中兴Nubia Z5S 分区信息

在linux下连上数据线 输入命令  adb shell ls -l /dev/block/platform/msm_sdcc.1/by-name

可以得到如下信息:

这里就可以看到Nubia z5s的所有分区的标签(分区名) 以及对应的分区号

然后还可以看到各分区的大小, 使用adb shell cat /proc/partitions 命令:

major minor  #blocks  name

 179        0   15388672 mmcblk0
 179        1      65536 mmcblk0p1
 179        2        512 mmcblk0p2
 179        3         32 mmcblk0p3
 179        4         32 mmcblk0p4
 179        5        512 mmcblk0p5
 179        6        500 mmcblk0p6
 179        7      10240 mmcblk0p7
 179        8        500 mmcblk0p8
 179        9       1024 mmcblk0p9
 179       10       1536 mmcblk0p10
 179       11       1536 mmcblk0p11
 179       12       1024 mmcblk0p12
 179       13      10240 mmcblk0p13
 179       14    1258290 mmcblk0p14
 179       15    2621440 mmcblk0p15
 179       16      32768 mmcblk0p16
 179       17     512000 mmcblk0p17
 179       18     153600 mmcblk0p18
 179       19      10240 mmcblk0p19
 179       20       1536 mmcblk0p20
 179       21          1 mmcblk0p21
 179       22          8 mmcblk0p22
 179       23   10276838 mmcblk0p23
 179       32       4096 mmcblk0rpmb

blocks那一列即是分区的大小 单位为1024 字节 (emmc 扇区大小为512) 

比如 mmcblk0p7  boot分区的大小为 10240x1024字节= 10M 

recovery分区同样大小为10M 所以如果编译第三方recovery的大小超过这个数, 则刷入后会不正常!

需要注意的是 从上面可以看出来 有一个分区号32的分区

 179       32       4096 mmcblk0rpmb

这个不在分区列表里, 从内核启动的log 以及名称看 应该是rpm 分区的备份分区, 大小为4M
