使用fal把外置w25q128 进行分区  原来的设想是分四个区
```c
#define FAL_PART_TABLE                                                               \
{                                                                                    \
    {FAL_PART_MAGIC_WORD,        "download",          NOR_FLASH_DEV_NAME,          FLASH_DOWNLOAD_ADDR,  FLASH_DOWNLOAD_SIZE, 0}, \
    {FAL_PART_MAGIC_WORD,        "factory",           NOR_FLASH_DEV_NAME,          FLASH_FACTORY_ADDR,  FLASH_FACTORY_SIZE, 0}, \
    {FAL_PART_MAGIC_WORD,        "romfs",             NOR_FLASH_DEV_NAME,          FLASH_ROMFS_ADDR,  FLASH_ROMFS_SIZE, 0}, \
    {FAL_PART_MAGIC_WORD,        "filesystem",        NOR_FLASH_DEV_NAME,          FLASH_FATS_ADDR,  FLASH_FATS_SIZE, 0}, \
}
```
其中romfs分区用来挂载 romfs文件系统 创建 
```c
const struct romfs_dirent _root_dirent[] =
{
    {ROMFS_DIRENT_DIR, "easyflash", RT_NULL, 0},
    {ROMFS_DIRENT_DIR, "download", RT_NULL, 0},
    {ROMFS_DIRENT_DIR, "user", RT_NULL, 0},
    {ROMFS_DIRENT_DIR, "factory", RT_NULL, 0},
};

const struct romfs_dirent romfs_root =
{
    ROMFS_DIRENT_DIR, "/", (rt_uint8_t *)_root_dirent, sizeof(_root_dirent) / sizeof(_root_dirent[0])
};
```

```c
    flash_dev = fal_blk_device_create(FS_ROMFS_NAME);
    if (flash_dev == NULL){
        LOG_D("Can't create a block device on '%s' partition.\n", FS_ROMFS_NAME);
        return -1;
    }
    //romfs分区           rom文件系统挂载到 /
    if (dfs_mount(FS_ROMFS_NAME, "/", "rom", 0, &(romfs_root)) != 0)
    {
        if(dfs_mkfs("rom", FS_ROMFS_NAME) != 0)
        {
            LOG_E("Failed to initialize romfs! ");
        }
        else {
            dfs_mount(FS_ROMFS_NAME, "/", "rom", 0, &(romfs_root));
        }
    }
```
四个文件夹 再将elm 挂载到/user 目录下
```c
    flash_dev = fal_blk_device_create(FS_FATS_NAME);
    if (flash_dev == NULL){
        LOG_D("Can't create a block device on '%s' partition.\n", FS_FATS_NAME);
        return -1;
    }
    //filesystem分区   elm文件系统挂载到/user
    if (dfs_mount(FS_FATS_NAME, "/user", "elm", 0, 0) != 0)
    {
        if(dfs_mkfs("elm", FS_FATS_NAME) != 0)
        {
            LOG_E("Failed to initialize filesystem! ");
        }
        else {

dfs_mount(FS_FATS_NAME, "/user", "elm", 0, 0);
        }
    }
```
发现 我使用tftp 的时候
```
msh /user/webnet>tftp -s
tftp server is runmsh /user/webnet>server write file err! disconnect client
server write file err! disconnect client
server write file err! disconnect client
server write file err! disconnect client

msh /user/webnet>
msh /user/webnet>
msh /user/webnet>
msh /user/webnet>
msh /user/webnet>server write file err! disconnect client
server write file err! disconnect client
server write file err! disconnect client
server write file err! disconnect client
server write file err! disconnect client
```

我就好奇了 这为啥不行
然后 我就直接把elm文件系统直接挂载在根目录下
```c
        flash_dev = fal_blk_device_create(FS_FATS_NAME);
        if (flash_dev == NULL){
            LOG_D("Can't create a block device on '%s' partition.\n", FS_FATS_NAME);
            return -1;
        }
        if (dfs_mount(FS_FATS_NAME, "/", "elm", 0, 0) != 0)
        {
            if(dfs_mkfs("elm", FS_FATS_NAME) != 0)
            {
                LOG_E("Failed to initialize filesystem! ");
            }
            else {

dfs_mount(FS_FATS_NAME, "/", "elm", 0, 0);
            }
        }
```
tftp 就可以了 。。。。。

搞不懂 那要这个romfs干啥？
