板子：银杏STM32H750 icore4T,使用STM32H7 Art-pi的sdio驱动，但是在挂载过程中，一直在sd.c这个文件的一些函数里卡着。
这是hal_msp的sdmmc配置：
```
void HAL_SD_MspInit(SD_HandleTypeDef* hsd)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
  RCC_PeriphCLKInitTypeDef PeriphClkInitStruct = {0};
  if(hsd->Instance==SDMMC1)
  {
  /* USER CODE BEGIN SDMMC1_MspInit 0 */
  /* USER CODE END SDMMC1_MspInit 0 */
  /** Initializes the peripherals clock
  */
    PeriphClkInitStruct.PeriphClockSelection = RCC_PERIPHCLK_SDMMC;
    PeriphClkInitStruct.SdmmcClockSelection = RCC_SDMMCCLKSOURCE_PLL;
    if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInitStruct) != HAL_OK)
    {
     // Error_Handler();
    }

/* Peripheral clock enable */
    __HAL_RCC_SDMMC1_CLK_ENABLE();

__HAL_RCC_GPIOC_CLK_ENABLE();
    __HAL_RCC_GPIOD_CLK_ENABLE();
    /**SDMMC1 GPIO Configuration

    PD2     ------> SDMMC1_CMD
    PC9     ------> SDMMC1_D1
    PC8     ------> SDMMC1_D0
    */
    GPIO_InitStruct.Pin = GPIO_PIN_12|GPIO_PIN_11|GPIO_PIN_10|GPIO_PIN_9
                          |GPIO_PIN_8;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF12_SDIO1;
    HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);

GPIO_InitStruct.Pin = GPIO_PIN_2;
    GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
    GPIO_InitStruct.Pull = GPIO_NOPULL;
    GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
    GPIO_InitStruct.Alternate = GPIO_AF12_SDIO1;
    HAL_GPIO_Init(GPIOD, &GPIO_InitStruct);

/* SDMMC1 interrupt Init */
    HAL_NVIC_SetPriority(SDMMC1_IRQn, 0, 0);

}

这是System_clock的配置：

drv_sdio和sdio驱动文件均复制art-pi相同文件
现在挂载过程如下：能读出卡容量，但是之后就卡住了

调试后发现是在这里出的问题

然后进入mmcsd_send_app_cmd函数，在这里出问题

然后就send command循环套，返回err
实在不知道哪里出了问题，时钟配置是直接复制的，不知道有没有配置对，希望有大佬指点一下
