HELP！关于rtl8189es在JB4.2.2上的porting

[jiangshao]

尊敬的FAE

我有一块客户根据NXP（Freescale）的sabresd_mx6dq设计的开发板，使用的是SDIO接口的

Rtl8189es，OS为Android4.2.2. 在porting过程中遇到了一些问题，急需您的帮助！

驱动：RTL8188EUS_RTL8189ES_linux_v4.1.8_9499.20131104.zip

参考文档：android_ref_codes_JB_4.2/Realtek_Wi-Fi_SDK_for_Android_JB_4_2.pdf

移植过程基本完全参照Realtek_Wi-Fi_SDK_for_Android_JB_4_2.pdf。

• external/wpa_supplicant_8用驱动提供的2_rtw_r8680.20130821.tar.gz替代
• hardware下对应文件也用驱动提供的2_20130208.tar.gz替代
• kernel_imx/drivers/net/wireless/rtl8189es下放置1.8_9499.20131104.tar.gz解压后的内容
• 根据文档修改rc， BoardConfig.mk等文件，修改kernel_imx/drivers/net/wireless/下的Kconfig和Makefile
• 内核配置中选择编译8189es为模块
• 手动将h的内容覆盖到kernel_imx/drivers/net/wireless/rtl8189es/include/autoconf.h

编译安卓后烧写固件到开发板中。

在安卓的设置-》Wi-Fi-》移动滑块

现象：滑块变为打开，右侧显示正在打开Wi-Fi…，大约几秒后，滑块重新变为关闭

如果用logcat监视，可见如下信息：

D/WifiService( 2503): setWifiEnabled: true pid=2766, uid=1000

D/BluetoothAdapter( 2766): 1089157384: getState() :  mService = null. Returning STATE_OFF

E/WifiStateMachine( 2503): DriverFailedState

D/BluetoothAdapter( 2766): 1089157384: getState() :  mService = null. Returning STATE_OFF

串口控制台有如下输出：

RTL871X: module init start version:v4.1.8_9499.20131104

RTL871X: rtl8189es driver version=v4.1.8_9499.20131104

RTL871X: build time: Oct 27 2016 13:15:52

RTL871X: module init ret=0

RTL871X: module exit start

RTL871X: module exit success

从现象来看，在试图打开wifi时，module先被init，且顺利完成（？）

但是因为找不到wlan0和p2p0，导致load_driver: get wifi_ifname(PRIMARY) fail（？）

最终module exit start

这大概是哪里的问题呢？

我曾经试图让printk输出更多信息，但是

cat proc/sys/kernel/printk

输出为

15    4    1    7

这个15很让人费解，但是似乎已经是输出所有信息了。。。

最近又测试了一个更新版本的驱动，错误依旧。

所以现在有些怀疑是不是：

1，硬件连接问题：在和wifi模块厂家确认

2，板文件设置问题？

目前8189es接在了SD2，板文件中定义如下：

static const struct esdhc_platform_data mx6q_sabresd_sd2_data __initconst = {
.cd_gpio = SABRESD_SD2_CD,
.wp_gpio = SABRESD_SD2_WP,
.keep_power_at_suspend = 1,
// change by shao, 2016-09-21, for rtl8189es
//.support_8bit = 1,
.support_8bit = 0,
.delay_line = 0,
.cd_type = ESDHC_CD_CONTROLLER,
.runtime_pm = 1,
};

不知有没有不妥的地方？

[jimmychan]

wp is not use. you can remove the .wp_gpio = SABRESD_SD2_WP,

[jiangshao]

非常感谢，我按照您的提示修改如下，

static const struct esdhc_platform_data mx6q_sabresd_sd2_data __initconst = {
//.cd_gpio = SABRESD_SD2_CD,
//.wp_gpio = SABRESD_SD2_WP,
.always_present = 1,
.keep_power_at_suspend = 1,
//change by shao, 2016-09-21, for rtl8189es
//.support_8bit = 1,
.support_8bit = 0,
.delay_line = 0,
//.cd_type = ESDHC_CD_CONTROLLER,
.cd_type = ESDHC_CD_PERMANENT,
//.runtime_pm = 1,
};

错误有了变化，似乎wlan0出现了，但是p2p0还是没有。。。

[jimmychan]

maybe the name setting here is not match in your system:

WIFI_DRIVER_MODULE_NAME := "wlan"
WIFI_DRIVER_MODULE_PATH := "/system/lib/modules/wlan.ko"
WIFI_DRIVER_MODULE_ARG := "ifname=wlan0 if2name=p2p0"

please check the BoardConfig.mk

[jiangshao]

我们的BoardConfig.mk定义如下：

WPA_SUPPLICANT_VERSION := VER_0_8_X
BOARD_WPA_SUPPLICANT_DRIVER := NL80211
CONFIG_DRIVER_WEXT := y
#CONFIG_DRIVER_NL80211 :=true
BOARD_WPA_SUPPLICANT_PRIVATE_LIB := lib_driver_cmd_rtl
BOARD_HOSTAPD_DRIVER := NL80211
BOARD_HOSTAPD_PRIVATE_LIB := lib_driver_cmd_rtl
BOARD_WLAN_DEVICE := rtl8189es

WIFI_DRIVER_MODULE_NAME := "8189es"
WIFI_DRIVER_MODULE_PATH := "/system/lib/modules/8189es.ko"
WIFI_DRIVER_MODULE_ARG := "ifname=wlan0 if2name=p2p0"

且我已将make modules得到的8189es.ko放入/system/lib/modules/

另外，如果我选择把8189不编译成ko，而是编译进内核，

logcat有如下错误：

D/WifiService( 2579): setWifiEnabled: true pid=2873, uid=1000
D/BluetoothAdapter( 2873): 1108199328: getState() : mService = null. Returning STATE_OFF
E/WifiStateMachine( 2579): Failed to load driver!
E/WifiStateMachine( 2579): DriverFailedState
D/BluetoothAdapter( 2873): 1108199328: getState() : mService = null. Returning STATE_OFF

从dmesg的输出来看

<4>RTL871X: module init start
<4>RTL871X: rtl8189es v4.3.18.1_15373.20151005
<4>RTL871X: build time: Nov 7 2016 15:17:23
<4>RTL871X: module init ret=0

驱动的版本都已经被识别，应该是驱动被找到了。。。

Basically, this is realtek driver issue. It is better to consult realtek for the driver solution using in Android.

Jimmy 你好！

我现在也碰到了找不到wlan0的问题，请问你是怎么解决的！

[jiangshao]

附件是全部log，请参考

[jimmychan]

Can you show the full logcat (from the board boot up to this issue occur)?

[jiangshao]

刚才上传了log，从3098行开始
