请教cubemx 配置的mpu问题

使用mx 配置了mpu。单步跑当跑到 MPU_Config();后进入此处报错。  请问是哪里配置错误了吗？void MemManage_Handler(void)
{
  /* USER CODE BEGIN MemoryManagement_IRQn 0 */

  /* USER CODE END MemoryManagement_IRQn 0 */
  while (1)
  {
/* USER CODE BEGIN W1_MemoryManagement_IRQn 0 */
/* USER CODE END W1_MemoryManagement_IRQn 0 */
  }
}

下边是mpu的内容
void MPU_Config(void)
{
  MPU_Region_InitTypeDef MPU_InitStruct = {0};

  /* Disables the MPU */
  HAL_MPU_Disable();
  /** Initializes and configures the Region and the memory to be protected
