It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
The invention will be further explained by the description of the embodiments with reference to the drawings.
The embodiment provides a system upgrade method, which is applied to a terminal device, where the terminal device is configured with first system data and second system data, as shown in fig. 1, the method includes:
s100, reading data header information of target system data, wherein the target system data is first system data or second system data.
Specifically, the system data is stored in advance in emmc (embedded multimediacard), nand flash and other storage devices, which can be read and written without losing power-down data, so as to ensure that the data system data is not lost and can be updated or modified.
In this embodiment, the data header information of the preset system data is read by a boot loader, where the boot loader is a first section of code executed by the embedded system after power-up, and after the boot loader completes initialization of the CPU and related hardware, the boot loader loads an operating system image or a cured embedded application program into the memory and then jumps to a space where the operating system is located, so as to start the operating system to run.
In this embodiment, the system data burned in the terminal device includes two sets of system data, the two sets of system data are completely consistent during initialization, and subsequent system operation or update is performed on the basis of the two sets of system data. If the data of one part is incomplete due to update failure, the system can also operate by using the data of the other part, and update or repair the incomplete data. That is, when the system is booted up at any one time, the data of the two operating systems may be consistent or different, and optionally, one of the operating systems is updated in version compared with the other operating system.
In this embodiment, the target system data is preconfigured with an identifier, that is, the first system data and the second system data are both configured with identifiers, and the identifier may change correspondingly with each upgrade, and in practical applications, the identifier includes an update identifier and a load identifier (the update identifier may be 1, and the load identifier may be 2).
And S200, verifying the integrity of the data header information.
In this embodiment, the first system data and the second system data are stored in different areas, specifically, the first system data is stored in a first storage area, and the second system data is stored in a second storage area. Each system data includes a data header of the data, a Bootloader and other data of the system. When reading the header information of two pieces of data, the Bootloader needs to obtain the header information from different areas. It should be noted that the header information of the first system and the second system is stored in the third storage area, so that the Bootloader can directly obtain the header information of the two pieces of data from the third storage area when reading the header information of the two pieces of data. It should be noted that, when the system data to be updated is updated, the header information of the system data to be updated is also changed accordingly. The invention also ensures the stability of the upgrading process by verifying the integrity of the data header information.
S300, selecting system data to be updated from the first system data and the second system data according to the integrity, and upgrading the system data to be updated.
In this embodiment, the situation that both the system data are incomplete does not occur. Therefore, when one system data is incomplete, the system can be loaded by the other system data, and the stability of the upgrading process is guaranteed.
In an implementation manner of this embodiment, the selecting, according to the integrity, system data to be updated from the first system data and the second system data, and upgrading the system data to be updated specifically includes:
s301, selecting system data to be updated from the first system data and the second system data according to the integrity;
s302, obtaining upgrading data corresponding to the system data to be updated, and upgrading the system data to be updated based on the obtained upgrading data.
In this embodiment, the upgrading method of the system is performed by OTA, and in practical application, the terminal device sends a request to the server to obtain upgrading data corresponding to the current system (system data to be updated), and then upgrades the system data to be updated according to the obtained upgrading data. Therefore, the embodiment of the invention upgrades in a differential mode, only the differential part of data is needed to be upgraded, but not the whole data to be updated, so that the quick upgrade can be realized, and meanwhile, the influence of the erasing chip on the service life of the single equipment is also reduced.
Further, when the mark corresponding to the read target system data is an update mark, the target system data corresponding to the update mark is system data to be updated. It should be noted that, after the update and upgrade are completed, the identifier corresponding to the target system data is modified into a loading identifier.
Further, the identifier of the data to be updated is the address of the storage area of the system data, for example, when the system data to be updated is the first system data, and the storage area is the first storage area, the address of the first storage area is directly sent to the processor, and the processor can find the system data that needs to be updated according to the address.
In practical application, before selecting the system data to be updated from the first system data and the second system data according to the integrity and upgrading the system data to be updated, the method further includes: and selecting system data to be loaded from the first system data and the second system data according to the integrity, and loading the system data to be loaded to start the system.
In this embodiment, the current boot mode may be determined by Bootloader, where the boot mode includes two types, one type is a boot mode, that is, a normal boot operation of the device. The other is an upgrade mode, i.e., a mode in which the system restarts after the system data is updated. In this embodiment, Bootloader may determine which mode is currently through system history information.
Further, if the current starting mode is the upgrading mode, the identifier of the data to be updated is sent to a processor of the system, and the processor finishes upgrading the data of the system to be updated.
In this embodiment, the identifier of the system data to be updated may be A, B or other letters or other symbols with identifiers, and after receiving the identifier, the processor can determine which system data needs to be updated according to the correspondence between the pre-stored identifier and the data, and then perform the update operation.
And when the upgrading is successful, restarting the system, so that the system executes the steps again, and loading the upgraded system data to realize the upgrading of the system.
