麻烦指点：关于dm9000a在2440-wince5.0下的设置错误

我用的是2440、wince5.0的板子。外部中断用的EINT7，CMD连在ADR2上，片选为nGCS3。
现在DM9000a的34引脚‘INT’一直为低，即是没有中断信号。LCD触摸屏会在有片选时卡住，就是屏上出现黑线，并无法通过输入，即：鼠标无法移动，按键没用。我觉得就是dm9000a的中断导致的问题，使内核被dm9000a占用过长。

在Platform.reg的dm9000a的注册信息中：（如下）
[HKEY_LOCAL_MACHINE\Comm\DM9CE1\Parms]
"BusNumber"=dword:0
"BusType"=dword:0
"XmitBuffer"=dword:20
"RecvBuffer"=dword:20
"IrqNumber"=dword:0d        
"SysIntr"=dword:12            
"IoAddress"=dword:18000000
"NetworkAddress"="e0aac8de6351"

其中"IrqNumber"应该怎么计算呢，是哪些参数的和呢？或者在哪个函数里查看相关参数？
"SysIntr"的值是SysIntr_firmware+2，即是16+2。应为在bsp_cfg.h中有sysintr_ether  (sysintr_firmware+2)。
我觉得中断的问题似乎就是出在这里的设置上。麻烦说的详细点。

现在在烧入内核时出现了这样的错：
。。。

麻烦大家帮忙分析一下，多谢了。
