我按着官网的sd卡文件系统教程来的  添加了如下三个函数
```c
void sd_mount(void *parameter)
{
    while (1)
    {
        rt_thread_mdelay(500);
        if(rt_device_find("sd0") != RT_NULL)
        {
            if (dfs_mount("sd0", "/C", "elm", 0, 0) == RT_EOK)
            {
                LOG_I("sd card mount to '/C'");
                break;
            }
            else
            {
                LOG_W("sd card mount to '/C' failed!");
            }
        }
    }
}

int stm32_sdcard_mount(void)
{
    rt_thread_t tid;

tid = rt_thread_create("sd_mount", sd_mount, RT_NULL,
                           1024, RT_THREAD_PRIORITY_MAX - 2, 20);
    if (tid != RT_NULL)
    {
        rt_thread_startup(tid);
    }
    else
    {
        LOG_E("create sd_mount thread err!");
    }
    return RT_EOK;
}
INIT_APP_EXPORT(stm32_sdcard_mount);

static int rt_hw_spi1_tfcard(void)
{
    __HAL_RCC_GPIOC_CLK_ENABLE();
    rt_hw_spi_device_attach("spi1", "spi10", GPIOC, GPIO_PIN_3);
     LOG_I("sd card  \r\n");
    return msd_init("sd0", "spi10");
}
INIT_DEVICE_EXPORT(rt_hw_spi1_tfcard);
```

然后串口显示挂载失败
