在x86电脑上使用fdisk就能查看所有硬盘的信息，n1为android mmc分区，通过u盘引导linux后查看分区方法如下
查看mmc存储的设置号：
cat /proc/devices |grep mmc
179 mmc查看对应的分区信息：
cat /proc/partitions |grep 179
179 0 7634944 mmcblk0
179 1 4096 mmcblk0p1
179 2 65536 mmcblk0p2
179 3 524288 mmcblk0p3
179 4 8192 mmcblk0p4
179 5 32768 mmcblk0p5
179 6 32768 mmcblk0p6
179 7 8192 mmcblk0p7
179 8 8192 mmcblk0p8
179 9 32768 mmcblk0p9
179 10 32768 mmcblk0p10
179 11 32768 mmcblk0p11
179 12 1310720 mmcblk0p12
179 13 5419008 mmcblk0p13
179 96 512 mmcblk0rpmb
179 64 4096 mmcblk0boot1
179 32 4096 mmcblk0boot0查看分区映射：
ls -al /dev/block/179*
lrwxrwxrwx 1 root root 10 Jul 29 09:08 /dev/block/179:0 -> ../mmcblk0
lrwxrwxrwx 1 root root 13 Jul 29 09:08 /dev/block/179:1 -> ../bootloader

lrwxrwxrwx 1 root root 14 Jul 29 09:08 /dev/block/179:96 -> ../mmcblk0rpmb然后可以使用fdisk查看特定分区信息了，如查看mmcblk0p13：
fdisk -l /dev/data标签：none
