CubeMX生成的代码第一次可以成功烧写，之后断电再烧写就不行了

错误提示如图所示，主芯片是stm32h743vgt，工具keil5，烧写方式SWD。

另外，CubeMX的debug mode配置如下：

附上初始化代码：

/ MPU Configuration--------------------------------------------------------/ MPU_Config(); / Enable I-Cache---------------------------------------------------------/ SCB_EnableICache();

/ Enable D-Cache---------------------------------------------------------/ SCB_EnableDCache();

/ MCU Configuration--------------------------------------------------------/

/ Reset of all peripherals, Initializes the Flash interface and the Systick. / HAL_Init();

/ USER CODE BEGIN Init /

/ USER CODE END Init /

/ Configure the system clock / SystemClock_Config();
