STM32F0 IAP (使用stm32CubeMX)

BootLoader：

main里调用函数跳转到APP地址0x8003000

typedef  void (*pFunction)(void);

#define ApplicationAddress    0x8003000

void UserAppStart(void)

{

  if (((*(__IO uint32_t*)ApplicationAddress) & 0x2FFE0000 ) == 0x20000000)

    { 

      /* Jump to user application */

      JumpAddress = *(__IO uint32_t*) (ApplicationAddress + 4);

      Jump_To_Application = (pFunction) JumpAddress;

      /* Initialize user application's Stack Pointer */

      __set_MSP(*(__IO uint32_t*) ApplicationAddress);

      Jump_To_Application();

    }

}

APP：

main 函数添加

#define APPLICATION_ADDRESS     ((uint32_t)0x08003000)

#if   (defined ( __CC_ARM ))

  __IO uint32_t VectorTable[48] __attribute__((at(0x20000000)));

#elif (defined (__ICCARM__))

#pragma location = 0x20000000

  __no_init __IO uint32_t VectorTable[48];

#elif defined   (  __GNUC__  )

  __IO uint32_t VectorTable[48] __attribute__((section(".RAMVectorTable")));

#elif defined ( __TASKING__ )

  __IO uint32_t VectorTable[48] __at(0x20000000);

#endif

  /* USER CODE BEGIN 1 */

uint32_t i = 0;

  /* Relocate by software the vector table to the internal SRAM at 0x20000000 ***/  

  /* Copy the vector table from the Flash (mapped at the base of the application

     load address 0x08003000) to the base address of the SRAM at 0x20000000. */

  for(i = 0; i < 48; i++)

  {

    VectorTable[i] = *(__IO uint32_t*)(APPLICATION_ADDRESS + (i<<2));

  }

// Enable the SYSCFG peripheral clock

  __HAL_RCC_SYSCFG_CLK_ENABLE();

  // Remap SRAM at 0x00000000 

  __HAL_SYSCFG_REMAPMEMORY_SRAM();

在Keil下设置IROM1：start 0x8003000 IRAM1：Start 0x200000C0

stm32f0 没有中断偏移寄存器，所以将中断向量表读取到RAM中，然后重映射到RAM地址.
