Detailed Description
In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that references in the specification of the present application to the terms "comprises" and "comprising," and variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Some of the words that appear in the text are explained below:
(1) and Linux: the general name GNU/Linux is a UNIX-like operating system which is free to use and spread freely. It can run major Unix tool software, applications, and network protocols. It supports 32-bit and 64-bit hardware. Linux inherits the design idea of Unix with network as core, and is a multi-user network operating system with stable performance. There are hundreds of different releases for Linux, such as debian, archlinux based on community development, and Red Hat Enterprise Linux, SUSE, Oracle Linux, etc. based on commercial development. The Linux operating system treats all devices as files, and integrates the resources of the entire computer into a large file directory. To access a file on a storage device, a user must mount the partition in which the file resides on an existing directory and then access the storage device by accessing the directory.
(2) NOR Flash: NOR Flash is a memory that uses non-volatile Flash technology and is characterized by on-chip execution (XIP), so that applications can run directly In Flash without having to read the code into the system RAM. NOR Flash has high transmission efficiency and has high cost benefit when the capacity is small, namely 1-4 MB.
(3) Mounting (Mounting): refers to a process by which computer files and directories on a storage device (such as a hard disk, CD-ROM, or shared resource) are made available to a user through the computer's file system by an operating system. Generally, when a computer is shut down, each mounted storage will undergo an offload to ensure that all queued data is written and to ensure the integrity of the file system structure on the media. In the Linux operating system, mounting is a very important function, which is used very frequently, and is specifically to mount a device (usually a storage device) to an existing directory.
(4) Flash Memory (Flash Memory): is a long-lived, non-volatile (maintaining stored data information in the event of a power failure) memory, with data erasures not in individual bytes but in fixed blocks (note: NOR Flash is a byte store), typically 256KB to 20MB in block size. Flash memory is a variation of electrically erasable read-only memory (EEPROM) which, unlike EEPROM, can be erased and rewritten on a byte level rather than being erased on an entire chip, whereas most chips of flash memory require block erasure. Flash memory is commonly used to store setup information, such as BIOS (basic program) of a computer, PDA (personal digital assistant), digital camera, etc., because it can still store data when it is powered off.
Terminal equipment using a Linux system, such as an internet protocol Camera (IP Camera, IPC), is currently widely used in various scenes in the industry, and with higher and higher cost requirements, a FLASH memory (FLASH) is generally adopted as a storage device, and a low-capacity NOR FLASH is adopted for storage in a mainstream low-cost scheme at present. FLASH memory (FLASH) is often divided into a BOOT area, a partition table, a kernel area, a ROOTFS area, and a user data area. All partitions are writable only with user data areas and partition tables, and in small-capacity NOR FLASH, the JFFS2 file system is often used for mounting. This type of terminal device is not normally provided with a backup area for the user data area for reasons such as storage space.
In the existing program upgrading method, if the terminal equipment has a backup area of user data, if the user data is updated and the conditions such as power failure and abnormal restart occur, the user data can be recovered when lost. However, this type of terminal device generally does not have a backup area for the user data area for reasons of storage space and the like. Therefore, how to provide a program upgrading method for enabling terminal equipment without a backup area to obtain the backup area has important practical significance.
In order to solve the existing technical problems, embodiments of the present application provide a method, an apparatus, a medium, and an electronic device for program upgrade, in which a version file partition and a partition table included in a flash memory are updated according to an upgrade data packet by responding to a received program upgrade instruction input by a user; dividing the user data area of the flash memory into a target user data area and at least one backup user data area according to the updated partition table; integrating the data of the target user data area and the data of each backup user data area into a spliced file; writing the spliced file into the target user data area and each backup user data area respectively; and the backup user data area is used for enabling the program to be started normally when the data of the target user data area are abnormal. When the program of the terminal equipment of the backup area without the user data area is upgraded, the method divides the user data area of the flash memory into a target user data area and at least one backup user data area according to the updated partition table, integrates the data of the target user data area and each backup user data area into a splicing file, and realizes the retention and further backup of the original user data according to the splicing file, thereby leading the terminal equipment without the backup area to obtain the backup area.
In order to make the objects, technical solutions and advantages of the embodiments of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the following application scenarios described in the embodiments of the present application are for more clearly illustrating the technical solutions in the embodiments of the present application, and do not constitute limitations on the technical solutions provided in the embodiments of the present application, and it is obvious to a person skilled in the art that the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems with the occurrence of new application scenarios.
Fig. 1 shows an application scenario provided in an embodiment of the present application, and referring to fig. 1, the application scenario includes a terminal device 200 and a server 100. The server 100 and the terminal device 200 are in the same data network, which may be a wired network or a wireless network. When the server 100 and the terminal device 200 are in the same data network, the terminal device 200 can communicate with the server 100. The server 100 may be a cloud server that performs an upgrade service on the terminal device 200. The terminal device 200 includes a flash memory 201. It is understood that the server 100 and the terminal device 200 may also be respectively in a state of interconnecting different data networks, and the same data network of the application scenario depicted in fig. 1 does not constitute a limitation to the technical solution provided in the embodiment of the present application. Fig. 2 is a schematic diagram illustrating a partition of a flash memory according to an embodiment of the present application. As shown in fig. 2, the flash memory is mainly divided into a BOOT area, a partition table, a kernel area, a ROOTFS area, and a user data area. The BOOT area is generally used for storing a core file used when Linux is started; the partition table is a guide file for uniformly managing the partition of the flash memory; the kernel area is used for storing kernel files; the ROOTFS area contains directories and critical files necessary for system startup and files necessary for other file systems to be mounted; the user data area typically stores user data. Only the user data area and the partition table are writable in the above partition divided by the flash memory. The other partitions obtained by partitioning the flash memory except the user data partition and the partition table may be collectively referred to as version file partitions. When the program of the terminal device 200 is upgraded, the update version program may be implemented by updating a BOOT area, a partition table, a kernel area, a ROOTFS area, and a user data area included in the flash memory 201 of the terminal device 200. In the following embodiments of the present application, the flash memory 201 of the terminal device 200 is partitioned to include a version file partition, a user data partition, and a partition table, where the version file partition includes a BOOT area, a kernel area, and a ROOTFS area.
The server 100 may not periodically push the program upgrade alert message to the terminal device 200, and the user may click to confirm the received program upgrade alert message through the terminal device 200, thereby inputting the program upgrade instruction to the terminal device 200. The terminal device 200 updates the version file partition and the partition table included in the flash memory 201 according to the upgrade data packet in response to the received program upgrade instruction input by the user; dividing the user data area of the flash memory 201 into a target user data area and at least one backup user data area according to the updated partition table; integrating the data of the target user data area and the data of each backup user data area into a spliced file; respectively writing the spliced file into a target user data area and each backup user data area; the backup user data area is used for enabling the program to be started normally when the data of the target user data area is abnormal.
An embodiment of the present application provides a program upgrading method, as shown in fig. 3, including the following steps:
step S301, in response to a received program upgrade instruction input by a user, updating a version file partition and a partition table included in the flash memory according to the upgrade data packet.
The flash memory comprises a plurality of preset partitions for storing program data of a program; the plurality of preset partitions comprise a version file partition, a partition table and a user data area for storing user data; the partition table is used for determining the storage position of each preset partition.
Optionally, the version file partition includes a BOOT area, a kernel area, and a ROOTFS area.
Illustratively, the terminal device 200 downloads an upgrade data package from the server 100 in response to a received program upgrade instruction input by a user, and updates the version file partition and the partition table included in the flash memory 201 according to the upgrade data package, wherein the version file partition is a partition other than the partition table and the user data partition, among a plurality of preset partitions included in the flash memory 201 for storing program data of the program: a BOOT area, a kernel area and a ROOTFS area.
Step S302, according to the updated partition table, the user data area of the flash memory is divided into a target user data area and at least one backup user data area.
In the embodiment of the application, the process of dividing the user data area in the flash memory according to the updated partition table may be divided into a target user data area and one backup user data area, or divided into the target user data area and a plurality of backup user data areas. The number of the divided backup user data areas is not particularly limited.
In some optional embodiments, dividing the user data area of the flash memory into the target user data area and the at least one backup user data area according to the updated partition table may be implemented by:
and adjusting the storage address of the user data area according to the user data area parameters in the updated partition table so as to divide the user data area of the flash memory into a target user data area and at least one backup user data area.
The user data area parameters are obtained when the terminal device updates the partition table. The obtaining method of the user data area parameters includes but is not limited to: collecting user input data and acquiring preset default parameters.
When the terminal acquires the user data area parameters by collecting the user input data, the number of divisions input by the user, the start address and the storage capacity corresponding to each new divided user data area may be acquired. The division quantity indicates that the whole storage area of the user data area before the upgrade needs to be divided into several user data areas.
Illustratively, the user data area parameters include a start address and a storage capacity of the user data area. When updating the partition table, the terminal device acquires and stores the number of partitions, the start address, and the storage capacity of the user data area, which are input by the user in response to prompt information prompting the user to input parameters of the user data area.
When the terminal acquires the user data area parameters by acquiring the preset default parameters, the number of partitions of the preset user data area, the start address of each partitioned new user data area, and the storage capacity can be directly acquired.
For example, when updating the partition table, the terminal device 200 may directly obtain the number of partitions of the user data area, the start address and the storage capacity of each new partitioned user data area according to the preset data, and obtain the updated partition table.
Fig. 4 is a schematic diagram illustrating a user data partition in two during program update according to an embodiment of the present application. As shown in fig. 4, after the BOOT area, the kernel area, the ROOTFS area, and the partition table are updated according to the program update package, the terminal device 200 adjusts the positions of the partitions according to the new partition table, so that the user data area before the update can be divided into two, and the user data area 1 and the user data area 2 are obtained. It can be understood that, the division of the user data area before the upgrade in fig. 4 is merely an example, the program upgrade method provided in the embodiment of the present application may further divide the user data area before the upgrade into more user data areas, and fig. 4 does not constitute a limitation to the technical solution provided in the embodiment of the present application.
It can be understood that the program upgrading method provided in this embodiment is also applicable to upgrading a terminal device without setting a backup area of a user data area for multiple times. If the user data area of the flash memory is divided into two or more partitions during the previous upgrade of the terminal equipment, the user data area of the flash memory is still divided into a target user data area and at least one backup user data area according to the partition table updated by the upgrade during the upgrade: if the user data area parameters of the updated partition table during the upgrade are unchanged from the user data area parameters during the previous upgrade, the target user data area and at least one backup user data area obtained by the partition of the upgrade are consistent with the partition of the upgrade at the previous time; if the user data area parameters of the updated partition table during the upgrade are changed compared with the previous upgrade, the target user data area and the at least one backup user data area obtained by the partition of the upgrade are different from the partition of the previous upgrade, that is, the user data area parameters are obtained according to the updated partition table of the upgrade, and the user data area of the terminal equipment is re-partitioned, so that a new target user data area and a new at least one backup user data area are obtained.
In some embodiments of the present application, when the user data area of the flash memory is divided into the target user data area and the at least one backup user data area according to the updated partition table, if it is determined that only one user data area exists in the updated partition table, an alarm message is generated.
Illustratively, the terminal device 200 determines whether the updated partition table has only one user data area when the user data area of the flash memory is divided into the target user data area and the at least one backup user data area according to the updated partition table, and generates an alarm message to indicate a reminder if the updated partition table has only one user data area. For example, a prompt message "error, only in one user data area" is displayed.
Step S303, integrating the data of the target user data area and each backup user data area into a spliced file.
Illustratively, the terminal device 200 integrates the data of the target user data area and the respective backup user data areas into a spliced file data. It is understood that the concatenation file is only an example, and other file types of concatenation files are also applicable to the embodiment of the present application. The following embodiments of the present application are all described by taking the concatenation file data.
In some embodiments of the present application, integrating the data of the target user data area and each backup user data area into a spliced file specifically includes: and reading data from the target user data area and each backup user data area according to the sequence of the storage addresses, and integrating the data into a spliced file based on the reading sequence.
