It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for online upgrade of a device according to the present disclosure is shown. The online upgrading method of the equipment comprises the following steps:
In this embodiment, an execution main body of the device online upgrade method (for example, the terminal device shown in fig. 1) may acquire the version to be upgraded from the server in a wired connection manner or a wireless connection manner, and download the version into the memory. In order to prevent upgrading failure caused by power failure in the upgrading process, the version to be upgraded can be backed up to obtain a first mirror image, and the first mirror image is stored in a mirror image storage partition of the flash. Data in the mirror image storage partition of the flash cannot be lost when power is lost. When the flash is powered on, the backup version can be obtained from the mirror image storage partition of the flash again, and the upgrading is carried out again. The mirror image storage partition of the flash can keep the mirror images of two versions, an original version and a version to be upgraded. If two versions already exist before, the oldest version can be overwritten with the version to be upgraded.
In this embodiment, the upgrade state is saved in the communication partition on the flash. The method of the present disclosure maintains four states: start of burning (burn start), success of burning (burn ok), boot (boot), and success of upgrade (boot). The version upgrading process comprises two stages: a burning stage and a starting stage. The burn start (burn start) and the burn ok (burn ok) are used to record the status of the burn stage. If the power is lost in the burning stage, the state is still burning start when the power is powered on again, and burning needs to be repeated. Boot (boot) and upgrade success (bootOK) are used to record the state of the boot phase.
In this embodiment, if the recording process is completed without an accident, the upgrade status is changed to recording success. Therefore, even if the subsequent process fails due to power failure, the recording operation does not need to be re-recorded. And restarting the system after the burning is successful, wherein the BIOS system is started.
In this embodiment, the upgrade status is detected after startup. Detection is initiated by the bootstrap program (e.g., uboot). The boot program will detect the upgrade status each time it is powered on. And judging whether to re-burn or restart according to the upgrading state.
And step 205, if the upgrade state is recording success or upgrading success, setting the upgrade state as start and guiding the embedded software system to start.
In this embodiment, if the upgrade status is recording success or upgrading success, it indicates that recording does not need to be resumed, and only the embedded software system needs to be booted. The current upgrading state is recorded as the starting state before the embedded software system is started so as to prevent power failure in the starting process of the embedded software system, and the stage of the upgrading process can be judged according to the upgrading state. And loading the data of the system partition of the flash into a memory in the starting process of the embedded software system, jumping to the forefront of the memory, starting to enter the system starting, and starting various applications.
In the embodiment, whether the startup is successful is detected by reading the environment variable in the communication partition of the flash.
And step 207, if the starting is successful, finishing the upgrading, and setting the upgrading state as successful upgrading.
In this embodiment, if the start is successful, it indicates that the version upgrade is successful, and the upgrade is ended. And modifying the upgrading state into upgrading success. If a power loss occurs thereafter, the upgrade process is not re-entered. If the watchdog timer is set, it needs to be cleared to avoid device restart.
And step 208, if the upgrading state is starting or burning is started, burning the first mirror image into the system partition of the flash.
In this embodiment, if it is detected that the upgrade status is the start or the start of burning after power-on, it indicates that the last upgrade is unsuccessful and the upgrade needs to be performed again. And acquiring the backed-up first mirror image from the mirror image storage partition of the flash, and burning the first mirror image into the system partition of the flash.
In this embodiment, after the re-burning is successful, the upgrade status needs to be modified to be the successful burning, so that the situation that the upgrade status cannot be recovered when the power is lost in the re-burning process can be avoided. After the recording is successful, it means that the recording stage is finished, and the system is started to enter the start stage, and step 205 and step 207 are continuously executed.
According to the method provided by the embodiment of the disclosure, the system upgrade is divided into different upgrade states according to the time sequence, the system is judged to be abnormal through the management of the different upgrade states of the system, and the corresponding system repair strategy is adopted, so that the problems of power interruption, system damage and the like of a user in the system upgrade process are solved. And detecting the starting problem of the system mirror image through the boot and boot OK mark judgment of the system in the starting stage, and automatically burning and repairing the system mirror image through a bootstrap program.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the device online upgrade method according to the present embodiment. In the application scenario of fig. 3, the terminal device downloads the upgrade package from the server and backs up the upgrade package to a system partition of a flash that does not lose data even if power is lost. Before burning, the upgrading state is set to burn start, and then the burning of the upgrading package is started. If the power is cut off in the burning process, the upgrading state is detected firstly after the power is powered on again. And if the upgrade state is detected to be burn start, acquiring the backup upgrade package from the system partition of the flash, and restarting burning. If the burning is successful, the upgrading state is converted into burn OK, and the upgrading package is used for starting the equipment, so that the upgrading state is modified into boot. If the power is lost in the starting process, the upgrading state is detected firstly after the power is re-electrified, and if the upgrading state is detected to be boot, the backup upgrading packet is obtained from the system partition of the flash, and burning is restarted. If the burning is successful, the upgrading state is converted into burn OK, the upgrading package is used for starting the equipment, and the upgrading state is modified into boot. If the starting is finished without power failure in the starting process, the upgrading is finished, and the upgrading state is set to bootOK. If power failure occurs again, the upgrading state is detected firstly after power is powered on again, if the upgrading state is detected to be bootOK, the last upgrading is successful, the upgrading is not performed, only the system starting process is completed, the upgrading state is set to boot before starting, and the upgrading state is modified to bootOK after the starting is successful.
With further reference to FIG. 4, a flow 400 of yet another embodiment of a device online upgrade method is shown. The process 400 of the online upgrade method for the device includes the following steps:
In this embodiment, an execution main body (for example, the terminal device shown in fig. 1) of the device online upgrade method may back up an original version to obtain a second mirror image. And storing the second image to the image storage partition of the flash. The mirror image storage partition of the flash can keep two versions of mirror images, an original version (namely the currently used version) and a version to be upgraded.
Step 402, if the number of failed start-up times exceeds a predetermined threshold, setting the upgrade state as start of burning, and burning the second mirror image to the system partition of the flash.
In this embodiment, the number of times of start failure is counted during the upgrade process using the version to be upgraded. If the number of failed start-up times exceeds a preset threshold, the version to be upgraded has a problem and cannot be used. Thus requiring a fallback to the original version. This step is substantially the same as step 202, except that the step is to burn the image of the original version into the system partition of the flash.
In this embodiment, if the recording process is completed without an accident, the upgrade status is changed to recording success. Therefore, even if the subsequent process fails due to power failure, the recording operation does not need to be re-recorded. And restarting the system after the burning is successful, wherein the BIOS system is started.
And 405, if the upgrading state is recording success or upgrading success, setting the upgrading state as starting and guiding the embedded software system to start.
And step 408, if the upgrading state is starting or burning is started, burning the second mirror image into the system partition of the flash.
In this embodiment, if it is detected that the upgrade status is the start or the start of burning after power-on, it indicates that the last upgrade is unsuccessful and the upgrade needs to be performed again. And if the starting failure times exceed a preset threshold value, acquiring a second mirror image which is well backed up from a mirror image storage partition of the flash, and burning the second mirror image into a system partition of the flash. Otherwise, obtaining the first mirror image which is well backed up from the mirror image storage partition of the flash, and burning the first mirror image into the system partition of the flash.
And 409, if the second mirror image is completely burned, setting the upgrading state as successful burning, and starting the system.
In this embodiment, after the re-burning is successful, the upgrade status needs to be modified to be the successful burning, so that the situation that the upgrade status cannot be recovered when the power is lost in the re-burning process can be avoided. After the recording is successful, it means that the recording stage is finished, and the system is started to enter the start stage, and step 405 and step 407 are continuously executed.
As can be seen from fig. 4, compared with the embodiment corresponding to fig. 2, the flow 400 of the device online upgrade method in this embodiment represents a step of rollback of version upgrade failure. Therefore, the scheme described in the embodiment can be used for dealing with various unexpected situations, and the situation that the equipment cannot be used due to upgrade failure is avoided.
