stm32f407 SDIO时钟问题

问题遇到的现象和发生背景

我在写SD卡得驱动程序

问题相关代码，请勿粘贴截图

static void SystemClock_Config(void)
{
  RCC_ClkInitTypeDef RCC_ClkInitStruct;
  RCC_OscInitTypeDef RCC_OscInitStruct;

  /* Enable Power Control clock */
  __HAL_RCC_PWR_CLK_ENABLE();

  /* The voltage scaling allows optimizing the power consumption when the device is 
     clocked below the maximum system frequency, to update the voltage scaling value 
     regarding system frequency refer to product datasheet.  */
  __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1);

  /* Enable HSE Oscillator and activate PLL with HSE as source */
  RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
  RCC_OscInitStruct.HSEState = RCC_HSE_ON;
  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
  RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
  RCC_OscInitStruct.PLL.PLLM = 8;
  RCC_OscInitStruct.PLL.PLLN = 336;
  RCC_OscInitStruct.PLL.PLLP = RCC_PLLP_DIV2;
  RCC_OscInitStruct.PLL.PLLQ = 7;
  
  if(HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
  {
    BSP_Error_Handler(__FILE__, __LINE__);
  }
  
  /* Select PLL as system clock source and configure the HCLK, PCLK1 and PCLK2 
     clocks dividers */
  RCC_ClkInitStruct.ClockType = (RCC_CLOCKTYPE_SYSCLK | RCC_CLOCKTYPE_HCLK | RCC_CLOCKTYPE_PCLK1 | RCC_CLOCKTYPE_PCLK2);
  RCC_ClkInitStruct.SYSCLKSource = RCC_SYSCLKSOURCE_PLLCLK;
  RCC_ClkInitStruct.AHBCLKDivider = RCC_SYSCLK_DIV1;
  RCC_ClkInitStruct.APB1CLKDivider = RCC_HCLK_DIV4;  
  RCC_ClkInitStruct.APB2CLKDivider = RCC_HCLK_DIV2;  
  if(HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_3) != HAL_OK)
  {
    BSP_Error_Handler(__FILE__, __LINE__);
  }
}


//读SD卡
//buf:读数据缓存区
//sector:扇区地址
//cnt:扇区个数    
//返回值:错误状态;0,正常;其他,错误代码;
uint8_t SD_ReadDisk(uint8_t* buf,u32 sector,u32 cnt)
{
    uint8_t sta=HAL_OK;
    u32 timeout=SD_TIMEOUT;
    long long lsector=sector;
    INTX_DISABLE();//关闭总中断(POLLING模式,严禁中断打断SDIO读写操作!!!)
    sta=HAL_SD_ReadBlocks(&SDCARD_Handler, (uint8_t*)buf,lsector,cnt,SD_TIMEOUT);//多个sector的读操作
    
    //等待SD卡读完

    while(SD_GetCardState()!=SD_TRANSFER_OK)
        {
        if(timeout-- == 0)
        {    
            sta=SD_TRANSFER_BUSY;
        }
    }
    INTX_ENABLE();//开启总中断
    return sta;
}  

运行结果及报错内容

RCC_OscInitStruct.PLL.PLLQ = 7;

RCC_OscInitStruct.PLL.PLLQ = 4;

PLLQ 配置为4，读SD卡就会报错

我的解答思路和尝试过的方法

我看时钟树 PLLQ 和SDIO得外设没有关系啊

我想要达到的结果
