最近在搞STM8的IAP，想在Bootloader与APP中都用中断，看来网上的大神说的方案，可以将中断向量重定向到RAM，可是搞了两天仍然没有搞定，按如下的方法，BOOT单独可以正常串口中断（屏蔽了跳转到APP）而BOOT跳转到APP就不能中断，感觉APP中的中断向量重定向有点问题，但是又不知道问题在哪，特来求助各位大神
boot:
icf文件
define region NearData = [from 0x0000 to 0x077F];
define region Eeprom = [from 0x4000 to 0x43FF];
define region BootROM = [from 0x6000 to 0x67FF];
define region NearFuncCode = [from 0x8000 to 0xA7FF];
define region FarFuncCode = [from 0x8000 to 0xA7FF];
define region HugeFuncCode = [from 0x8000 to 0xA7FF];
bOOT里的主要代码：
#if 1
typedef void(*isr_type_t)(void);
typedef struct{
       uint16_t interrupt_instuction;
       isr_type_t interrupt_handler;
}interrupt_vector;
#pragma location=0x0780
interrupt_vector vector_table_[32];
#endif
#pragma vector=23
__interrupt void UART2_RX_IRQ(void)
{
  ........//中断
}
void main(void)
{
    vector_table_[23].interrupt_instuction=0x8200;
    vector_table_[23].interrupt_handler=(isr_type_t)&UART2_RX_IRQ;
}
APP：
icf文件
define region NearData = [from 0x0000 to 0x077F];
define region Eeprom = [from 0x4000 to 0x43FF];
define region BootROM = [from 0x6000 to 0x67FF];
define region NearFuncCode = [from 0xA800 to 0xFFFF];
define region FarFuncCode = [from 0xA800 to 0xFFFF];
define region HugeFuncCode = [from 0xA800 to 0xFFFF];
APP中部分代码
重定向
#pragma location=0x0780
uint32_t vector_table_[32];

   vector_table_[0]=0x82008080;
   for(i=1;i<32;i++)
    {
     vector_table_=(0X82000000+0xA800+(i*4));
    }

可以参考stm8s tinyboot
