STM32F103急速IAR做OTA升级

article 2025/3/4 8:50:18

1-BOOT完成仅仅点灯

//HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);//HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin,GPIO_PIN_SET);  HAL_GPIO_WritePin(LED_GPIO_Port, LED_Pin,GPIO_PIN_RESET);  while (1)

仿真一切正常

2-拷贝一模一样的工程

完成BLINK

  while (1)  {
  
      /* USER CODE END WHILE */HAL_Delay(100);HAL_GPIO_TogglePin(LED_GPIO_Port, LED_Pin);    /* USER CODE BEGIN 3 */  }

仿真一切正常

使用J-LINK直接烧写正常

现在完成从BOOT跳转到APP

烧写是bin+bin中间填充FF 合并脚本如下

BOOT程序的跳转函数

APP程序的设置因为BOOT的bin是4K 设置稍微大一些就8K用作BOOT后面全部是APP

修改连接文件:

修改C文件:偏移量#define VECT_TAB_OFFSET 0x2000


/*简单合并bin的脚步 苛求名字是boot.bin+app.bin合成一个all.bin 并且app.bin的起始位置也是死的 中间填充0XFF*/

void jump_application( void )
{
     JumpAddress = *(__IO uint32_t*) (APPLICATION_ADDRESS + 4);
    if ( (JumpAddress & 0xFF000000 ) == 0x08000000) //stack use flash
