各位大神，我最近在搞IAP在线升级，我碰到的问题是IAP跳转到APP程序后执行完一遍while循环后又返回到IAP程序了。APP程序就是个流水灯的小程序。

[mw_shl_code=c,true]void WR_IAP_TO_FLASH(void) { if(g_SysStatus.JumpToApp==0)return; if(((*(vu32*)(FLASH_APP1_ADDR+4))&0xFF000000)==0x08000000)//??????·???0X08XXXXXX. ????????FLASH_APP1_ADDR+4????????????·????????ò??±í(APP???ò?????????·) { iap_load_app(FLASH_APP1_ADDR);//????FLASH APP?ú?? }else{ #ifdef DEBUG DebugStrPrint("Illegal FLASH APP!\r\n"); #endif return; } }[/mw_shl_code]

[mw_shl_code=c,true]void iap_load_app(u32 appxaddr) { if(((*(vu32*)appxaddr)&0x2FFE0000)==0x20000000) //?ì?é???????·??·???·¨. { delay_us(5000); //??×??®?°?????ù?????? // SysTick_ITConfig(DISABLE); CloseIQHard(); // jump2app=(iapfun)*(vu32*)(appxaddr+4); //???§?ú??????????×???app???ò???????·(???????·) iapfun---???????? //appxaddr+4 ???·????????APP???ò?????ò?? //jump2app=(iapfun)*(vu32*)(appxaddr+4)??°?APP???????ò??×????????????? //°?jump2app×????????????? MSR_MSP(*(vu32*)appxaddr); //??????APP????????(???§?ú????????????×???????·????????·) jump2app(); //??×???APP. ?é?????? NVIC_SystemReset(); } } [/mw_shl_code]

void iap_load_app(u32 appxaddr)
{
if(((*(vu32*)appxaddr)&0x2FFE0000)==0x20000000) //?ì?é???????·??·???·¨.
{
jump2app=(iapfun)*(vu32*)(appxaddr+4);
  //°?jump2app×?????????????
MSR_MSP(*(vu32*)appxaddr); //??????APP????????(???§?ú????????????×???????·????????·)
jump2app(); //??×???APP. ?é??????
}
}
APP程序开头如下：
int main(void)
{
SCB->VTOR = FLASH_BASE | 0x20000;

/* LED ?????????? */

LED_GPIO_Configuration();
// RelayGPIO_Init();
buzze();
GPIO_SetBits(GPIOB,GPIO_Pin_0);
GPIO_SetBits(GPIOB,GPIO_Pin_8);
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOB,GPIO_Pin_8);

/* ·?·¨2????????????????IO */
while (1)
{
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOC,GPIO_Pin_3);
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOC,GPIO_Pin_4);
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOC,GPIO_Pin_5);
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOC,GPIO_Pin_6);
Delay(0x0FFFFF);
GPIO_ResetBits(GPIOC,GPIO_Pin_7);
GPIO_SetBits(GPIOC,GPIO_Pin_3);
Delay(0x0FFFFF);
GPIO_SetBits(GPIOC,GPIO_Pin_4);
Delay(0x0FFFFF);
GPIO_SetBits(GPIOC,GPIO_Pin_5);
Delay(0x0FFFFF);
GPIO_SetBits(GPIOC,GPIO_Pin_6);
Delay(0x0FFFFF);
GPIO_SetBits(GPIOC,GPIO_Pin_7);
}

}
