Je possède une Lenovo Tab 2 A7-20f.
Quand j'essaie cat /proc/emmc
:
partno: start_sect nr_sects partition_name
emmc_p1: 00000400 00000002 "ebr1"
emmc_p2: 00004800 00005000 "protect_f"
emmc_p3: 00009800 00005000 "protect_s"
emmc_p4: 0001ec00 00003000 "sec_ro"
emmc_p5: 0002e800 00300000 "android"
emmc_p6: 0032e800 0003f000 "cache"
emmc_p7: 0036d800 00b18000 "usrdata"
Et quand j'utilise cat /proc/partitions
:
major minor #blocks name
7 0 9570 loop0
253 0 524288 zram0
179 0 7613440 mmcblk0
179 1 1 mmcblk0p1
179 2 10240 mmcblk0p2
179 3 10240 mmcblk0p3
179 4 6144 mmcblk0p4
179 5 1572864 mmcblk0p5
179 6 129024 mmcblk0p6
179 7 5816320 mmcblk0p7
179 64 4096 mmcblk0boot1
179 32 4096 mmcblk0boot0
Je ne pense pas que ce soit la disposition typique des partitions Android. Une idée de la partition de récupération et de la partition de démarrage ? Ou comment le découvrir ?

Quand je cherche /proc/dumchar_info

Part\_Name:Partition name you should open;
Size:size of partition
StartAddr:Start Address of partition;
Type:Type of partition(MTD=1,EMMC=2)
MapTo:actual device you operate
Maintenant, comment puis-je trouver laquelle est la partition système et pourquoi Boot et Recovery sont une partition ?
