FAQ
How to execute a new program when using the IAP (In-Application Programming) function of the NuMicro® family? Issue Date：2015-12-21
When using the IAP (In-Application Programming) function of the NuMicro® family series, you can execute a new program in two ways:
- Perform System Reset after vector remapping:
FMC_SetVectorPageAddr(Application_BASE);
NVIC_SystemReset();
-
Use a function pointer to point to the new program after vector remapping:
func = (void (*)(void)) M32(Application_BASE + 4);
__asm __set_SP(Application_BASE);
func();
__asm __set_SP(uint32_t _sp)
{
MSR MSP, r0
BX lr
}
The following table shows the support condition of System Reset/CPU Reset or Function Pointer for each NuMicro® family series:
