为什么我的Marvel8686 wifi在Android打开wifi开关的时候回会不停的去加载wifi驱动？

为什么我的Marvel8686 wifi在Android打开wifi开关的时候回会不停的去加载wifi驱动？ [复制链接]

间隔一秒加载如下东西：

libertas_sdio: Libertas SDIO driver++

libertas_sdio: Libertas SDIO driver--

init: start ~~~~~~~~ wpa_supplicant:-iwlan0 -c/data/misc/wifi/wpa_supplicant.conf

ADDRCONF(NETDEV_UP): wlan0: link is not ready




——这个有两个可疑的地方

1、ADDRCONF(NETDEV_UP): wlan0: link is not ready

2、 (unregistered net_device)
先分别查一下，到底是什么原因产生的吧。

root@linux-virtual:/IData/s5pv210/f210/kernel# grep 'unregistered net_device' * -r
Binary file arch/arm/boot/Image matches

include/linux/netdevice.h:                return "(unregistered net_device)";




static inline const char *netdev_name(const struct net_device *dev)
{
        if (dev->reg_state != NETREG_REGISTERED)

                return "(unregistered net_device)";
        return dev->name;
}

看看这个函数是怎么被调用的吧，慢慢找上去。



今天仔细有发现，就是发现几个关键的字眼“Turning Wi-Fi on…"和Turning off Wi-Fi的字眼，看他们是在这里设置的





packages/apps/Settings/res/values-en-rGB/strings.xml:    "Turning Wi-Fi on…"

packages/apps/Settings/res/values/strings.xml:    Turning Wi-Fi on\u2026

  "wifi_stopping">Turning off Wi-Fi\u2026







继续找...................wifi_stopping和"wifi_starting

这个好像，是插入卡，就频繁的通过CD引脚检测中断引起加载wifi libertas_sdio.ko
模块，但是如果一旦加载一次这个模块驱动，下次加载就会提示已经存在，这里重复加载意味着这个加载一次后又卸载了，然后又再次加载？！怎么会这样呢？

最近我也在搞W8686的驱动，板子是tiny210, 系统是2.6.35.7。
驱动应该是加载成功的。用iwlist wlan0 scan可以搜索到周围的AP.
1.执行 ifconfig wlan0 up的时候也会提示ADDRCONF(NETDEV_UP): wlan0: link is not ready。再执行这个命令的时候又不提示了。
2.  wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf 提示这个conf文件不能读或解析。
目前没有什么进展。

tiny210 不是已经支持Marvel8686 了吗，为啥你还要自己搞？

2、是否是权限问题？

看了一下wifi的整个工作流程，终于找到了一些蛛丝马迹

private boolean setWifiEnabledBlocking(boolean enable, boolean persist, int uid) {
if (enable) {
            if (!WifiNative.loadDriver()) {               
                setWifiEnabledState(WIFI_STATE_UNKNOWN, uid);
            }
           if (!WifiNative.startSupplicant()) {
                WifiNative.unloadDriver();              ——串口终端不停的打印加载libertas_sdio.ko,说明之前必然有一个卸载libertas_sdio.ko模块的程序被执行了，应该就是这里！
                setWifiEnabledState(WIFI_STATE_UNKNOWN, uid);
            }
            registerForBroadcasts();
            mWifiStateTracker.startEventLoop();
        } else {
  ………………
  }
    // Success!        
       setWifiEnabledState(eventualWifiState, uid);
}




不管有多难，总会找到一些出问题的地方的。

----------------------------------
貌似代码改了

        private boolean connectToSupplicant() {
            int connectTries = 0;

            while (true) {
                if (WifiNative.connectToSupplicant()) {
                    return true;
                }
                if (connectTries++ < 5) {
                    nap(1);
                } else {
                    break;
                }
            }
            return false;
        }
