[0051] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0052] In one embodiment, Figure 1 As shown, a flash memory partition data processing method is provided. This embodiment takes the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0053] Step 102, when it is detected that there is a first incremental file in the target subdirectory of the mounted temporary file system, a timer is triggered to start timing from an initial preset value.

[0054] The temporary file system is a memory-based file system, i.e., a tmpfs file system; the first incremental file refers to the file whose target subdirectory is modified, i.e., the added file, which can be a user data file or a system configuration file. The initial preset value can be, but is not limited to, 10 seconds, 8 seconds, and 5 seconds.

[0055] Specifically, when the terminal is turned on, the system partition is automatically mounted to the directory and then the application is started. The user partition is mounted through the mount point. When the user partition is mounted successfully, the user program runs normally. When the terminal service detects that the file in the target subdirectory of the mounted temporary file system is modified, the timer is triggered to start, and the timer starts timing according to the initial preset value, and can be a countdown according to the initial preset value.

[0056] Step 104: When the timing value of the timer reaches the target preset value, the file carrying the first incremental file is compressed and the timer is reset to obtain a compressed file.

[0057] The target preset value refers to a preset value, which may be, but is not limited to, 0. For example, it may also be 1 or 2.

[0058] Specifically, when the timer counts according to the initial preset value and the timing value is the target preset value, all files under the target subdirectory are compressed, that is, the file set carrying the first incremental file is compressed to obtain a compressed file corresponding to the target subdirectory; and the timer is initialized, that is, reset to the initial preset value. For example, when the timer counts down according to the initial preset value 10 and the timing value is the target preset value 0, all files under the target subdirectory are compressed to obtain a compressed file.

[0059] Step 106: Generate a file write instruction.

[0060] The file write instruction is a command to write a target file into a target storage area. The target storage area may be a UBI volume that is mapped to a user partition. The UBI volume is a series of logical erase blocks. The file write instruction carries file write policy data.

[0061] Step 108: Based on the file writing policy data, write the compressed file into the first backup directory of the first logical erase block of the application partition to obtain a first backup file.

[0062] The file writing strategy data may be, but is not limited to, first writing the file into the first backup directory of the first logical erase block of the application partition to obtain the first backup file; then copying the first backup file into the second backup directory of the second logical erase block of the application partition to obtain the second backup file. The data of the first backup file and the second backup file are the same. When the first backup file is lost, the second backup file can be obtained from the second backup directory of the second logical erase block to avoid file loss and ensure data integrity.

[0063] Step 110, writing the first backup file into the second backup directory of the second logical erase block of the application partition to obtain the second backup file, thereby completing the processing of the flash memory partition data.

[0064] Specifically, based on the file writing strategy data, after backing up the compressed file in sequence to the first backup directory of the first logical erase block of the application partition and the second backup directory of the second logical erase block of the application partition, the data writing of the flash memory application partition is completed according to the mapping relationship between the logical erase block and the application partition. For example, when the system loses power abnormally, it is possible but not limited to obtain the first backup file from the first backup directory, and update the application program of the application partition according to the first backup file. When the first backup file is damaged, obtain the second backup file from the second backup directory, and update the application program of the application partition according to the second backup file.

[0065] In the above-mentioned flash memory partition data processing method, the first incremental file in the target subdirectory is first written into the memory, and the timer is triggered to count according to the initial preset value. When the timing value of the timer is the target preset value, the file carrying the first incremental file is compressed and the timer is reset; according to the file write instruction, the compressed file is written into the first backup directory of the first logical erase block and the second backup directory of the second logical erase block of the application partition to obtain the first backup file and the second backup file, and the processing of the flash memory partition data is completed; that is, by writing the incremental file into the memory, and delaying the storage of the file of the target subdirectory into the flash memory through the timer, and backing up the file, it is ensured that when the power is off during the file update process, the file is not written into the flash memory, so as to avoid the loss of data in the flash memory causing the system startup abnormality, thereby improving the stability of the system and the integrity of the data.

[0066] In one embodiment, Figure 2 As shown, a method for handling application partition mounting exceptions is provided. This embodiment uses the method applied to a terminal as an example. In this embodiment, the method includes the following steps:

[0067] Step 202: when an abnormal mounting of the application partition is detected, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain a first backup directory of the application partition.

[0068] The root file system is a file system based on the system partition in the flash memory, and the flash memory is divided into a system partition and an application partition.

[0069] Specifically, when the terminal detects an abnormal mounting of the application partition, it formats the application partition, and based on the root file system of the system partition, initializes the application partition according to the initial configuration file in the initial backup directory in the root file system to obtain the first backup directory of the application partition, that is, restores the initial settings of the application partition, which can also be understood as restoring the application partition to its factory state.

[0070] Step 204, determine whether the first MD5 value of the first backup directory in the application partition has passed the verification. If so, execute step 206, otherwise execute step 208.

[0071] The MD5 value refers to the Message Digest Algorithm (MD5), which treats the entire file as a large text message and generates a unique MD5 information digest through its irreversible string transformation algorithm.

[0072] Step 206: decompress the first backup directory and copy it to the target subdirectory.

[0073] Step 208: Obtain a second MD5 value of the second backup directory in the application partition.

[0074] Step 210, verify the second MD5 value to determine whether the second MD5 value passes the verification, if so, execute step 212, otherwise, execute step 214.

[0075] Step 212: decompress and copy the second backup directory to the target subdirectory.

[0076] Step 214: Copy the initial backup directory in the system partition to obtain a third backup directory, and copy the third backup directory to the target subdirectory.

[0077] Among them, the first, second, and third are used to distinguish the backup directories obtained from different locations. The first backup directory refers to the backup directory of the first logical erase block in the first logic in the application partition; the second backup directory refers to the backup directory of the second logical erase block in the second logic in the application partition; the third backup directory refers to the root file system based on the system partition, which is obtained by copying the initial backup directory in the root file system.

[0078] In the above-mentioned application partition mounting exception handling method, when the application partition is mounted abnormally, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain the first backup directory of the application partition; when the first MD5 value of the first backup directory in the application partition passes the verification, the first backup directory is decompressed and copied to the target subdirectory; when the first MD5 value of the first backup directory in the application partition fails to pass the verification, the directory in the target subdirectory is determined by verifying whether the second MD5 value of the second backup directory in the application partition is correct, to ensure the normal operation of the system and the normal reading and writing of the target subdirectory data.

[0079] In another embodiment, Figure 3 As shown, a flash memory partition data processing method is provided. This embodiment takes the method applied to a terminal as an example for illustration. In this embodiment, the method includes the following steps:

[0080] Step 302: When it is detected that there is a first incremental file in the target subdirectory of the mounted temporary file system, a timer is triggered to start timing from an initial preset value.

[0081] Optionally, in one embodiment, the flash memory includes a system partition and an application partition. When the first incremental file is detected in the target subdirectory of the mounted temporary file system, the application is started by mounting the system partition before the timer is triggered to start timing from the initial preset value; the application partition is mounted, and when an application partition mounting abnormality is detected, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain the first backup directory of the application partition; by detecting whether the application partition is mounted abnormally, the application partition with the mounting abnormality is formatted and initialized to ensure that data can be written normally.

[0082] Optionally, in one embodiment, after the application partition is initialized to obtain the first backup directory of the application partition, when the system is detected to be running, the first MD5 value of the first backup directory in the application partition is obtained; the first MD5 value is verified, and when the verification passes, the first backup directory is decompressed and copied to the target subdirectory; when the first MD5 value verification fails, the second MD5 value of the second backup directory in the application partition is obtained; the second MD5 value is verified, and when the verification passes, the second backup directory is decompressed and copied to the target subdirectory, when the second MD5 value verification fails, the initial backup directory in the system partition is copied to obtain a third backup directory, the third backup directory is copied to the target subdirectory, and the backup directory is verified according to the MD5 value to ensure the integrity and accuracy of the backup directory.

[0083] Step 304, when the timing value of the timer is not the target preset value, check whether there is a second incremental file in the target sub-directory, if so, execute step 306, otherwise, execute step 310.

[0084] Step 306, resetting the timer and updating the initial preset value, wherein the updated initial preset value is smaller than the initial preset value.

[0085] Step 308: trigger the timer to start timing from the updated initial preset value.

[0086] Specifically, when there is a first incremental file in the target subdirectory, the timer is triggered to count down from the initial preset value. During the countdown, it is detected that there is a second incremental file in the target subdirectory, that is, a file in the target subdirectory has been modified again. The timer is reset and the initial preset value is updated. The updated initial preset value is smaller than the initial preset value. The timer is triggered to count from the updated initial preset value. When the timing value of the timer is the target preset value, the file carrying the first incremental file is compressed and the timer is reset to obtain a compressed file. During the countdown, it is detected that a file in the target subdirectory has been modified again. By resetting the timer and updating the initial preset value, frequent writing is avoided to cause data errors, thereby improving data accuracy.

[0087] Step 310: When the timing value of the timer reaches the target preset value, the file carrying the first incremental file is compressed and the timer is reset to obtain a compressed file.

[0088] Step 312, generating a file writing instruction; the file writing instruction carries file writing policy data.

[0089] Step 314: based on the file writing policy data, write the compressed file into the first backup directory of the first logical erase block of the application partition to obtain a first backup file.

[0090] Step 316, write the first backup file into the second backup directory of the second logical erase block of the application partition to obtain the second backup file, and complete the processing of the flash memory partition data.

[0091] Optionally, in one embodiment, when a system status control instruction is received, the incremental files in the target subdirectory are compressed and the step of generating a file write instruction is executed, that is, the system status control instruction can be any one of a shutdown or restart instruction; the files in the target subdirectory are backed up and compressed to avoid data loss when the system is shut down or restarted.

[0092] like Figure 4 As shown, the following is an application scenario diagram of flash memory partition data processing in an embodiment.

[0093] After the terminal is powered on and the system partition is mounted, the application is started and the application partition is mounted. When an abnormal mounting of the application partition is detected, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain the first backup directory A of the application partition. When the system is detected to be running, the first MD5 value of the first backup directory A in the application partition is obtained; the first MD5 value is verified, and when the verification passes, the first backup directory is decompressed and copied to the target subdirectory; when the first MD5 value verification fails, the second MD5 value of the second backup directory B in the application partition is obtained; the second MD5 value is verified, and when the verification passes, the second backup directory B is decompressed and copied to the target subdirectory.

[0094] The background service process (for example, process A, process B, process C) monitors all files under directory D and monitors whether the files in the target subdirectory are modified. When it is detected that there is a first incremental file in the target subdirectory of the mounted temporary file system, the timer is triggered to start timing from the initial preset value; when the timing value of the timer is the target preset value, the file carrying the first incremental file is compressed and the timer is reset to obtain a compressed file; when the timing value of the timer is not the target preset value and it is detected that there is a second incremental file in the target subdirectory, the timer is reset and the initial preset value is updated; the updated initial preset value is less than the initial preset value; the timer is triggered to start timing from the updated initial preset value; when the timing value of the timer is the target preset value, the file carrying the second incremental file is compressed and the timer is reset, and the step of generating a file write instruction is executed.

[0095] Generate a file write instruction; the file write instruction carries file write strategy data; based on the file write strategy data, write the compressed file into the first backup directory of the first logical erase block of the application partition to obtain a first backup file; write the first backup file into the second backup directory of the second logical erase block of the application partition to obtain a second backup file, and complete the processing of the flash partition data; ensure the integrity of the file by verifying the MD5 value of the file in the application partition, and on the basis of ensuring the integrity of the file, when it is detected that the first incremental file exists in the target subdirectory, trigger the timer to start timing from the initial preset value, and delay the storage of the file in the target subdirectory; during the timing process of the timer, it is detected that the file in the target subdirectory is modified again, and the timer is reset and the initial preset value is updated to avoid frequent writing, resulting in data errors, thereby improving data accuracy.

[0096] In the above-mentioned flash memory partition data processing method, when it is detected that there is a first incremental file in the target subdirectory of the mounted temporary file system, the timer is triggered to count from the initial preset value. If it is detected that the file in the target subdirectory is modified again, the timer is reset and the initial preset value is updated, and the updated initial preset value is less than the initial preset value, the timer is triggered to count from the updated initial preset value. When the timing value of the timer is the target preset value, the file carrying the first incremental file is compressed and the timer is reset to obtain a compressed file; based on the file write strategy data, the compressed file is written into the first logical erase block and the second logical erase block of the application partition in sequence to obtain the first backup file and the second backup file, and the processing of the flash memory partition data is completed; according to the mapping relationship between the logical erase block and the application partition, the data writing of the flash memory application partition is completed to ensure that when the terminal system loses power abnormally, the incremental file is first written into the memory to avoid data loss in the flash memory causing system startup abnormality, thereby improving the stability of the system and the integrity of the data.

[0097] It should be understood that although Figure 1-3 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 1-3 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.

[0098] In one embodiment, Figure 5 As shown, a flash memory partition data processing device is provided, including: a detection module 502, a compression module 504, a generation module 506, a first writing module 508 and a second writing module 510, wherein:

[0099] The detection module 502 is used to trigger the timer to start timing from an initial preset value when it is detected that the first incremental file exists in the target subdirectory of the mounted temporary file system.

[0100] The compression module 504 is used to compress the file carrying the first incremental file and reset the timer to obtain a compressed file when the timing value of the timer reaches a target preset value.

[0101] The generating module 506 is used to generate a file writing instruction; the file writing instruction carries the file writing strategy data.

[0102] The first writing module 508 is used to write the compressed file into the first backup directory of the first logical erase block of the application partition based on the file writing policy data to obtain a first backup file.

[0103] The second writing module 510 is used to write the first backup file into the second backup directory of the second logical erase block of the application partition to obtain the second backup file and complete the processing of the flash memory partition data.

[0104] In the above-mentioned flash memory partition data processing device, the first incremental file in the target subdirectory is first written into the memory, and the timer is triggered to count according to the initial preset value. When the timing value of the timer is the target preset value, the file carrying the first incremental file is compressed and the timer is reset; according to the file write instruction, the compressed file is written into the first backup directory of the first logical erase block and the second backup directory of the second logical erase block of the application partition to obtain the first backup file and the second backup file, and the processing of the flash memory partition data is completed; that is, by writing the incremental file into the memory, and delaying the storage of the file of the target subdirectory into the flash memory through the timer, and backing up the file, it is ensured that when the power is off during the file update process, the file is not written into the flash memory, so as to avoid the loss of data in the flash memory causing the system startup abnormality, thereby improving the stability of the system and the integrity of the data.

[0105] In another embodiment, a flash memory partition data processing device is provided, which includes, in addition to a detection module 502, a compression module 504, a generation module 506, a first writing module 508 and a second writing module 510, a mounting module, an initialization module, an acquisition module, a verification module and a reset module, wherein:

[0106] The mount module is used to start the application after mounting the system partition.

[0107] The initialization module is used to mount the application partition. When an abnormal mounting of the application partition is detected, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain the first backup directory of the application partition.

[0108] The acquisition module is used to acquire the first MD5 value of the first backup directory in the application partition when detecting that the system is running.

[0109] The verification module is used to verify the first MD5 value, and when the verification passes, the first backup directory is decompressed and copied to the target subdirectory.

[0110] In one embodiment, the verification module is also used to obtain the second MD5 value of the second backup directory in the application partition when the first MD5 value verification fails; verify the second MD5 value, and when the verification passes, decompress and copy the second backup directory to the target subdirectory.

[0111] A reset module is used to reset the timer and update the initial preset value when the timing value of the timer is not the target preset value and a second incremental file is detected in the target subdirectory; the updated initial preset value is less than the initial preset value.

[0112] The detection module includes a trigger submodule, and the trigger submodule is used to trigger the timer to count from the updated initial preset value.

[0114] In one embodiment, the compression module 504 is further configured to compress the incremental files in the target subdirectory upon receiving a system status control instruction.

[0115] In one embodiment, after the terminal is powered on and the system partition is mounted, the application is started and the application partition is mounted. When an abnormality in the mounting of the application partition is detected, the application partition is formatted, and the application partition is initialized according to the initial configuration file in the initial backup directory of the root file system to obtain the first backup directory of the application partition.
