1、硬件使能
根据正点原子的原理图配置进行SPIflash的配置如下:
2、RT-Thread Setting设置
3、board.h文件设置
增加#define BSP_USING_SPI5宏定义
4、挂载SPI flash
新建drivers\drv_spiflash.c文件,内容如下
#include "board.h"
#include <rtthread.h>
#include <rtdevice.h>
#include "drv_spi.h"
#include "drv_config.h"
#include <string.h>
#include "spi_flash_sfud.h"
static int rt_hw_spi_flash_init(void)
{
__HAL_RCC_GPIOF_CLK_ENABLE();
rt_hw_spi_device_attach("spi5", "spi50", GPIOF, GPIO_PIN_6);
if (RT_NULL == rt_sfud_flash_probe("W25Q256", "spi50"))
{
return -RT_ERROR;
};
return RT_EOK;
}
/* 导出到自动初始化 */
INIT_COMPONENT_EXPORT(rt_hw_spi_flash_init);
编译下载,串口输出如下
5、文件系统挂载
在main.c文件中实现如下函数进行flash下文件系统的挂载,主函数调用该函数。
static int dfs_mount_init(void)
{
if(dfs_mount("W25Q256", "/", "elm", 0, 0) == 0)
{
rt_kprintf("dfs mount success\r\n");
return RT_EOK;
}
else
{
rt_kprintf("spi file system initialized faile\r\n");
if(dfs_mkfs("elm", "W25Q256") == 0)
{
rt_kprintf("W25QXX file system initialized\r\n");
if(dfs_mount("W25Q256", "/", "elm", 0, 0) == 0)
{
rt_kprintf("dfs mount success\r\n");
return RT_EOK;
}
else
{
rt_kprintf("dfs mount success\r\n");
return -RT_ERROR;
}
}
else
{
rt_kprintf("dfs mount success\r\n");
return -RT_ERROR;
}
}
}
下载验证,串口输出如下
6、挂载目录的修改
上述挂载过程将flash直接挂载到了根目录,若存在多个挂载设备我们无法进行区分。所以通过下操作来实现根目录下不同目录的挂载。
修改rt-thread\components\def\filesystems\romfs\romfs.c文件如下,我们在根目录下增加了sdcard和w25qxx两个目录。
#include <rtthread.h>
#include <dfs_romfs.h>
#include "dfs.h"
static const struct romfs_dirent _romfs_root[] =
{
{ROMFS_DIRENT_DIR, "sdcard", RT_NULL, 0},
{ROMFS_DIRENT_DIR, "w25qxx", RT_NULL, 0}
};
const struct romfs_dirent romfs_root =
{
ROMFS_DIRENT_DIR, "/", (rt_uint8_t *)_romfs_root, sizeof(_romfs_root)/sizeof(_romfs_root[0])
};
int mnt_init(void)
{
if(dfs_mount (RT_NULL,"/","rom",0,&(romfs_root)) == 0)
{
rt_kprintf("ROM file system initializated;\n");
}
else
{
rt_kprintf("ROM file system initializate failed;\n");
}
return 0;
}
INIT_ENV_EXPORT(mnt_init);
同步对main.c中的dfs_mount_init进行修改
static int dfs_mount_init(void)
{
if(dfs_mount("W25Q256", "/w25qxx", "elm", 0, 0) == 0)
{
rt_kprintf("dfs mount success\r\n");
return RT_EOK;
}
else
{
rt_kprintf("spi file system initialized faile\r\n");
if(dfs_mkfs("elm", "W25Q256") == 0)
{
rt_kprintf("W25QXX file system initialized\r\n");
if(dfs_mount("W25Q256", "/w25qxx", "elm", 0, 0) == 0)
{
rt_kprintf("dfs mount success\r\n");
return RT_EOK;
}
else
{
rt_kprintf("dfs mount success\r\n");
return -RT_ERROR;
}
}
else
{
rt_kprintf("dfs mount success\r\n");
return -RT_ERROR;
}
}
}
下载验证,串口如下
