It should be noted that the method provided by the present invention is not limited by the specific sequence shown in fig. 2 and the following, and the specific flow and steps of the system upgrade recovery method are described in detail below with reference to fig. 2.
Step S100, reading an upgrade log generated by the electronic equipment in the system upgrade process before power failure, and judging whether system upgrade is finished according to the upgrade log.
In this embodiment, the system of the electronic device includes five partitions: the electronic equipment comprises a uboot partition, a kernel partition, a file system partition, a configuration partition and an engineering partition, wherein in the system upgrading of the electronic equipment, the software upgrading comprises kernel partition upgrading and file system partition upgrading.
In this embodiment, the upgrade log is generated in the system upgrade process of the electronic device before power failure. Therefore, referring to fig. 3, in this embodiment, before step S100, the system upgrade recovering method further includes step S001 and step S002.
And S001, responding to system upgrading operation, sending a first upgrading request to an upgrading server, generating an upgrading log, and recording the first network configuration of the electronic equipment and the second network configuration of the upgrading server in the upgrading log.
In this embodiment, a first upgrade request may be sent to an upgrade server through a Web page logged in a browser, and the upgrade log may be generated in the project partition.
And S002, receiving a first-time upgrading file fed back by the upgrading server based on the first-time upgrading request, upgrading the system according to the first-time upgrading file, and recording the system upgrading state of the electronic equipment in the upgrading log.
In the embodiment, the received first upgrade file comprises a kernel image and a file system image, and the kernel image and the file system image can be stored in a memory space of the electronic device. Optionally, in this embodiment, version verification is further performed on the received kernel image and the received file system image to obtain version information of the kernel image and the file system image, and then the version information is recorded in the upgrade log. In order to verify the necessity of the system upgrade of the electronic device, optionally, in this embodiment, the obtained version information is further determined, if the version information meets a preset system upgrade requirement, step S002 is executed to perform system upgrade according to the first upgrade file, and record the system upgrade state of the electronic device in the upgrade log, and if the version information does not meet the preset system upgrade requirement, the system upgrade of the electronic device is stopped. The preset system upgrade requirement may be that the version number carried in the obtained version information is higher than the version number carried in the version information of the original system of the electronic device, where the original system of the electronic device is the current system of the electronic device before power failure.
In this embodiment, the system upgrade is a software upgrade, and includes updating a kernel partition of a system according to the kernel mirror, and updating a file system partition of the system according to the file system mirror. And the electronic equipment writes a first label representing the system upgrading start into the upgrading log before receiving the first upgrading file and upgrading the system according to the first upgrading file. Thereafter, as an embodiment, after the system upgrade is completed, a second tag characterizing the completion of the system upgrade is written into the upgrade log. In order to more clearly and specifically record the respective update states of the kernel partition and the file system partition in the system upgrade process before power failure so as to improve the system upgrade efficiency of the electronic device after power failure, as another embodiment, in the system upgrade process, after the kernel partition is updated, a third tag representing that the kernel partition is updated is written into the upgrade log, and after the file system partition is updated, a fourth tag representing that the file system partition is updated is written into the upgrade log. It should be noted that, in the system upgrade of the electronic device, the kernel partition is updated first, and the file system partition is updated later, so it can be understood that, here, if the upgrade log includes the fourth tag, it indicates that the system upgrade is completed.
Based on the above settings, in step S100, after the upgrade log is read, if the upgrade log includes the second tag or the fourth tag, it indicates that the system upgrade is completed, otherwise, it indicates that the system upgrade is not completed.
Step S200, if the system is not upgraded completely, establishing network connection with an upgrade server, and sending an upgrade recovery request to the upgrade server.
In this embodiment, if the system upgrade is not completed, the first network configuration of the electronic device and the second network configuration of the upgrade server are obtained according to the upgrade log, and further, a network connection with the upgrade server is established according to the first network configuration and the second network configuration.
Before power failure, if the system of the electronic device is upgraded and the implementation mode that the second tag is written to indicate that the system is upgraded is adopted, the upgrade recovery request is used for requesting to download the kernel image and the file system image.
Before the power failure, if the implementation mode that the fourth tag is written to indicate that the system upgrade of the electronic device is completed is adopted after the system upgrade of the electronic device is completed, the upgrade resuming request may be implemented by two substeps, i.e., step S210 and step S220, shown in fig. 4.
And step S210, acquiring the system upgrading state of the electronic equipment before power failure according to the upgrading log.
Optionally, in this embodiment, the system upgrade status of the electronic device may be represented according to a third tag and a fourth tag written in the upgrade log. Therefore, the obtaining of the system upgrade state of the electronic device is to read the third tag and the fourth tag from the upgrade log.
And step S220, generating a corresponding upgrade recovery request according to the system upgrade state.
Optionally, in this embodiment, the system upgrade state includes a first upgrade state representing that the updating of the kernel partition is not completed and the updating of the file system partition is not completed, and a second upgrade state representing that the updating of the kernel partition is completed and the updating of the file system partition is not completed. In implementation, the system upgrade state of the electronic device may be determined by reading and determining whether the upgrade log includes the third tag and the fourth tag. For example, when the upgrade log does not include the third tag and does not include the fourth tag, the system upgrade status is determined to be the first upgrade status, and when the upgrade log includes the third tag and does not include the fourth tag, the system upgrade status is determined to be the second upgrade status.
In this embodiment, the secondary upgrade file includes a kernel image and a file system image. The upgrade recovery request includes a first upgrade request and a second upgrade request. The first upgrade request corresponds to the first upgrade status, and is used for requesting to download the kernel image and the file system image. The second upgrade request corresponds to the second upgrade status, and is used for requesting to download the file system image. And if the system upgrading state is a first upgrading state, generating the first upgrading request, and if the system upgrading state is a second upgrading state, generating the second upgrading request. Therefore, the kernel mirror image can be prevented from being downloaded again under the condition that the system upgrading state is the second upgrading state, and the step of updating the kernel partition of the system of the electronic equipment which is completed before power failure is repeated, so that the system upgrading efficiency of the electronic equipment after power failure is effectively improved.
And step S300, receiving a secondary upgrade file fed back by the upgrade server based on the upgrade recovery request, and recovering system upgrade according to the secondary upgrade file.
If the received secondary upgrade file is a kernel image and a file system image, the system upgrade is restored according to the secondary upgrade file, including updating a kernel partition of a system according to the kernel image, and updating a file system partition of the system according to the file system image, so that the system of the electronic equipment is complete, and the electronic equipment can be started for use. If the received secondary upgrade file is a file system mirror image, the system upgrade is restored according to the secondary upgrade file, and the file system partition of the system is updated according to the file system mirror image, so that the system of the electronic equipment is completed, and the electronic equipment can be started for use.
Referring to fig. 5, in order to enable the electronic device to be quickly and automatically started for use without system upgrade after power failure, optionally, in this embodiment, the method for recovering system upgrade further includes step S400, step S500, and step S600.
And step S400, if the system upgrading is not finished, judging whether the system of the electronic equipment is in an available state according to the upgrading log.
In this embodiment, before power failure, the system upgrade stage includes a first upgrade file receiving stage and a system update stage. In view of this, the system upgrade stage of the electronic device before power failure may be determined according to the upgrade log, so as to determine whether the system of the electronic device is in an available state. In this embodiment, it is agreed that the system of the electronic device is in an available state if the system upgrade stage of the electronic device before power failure is in the first upgrade file receiving stage, and the system of the electronic device is not in an available state if the system upgrade stage of the electronic device before power failure is in the system update stage.
In implementation, the system upgrading stage of the electronic equipment before power failure is judged by judging whether the first label representing the system upgrading start exists in the upgrading log. For example, if the first tag does not exist in the upgrade log, it indicates that the system upgrade stage of the electronic device is in a first upgrade file receiving stage before the power failure, that is, it indicates that the system upgrade of the electronic device has not been initiated before the power failure, and thus, the system of the electronic device is in an available state if the original system of the electronic device is not damaged. If the first tag exists in the upgrade log, it indicates that the system upgrade stage of the electronic device is in a system update stage before power failure, that is, it indicates that the system upgrade of the electronic device has been initiated but not completed before power failure, so that the system of the electronic device is not in an available state if the original system of the electronic device is damaged.
And S500, if the system of the electronic equipment is in an available state, starting the electronic equipment to realize quick start and use of the electronic equipment after power failure.
Here, the electronic device is started based on the legacy system of the electronic device.
Step S600, if the system of the electronic device is not in an available state, executing step S200, establishing a network connection with an upgrade server, and sending a resume upgrade request to the upgrade server.
