linux下查看mmc分区信息

转载地址：http://ju.outofmemory.cn/entry/373310

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
 mmc

查看对应的分区信息：

cat /proc/partitions |grep 179
        0    7634944 mmcblk0
        1       4096 mmcblk0p1
        2      65536 mmcblk0p2
        3     524288 mmcblk0p3
        4       8192 mmcblk0p4
        5      32768 mmcblk0p5
        6      32768 mmcblk0p6
        7       8192 mmcblk0p7
        8       8192 mmcblk0p8
        9      32768 mmcblk0p9
       10      32768 mmcblk0p10
       11      32768 mmcblk0p11
       12    1310720 mmcblk0p12
       13    5419008 mmcblk0p13
       96        512 mmcblk0rpmb
       64       4096 mmcblk0boot1
       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  7 Jul 29 09:08 /dev/block/179:10 -> ../misc
lrwxrwxrwx 1 root root  7 Jul 29 09:08 /dev/block/179:11 -> ../boot
lrwxrwxrwx 1 root root  9 Jul 29 09:08 /dev/block/179:12 -> ../system
lrwxrwxrwx 1 root root  7 Jul 29 09:08 /dev/block/179:13 -> ../data
lrwxrwxrwx 1 root root 11 Jul 29 09:08 /dev/block/179:2 -> ../reserved
lrwxrwxrwx 1 root root  8 Jul 29 09:08 /dev/block/179:3 -> ../cache
lrwxrwxrwx 1 root root 15 Jul 29 09:08 /dev/block/179:32 -> ../mmcblk0boot0
lrwxrwxrwx 1 root root  6 Jul 29 09:08 /dev/block/179:4 -> ../env
lrwxrwxrwx 1 root root  7 Jul 29 09:08 /dev/block/179:5 -> ../logo
lrwxrwxrwx 1 root root 11 Jul 29 09:08 /dev/block/179:6 -> ../recovery
lrwxrwxrwx 1 root root 15 Jul 29 09:08 /dev/block/179:64 -> ../mmcblk0boot1
lrwxrwxrwx 1 root root  6 Jul 29 09:08 /dev/block/179:7 -> ../rsv
lrwxrwxrwx 1 root root  6 Jul 29 09:08 /dev/block/179:8 -> ../tee
lrwxrwxrwx 1 root root  8 Jul 29 09:08 /dev/block/179:9 -> ../crypt
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
