Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of a software boot and upgrade failure rollback method according to an embodiment of the present invention.
As shown in fig. 1, a software boot and upgrade failure rollback method according to an embodiment of the present invention may include the following steps:
and S1, acquiring the initial identification of the equipment when the equipment is started when the equipment is powered on.
And S2, judging whether the initial mark is changed.
And S3, when the initial mark is not changed, the control device is reset and records the starting times.
And S4, when the starting times are more than the first preset times, restoring the application program in the factory file backup area to the execution file storage area so as to enable the equipment to normally operate. The first preset times can be calibrated according to actual conditions.
Specifically, as shown in fig. 2, the general storage area of the device is generally divided into a flag information area a, an execution file storage area B, a file backup area C, and an undecapsulated file storage area D. The mark information area a records some identifiers, such as whether new software is downloaded or not, and what version of software is currently running; the execution file storage area B is an area for storing the currently applied software, and the software in the area is operated by default after the equipment is powered on; the file backup area C is used for backing up the software to be overwritten and executed or the software in the backup storage area B.
Generally, upgrade failure occurs in a situation where an original program is covered, but the existing upgrade program does not work normally, and in this situation, the original program is backed up before upgrade, and related information is built in the flag area a. When the new version software can not work normally, the original program is covered to the area B after the equipment is reset, and then the original program is operated according to the original starting. At this time, if the contents of the backup execution file storage region B fail, the device may not operate normally. Therefore, as shown in fig. 3, a factory file backup area F may be added to store a factory backup program, and when the application program copied to the file backup area C cannot be used, the application program in the factory file backup area F is restored to the execution file storage area, so that the device operates normally.
Specifically, a small number of addresses are reserved in the highest address part in the RAM address area and used for recording the device starting initial value identification and starting a device hardware watchdog at the same time. When the application program is successfully started, a hardware watchdog is fed to prevent hardware reset caused by timeout of the watchdog, the device starting initial value identification in the RAM is changed, meanwhile, the related identification in the storage area A is changed to indicate that the software of the version can normally run, and the subsequent reset can know that the software of the version can normally start when started. If the application program is not normally started, the initialization identification value at the corresponding RAM is not changed, and the hardware watchdog is not fed in time, so that the overtime equipment is reset. After the reset is started, the program finds that the corresponding identifiers (the identifier in the RAM and the identifier in the storage area A) are not changed, and records the accumulation times. When the operation times reach a certain number and the equipment is still not normally started, the application program in the factory file backup area is restored to the execution file storage area, so that the equipment normally runs.
According to an embodiment of the present invention, the software start-up and upgrade failure rollback method further includes: and when the initial identifier is not changed and the starting times are greater than a second preset time, restoring the application program in the file backup area to the execution file storage area so as to enable the equipment to normally operate, wherein the second preset time is less than the first preset time and can be calibrated according to actual conditions.
That is to say, after the device is upgraded, the application program is started, if the application program cannot be started normally, the hardware watchdog is not fed in time, so that the overtime device is reset, at this time, the initial identifier is not changed, the starting times are recorded, the upgraded application program is started again, when the starting times exceed the second preset times, the upgraded version of the application program is abnormal, and the application program in the file backup area is restored to the execution file storage area, so that the device can operate normally.
After the application program in the file backup area is restored to the execution file storage area, the initial identification of the equipment during starting is continuously obtained, whether the initial identification changes or not is judged, if the application program cannot be started normally, the hardware watchdog is not timely fed to cause the overtime equipment to reset, the initial identification does not change at the moment, the application program backed up in the file backup area is possibly abnormal, the equipment is reset at the moment, the starting times are recorded, the upgraded application program is started again, when the starting times exceed the first preset times, the application program backed up in the file backup area is abnormal, and the application program in the outgoing file backup area is restored to the execution file storage area so that the equipment can run normally.
It should be noted that the first preset number of times at this time is the number of times of starting counting from the occurrence of an exception to the upgraded software. That is, when the initial identifier is not changed, the process of restoring the application program in the file backup area to the execution file storage area is performed first, and if the initial identifier is not changed yet, the process of restoring the application program in the factory file backup area to the execution file storage area is performed. The first predetermined number is therefore the total number of starts.
According to an embodiment of the present invention, the software start-up and upgrade failure rollback method further includes: backing up the application program in the execution file storage area to a file backup area; and decompressing the application program in the non-decapsulated file storage area to the decapsulated file storage area, and copying the application program to the execution file storage area to complete application program upgrading.
Specifically, when the storage area has sufficient capacity and the decapsulated file storage area E is increased, the software of the original version does not need to be covered when the decapsulated and upgraded file is performed, the storage area may have software of three versions (a factory version, an existing version and a version to be upgraded), and then when the version is required to be rolled back, various options are available. For example, when an upgrade package exists, the original program is backed up to the file backup area C, the upgrade file is decapsulated to the decapsulated file storage area E, and the decapsulated file is copied to the executable file storage area B, so that three different versions are included, that is, a factory version exists in the factory file backup area F, an existing version exists in the file backup area C, and an upgrade book needs to be updated in the execution file storage area B. The advantage of adding the decapsulated file storage area E is that after decapsulation, the version to be upgraded after decapsulation can be verified, and the risk of application program upgrade failure is reduced.
According to another embodiment of the present invention, the software startup and upgrade failure rollback method further includes: backing up the application program in the execution file storage area to a file backup area; and decompressing the application program in the undecapsulated file storage area to an execution file storage area to complete application program upgrading.
That is, when the decapsulated file storage area E is not added, the application program is upgraded by backing up the application program in the execution file storage area to the file backup area and then copying the decompressed application program to the execution file storage area to complete the upgrade of the application program.
It should be noted that, regardless of the upgrade of the application program or the rollback mode of the application program, after the upgrade of the application program or the rollback mode of the application program is completed, a related start identifier needs to be set, so that when the device is started next time, the corresponding identifier is directly started.
In summary, according to the software start and upgrade failure rollback method of the present invention, when the device is powered on and started, an initial identifier of the device during start is obtained; when an application program is started, judging whether an initial identifier changes, and when the initial identifier does not change, controlling equipment to reset and recording starting times; when the starting times are larger than the first preset times, the application program in the factory file backup area is restored to the execution file storage area, so that the equipment can normally operate, and the normal work of the equipment can be ensured when the application program is updated to be abnormal.
