Background
The target software upgrading method is one technology for upgrading target software. At present, when upgrading target software, the method generally adopted is as follows: first, the control unit erases the entire piece of flash data. And then, performing data writing operation on the whole flash memory by taking a frame as a unit for the software upgrading package data corresponding to the target software. Thus, the target software is upgraded.

secondly, before the target software is upgraded, the verification of the data source safety is often easily ignored, or the verification process is too complex, so that the safety and efficiency of the target software upgrading are low;
thirdly, if the data transmission is interrupted due to power failure or network disconnection, the control unit needs to erase the whole flash memory data again, receive the whole software upgrading program package again by taking the frame as a unit and perform data writing operation on the whole flash memory by taking the frame as a unit, thereby resulting in lower efficiency of upgrading the target software.

The above embodiments of the present disclosure have the following beneficial effects: by the target software upgrading method of some embodiments of the present disclosure, the efficiency of upgrading target software can be improved. Specifically, the reasons for the inefficiency of upgrading the target software are: with the increasing frequency of software upgrading and the increasing amount of flash memory data, the whole flash memory data is written in a flashing manner during each upgrading, which takes longer time, and leads to the lower efficiency of target software upgrading. Based on this, the target software upgrading method of some embodiments of the present disclosure first obtains a software identification information set.

Therefore, the program storage partition data corresponding to each target software to be upgraded can be sequentially refreshed, time consumed for upgrading is shortened, and therefore the upgrading efficiency of the target software can be improved. Therefore, according to some target software upgrading methods disclosed by the disclosure, in each software upgrading process, only the program storage partition data corresponding to each software to be upgraded needs to be refreshed, and the whole flash memory data does not need to be refreshed. Thus, the time consumed for upgrading is shortened. Furthermore, the upgrading efficiency of the target software can be improved.

The identifier matching success information may be used to represent that each target software identifier in the target software identifier group is the same as the software identifier corresponding to each piece of software identifier information in the software identifier information set. The identifier matching failure information may be used to characterize that the target software identifier in the target software identifier group is different from the software identifiers included in the software identifier information sets. The execution main body may generate the third verification information based on the target software identification group and the software identification information set in various manners.
In some optional implementations of some embodiments, each piece of software identification information in the set of software identification information may include a software identification. In response to determining that the second verification information satisfies a second preset verification condition, the execution subject may generate third verification information based on the target software identification group and the software identification information set by:

And a second substep of determining the identifier matching failure information as third verification information if at least one target software identifier in the target software identifier group is different from the software identifiers included in the software identifier information sets.
And a third substep of determining the successful identifier matching information as third verification information if each target software identifier in the target software identifier group is the same as the software identifier included in each piece of software identifier information in the software identifier information set.
And fifthly, in response to the fact that the third verification information meets a third preset verification condition, sequencing the target software identifiers in the target software identifier group to obtain a target software identifier sequence. The third preset verification condition may be that the third verification information is identification matching success information. The target software identification sequence may be a sequence obtained by arranging the target software identifications in the target software identification group from small to large. The target software identifiers in the target software identifier group can be sequenced through a preset sequencing algorithm, so that a target software identifier sequence is obtained.
As an example, the preset ranking algorithm may include, but is not limited to, at least one of the following: bubble ordering, insert ordering, hill ordering, and the like.
Optionally, the subscription information may be generated as follows:

The steps of generating the subscription information and the target subscription information and the related content thereof are used as an invention point of the embodiment of the disclosure, and the technical problem mentioned in the background art is solved, namely, before the target software is upgraded, the verification on the security of the data source is often neglected easily, or the verification process is too complex, so that the security and the efficiency of the target software upgrading are low. The problem that the target software upgrade is low in safety or efficiency is often as follows: before the target software is upgraded, the verification on the security of the data source is easy to be ignored or the verification process is too complicated, so that the security and efficiency of the target software upgrade are low. If the problems are solved, the effect of improving the upgrading safety and efficiency of the target software can be achieved. To achieve this effect, the present disclosure obtains the subscription information by encrypting data from the SOC. Then, the target subscription information is obtained by reversely decrypting the subscription information. And finally, matching the target verification identifier group and the target software identifier group included in the target subscription information to complete verification of data source security. Thus, the safety of the target software upgrading can be improved. In addition, the encryption and decryption process combining cyclic shift and table lookup adopted by the method is shorter in time consumption compared with other complex security verification methods, and therefore the upgrading efficiency of the target software can be improved.

In some optional implementations of some embodiments, each atomic program upgrade information in the above atomic program upgrade information sequence may include an upgrade package identification, a flash start address, and a flash length. The flash start address may be a first physical address to be flashed. The length of the flash may be the number of consecutive physical addresses. The execution main body may perform flash processing on program storage partition data corresponding to each atomic program upgrade information in the atomic program upgrade information sequence. Specifically, the following steps can be performed:
the first step, based on the initial counter, for each atom program upgrade information in the atom program upgrade information sequence, executing the following substeps:
and a first substep of acquiring a target upgrade package based on the upgrade package identifier. The target upgrade package may be an upgrade package corresponding to the upgrade package identifier.

And secondly, receiving an upgrading program package corresponding to the upgrading program package identification. Wherein the upgrade package may be sent by the SOC.
And a second substep, performing a flash process on the program storage partition data corresponding to the atomic program upgrade information based on the target upgrade package, the flash start address and the flash length, and adding 1 to the value of the initial counter to obtain a target counter. The initial counter may be a counter with an initial value of 0. The target counter may be a counter whose initial value is 1.
Optionally, the executing body may further execute the following steps:
and step one, in response to the fact that the target upgrading program package is determined to be failed to be obtained, determining the value of the target counter as the number of the completed atomic program upgrading steps. The number of upgrading stages of the completed atomic program may be the number of upgraded atomic programs.
And secondly, generating a residual atomic program upgrading information sequence based on the completed atomic program upgrading number and the atomic program upgrading information sequence.

The above processing steps and related contents of the failure of obtaining the target upgrade package are used as an invention point of the embodiment of the present disclosure, and the technical problems mentioned in the background art are solved, namely, if the power failure or the network failure causes the data transmission to be interrupted, the control unit needs to erase the whole flash memory data again, receive the whole software upgrade package by taking the frame as a unit again, and perform the data writing operation on the whole flash memory by taking the frame as a unit, thereby causing the target software upgrade efficiency to be low. ". The problem that the upgrading efficiency of the target software is low is often as follows: if the data transmission is interrupted due to power failure or network disconnection, the control unit needs to erase the whole flash memory data again, receive the whole software upgrading program package by taking the frame as a unit again and perform data writing operation on the whole flash memory by taking the frame as a unit, thereby causing the target software upgrading efficiency to be lower. If the problems are solved, the effect of improving the upgrading efficiency of the target software can be achieved. In order to achieve this effect, the present disclosure may count each atomic upgrade program that has been upgraded through a counter, and determine each atomic upgrade program to be upgraded that remains. And then, performing flash processing on program storage partition data corresponding to each atom upgrading program to be upgraded to finish the upgrading of the target software. Thus, the target software upgrading efficiency can be improved.
The above embodiments of the present disclosure have the following advantages: by the target software upgrading method of some embodiments of the present disclosure, the efficiency of upgrading target software can be improved. Specifically, the reasons for the inefficiency of upgrading the target software are: with the increasing frequency of software upgrading and the increasing amount of flash memory data, the whole flash memory data is written in a flashing manner during each upgrading, which takes longer time, and leads to the lower efficiency of target software upgrading. Based on this, the target software upgrading method of some embodiments of the present disclosure first obtains a software identification information set. And updating each piece of software identification information in the software identification information set to the Ethernet. Therefore, the identification information of each software can be sent to the Ethernet, so that the subsequent system chip can select the target software for upgrading. Secondly, in response to receiving subscription information for at least one piece of software identification information in the software identification information set, a target software identification sequence is generated based on the received subscription information. Therefore, the software sequence to be upgraded selected by the demand side can be obtained. And finally, performing flash processing on the program storage partition data corresponding to each target software identifier in the target software identifier sequence so as to upgrade the target software. Therefore, the program storage partition data corresponding to each target software to be upgraded can be sequentially refreshed, time consumed for upgrading is shortened, and therefore the upgrading efficiency of the target software can be improved. Therefore, according to some target software upgrading methods disclosed by the disclosure, when software is upgraded every time, only the program storage partition data corresponding to each software to be upgraded needs to be refreshed, and the flash memory data of the whole piece does not need to be refreshed. Thus, the time consumed for upgrading is shortened. Further, the target software upgrading efficiency can be improved.
