STM32F407VET6  FSMC接口驱动 DM9000的问题，PD7 接做为片选，PD11做为指令与数据的
代码如下：

#define DM9000_DATA  *(vu16*)((u32)0x60000000)
#define DM9000_CMD *(vu16*)((u32)0x60020000)

注意红色部分，如果是PD7，应该选择FSMC_Bank1_NORSRAM1而不是FSMC_Bank1_NORSRAM2，但是为FSMC_Bank1_NORSRAM1 的时候，就会死在
//Hard Fault exception handler
void HardFault_Handler(void)
{
while (1)
{
}
}这里面，改为FSMC_Bank1_NORSRAM2就正常了，请是怎么一回事呢？
有遇到这个情况的朋友吗？
