Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
FIG. 1 is a block diagram illustrating a method of system upgrade, according to an example embodiment. The execution main body of the system upgrading method provided by the embodiment may be a terminal, such as a mobile phone, a tablet computer, and the like. As shown in fig. 1, the method of the present embodiment may include the following steps:
in step 101, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, correctness checking is performed on the data in the target program storage area.
In this step, when the system is upgraded, the data of the system to be upgraded may be copied to the memory storage area, and then copied from the memory storage area to the program storage area. In this step, the target data to be upgraded is obtained according to the system upgrade package and stored in the target program storage area. Optionally, the first memory storage area may specifically be any part of a memory that can be used to copy data to the program storage area. The present disclosure is not limited with respect to the size of the first memory storage area. The target data may be all data or any part of data of the system to be upgraded. By checking the correctness of the data in the target program storage area, whether the data in the target program storage area is correct can be judged. Optionally, when the data in the target program storage area is consistent with the target data of the system to be upgraded, which is obtained according to the system upgrade package, the result of performing correctness check on the data in the target program storage area may be considered to be correct; when the data in the target program storage area is inconsistent with the target data of the system to be upgraded, which is obtained according to the system upgrade package, the result of the correctness check of the data in the target program storage area can be considered to be incorrect. Specifically, when the first memory storage area is not abnormal, the target data of the system to be upgraded in the first memory storage area and the target data of the system to be upgraded obtained according to the system upgrade package can be consistent; when the first memory storage area is abnormal, the target data of the system to be upgraded in the first memory storage area and the target data of the system to be upgraded obtained according to the system upgrade package may be inconsistent.
In step 102, if the result of checking the correctness of the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area.
In this step, the target data of the system to be upgraded, which is obtained according to the system upgrade package, is also stored in the second memory area. Optionally, after determining that the result of performing correctness check on the data in the target program storage area is incorrect, storing the target data of the system to be upgraded, which is obtained according to the system upgrade package, in the second memory storage area; or, before it is determined that the result of checking the correctness of the data in the target program storage area is incorrect, the target data of the system to be upgraded, which is obtained according to the system upgrade package, may be stored in the second memory storage area. The second memory area may specifically be a memory area different from the first memory area. When the target data of the system to be upgraded in the second memory storage different from the first memory storage area is copied to the target program storage area, the target data of the system to be upgraded in the second memory storage different from the first memory storage area can be copied to the target program storage area, so that the problem that the system is upgraded to an unusable version due to the memory abnormality is solved.
In the method for upgrading a system provided by this embodiment, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, correctness checking is performed on the data in the target program storage area, and if the result of correctness checking on the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, and the target data of the system to be upgraded is obtained according to the system upgrade package and is stored in the first memory storage area and the second memory storage area respectively, so that the problem that the terminal cannot normally operate due to the fact that the system is upgraded to an unusable version due to an abnormal memory is avoided, reliability of system upgrade is improved, and user experience is improved.
FIG. 2 is a block diagram illustrating a method of system upgrade, according to another example embodiment. Referring to fig. 2, the method provided in this embodiment mainly describes a specific implementation manner when the system upgrade package is the complete package on the basis of the embodiment of the method shown in fig. 1. As shown in fig. 2, the method of this embodiment may include:
in step 201, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, a first verification algorithm is used to perform correctness verification according to the data in the target program storage area and the data of the system upgrade package.
In this step, the target data of the system to be upgraded is obtained according to the system upgrade package and stored in the first memory area. Because the more contents needing to be updated in the program storage area, the longer the time required for upgrading, the more memories are used, the higher the probability of encountering memory abnormality in the upgrading process is, and the more contents need to be verified. Therefore, when the system upgrade package is a complete package, the partition of the program storage area may be used to divide the target data, and further, a checking algorithm with high accuracy may be selected as the first checking algorithm, for example, an md5sum checking algorithm. Specifically, whether the data in the target storage area is consistent with the target data of the system to be upgraded included in the data of the system upgrade package can be judged through a first verification algorithm, so that correctness verification is performed on the data in the target program storage area, if so, the result of the correctness verification is correct, and if not, the result is incorrect.
In step 202, if the result of checking the correctness of the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area.
It should be noted that step 202 is similar to step 102, and is not described herein again.
In the method for upgrading a system provided in this embodiment, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, correctness checking is performed by using a first checking algorithm according to the data in the target program storage area and the data of the system upgrade package, if the result of the correctness checking on the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, the target data of the system to be upgraded is obtained according to the system upgrade package and is stored in the first memory storage area and the second memory storage area respectively, so that the problem that the system is upgraded to an unusable version due to an abnormal memory, which results in that the terminal cannot normally operate, is avoided, and reliability of system upgrade is improved, the user experience is improved.
FIG. 3 is a block diagram illustrating a method of system upgrade, according to yet another example embodiment. Referring to fig. 3, the method provided in this embodiment mainly describes a specific implementation manner when the system upgrade package is a differential package on the basis of the embodiment of the method shown in fig. 1. As shown in fig. 3, the method of this embodiment may include:
in step 301, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, a second checking algorithm is used to perform correctness checking according to the data in the target program storage area, the data of the system upgrade package, and the backup data in the target program storage area.
In this step, the target data of the system to be upgraded is obtained according to the system upgrade package and stored in the first memory area. The backup data of the target program storage area is the data in the target program storage area before the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area. Because the content needing to be updated in the program storage area is less, the time required for upgrading is shorter, the used memory is less, the probability of encountering memory abnormality in the upgrading process is lower, and the content needing to be checked is less. Therefore, when the system upgrade package is a differential package, the division of the target data may be performed in the differential unit or the memory block of the program memory area, and further, a check algorithm with a high speed may be selected as the second check algorithm, for example, a parity check algorithm.
In step 302, if the result of checking the correctness of the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area.
It should be noted that step 302 is similar to step 102, and is not described herein again.
In the method for upgrading a system provided in this embodiment, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, correctness checking is performed by using a second checking algorithm according to the data in the target program storage area, the data of the system upgrade package, and the backup data of the target program storage area, if the result of the correctness checking performed on the data in the target program storage area is incorrect, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, and the target data of the system to be upgraded is obtained according to the system upgrade package and is respectively stored in the first memory storage area and the second memory storage area, so that the problem that the terminal cannot normally operate due to the fact that the system is upgraded to an unusable version due to an abnormal memory is avoided, the reliability of system upgrading is improved, and user experience is improved.
Optionally, on the basis of the embodiments shown in fig. 2 and fig. 3, before the system is upgraded, whether the system upgrade package is a legal upgrade package may be authenticated, and further, whether the system upgrade package is a complete package or a differential package may be determined. When the system upgrade package is a complete package, further, the technical solution of the embodiment shown in fig. 2 may be implemented; when the system upgrade package is a differential package, further, the technical solution of the embodiment shown in fig. 3 may be implemented.
FIG. 4 is a block diagram illustrating a method of system upgrade, according to yet another example embodiment. Referring to fig. 4, the method provided in this embodiment mainly describes an alternative implementation manner of performing correctness checking on data in a target program storage area on the basis of the embodiment of the method shown in fig. 1. As shown in fig. 4, the method of this embodiment may include:
in step 401, after the target data of the system to be upgraded in the first memory storage area is copied to the target program storage area corresponding to the target data, correctness checking is performed on the data in the target program storage area.
It should be noted that step 401 is similar to step 101, and is not described herein again.
In step 402, if the result of checking the correctness of the data in the target program storage area is incorrect, it is determined that the number of times of checking the correctness of the data in the target program storage area is incorrect is greater than or equal to a preset number of times.
In this step, when the number of times that the result of checking the correctness of the data in the target program storage area is incorrect is less than the preset number of times, step 403 is executed. When the number of times that the data in the target program storage area is checked for correctness is greater than or equal to the preset number of times, step 406 is executed.
In step 403, the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, and after the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, correctness checking is performed on the data in the target program storage area.
In this step, the target data of the system to be upgraded, which is obtained according to the system upgrade package, is also stored in the second memory area. Optionally, after determining that the result of performing correctness check on the data in the target program storage area is incorrect, storing the target data of the system to be upgraded, which is obtained according to the system upgrade package, in the second memory storage area; or, before it is determined that the result of checking the correctness of the data in the target program storage area is incorrect, the target data of the system to be upgraded, which is obtained according to the system upgrade package, may be stored in the second memory storage area. The second memory area may specifically be a memory area different from the first memory area.
It should be noted that, in this step, the specific manner of checking the correctness of the data in the target program storage area may refer to the related description in the foregoing embodiment, and is not described herein again.
In step 404, if the result of checking the correctness of the data in the target program storage area is incorrect, it is determined that the number of times of checking the correctness of the data in the target program storage area is incorrect is greater than or equal to a preset number of times.
In this step, when the number of times that the result of checking the correctness of the data in the target program storage area is incorrect is less than the preset number of times, step 405 is executed. When the number of times that the data in the target program storage area is checked for correctness is greater than or equal to the preset number of times, step 406 is executed.
In step 405, the target data of the system to be upgraded in the third memory storage area is copied to the target program storage area.
In this step, the target data of the system to be upgraded, which is obtained according to the system upgrade package, is also stored in the third memory area. It is to be understood that, after the target data of the system to be upgraded in the third memory storage area is copied to the target program storage area, correctness checking may also be performed on the data in the target program storage area, and similarly, when the result of correctness checking is incorrect and the number of times of correctness is less than the preset number of times, the target data of the system to be upgraded in the fourth memory storage area may be copied to the target program storage area … … until the result of correctness checking is correct or until the number of times of correctness checking is incorrect is greater than or equal to the preset number of times.
In step 406, the data in the program storage area is returned to the data corresponding to the current system, and the program storage area includes the target program storage area.
In this step, the data in the program storage area may be returned to the data corresponding to the current system according to the data in the backup storage area of the program storage area. The backup storage area stores data corresponding to the current system.
In the method for upgrading a system provided in this embodiment, after the target data of the system to be upgraded in the second memory storage area is copied to the target program storage area, correctness verification is performed on the data in the target program storage area, and if the result of the correctness verification performed on the data in the target program storage area is incorrect, the target data of the system to be upgraded in the third memory storage area is copied to the target program storage area, so that reliability of system upgrading is further improved. In addition, if the number of times of correctness check on the data in the target program storage area is incorrect is greater than or equal to the preset number of times, returning the data in the program storage area to the data corresponding to the current system, wherein the program storage area comprises the target program storage area, so that the availability of the current system is ensured when the system is not upgraded successfully, and the user experience is improved.

Referring to fig. 5A and 5B, the method provided in this embodiment describes an alternative implementation manner, based on the above method embodiment, by taking an example that the target data of the system to be upgraded is composed of target data 1 and target data 2. As shown in fig. 5A, the method of the present embodiment may include:
in step 501, the target data 1 of the system to be upgraded in the first memory storage area 1 is copied to the target program storage area 1 corresponding to the target data 1.
In this step, the target data 1 of the system to be upgraded is obtained according to the system upgrade package and stored in the first memory area 1.
In step 502, the data in the target program storage area 1 is checked for correctness.
In this step, if the result of checking the correctness of the data in the target program storage area 1 is incorrect, step 503 may be executed. If the result of checking the correctness of the data in the target program storage area 1 is correct, step 504 can be executed. For a specific implementation manner of performing correctness check on the data in the target program storage area 1, reference may be made to the above embodiment, which is not described herein again.

In this step, the target data 1 of the system to be upgraded is obtained according to the system upgrade package and is also stored in the second memory area 1. It should be noted that, in this embodiment, step 504 may be executed after step 503 is executed, and optionally, after step 503 is executed, the embodiment shown in fig. 4 may further perform validity check on the data in the target program storage area 2, and step 504 is executed again until the result of the validity check is correct.
In step 504, the target data 2 of the system to be upgraded in the first memory storage area 2 is copied to the target program storage area 2 corresponding to the target data 2.
In this step, the target data 2 of the system to be upgraded is obtained according to the system upgrade package and stored in the first memory storage area 2.
In step 505, the data in the target program storage area 2 is checked for correctness.
In this step, if the result of checking the correctness of the data in the target program storage area 2 is incorrect, step 506 may be executed. If the result of the correctness check on the data in the target program storage area 2 is correct, the system upgrade is finished, and if the result of the correctness check on the data in the target program storage area 2 is correct, the system upgrade can be indicated to be finished. For a specific implementation manner of performing correctness check on the data in the target program storage area 1, reference may be made to the above embodiment, which is not described herein again.
In step 506, the target data 2 of the system to be upgraded in the second memory storage area 2 is copied to the target program storage area 2.
In this step, the target data 2 of the system to be upgraded is obtained according to the system upgrade package and is also stored in the second memory area 2. It should be noted that, after the step 506 is executed, the process may be ended, or the validity check may be further performed on the data in the target program storage area 2 as in the embodiment shown in fig. 4. It should be noted that, in this embodiment, taking an example that the target data 1 is copied to the target program storage area 1 first, and then the target data 2 is copied to the target program storage area 2, the sequence of copying the target data 1 and the target data 2 is not limited in this disclosure.
