07-21 06:11:44.806   292   292 E android.hardware.wifi@1.0-service: Wifi driver is not ready.: Success

这里显示我的驱动没有成功，从这里可以确定驱动部分是有问题的，驱动部分就有SDIO接口，所以折个是后就要去确定SDIO 驱动是不是跑起来了，如果没有就要在设备树中添加节点，使能SDIO驱动

2. 调试分享

2.1确定SDIO通信是否正常

下面是我的sdio配置：

根节点下：sdio_pwrseq: sdio-pwrseq {compatible = "mmc-pwrseq-simple";clocks = <&rk809 1>;clock-names = "ext_clock";pinctrl-names = "default";pinctrl-0 = <&wifi_enable_h>;/** On the module itself this is one of these (depending* on the actual card populated):* - SDIO_RESET_L_WL_REG_ON* - PDN (power down when low)*/post-power-on-delay-ms = <200>;reset-gpios = <&gpio2 RK_PB1 GPIO_ACTIVE_LOW>;};

//for ap6256-wifi
&sdmmc1 {max-frequency = <150000000>;//max-frequency = <50000000>;supports-sdio;bus-width = <4>;disable-wp;cap-sd-highspeed;//cap-sdio-irq;keep-power-in-suspend;mmc-pwrseq = <&sdio_pwrseq>;non-removable;pinctrl-names = "default";pinctrl-0 = <&sdmmc1_bus4 &sdmmc1_cmd &sdmmc1_clk>;sd-uhs-sdr104;status = "okay";
};

添加了上面的节点发现还是不行，于是查看SDIO驱动是否成功

[    5.329780] dhd_module_init: in Dongle Host Driver, version 1.579.77.41.22 (r-20191105-2)(20191120-1)

[   10.100392] dhd_module_init: Exit err=-19
sbc_rk3568:/ # cat d/gpio

从这里看出来还是驱动部分有问题，量了SDIO数据也没有
io_list中有上面这个sdio的reset控制引脚，如果这个脚不能受控制那SDIO就起不来，

SDMMC1_PWREN/I2C4_SDA_M1/UART8_RTSn_M0/CAN2_RX_M1/GPIO2_B1_d

根据上面的复用功能，我逐个排查看是否复用最后发现I2C4打开了，这肯定不行，果断关掉

后来检测供电发现我一个供电没有改到，更改后WIFI正常

&pmu_io_domains {status = "okay";pmuio2-supply = <&vcc3v3_pmu>;vccio1-supply = <&vccio_acodec>;vccio3-supply = <&vccio_sd>;vccio4-supply = <&vcc_1v8>;    //更改这里vccio5-supply = <&vcc_3v3>;vccio6-supply = <&vcc_3v3>;vccio7-supply = <&vcc_3v3>;
};

成功后的dhd正常打印：

3.瑞星微提供的调试方法

首先确认开机后系统是否有 USB WIFI 或者 SDIO wifi 设备,正常开机后,可以首先通过内核
log 进行确认,如果是 sdio,wifi 内 log 会有如下 sdio 识别成功 log:

如果是 usb,wifi 会有类似如下 usb 信息:

If it is usb, wifi will have the usb information similar as below:
usb 2-1: new high-speed USB device number 2 using ehci-platform
usb 2-1: New USB device found, idVendor=0bda, idProduct=b82c
usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-1: Product: 802.11ac NIC

如果 usb 信息和 sdio 扫卡成功 log 信息都没有,那说明 wifi 模块没有正常上电或者 sdio 扫卡
异常,需要再次确认硬件是否有问题以及软件 dts 里面 wifi 管脚是否正确配置;因为开机对模块成
功上电是检测 wifi 芯片 id 的前提
另外也可以 cat 如下路径下的 uevent 文件进行确认:

Besides, you can also cat the uevent file in the following path to confirm:
sys/bus/sdio/devices
sys/bus/usb/devices

如果模块正常上电,也可以识别到 wifi 模块的 vid pid,再确认是否正确加载 wifi ko 驱动文件;

以 AP6255 wifi 模块为例

sbc_rk3568:/sys/bus/sdio/devices # cd ./
sbc_rk3568:/sys/bus/sdio/devices #lsmod
Module                  Size  Used by
bcmdhd               1175552  0

注意:由于目前 wifi 驱动是采用 ko 方式,如果有修改内核网络相关配置,一定要重新编译
ko,否则很可能加载 wifi ko 引起内核 panic

4. WIFI 芯片识别流程

开机对 wifi 模块上电,并自动进行扫描 sdio 操作。
Power up wifi module, and automatically scan sdio.
系统启动打开 wifi 操作时,分别对系统 sys/bus/sdio(sdio wifi), sys/bus/usb(usb wifi)sys/bus/pic (pcie wifi )文件系统下的 uevent 进行读取
获取到 wifi 芯片 vid pid 加载相应的 wifi ko 驱动
识别到 wifi 类型后加载不同的 wpa_supplicant 参数启动 wifi。

核心代码目录:
android /frameworks/opt/net/wifi
kernel/net/rfkill/rfkill-wlan.c
hardware/broadcom
external/wpa_supplicant_8

5.WIFI移植

RK 平台上所有的 WIFI 模块驱动都是放到内核 kernel/drivers/net/wireless/rockchip_wlan 目录,一般移植新的 WIFI 驱动,需要在 kernel/drivers/net/wireless 目录添加相应的 wifi 模块的 Kconfig 和Makefile,有的模块还需要修改 wifi 驱动的 Kconfig 和 Makefile(根据特定的 wifi 模块驱动)
内核能正确编译出 wifi ko 驱动文件,wifi ko 文件在编译 kernel 的时候会自动编译。
注意:由于目前 wifi 驱动是采用 ko 方式,如果有修改内核网络相关配置,一定要重新编译ko,否则很可能导致 wifi ko 和内核网络协议栈不匹配。

6.WIFI兼容

1.添加 wifi 名称和 wifi vid pid
源码路径:frameworks/opt/net/wifi/libwifi_hal/rk_wifi_ctrl.cpp 代码 supported_wifi_devices[]结
构体中添加 wifi 模块的名称和对应 vid pid, vid pid 可以根据下面章节手动读取 uevent 进行查看;
以 AP6255 为例:AP6255 为模块名称,02d0:09bf 为 vid pid
如下列表中已经添加了几款 wifi 的
兼容,参考如下格式添加:

typedef struct _wifi_devices
{char wifi_name[64];char wifi_vid_pid[64];
} wifi_device;static wifi_device supported_wifi_devices[] = {{"RTL8188EU",   "0bda:8179"},{"RTL8188EU",  "0bda:0179"},{"RTL8723BU",  "0bda:b720"},{"RTL8723BS",  "024c:b723"},{"RTL8822BS",  "024c:b822"},{"RTL8723CS",  "024c:b703"},{"RTL8723DS",  "024c:d723"},{"RTL8188FU",  "0bda:f179"},{"RTL8822BU",  "0bda:b82c"},{"RTL8189ES",  "024c:8179"},{"RTL8189FS",  "024c:f179"},{"RTL8192DU",  "0bda:8194"},{"RTL8812AU",  "0bda:8812"},{"RTL8821CS",  "024c:c821"},{"RTL8822CU",   "0bda:c82c"},{"RTL8822CS",   "024c:c822"},{"SSV6051",  "3030:3030"},{"ESP8089",    "6666:1111"},{"AP6354", "02d0:4354"},{"AP6330", "02d0:4330"},{"AP6356S",    "02d0:4356"},{"AP6335", "02d0:4335"},{"AP6255",      "02d0:a9bf"},{"RTL8822BE", "10ec:b822"},{"MVL88W8977", "02df:9145"},{"SPRDWL", "0000:0000"},
};

添加 wifi 驱动 ko 文件存放路径
frameworks/opt/net/wifi/libwifi_hal/wifi_hal_common.cpp 中 wifi_ko_file_name module_list[]结构体存放的是 wifi 模块的 ko 驱动存放路径和加载 wifi ko 驱动所需的参数, wifi ko 存放路径统一采用 XXXX_DRIVER_MODULE_PATH 的命名方式,如果 ismod wifi ko 不需要带参数,那么可以使用 UNKKOWN_DRIVER_MODULE_ARG,注意:wifi 名称supported_wifi_devies[]结构体中定义的名称一样

3.添加 wpa_supplicant 启动参数 Add wpa_supplicant start parameter
init.connectivity.rc 中启动 wpa_supplicant 参数从/vendor/etc/wifi/wpa_config.txt 文件中读取
该文件如下：

sbc_rk3568:/vendor/etc/wifi $ cat wpa_config.txt
wpa_config.txt
[broadcom]
/vendor/bin/hw/wpa_supplicant
-O/data/vendor/wifi/wpa/sockets
-puse_p2p_group_interface=1
-g@android:wpa_wlan0[realtek]
/vendor/bin/hw/wpa_supplicant
-O/data/vendor/wifi/wpa/sockets
-g@android:wpa_wlan0[ssv]
/vendor/bin/hw/wpa_supplicant
-O/data/vendor/wifi/wpa/sockets
-g@android:wpa_wlan0[esp]
/vendor/bin/hw/wpa_supplicant
-O/data/vendor/wifi/wpa/sockets
-puse_p2p_group_interface=1
-g@android:wpa_wlan0[mvl]
/vendor/bin/hw/wpa_supplicant
-O/data/vendor/wifi/wpa/sockets
-g@android:wpa_wlan0

wpa_config.txt 代码中存放在 deivice/rockchip/common/wpa_config.txt
wpa_supplicant/main.c 中 main 函数入口会根据芯片类型来选择读取不同的 wpa_supplicant 参数,该文件的路径：external/wpa_supplicant_8/wpa_supplicant
以 broadcom 模块为例:
当读取到芯片是 APxxx 系列的,就会根据 BROADCOM_MODULE_NAME 在/vendor/etc/
wifi/wpa_config.txt 文件中查找 broadcom 模块的参数。
