vold fstab

Some time ago, I made a few brief analyses on the Android SDCard unmount process. Since it was just a conversation on paper and there was no actual follow-up, there may be some misleading or minor errors. Today, I reorganized my mind and analyzed the mount process again.Outline• How does the android system boot and listen to the mount service?• Which directory of the default mount point is in the Android system?• Vold.

, only the 128-bit key is reencrypted and stored. (Changing user PIN/password/mode will not cause user data to be re-encrypted ). Note that the managed devices may be subject to PIN, mode, or password restrictions. Encryption is managed by init and vold. Init calls vold and vold sets the attribute in init to trigger the event. Other parts of the system also work

The SD card cannot be automatically mounted during the migration of Android to the platform. Check the related information. In android2.3, the vold program is responsible for checking the sysfs File System of the kernel. After the SD card is inserted, it is automatically mounted. There is a vold under the file system directory/system/etc. fstab file, which is an

. ========================================================== ========================================================== ==================================== For Android system sdcard development, the main work is as follows: (1) After kernel driver development, the sdcard system will display relevant information each time it is inserted and pulled out, and the sdcard can be manually mounted. (2) Android sdcard mounting is mainly completed by vold. Th

This paper illustrates the method of Android2.3 to realize the automatic mounting of SD card and U disk. Share to everyone for your reference, specific as follows: The SD card is always not mounted automatically when porting the android2.3 on the s3c6410 platform. Check the relevant information, know in android2.3 is the Vold program is responsible for checking the kernel of the Sysfs file system, found that there is an SD card inserted, automatic mo

The hardware engineer built a USB hub line on the basis of sugar-Standard Later, he made the USB interface into the A20 sugar-cubieboard 2, so when the original IMG was burned in, the U port did not respond, only one port can use the mouse. According to the information, the android system automatically mounts the USB flash disk, which is related to a file named vold. fstab. So find./-name "

The previous http://www.bkjia.com/kf/201203/124631.html talked about sending the uevent command to the onEvent of NetlinkHandler through NetlinkManager. The Code is as follows:Void NetlinkHandler: onEvent (NetlinkEvent * evt ){VolumeManager * vm = VolumeManager: Instance ();Const char * subsys = evt-> getSubsystem (); If (! Subsys ){SLOGW ("No subsystem found in netlink event ");Return;}SLOGD ("NetlinkHandler: OnEvent subsys values is % s", subsys );If (! Strcmp (subsys, "block ")){SLOGD ("Netli

I always thought that the automatic mounting of Android SD card is implemented in Vold, and its configuration file is easily found on the Internet which is system/etc/vold. in fstab, the configuration file is Mount, which is generally as follows: Dev_mount sdcard/mnt/sdcard 3/devices/platform/sc65-sdhci.0/mmc_host/mmc0/mmc0: 0001/block/mmcblk0 nonremovable, en

Recently, I am working on a mobile phone project. Every time I use a ZIP package for upgrade, I need to copy it to the SD card before upgrading it from the SD card. The SD card is hard to find. It is troublesome to unload it from another mobile phone every time and install it after upgrade. Since internal storage is supported, why cannot I upgrade it from the internal storage? It seems that Huawei and other mobile phones support this function. Go to recovery and check that built-in SD is not mou

not very familiar with the analysis in some places, but as a driver user and adapter, as the university teacher said, I don't have to know how to come, just know how to use it. Therefore, after analyzing the USB Mount-related kernel drivers, it is obvious that the most important thing is the parameter configuration process in the mass_storage_function_init function. determine the number of Luns and their respective attributes. Then the initialization can be completed in the kernel structure, an
