今天使用了论坛中的最新IAP程序，见贴，
程序是烧进了芯片，但发现定时器0的中断无法响应？不知何故？
应用程序作了如下修改：
[1]linkarm_flash.xcl中 DROMSTART = 0x40000000 改为 0x40004000
[2]71x_init.s中注释了EIC_INIT;
[3]在应用程序的初始化程序中加入了如下代码？
extern u32 T0TIMI_Addr;
u32 * p = (u32 *)& T0TIMI_Addr;
u8 bCounter;
u32 offset;
EIC->ICR = 0x00000000;
EIC->IER = 0x00000000;
EIC->IPR = 0xFFFFFFFF;
EIC->FIR = 0x0000000C;
EIC->CIPR = 0x00000000;
EIC->IVR = 0xEA000000;
for(bCounter = 0; bCounter < 32; bCounter++)
{
offset = (((*p)&0xffff) + 0x7E0) >> 2;
p++;
EIC->SIR[bCounter] = offset << 16;
}
[4]IDE中的设置，生成raw-binary
由于应用程序中参考了AN1799_使用STR71x的通用IO驱动一个4X4的矩阵键盘中的如下代码，是否有影响？
// EIC configuration
// Initialize the interrupt controller
EIC_Init();
// Set the Timer 0 interrupt channel priority level to 1
EIC_IRQChannelPriorityConfig(T0TIMI_IRQChannel, 1);
// Enable the Timer 0 IRQ channel interrupts
EIC_IRQChannelConfig(T0TIMI_IRQChannel, ENABLE);
// Set the XTI interrupt channel priority level to 2
EIC_IRQChannelPriorityConfig(XTI_IRQChannel, 2);
// Enable the XTI IRQ channel interrupts
EIC_IRQChannelConfig(XTI_IRQChannel, ENABLE);
// Enable IRQ interrupts
EIC_IRQConfig(ENABLE);
// Configure the External Interrupt Unit
// Initialize the XTI
XTI_Init();
// Configure the line 2, 3, 4 and 5 edge.
XTI_LineModeConfig(XTI_Line2|XTI_Line3|XTI_Line4|XTI_Line5, XTI_RisingEdge);
// Enable the line 2, 3, 4 and 5 interrupt.
XTI_LineConfig(XTI_Line2|XTI_Line3|XTI_Line4|XTI_Line5, ENABLE);
// Enable Interrupt.
XTI_ModeConfig(XTI_Interrupt, ENABLE);
// TIM0 configuration
// Configure the Prescaler to 0x04 to get an Overflow interrupt every 5.120 ms
// This will gives an update rate of 48.8 Hz
// Inisialize the Timer 0
TIM_Init( TIM0 );
// Configure the Timer 0 prescaler
TIM_PrescalerConfig(TIM0, 0x02);
// Enable the Overflow Interrupt
TIM_ITConfig(TIM0, TIM_TO_IT, ENABLE);
// Start the TIM0 Counter
TIM_CounterConfig(TIM0, TIM_START);
