It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It is to be further noted that, for the convenience of description, only a part of the structure relating to the present invention is shown in the drawings, not the whole structure.
Example one
Fig. 1 is a schematic flow chart of a software upgrading method according to an embodiment of the present invention, where the method is applicable to upgrading software of a vehicle-mounted platform, and the method may be executed by a software upgrading apparatus. As shown in fig. 1, the method specifically includes the following steps:
The third party can send a software upgrading request to a vehicle-mounted system at any time according to the setting of a worker, the third party can be an upper computer or a computer and other equipment, the vehicle-mounted system can be a VxWorks (WickWa) system, the VxWorks is a real-time operating system, and the VxWorks system is installed on a server and can be used for executing the upgrading process of software. The third party can send a software upgrading request to the server at regular time according to the requirement, and the software upgrading request can include information such as a name and a version identification of software to be upgraded. The server receives a software upgrading request, specifically, the VxWorks system receives the software upgrading request, determines target software to be upgraded according to information in the software upgrading request, and judges whether the target software needs to be upgraded.
In this embodiment, optionally, determining the target software to be upgraded according to the received software upgrading request, and determining whether to upgrade the target software, including: determining target software and a target version to be upgraded according to a received software upgrading request of a third party; acquiring a current version of target software, and comparing the current version with the target version; and if the current version is inconsistent with the target version, determining to upgrade the target software.
Specifically, the software upgrading request is sent to the server of the vehicle-mounted platform by the third party, for example, the software upgrading request may be sent every 24 hours. After the VxWorks system in the server receives the software upgrading request, the information contained in the software upgrading request is obtained, and the target software to be upgraded and the target version to be upgraded are determined. For example, the software upgrade request may include information such as a request transmission time, a version identification, and a software name. After the target software is determined, the current version of the target software is checked, and the current version and the target version are compared. And determining whether the current version is the target version, and if not, determining that the target software needs to be upgraded. The beneficial effect of setting like this lies in, can confirm whether need to upgrade to target software fast, avoid the repeated upgrading, practice thrift the upgrade time, effectively improve upgrading efficiency.
In this embodiment, optionally, after determining target software to be upgraded according to the received software upgrade request and determining whether to perform software upgrade on the target software, the method further includes: if the target software is determined to be upgraded, sending a feedback message agreeing to the upgrade to the third party, so that the third party receives the feedback message agreeing to the upgrade and sends a software upgrading compressed packet; if the target software is determined not to be upgraded, sending a feedback message for stopping upgrading to the third party, and ending the upgrading process of the target software.
Specifically, if the current version is determined to be inconsistent with the target version, it is determined that software upgrading needs to be performed on the target software, and a feedback message agreeing to the upgrading is sent to the third party by the server, specifically, the feedback message agreeing to the upgrading is sent to the third party by the VxWorks system. And after receiving the feedback message agreeing to upgrade, the third party sends a software upgrading compression packet to the VxWorks system for the system to upgrade the software. And if the current version is consistent with the target version, determining that software upgrading is not required to be carried out on the target software, sending a feedback message for stopping upgrading to a third party by the VxWorks system, and ending the upgrading process of the target software. The VxWorks system can not send the feedback message to the third party, or the third party fails to receive the feedback message, and still sends the software upgrading compressed packet under the condition that the current version is consistent with the target version, and the VxWorks system can reject the message and end the upgrading process of the target software. The beneficial effect of setting like this is, through to the third party feedback, realize with the data interaction of third party, avoid the third party to send the compression package under the condition that does not need the upgrading, reduce the work load of third party, improve the efficiency of software upgrading.
And 120, if so, receiving the software upgrading compression package, and storing the software upgrading compression package to an operation area for storing the firmware.
The storage firmware is divided into an operating area and an upgrading area, the operating area is used for operating software, the upgrading area is used for upgrading the software, for example, the storage firmware is 10G, the operating area is divided into 5G, and the upgrading area is divided into 5G. If the target software is determined to be subjected to software upgrading, the software upgrading compression package is received from a third party, and the target software is not yet upgraded, so that the software upgrading compression package needs to be stored in the operation area.
And step 130, decompressing the software upgrading compression packet to an upgrading area for storing the firmware to obtain software upgrading data, and upgrading the target software according to the software upgrading data.
The software upgrading compression package is compressed by a third party according to a preset compression algorithm, after the VxWorks system receives the software upgrading compression package, the software upgrading compression package is decompressed into an upgrading area according to a corresponding decompression algorithm, and decompressed data are software upgrading data. And the VxWorks system updates the target software in the updating area according to the software upgrading data.
In this embodiment, optionally, decompressing the software upgrade compressed packet to an upgrade area storing the firmware to obtain software upgrade data, and upgrading the target software according to the software upgrade data, including: according to a preset decompression algorithm, releasing the software upgrading compression packet in the operation area into an upgrading area for storing firmware to obtain software upgrading data; verifying the directory file of the software upgrading data according to a preset data verification algorithm; and if the verification is successful, upgrading the target software according to the software upgrading data.
Specifically, a decompression algorithm corresponding to the third-party compression algorithm is stored in the VxWorks system in advance, and the software upgrading compression packet can be decompressed. After the software upgrading compression package is obtained, the software upgrading compression package is decompressed according to a preset decompression algorithm, the software upgrading compression package is released from the operation area to the upgrading area, and decompressed software upgrading data are stored in the upgrading area. After the software upgrading data are obtained, the software upgrading data are verified according to a preset data verification algorithm, and a directory file of the software upgrading data can be verified. For example, the format of the directory file and other information may be checked, and a standard format may be set in the preset data checking algorithm. And determining whether the software upgrading data has the problems of non-standard format or abnormal data and the like according to a data verification algorithm, if not, determining that the software upgrading data is verified successfully, and upgrading the target software according to the software upgrading data. If the verification is unsuccessful, determining that errors exist in the software upgrading data, namely errors exist in the software upgrading compressed packet, sending a data error message to a third party through a network, and prompting the third party to resend the software upgrading compressed packet, wherein the target software is failed to be upgraded. The beneficial effect that sets up like this lies in, will compress the package and release to the upgrading region, make the operation region distinguish with the upgrading region, and in the prior art, the storage firmware is in the operation state or is in the upgrading state either, and when software upgrading, can't carry out the operation of software, and causes data loss easily in the upgrading process. By dividing different areas, the software can be normally operated in the operation area while being upgraded, the data is prevented from being lost during upgrading, the probability of upgrading failure is reduced, and the software upgrading efficiency is improved.
And 140, if the target software is upgraded, taking the upgrading area as a new operation area, and operating the target software in the new operation area.
The upgrading region is upgraded according to the software upgrading data, after upgrading is finished, the roles of the upgrading region and the running region are exchanged, the upgrading region serves as a new running region to run upgraded software, and the running region serves as a new upgrading region to wait for next upgrading. The running area is used as a new upgrading area, and the software upgrading compression package in the running area can also be used as a backup.
In this embodiment, optionally, if the target software is upgraded, taking the upgrade area as a new operation area, and operating the target software in the new operation area, includes: if the target software is upgraded, triggering a preset self-starting request, and carrying out self-starting within preset time; checking whether the target software meets the preset software self-checking requirement; if yes, determining that the target software is successfully upgraded, writing an upgrade success identifier into the operation area, and feeding back an upgrade success message to a third party; and in response to a system restart instruction, taking the upgrading area as a new operation area, taking the operation area as a new upgrading area, and operating the target software in the new operation area.
Specifically, if the upgrading process in the upgrading area is finished, a preset self-starting request is triggered. The triggering condition of the self-starting request is that the upgrading is finished, and the self-starting refers to self-starting of the VxWorks system. The self-starting may be performed within a preset time after the target software upgrade is finished, for example, in response to a successful target software upgrade, the self-starting may be performed after one minute of the upgrade completion. After the self-starting is finished, the VxWorks system checks the target software according to the preset software self-checking requirement, and judges whether the target software meets the preset software self-checking requirement or not. For example, the software self-test requirements may include requirements for network functions and requirements for communication of the target software, and the like. And if the target software meets the preset software self-checking requirement, determining that the upgrading operation of the upgrading region is successful, writing the successfully upgraded mark into the operation region, and feeding back a successfully upgraded message to a third party. After the third party receives the message of successful upgrade, a worker can send a VxWorks system restart instruction to the server. And after a restart instruction is received, restarting the VxWorks system, taking the upgrading area as a new operation area and taking the operation area as a new upgrading area after restarting, and enabling the target software to operate in the operation area. After the software is restarted, a U-Boot (Universal Boot Loader) in the server reads an upgrading mark in the running area, if the upgrading mark is an upgrading success mark, the target software is finally determined to be upgraded, and the upgrading area is used as a new running area to start the target software. The self-checking method has the advantages that the self-checking is carried out on the target software after the self-starting, the target software is guaranteed to be free of problems in upgrading, and the software upgrading accuracy is improved. After the system is restarted, the identities of the operating area and the upgrading area are exchanged, so that the flexibility of dividing each area in the stored firmware is realized, the upgrading area can be directly used as the operating area to operate the target software after being upgraded, the loss phenomenon generated in data transmission is reduced, and the reliability and the efficiency of software upgrading are improved.
In this embodiment, optionally, after checking whether the target software meets the preset software self-test requirement, the method further includes: and if the target software does not meet the preset software self-checking requirement, determining that the target software fails to be upgraded, writing an upgrade failure identifier into the operation area, and feeding back an upgrade failure message to a third party.
Specifically, if the target software does not meet the preset software self-checking requirement, it is determined that the target software is failed to be upgraded, and an upgrade failure identifier is written into the operation area. The running area can be pre-stored with an upgrading failure identifier, and if the target software is upgraded successfully, the upgrading failure identifier is written in to cover the upgrading failure identifier; if the target software fails to be upgraded, any mark is not written into the running area, and the original upgrading failure mark is reserved. If the target software self-check is determined not to meet the requirements, a third party can feed back a message of failed upgrade, and record an upgrade log. The third party may not send a system restart instruction to the server, and the upgrade process is finished. And the third party can also continuously send a system restart instruction, the U-Boot reads the upgrading mark in the operating area, the upgrading mark is an upgrading failure mark, the upgrading failure of the target software is determined, and the identities of the operating area and the upgrading area are not required to be exchanged. The beneficial effect of setting like this lies in, can in time feed back the upgrading result to the third party, through setting up the upgrading sign, can avoid continuing to upgrade the target software when upgrading the failure, effectively improve the efficiency of software upgrading and operation.
According to the technical scheme, the storage firmware is divided into the operation area and the upgrading area, the operation area stores the software upgrading compression package, the upgrading area is upgraded according to the software upgrading compression package, after upgrading is finished, the roles of the upgrading area and the operation area are exchanged, the upgrading area serves as a new operation area to operate the software, and the original operation area serves as a new upgrading area to wait for next upgrading. The problem that the whole storage firmware can only be in one state of upgrading or running during upgrading or running in the prior art is solved, the upgrading area and the running area cannot be in the running state at the same time, and data loss during running is avoided. And by dividing different areas, the division of the function of the storage firmware is realized, and the efficiency of software upgrading is effectively improved.
