同时挂载 SD卡与FLASH 在shell中怎样区分

  if (dfs_mount("flash0", "/", "elm", 0, 0) == 0)
    {
        rt_kprintf("File flash System initialized!
");
    }
    else
        rt_kprintf("File flash System initialzation failed!
");		
		
    if (dfs_mount("sd0", "/dev", "elm", 0, 0) == 0)
    {
        rt_kprintf("File sd System initialized!
");
    }
    else
        rt_kprintf("File sd System initialzation failed!
");

ls()命令直接访问根目录

This guy hasn't written anything yet

ls("/")
ls("/dev")

另外，为什么要放"/dev"目录去？"/dev"目录不是给一般文件系统使用的。你可以
mkdir("/flash");
mount("sd0", "/flash"....);

    if (dfs_mount("flash0", "/", "elm", 0, 0) == 0)
    {
        rt_kprintf("
 mount flash ok!
");
    }
    else
        rt_kprintf(" mount flash error!
");

		mkdir("/sd",0);
		
    if (dfs_mount("sd0", "/sd", "elm", 0, 0) == 0)
    {
        rt_kprintf(" mount sd ok!
");
    }
    else
        rt_kprintf(" mount sd error!
");
