s3c2440 + wince5.0 + sdio接口wifi 8686的调试记录

465 查看
前面调试sdio接口wifi的时候遇到了一些问题，现在整理记录一下。当时给的驱动是windowsmobile 6.0上用的，大概是pxa310上的驱动，不过我在网上搜索到MAVELL_WIFI的驱动，里面内容差不多，基本一样。
早期的时候，我对sd卡的驱动也不太熟悉，所以这部分虽然修改了，但是实际上检测sd卡的驱动部分就是错的，这时候会出来一些错误的信息，不过这也是调试的一个重要组成部分，有很多问题也能搜索到，但实际的原因可能并不准确。
最初的打印信息

这是最早的部分，只有这部分打印信息，没有弹出网络搜索框（出了就奇怪了）。于是开始网上搜索原因，把各种帖子都看了一下。开始尝试着修改注册表，来调整。

当时我是选择把这一部分打开，并修改一些对应的IRQ跟sdio的部分保持一致。这部分其实是我当时不太理解造成的。真正的加载，并没有通过这里，下面会介绍。这时候调试信息是这样的
-BSPIntrEnableIrq(irq = 35)

这个时候我以为看到曙光了，但其实大方向都是错误的了。当时注册表里确实加了这个驱动的部分信息，但它不是通过sdio加载的，是通过写的builtin里面直接加载的。然后sd卡驱动部分去读，结果就出错了。
从始至终打印信息，wifi的在sd卡之前。曾经我还以为，是因为sd卡驱动在wifi驱动之后导致的，其实不是。修改order并没有用处。这部分打印信息的前后其实没有问题。
然后得到了别人的帮助，看代码，弄明白了wifi不应该是这样加载。而是应该通过sdio驱动来加载。注册表里
; registry keys for the Streams portion of the driver
[HKEY_LOCAL_MACHINE/Drivers/SDCARD/ClientDrivers/Custom/MANF-02DF-CARDID-9103-FUNC-1]
"Dll"="SDIO8686.dll" ; use the "streams" interface portion to load the NDIS portion
"Prefix"="NDL"
; add instance key for each instance that can be added
"Instance0"="SDIO8686:SDIO86861" ; "InstanceX" = "<Miniport Name>:<Miniport Instance>"
才是正确的加载方式。
下面有了努力的方向，开始进行其他地方的修改。

这个时候这些错误，开始在网上找答案。有的说把
; 1:SDIO 4 bit mode; 0: SDIO 1 bit mode
"SetSD4BIT"=dword:1
改为 "SetSD4BIT"=dword:0，这个时候用的也没效果，后面因为这个还导致另一个问题。
有人说是RoamingMode 设为3，快速模式，改掉之后，没有效果。SDGPIOIntEnable改为0，通过这项选择用sdio的驱动来Set
the value to use GPIO pin as Interrupt pin, 1:use GPIO pin as interrupt source;
0:used SDIO bus 。还是启动到SDNdis: Failed to get active path key (0xC0000001)。下面是RoamingMode 设为3的打印信息

这些都测试了一下，当时都没有用。开始想其他的办法。
好了，上面都是错误的方法，错误的结果。下面才迈出了成功的第一步。前面刚看过wince.he的帖子，说调试的另一款wifi。当时觉得他是通过写了一个应用程序，手动来进行sd卡的插入拔出检测。询问了一下，知道是用注册表来实现的。
于是我开始重新修改SD卡的驱动，在线程里检测SD卡的部分，也通过读注册表来实现。把原来的 "NoDeviceCreate"=dword:1修改回来。这个时候前面就能够正常执行了，执行到
********SDIODownloadPkt**********
[MRVL] * ERROR, timeout (12000 sec) for waiting HW Spec!

INIT - Leave MrvDrvInitialize fail5
[MRVL] * ERROR, timeout (12000 sec) for
waiting HW Spec!产生错误。这个地方是InitializeWirelessConfig函数中出现的。
再往下面查，
在这个地方等待超时。我试着把这个地方不执行，直接返回TRUE。发现出现搜索框了，不过肯定是有问题的了，不能加入到网络，或者不稳定。这个因为有时候无线信号不太好，也没怎么具体试。
这个时候，找到了问题的原因，
; 1:SDIO 4 bit mode; 0: SDIO 1 bit mode
"SetSD4BIT"=dword:1
这个地方需要用4bit模式，以前改过的，现在要改回来。这样就完全可以了。

总结一下，其实我主要是前面SD卡检测就犯了错误，但是发现这些错误的一些打印信息还挺常见。正常的话，其实根据厂家提供的驱动，不需要怎么修改就可以成功的运行。
早期的时候，我对sd卡的驱动也不太熟悉，所以这部分虽然修改了，但是实际上检测sd卡的驱动部分就是错的，这时候会出来一些错误的信息，不过这也是调试的一个重要组成部分，有很多问题也能搜索到，但实际的原因可能并不准确。

}再往下面查，
DWORD WaitForSingleObjectWithCancel(PMRVDRV_ADAPTER pAdapter, HANDLE hEvent, DWORD dwTimeout)
{
HANDLE rgHandles[] = {hEvent, pAdapter->hEjectEvent};
DEBUGCHK(pAdapter);
return WaitForMultipleObjects(2,rgHandles,FALSE,dwTimeout);
}在这个地方等待超时。我试着把这个地方不执行，直接返回TRUE。发现出现搜索框了，不过肯定是有问题的了，不能加入到网络，或者不稳定。这个因为有时候无线信号不太好，也没怎么具体试。
这个时候，找到了问题的原因，
; 1:SDIO 4 bit mode; 0: SDIO 1 bit mode
"SetSD4BIT"=dword:1
这个地方需要用4bit模式，以前改过的，现在要改回来。这样就完全可以了。

总结一下，其实我主要是前面SD卡检测就犯了错误，但是发现这些错误的一些打印信息还挺常见。正常的话，其实根据厂家提供的驱动，不需要怎么修改就可以成功的运行。
