aio3568系统下,无法挂载emmc分区

问题描述及复现步骤:
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?
复制代码
2)通过fdisk -l 查看分区信息:
  1. # fdisk -l
  2. Disk /dev/ram0: 4 MiB, 4194304 bytes, 8192 sectors
  3. Units: sectors of 1 * 512 = 512 bytes
  4. Sector size (logical/physical): 512 bytes / 4096 bytes
  5. I/O size (minimum/optimal): 4096 bytes / 4096 bytes


  6. Disk /dev/mtdblock0: 32 MiB, 33554432 bytes, 65536 sectors
  7. Units: sectors of 1 * 512 = 512 bytes
  8. Sector size (logical/physical): 512 bytes / 512 bytes
  9. I/O size (minimum/optimal): 512 bytes / 512 bytes


  10. Disk /dev/mmcblk0: 29.12 GiB, 31268536320 bytes, 61071360 sectors
  11. Units: sectors of 1 * 512 = 512 bytes
  12. Sector size (logical/physical): 512 bytes / 512 bytes
  13. I/O size (minimum/optimal): 512 bytes / 512 bytes
  14. Disklabel type: gpt
  15. Disk identifier: 3A030000-0000-4E62-8000-74DD00004243

  16. Device           Start      End  Sectors  Size Type
  17. /dev/mmcblk0p1   16384    24575     8192    4M unknown
  18. /dev/mmcblk0p2   24576    32767     8192    4M unknown
  19. /dev/mmcblk0p3   32768   294911   262144  128M unknown
  20. /dev/mmcblk0p4  294912   425983   131072   64M unknown
  21. /dev/mmcblk0p5  425984   491519    65536   32M unknown
  22. /dev/mmcblk0p6  491520   753663   262144  128M unknown
  23. /dev/mmcblk0p7  753664  3429375  2675712  1.3G unknown
  24. /dev/mmcblk0p8 3429376 61071295 57641920 27.5G unknown
复制代码

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!
