急求高手解答-内核启动后的问题

问题背景：我是从SD卡启动的内核

内核可以启动具体现象如下：
.....................................

Enter 'help' for a list of built-in commands.

/ # ls
bin devel lost+found sbin usr
boot etc proc sys var
dev lib root tmp
/ # fdisk -l
/ #

问题：为什么内启动后输入命令fdisk -l 没有任何设备呢，实际是有的啊mmcblk0(红色字体处)，这个设备是eMMC。还有就是我的SD卡也是分4个区的啊，至少SD的应该显示吧。
该如何解决呢？
