实在硬件错误一定是堆栈问题，死在中断，可能是重映射问题。

重映射是这样吗：
SCB->VTOR = APP_START_SECTOR & 0x1FFFFF80;？

#define APP_START_SECTOR 0x0000A000

NVIC_SetVectorTable(DC_BOOT_SADDR, DC_BOOT_SIZE); // 中断向量重映射

这是STM32上的，有用的也是SCB->VTOR = NVIC_VectTab|(Offset & (u32)0x1FFFFF80);//设置NVIC 的向量表偏移寄
1788库函数找不到NVIC_VectTab，我看到有个网友写的1768的IAP，就是SCB->VTOR = APP_START_SECTOR & 0x1FFFFF80;这么写的
