STM32F411CEU6 使用SDIO 1bit 挂载SD NAND文件系统成功，列出一个细节问题

发布于 2025-01-17 21:32:17 浏览：36 订阅该版

搞了两天 STM32F411CEU6上挂载sd nand，终于成功了。

板子上使用的是sdio 1bit方式进行驱动，参考了很多博客教程，都遇到了不能挂载的问题。
提示如下

```

后来，猜测rtthread sdio驱动中有可能不是1bit通信，在drv_sdio.c中查找，最终确认了问题。
```
#ifndef SDIO_USING_1_BIT
    host->flags = MMCSD_BUSWIDTH_4 | MMCSD_MUTBLKWRITE | MMCSD_SUP_SDIO_IRQ;
#else
    host->flags = MMCSD_MUTBLKWRITE | MMCSD_SUP_SDIO_IRQ;
#endif
```
这里如果没有定义  `#define SDIO_USING_1_BIT` 那么默认使用4bit通信。

因此在board.h中必须启用sdio1bit
```
/** if you want to use sdio you can use the following instructions.
 *
 * STEP 1, open sdio driver framework support in the RT-Thread Settings file
 *
 * STEP 2, define macro related to the sdio
 *                 such as    BSP_USING_SDIO
 *
 * STEP 3, copy your sdio init function from stm32xxxx_hal_msp.c generated by stm32cubemx to the end of board.c file
 *                 such as     void HAL_SD_MspInit(SD_HandleTypeDef* hsd)
 *
 * STEP 4, modify your stm32xxxx_hal_config.h file to support sdio peripherals. define macro related to the peripherals
 *                 such as     #define HAL_SD_MODULE_ENABLED
 *
 * STEP 5, config your device file system or another applications
 *
 */
#define SDIO_USING_1_BIT
#define BSP_USING_SDIO
```

成功后的打印信息如下
```
