Detailed Description
For the purposes of making the objects, technical solutions and advantages of the present application more apparent, the present application will be described in further detail below with reference to the accompanying drawings, wherein it is apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that the terms "comprises" and "comprising," along with their variants, 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 words appearing hereinafter are explained:
(1) Linux: the universal GNU/Linux is a free-to-use and freely-spread UNIX-like operating system. It can run major Unix tools, applications, and networking protocols. It supports 32-bit and 64-bit hardware. Linux inherits the design idea of Unix with a network as a core, and is a multi-user network operation system with stable performance. There are hundreds of different releases for Linux, such as debian, archlinux based on community development, red Hat Enterprise Linux based on commercial development, SUSE, oracle Linux, etc. The Linux operating system regards all devices as files, which integrates the resources of the entire computer into one large file directory. To access a file in a storage device, a user must mount the partition in which the file resides to an existing directory and then access the storage device by accessing this directory.
(2) NOR Flash: the NOR Flash is a memory adopting nonvolatile Flash technology, and is characterized by an XIP (eXecute In plane) execution, so that an application program can directly run In the Flash without reading codes into a system RAM. The transfer efficiency of NOR Flash is high, with high cost effectiveness at small capacities of 1-4 MB.
(3) Mounting (mount): 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 for access through the computer's file system by an operating system. Typically, when the computer is shut down, each mounted storage will undergo an uninstallation to ensure that all queued data is written to and to ensure the integrity of the on-media file system structure. In Linux operating systems, mounting is a very important function, which is used very frequently, in particular to mount a device (typically a storage device) to an existing directory.
(4) Flash Memory (Flash Memory): is a long-life non-volatile (still maintaining stored data information in the event of a power failure) memory, and data deletion is not in units of a single byte but in units of a fixed block (note: NOR Flash is a byte store.) the block size is typically 256KB to 20MB. Flash memory is a variation of electrically erasable read-only memory (EEPROM), which differs from EEPROM in that EEPROM can be erased and rewritten on a byte level rather than an entire chip, while most chips of flash memory require block erasure. Flash memory is commonly used to store setup information, such as data stored in the BIOS (basic program) of a computer, a PDA (personal digital assistant), a 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 (IPC), is widely applied in various scenes of industry at present, and as the cost requirement is higher and higher, a FLASH memory (FLASH) is generally used as a storage device, and a low-capacity NOR FLASH is used for storage in a mainstream low-cost scheme at present. FLASH (FLASH) memory 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 the user data area and partition table, often mounted using the JFFS2 file system in a low capacity NOR FLASH. For reasons of storage space, etc., this type of terminal equipment is generally not provided with a backup area for the user data area.
In the existing program upgrading method, if the terminal equipment is provided with a backup area of user data, if power failure, abnormal restarting and other conditions occur during user data updating, the user data can be recovered when lost. However, this type of terminal device typically does not have a backup area for the user data area, for storage space or 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, the embodiment of the application provides a program upgrading method, a device, a medium and electronic equipment, wherein version file partitions and partition tables contained in a flash memory are updated according to an upgrading data packet by responding to a received program upgrading instruction input by a user; dividing a 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 files 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 is abnormal. When the method is used for program upgrading of terminal equipment without a backup area of a user data area, the user data area of the flash memory is divided into a target user data area and at least one backup user data area according to the updated partition table, the data of the target user data area and the data of each backup user data area are integrated into a spliced file, and the original user data is reserved and further backed up according to the spliced file, so that the terminal equipment without the backup area can obtain the backup area.
For the purpose of promoting an understanding of the principles of the invention, reference will now be made in detail to the embodiments, some but not all of which are illustrated in the accompanying drawings. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that, the application scenario described in the embodiment of the present application is for more clearly describing the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art can know, with the appearance of the new application scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.
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 for the terminal device 200. The terminal device 200 comprises a flash memory 201. It can be understood that the server 100 and the terminal device 200 may also be respectively located in different data networks connected to each other, and the same data network of the application scenario described in fig. 1 does not constitute a limitation on the technical solution provided in the embodiments of the present application. Fig. 2 shows a schematic diagram of a flash memory partition 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 division of the flash memory; the kernel area is used for storing kernel files; the ROOTFS area contains the directory and critical files necessary for system start-up, and files necessary for other file systems to mount; the user data area typically stores user data. Only the user data area and the partition table in the above-mentioned partition of the flash memory partition are writable. The other several partitions, except the user data area and the partition table area, obtained by partitioning the flash memory may be collectively referred to as version file partitions. When the program of the terminal device 200 is updated, the updated version program can be implemented by updating the BOOT area, the partition table, the kernel area, the ROOTFS area, and the user data area included in the flash memory 201 of the terminal device 200. In the following embodiments of the present application, the partition of the flash memory 201 of the terminal device 200 includes a version file partition, a user data area, and a partition table, where the version file partition includes a BOOT area, a kernel area, and a ROOTFS area, which are described as examples.
The server 100 periodically pushes a program upgrade reminder message to the terminal device 200, and the user can confirm the received program upgrade reminder message by clicking the terminal device 200, thereby inputting a program upgrade instruction to the terminal device 200. In response to a received program upgrading instruction input by a user, the terminal device 200 updates the version file partition and the partition table contained in the flash memory 201 according to an upgrading data packet; dividing a 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; writing the spliced files into the target user data area and each backup user data area respectively; wherein 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.
The embodiment of the application provides a program upgrading method, as shown in fig. 3, comprising the following steps:
step S301, in response to the received program upgrade instruction input by the user, updates the version file partition and the partition table contained 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 packet from the server 100 in response to a received program upgrade instruction input by a user, and updates a version file partition and a partition table included in the flash memory 201 according to the upgrade data packet, wherein the version file partition is other partition than the partition table and the user data area among a plurality of preset partitions included in the flash memory 201 for storing program data of the program: BOOT area, kernel area, ROOTFS area.
Step S302, the user data area of the flash memory is divided into a target user data area and at least one backup user data area according to the updated partition table.
In the embodiment of the present application, the process of dividing the user data area in the flash memory according to the updated partition table may be divided into the target user data area and one backup user data area, or may be divided into the target user data area and a plurality of backup user data areas. The number of backup user data areas obtained by dividing is not particularly limited in the present application.
In some alternative embodiments, the division of 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 achieved 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 acquired when the terminal device updates the partition table. The acquisition modes of the user data area parameters include, but are not limited to: user input data are collected, and preset default parameters are obtained.
When the terminal acquires the parameters of the user data area by acquiring the user input data, the number of divisions input by the user, the start address and the storage capacity corresponding to each divided new user data area may be acquired. The dividing number indicates that the whole storage area of the user data area before upgrading needs to be divided into a plurality of 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 divisions of the user data area, the start address, and the storage capacity input by the user in response to the prompt information prompting the user to input the user data area parameters.
When the terminal obtains the parameters of the user data area by obtaining the preset default parameters, the number of divisions of the preset user data area, the starting address and the storage capacity of each divided new user data area can be directly obtained.
Illustratively, when updating the partition table, the terminal device 200 may directly obtain the number of divisions of the user data area, the start address and the storage capacity of each divided new user data area according to the preset data, to obtain the updated partition table.
Fig. 4 is a schematic diagram showing a user data area divided into two at the time of program update according to an embodiment of the present application. As shown in fig. 4, after upgrading the BOOT area, the kernel area, the ROOTFS area, and the partition table according to the program upgrade package, the terminal device 200 adjusts the partition positions according to the new partition table, so that the user data area before upgrading can be divided into two parts, thereby obtaining the user data area 1 and the user data area 2. It can be understood that, the division of the user data area before upgrading into two in fig. 4 is merely illustrative, and the program upgrading method provided in the embodiment of the present application may also divide the user data area before upgrading into more user data areas, and fig. 4 does not constitute a limitation on 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 suitable for multiple upgrades of terminal devices in a backup area where no user data area is set. If the user data area of the flash memory is already divided into two or more partitions during the previous upgrade of the terminal device, 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 updated partition table of the upgrade during the upgrade: if the user data area parameter of the updated partition table is unchanged compared with the user data area parameter of the previous upgrade, the target user data area and at least one backup user data area obtained by the upgrade are consistent with the upgrade of the previous time; if the user data area parameter of the updated partition table is changed compared with the previous upgrade, the target user data area and at least one backup user data area obtained by the upgrade are different from the last upgrade, that is, the user data area parameter is obtained according to the updated partition table of the upgrade, and the user data area of the terminal equipment is re-divided, 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, alarm information is generated.
Illustratively, when the terminal device 200 divides the user data area of the flash memory into the target user data area and at least one backup user data area according to the updated partition table, it determines whether only one user data area exists in the updated partition table, and if it determines that only one user data area exists in the updated partition table, generates alert information to indicate a reminder. For example, a prompt message of "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 splice file data.img. It is understood that the spliced files herein are merely examples, and other file types of spliced files are equally applicable to the embodiments of the present application.
