aio3568系统下，无法挂载emmc分区

darennet

1）系统启动后，通过串口登录到系统里面，想通过mount来挂载指定分区，发现会报以下错误：

1. root@rk3568-buildroot:/userdata# mount /dev/mmcblk0p2 mnt/
   
2. [ 1319.267226] FAT-fs (mmcblk0p2): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
   
3. NTFS signature is missing.
   
4. Failed to mount '/dev/mmcblk0p2': Invalid argument
   
5. The device '/dev/mmcblk0p2' doesn't seem to have a valid NTFS.
   
6. Maybe the wrong device is used? Or the whole disk instead of a
   
7. partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

2）通过fdisk -l 查看分区信息：

1. # fdisk -l
   
2. Disk /dev/ram0: 4 MiB, 4194304 bytes, 8192 sectors

我的问题是：
1、emmc分区类型显示为unknown是否正常？如果正常，这样做目的是什么？
2、如何才能成功挂载emmc的分区到指定目录？

谢谢！
