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：
1 2 | cat /proc/devices |grep mmc179 mmc |
查看对应的分区信息：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | 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：

然后可以使用fdisk查看特定分区信息了，如查看mmcblk0p13：
1 | fdisk -l /dev/data |
标签：none
