如下图，在执行到HAL_FLASH_Program过程时，程序会跳入硬件错误，想了解可能是什么原因导致的，以及应该怎么解决

uint16_t MEM_If_Write_FS(uint8_t *src, uint8_t *dest, uint32_t Len)
{
  /* USER CODE BEGIN 3 */
  uint32_t i=0;
  printf("MEM_If_Write_FS->src:0x%x\r\n",src);
  printf("MEM_If_Write_FS->dest:0x%x\r\n",dest);
  printf("MEM_If_Write_FS->Len:%d\r\n",Len);
  for(i=0;i< Len; i += 4){
    /*Devicevoltagerangesupposedtobe[2.7Vto3.6V],theoperationwill
    bedonebybyte*/
    if(HAL_FLASH_Program(FLASH_TYPEPROGRAM_FLASHWORD,(uint32_t)(dest+i),*(uint32_t*)(src+i))==HAL_OK){
    /*Checkthewrittenvalue*/
      if(*(uint32_t*)(src+i)!=*(uint32_t*)(dest+i)){
      /*Flashcontentdoesn'tmatchSRAMcontent*/
        printf("Flash content doesn't match SRAM content\r\n");
        return(USBD_FAIL);
      }
    }else{
    /*ErroroccurredwhilewritingdatainFlashmemory*/
      printf("Error occurred while writing data in Flashmemory\r\n");
      return(USBD_FAIL);
    }
  }
  // UNUSED(src);
  // UNUSED(dest);
  // UNUSED(Len);
  printf("MEM_If_Write_FS OK\r\n");

  return (USBD_OK);
  /* USER CODE END 3 */
}
