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
  1. 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

3.Wifi 模块与相应 ko 相应的对应关系:

模块名称 ko 名称
AP6xxx(SDIO) bcmdhd.ko
RTL8723BU(USB) 8723bu.ko
RTL8188EU(USB) 8188eu.ko
RTL8188EU(USB) 8188fu.ko
RTL8723BS(SDIO) 8723bs.ko
RTL8723CS(SDIO) 8723cs.ko
RTL8723DS(SDIO) 8723ds.ko
RTL8189ES(SDIO) 8189es.ko
RTL8189FS(SDIO) 8189fs.ko

详细的 ko 和模块对应关系详见 android/frameworks/opt/net/wifi/libwifi_hal/wifi_hal_common.
cpp 文件。
系统 ko(ap6256的) 文件存放路径如下:

sbc_rk3568:/vendor/lib/modules # ls -l
total 18084
-rw-r--r-- 1 root root 3910536 2022-07-21 07:28 8723cs.ko
-rw-r--r-- 1 root root 4979920 2022-07-21 07:28 8821cs.ko
-rw-r--r-- 1 root root 6637152 2022-07-21 07:28 8822bs.ko
-rw-r--r-- 1 root root 2186448 2022-07-21 07:28 bcmdhd.ko
-rw-r--r-- 1 root root 1316880 2022-07-21 07:28 mali_kbase.ko
-rw-r--r-- 1 root root     801 2022-07-21 07:28 modules.alias
-rw-r--r-- 1 root root     159 2022-07-21 07:28 modules.dep
-rw-r--r-- 1 root root      54 2022-07-21 07:28 modules.load
-rw-r--r-- 1 root root      55 2022-07-21 07:28 modules.softdep

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

  1. 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.
  2. 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
  3. 获取到 wifi 芯片 vid pid 加载相应的 wifi ko 驱动
  4. 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"},

	{"RTL8189ES",	"024c:8179"},
	{"RTL8189FS",	"024c:f179"},
	{"RTL8192DU",	"0bda:8194"},
	{"RTL8812AU",	"0bda:8812"},
	{"RTL8821CS",	"024c:c821"},
        {"RTL8822CU",   "0bda:c82c"},
	{"RTL8822CS",   "024c:c822"},
	{"SSV6051",	"3030:3030"},

	{"AP6354",	"02d0:4354"},
	{"AP6330",	"02d0:4330"},
	{"AP6356S",	"02d0:4356"},
	{"AP6335",	"02d0:4335"},
	{"AP6255",      "02d0:a9bf"},

	{"MVL88W8977",	"02df:9145"},
	{"SPRDWL",	"0000:0000"},
};
  1. 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。

[broadcom]
/vendor/bin/hw/wpa_supplicant

-puse_p2p_group_interface=1
