Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1, a method for updating a partitionable system includes the following steps, when the system needs to be upgraded, S2, dividing a storage space into a storage block with a size larger than an upgrade file of a largest partitionable functional unit among all partitionable functional units in the system, taking the storage block as an upgrade auxiliary partition, and correspondingly partitioning storage addresses of all n partitionable functional units to obtain n partition units. In the system, the separable functional units may be functional units with a near root directory, such as kernel units, rootfs units, OEM units, APP units, etc., that can be verified for full functionality. In other embodiments, the separable functional units may also be functional units with different loading stages in the starting process of the system, for example, rootfs is a user mode program and a file system, kernel is a kernel, and the loaded time nodes are different and are divided into different partitions. In other classifications, the functional unit may also be a functional unit with a different mirror file system, for example, a kernel does not have a so-called file system and a rootfs has a file system.
S3, sorting all the n partition units according to size, downloading the upgrade files corresponding to the first partition unit to the upgrade auxiliary partition, deleting the files in the first partition unit,
and S4, downloading the upgrade file corresponding to the ith partition unit to the (i-1) th partition unit, deleting the file in the ith partition unit, and taking i from 2 to n.
Through the scheme, the cyclic backup can be carried out only by the storage space in the system having the storage block with the size larger than the upgrade file of the largest separable functional unit in all separable functional units in the system, the upgrade file corresponding to the ith partition unit is downloaded to the (i-1) th partition unit, the file in the ith partition unit is deleted, and the iteration is continued, so that the upgrade files of the separable functional units in all the partition units are all updated finally. The requirement of firmware upgrading in the electronic device with small storage space is met.
In a further embodiment, the method further comprises the steps of downloading the upgrade file corresponding to the ith partition unit to the ith-1 th partition unit, deleting the file in the ith partition unit, and marking the starting path of the ith partitionable function unit as the ith-1 st partitionable unit. Through the steps, the new functional unit can be started through a new path, the problem that the functional unit is not correct when the system runs is avoided, and possible errors of the system are reduced.
In other embodiments, the upgrade file corresponding to the ith partition unit is downloaded to the (i-1) th partition unit, and the file in the ith partition unit is deleted only after the upgrade file in the (i-1) th partition unit is verified. According to the scheme, after the newly downloaded upgrade file is verified, if the integrity of the upgrade file can be verified, the upgrade file can be normally compatible, the file in the original storage position is deleted, the problem that the system runs the new upgrade file incorrectly is avoided, and possible errors of the system are reduced.
In the embodiment shown in fig. 1, step S1 is further included to pre-read the size of the upgrade file of the largest separable functional unit among all the upgrade files. The step can read all the upgrading files in advance and find out the size of the upgrading file of the largest divisible functional unit, so that the size of the upgrading auxiliary partition needing to be divided can be directly determined in advance, the possibility of insufficient size of the upgrading auxiliary partition is reduced, and the feasibility and the fault tolerance rate of the scheme are improved.
In other embodiments, the upgrade auxiliary partition may be further divided by dividing all the storage space into +1 equal-sized storage blocks according to the number of the separable functional units, where the separable functional units are respectively stored and operated in different partitions, and an extra block serves as the upgrade auxiliary partition. This also does not create the problem of the upgrade file being larger than the upgrade auxiliary partition size. Further, in the embodiment shown in fig. 2, we take the separable functional units including a kernel partition, a rootfs partition, and an OEM partition as an example, and perform a flow description:
firstly, dividing a system storage space (assumed to be 16M) into 4 spaces with the same size, wherein each storage space is 4M, three partitions store kernel A, rootfs A and OEMA of a running system, and a blank partition is reserved and is an upgrade auxiliary partition (F partition).
The upgrade flow of the system can be seen from the left part of fig. 2, and the partition change situation in each step can be seen from the right part of fig. 2. Specifically, in the first step, the kernel is upgraded, the upgrade file kernel B is downloaded to the upgrade auxiliary partition F partition, after the kernel B to be verified can be upgraded successfully, the next time the kernel B is started from the F partition is marked, and meanwhile, the kernel A in the K partition is emptied. The second step is that: and downloading the rootfs B to the K partition, marking the starting rootfs B from the K partition after the rootfs B can be successfully upgraded and emptying the rootfs A in the R partition. The third step: and downloading the OEM B to the R partition, marking the next time of starting the OEM from the R partition after the OEM B to be verified can be successfully upgraded, and simultaneously emptying the OEMA in the O partition. And finishing upgrading.
The benefit of the above scheme is. Assuming that the number of partitions of a certain product system is N and the number of partitions required for normal AB upgrade is 2 × N, the number of partitions required is N +1 by the method described in this patent. Aiming at the aforementioned products with 3 partitions, the A/B upgrade is realized by 6 partitions in the normal way, and the A/B upgrade can be completed by only 4 partitions with the same size. The storage space of the product is saved, and the method can be stated as follows: the A/B upgrading is realized on a small-capacity storage space. Secondly, when the version is updated next time, such as the version C, the current O partition is empty and can be used for downloading the target version of one partition, such as kernel C, and the updating of the version C can be completed by repeating the steps, so that the subsequent iteration version is convenient.
A partitionable system updates the storage medium, store the computer program, the said computer program is carried out when being run and includes the following step, when the system needs to upgrade, divide out the memory block greater than the size of the staging file of the largest partitionable functional unit in all partitionable functional units in the system in the memory space, as the auxiliary partition of staging;
correspondingly partitioning the memory addresses of all n separable functional units to obtain n partition units,
sorting all the n partition units according to size, downloading the upgrade files corresponding to the first partition unit to the upgrade auxiliary partition, deleting the files in the first partition unit,
and downloading the upgrade file corresponding to the ith partition unit to the (i-1) th partition unit, deleting the file in the ith partition unit, and taking i from 2 to n.
Specifically, the computer program further executes the steps of downloading the upgrade file corresponding to the ith partition unit to the (i-1) th partition unit, deleting the file in the ith partition unit, and marking the starting path of the ith partitionable function unit as the (i-1) th partitionable unit when the computer program is executed.
Specifically, the separable functional units comprise a kernel unit, a rootfs unit, an OEM unit, and an APP unit.
Further, the computer program further executes the steps of downloading the upgrade file corresponding to the ith partition unit to the (i-1) th partition unit, and deleting the file in the ith partition unit after checking the upgrade file in the (i-1) th partition unit.
Specifically, the computer program further performs a step of, when executed, pre-reading the size of the upgrade file of the largest dividable functional unit among all the upgrade files. It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
