stm32f030代码升级总结

bootloader设置：

static void check_boot_mode(void)

{

uint32_t JumpAddress;

void(*Jump_To_Application)(void);

if (((*((__IO uint32_t*)(APP_SEGA_START_ADDRESS+8))) & 0x2FFE0000 ) == 0x20000000)

{

JumpAddress = *(__IO uint32_t*) (APP_SEGA_START_ADDRESS + 12);

Jump_To_Application = (void *)JumpAddress;

__set_MSP(*((__IO uint32_t*) (APP_SEGA_START_ADDRESS+8)));

Jump_To_Application();

}

}

application设置：

const uint8_t eh[8] __attribute__((at(0x08004000)));这个是使应用代码加载首地址向后推移8字节；

下图是应用代码加载地址和内存设置：

下面是中断向量表映射配置：

#define APPLICATION_ADDRESS (uint32_t)0x08004008

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

for(i = 0; i < 48; i++)

{

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

}
