常见问答
NuMicro®家族芯片进行IAP(In-Application Programming)功能时，如何执行新程序？ 日期：2015-12-21
NuMicro®家族芯片进行IAP(In-Application Programming)功能时，可通过两种方式执行新的程序：
- 向量重映射后执行系统复位（System Reset）指令
代码如下：
FMC_SetVectorPageAddr(Application_BASE);
NVIC_SystemReset();
-
向量重映射后使用函数指针指向新的程序：
代码如下：func = (void (*)(void)) M32(Application_BASE + 4);
__asm __set_SP(Application_BASE);
func();
__asm __set_SP(uint32_t _sp)
{
MSR MSP, r0
BX lr
}
NuMicro®家族芯片向量重映射后，对两种方式的支持情况如下表所示：
