加急～～新手面前有个坎！！！关于wince6.0 下的dm9000a驱动

jw1975 2008-10-17 18:12 楼主

如题，新手面前有个不小的坎，希望能有老手帮忙指点，谢谢啦～～～～～

这两天一直在做6400上的dm9000a的驱动，是在以前的2440的源码基础上修改的

这个板子的DM9000的CS#接在mpu的Xm0nCs4上，INT#接在XEINT9即af19引脚上，我查了下技术手册ncs4对应的地址是0x3000_0000，所以我在头文件中定义了它的基地址：

#define BSP_BASE_REG_PA_DM9000A_IOBASE       0x30000000
#define BSP_BASE_REG_PA_DM9000A_MEMBASE       0x30000000

不知道这样对不对，这里使用的地址应该还是物理地址吧，还有那个MEMBASE该如何确定，是不是与IOBASE一致？

我又将IRQ设为9：
CONFIG_PARAMETER g_szDm9ConfigParams[] =
{
               。
                  。
                  。
{ CID_IRQ_NUMBER, 9, NDIS_STRING_CONST("IrqNumber")},
               。
                  。
                  。
};

再后来按照readme修改project.bib和project.reg。下面是我的改的reg：

[HKEY_LOCAL_MACHINE\Windows CE Tools]
  "Platform"="{a6e36254-01d9-408b-ac00-a0e76270fcd2}"

      [HKEY_LOCAL_MACHINE\Comm\DM9CE]
         "DisplayName"="DM9000 ISA Fast Ethernet Adapter"
         "Group"="NDIS"
         "ImagePath"="dm9isa.dll"

      [HKEY_LOCAL_MACHINE\Comm\DM9CE\Linkage]
         "Route"=multi_sz:"DM9CE1"

      [HKEY_LOCAL_MACHINE\Comm\DM9CE1]
         "DisplayName"="DM9000 ISA Fast Ethernet Adapter"
         "Group"="NDIS"
         "ImagePath"="dm9isa.dll"

      [HKEY_LOCAL_MACHINE\Comm\Tcpip\Linkage]
         "Bind"="dm9ce1"

      [HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms]
   "BusNumber"=dword:0
   "BusType"=dword:1
         "XmitBuffer"=dword:20
         "RecvBuffer"=dword:20

   "SysIntr"=dword:19
"IoAddress"=dword:30000000

      [HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms\TcpIp]
         "EnableDHCP"=dword:1
         "UseZeroBroadcast"=dword:0
         "DefaultGateway"="192.168.1.1"
         "IpAddress"="192.168.1.119"
         "Subnetmask"="255.255.255.0"
         "DNS"="210.21.196.6"
         "WINS"=""
[HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms]
"MACAddress"="00-11-22-33-44-55"

接着就是编译，下载，但老是说它是unknown device

dm9000 init.
vals are C8E0C8E0
val1  = DeviceReadPort(DM9_VIDL); is
   8
val1 |= ((DeviceReadPort(DM9_VIDH)<<8)-0x100); is
808
val2  = DeviceReadPort(DM9_PIDL); is
      A
val2 |= ((DeviceReadPort(DM9_PIDH)<<8)-0x100); is
   A0A
Unknown device
[dm9]: Chip signature is 808 A0A
[dm9]: IRQ= 0x64
MAC address:00-11-22-33-44-55
-OALIntrRequestSysIntr(irq = 100, sysIntr = 22)
Where am I???????????[UFNPDD] USB Serial Function Class Enabled
[USB] dii.dwIrq = 96

-OALIntrRequestSysIntr(irq = 96, sysIntr = 23)
Where am I???????????Current Client "Serial_Class"
[UFNPDD] USB Serial Function Class Enabled
[UFNPDD] OTG Cable Attached

里面有部分输出是我自己添加的，用来查看val。下面是是我修改的这部分代码：

void C_DM9000::EDeviceRegisterIoSpace(void)
{
RETAILMSG(1,(TEXT("\r\ndm9000 init.\r\n")));
NIC_DEVICE_OBJECT::EDeviceRegisterIoSpace();
U16 val1,val2,t_v1;//t_v2;
#ifdef TEST
RETAILMSG(1,(TEXT("vals are %0X%4X\r\n"), val1,val2));//0xc900 0xc900
#endif
val1 = DeviceReadPort(DM9_VIDL); //
#ifdef TEST
RETAILMSG(1,(TEXT("val1 = DeviceReadPort(DM9_VIDL); is\n\t %0X\r\n"), val1));
#endif
//t_v1 = DeviceReadPort(DM9_VIDH)<<8;
//RETAILMSG(1,(TEXT("t_v1 loop 8:%0X\r\n"), t_v1));
val1 |= ((DeviceReadPort(DM9_VIDH)<<8)-0x100);//
//val1 -=0x100;
#ifdef TEST
RETAILMSG(1,(TEXT("val1 |= ((DeviceReadPort(DM9_VIDH)<<8)-0x100); is\n\t%0X\r\n"), val1));
#endif
val2 = DeviceReadPort(DM9_PIDL); //
#ifdef TEST
RETAILMSG(1,(TEXT("val2 = DeviceReadPort(DM9_PIDL); is\n\t %4X\r\n"), val2));
#endif
val2 |= ((DeviceReadPort(DM9_PIDH)<<8)-0x100); //
//val2 -=0x100;
#ifdef TEST
RETAILMSG(1,(TEXT("val2 |= ((DeviceReadPort(DM9_PIDH)<<8)-0x100); is\n\t %4X\r\n"), val2));
#endif
if( (val1 != DM9000_VID) || (val2 != DM9000_PID))
{
RETAILMSG(1,(TEXT("Unknown device\r\n")));
RETAILMSG(1,(TEXT("[dm9]: Chip signature is %0X%4X\r\n"), val1,val2));
RETAILMSG(1,(TEXT("[dm9]: IRQ= 0x%02X\r\n"), m_szConfigures[CID_IRQ_NUMBER]));
}
}

上面代码中减去0x100是因为我认为之前的版本（val2 |= DeviceReadPort(DM9_PIDH)<<8；）并没有达到将val中存储的8位数据自身复制组成U16类型的目的，就是说把0x08转换成0x808。

最终结果是，DNW 输出unknown device,系统中却又网络图标，但是接上网络，接头上的等不闪。
