IAR环境stm32f030 IAP升级：
IAP核心代码：
#if(FLASH_PAGE_SIZE == 0X400U)
#define FLASH_SIZE (256 * FLASH_PAGE_SIZE)
#define BOOT_AREA_SIZE (12 * FLASH_PAGE_SIZE)
#define TAG_AREA_SIZE (2 * FLASH_PAGE_SIZE)
#define APP1_AREA_SIZE ((FLASH_SIZE -BOOT_AREA_SIZE-TAG_AREA_SIZE)/2) // must mod == 0
#define APP2_AREA_SIZE APP1_AREA_SIZE
#endif
#if(FLASH_PAGE_SIZE == 0x800U)
#define FLASH_SIZE (128 * FLASH_PAGE_SIZE)
#define BOOT_AREA_SIZE (7 * FLASH_PAGE_SIZE)
#define TAG_AREA_SIZE (1 * FLASH_PAGE_SIZE)
#define APP1_AREA_SIZE ((FLASH_SIZE -BOOT_AREA_SIZE-TAG_AREA_SIZE)/2) // must mod == 0
#define APP2_AREA_SIZE APP1_AREA_SIZE
#endif
#define BASE_ADDRESS 0x08000000
#define TAG_ADDRESS (BOOT_AREA_SIZE + APP1_AREA_SIZE + APP2_AREA_SIZE + BASE_ADDRESS)
#define APP1_IMG_BEG_ADDRESS (BOOT_AREA_SIZE + BASE_ADDRESS)
#define APP2_IMG_BEG_ADDRESS (BOOT_AREA_SIZE + APP1_AREA_SIZE + BASE_ADDRESS)
typedef void ( *jump ) ( void );
void Restart ( void )
{
jump reboot;
__set_MSP ( * ( volatile uint32_t * ) 0x08000000 );
reboot = ( jump ) * ( volatile uint32_t * ) 0x08000004;
reboot();
}
void AppJump ( void )
{
jump appjump;
__set_MSP ( * ( volatile uint32_t* ) APP1_IMG_BEG_ADDRESS );
appjump = ( jump ) * ( volatile uint32_t * ) ( APP1_IMG_BEG_ADDRESS + 4 );
appjump();
}
工程配置按照正常工程配置即可；
APP端核心代码：
#if(FLASH_PAGE_SIZE == 0X400U)
#define FLASH_SIZE (256 * FLASH_PAGE_SIZE) // only support even page
#define BOOT_AREA_SIZE (12 * FLASH_PAGE_SIZE) // only support even page
#define TAG_AREA_SIZE (2 * FLASH_PAGE_SIZE) // only support even page
#define APP1_AREA_SIZE ((FLASH_SIZE -BOOT_AREA_SIZE-TAG_AREA_SIZE)/2) // must mod == 0
#define APP2_AREA_SIZE APP1_AREA_SIZE
#endif
#if(FLASH_PAGE_SIZE == 0x800U)
#define FLASH_SIZE (128 * FLASH_PAGE_SIZE)
#define BOOT_AREA_SIZE (7 * FLASH_PAGE_SIZE)
#define TAG_AREA_SIZE (1 * FLASH_PAGE_SIZE)
#define APP1_AREA_SIZE ((FLASH_SIZE -BOOT_AREA_SIZE-TAG_AREA_SIZE)/2) // must mod == 0
#define APP2_AREA_SIZE APP1_AREA_SIZE
#endif
#define BASE_ADDRESS 0x08000000
#define TAG_ADDRESS (BOOT_AREA_SIZE + APP1_AREA_SIZE + APP2_AREA_SIZE + BASE_ADDRESS)
#define APP1_IMG_BEG_ADDRESS (BOOT_AREA_SIZE + BASE_ADDRESS)
#define APP2_IMG_BEG_ADDRESS (BOOT_AREA_SIZE + APP1_AREA_SIZE + BASE_ADDRESS)
#if (defined ( __CC_ARM ))
volatile uint32_t VectorTable[48] __attribute__ ( ( at ( 0x20000000 ) ) );
#elif (defined (__ICCARM__))
#pragma location = 0x20000000
__no_init volatile uint32_t VectorTable[48];
#elif defined ( __GNUC__ )
volatile uint32_t VectorTable[48] __attribute__ ( ( section ( ".RAMVectorTable" ) ) );
#elif defined ( __TASKING__ )
volatile uint32_t VectorTable[48] __at ( 0x20000000 );
#endif
void VectorTableRemap ( void )
{
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 APP_IMAG_LOCATION) to the base address of the SRAM at 0x20000000. */
for ( i = 0; i < 48; i++ )
{
VectorTable[i] = * ( volatile uint32_t* ) ( APP1_IMG_BEG_ADDRESS + ( i << 2 ) );
// VectorTable[i] = * ( volatile uint32_t* ) ( 0x08000000 + ( i << 2 ) );
}
/* Enable the SYSCFG peripheral clock*/
__HAL_RCC_SYSCFG_CLK_ENABLE();
/* Remap SRAM at 0x00000000 */
__HAL_SYSCFG_REMAPMEMORY_SRAM();
}
将此函数放到main函数最开头即可，然后将中断向量表起始地址改为APP1_IMG_BEG_ADDRESS ，ram起始地址改为0x200000C0，如下图所示：
至此，IAP功能便配置成功，详细原理可以参考如下链接：
