Description

OTA (over the air) upgrading method, electronic equipment and chip system

Technical Field

The application relates to the technical field of terminals, in particular to an OTA upgrading method, electronic equipment and a chip system.

Background

The internal Memory space of the electronic device includes a ROM space (Read only Memory) and a user space. The user space refers to a storage area for storing user data, and the ROM space refers to a storage area for storing firmware code (also referred to as an operating system) of the electronic device. The ROM space of an electronic device is determined by the size occupied by the operating system. When the ROM space required by the new version of the operating system is enlarged relative to the ROM space required by the old version of the operating system, it may result in that the OTA (Over-the-air technology, Over-the-air on-line upgrade technology or Over-the-air download technology) upgrade of the operating system of the electronic device cannot be completed.

In order to ensure that the operating system of the electronic equipment can still be upgraded OTA after the ROM space required by the new version operating system is expanded, when the size of the partition of the electronic equipment is set, a redundant space which cannot be used by a user is reserved in each partition. For part of electronic devices, the redundant space of each partition can even reach about 5g (gigabyte). Such a large redundant space may result in an inefficient use of the storage space of the electronic device.

Disclosure of Invention

The application provides an OTA upgrading method, electronic equipment and a chip system, which can improve the utilization rate of an internal storage space of the electronic equipment, can ensure that user data cannot be lost, and does not need to adjust the whole user space.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, an OTA upgrading method is provided, including: when detecting that OTA upgrading needs to be carried out on an operating system of the electronic equipment, acquiring a target ROM space required by a new version operating system; if the target ROM space is larger than a first ROM space of the electronic equipment, applying for a first storage space from a user space of the electronic equipment, wherein the first storage space is an area which does not store user data in the user space, and the first ROM space is a ROM space which is used for storing an operating system in an internal storage space of the electronic equipment before OTA upgrade is carried out on the operating system of the electronic equipment; merging the first ROM space and the first storage space as a second ROM space of the electronic device; and performing OTA upgrade on the operating system of the electronic equipment based on the second ROM space.

According to the embodiment of the application, when OTA upgrading needs to be carried out on the operating system of the electronic equipment, the ROM space needed by the new version operating system is determined. And if the ROM space required by the new version of operating system is larger than the first ROM space of the electronic equipment, applying for the first storage space from the user space of the electronic equipment. The first ROM space and the first memory space are then merged as a second ROM space for the electronic device. And when the operation information of the electronic equipment needs to be upgraded by OTA, using the second ROM space to upgrade by OTA.

The OTA upgrading method can improve the utilization rate of the internal storage space of the electronic equipment and can ensure that user data cannot be lost, which is equivalent to the related technology I and the related technology II. Compared with the third related art, the first storage space is an area in the user space where the user data is not stored, and the whole user space does not need to be adjusted, so that the situation that the time required by the adjustment process of the user space is long and the user cannot use the electronic device for a long time does not occur.

In combination with the first aspect, in some embodiments, the method further includes: and determining the first storage space according to the difference value of the target ROM space and the first ROM space.

After obtaining the target ROM space required by the new version of the operating system, the target ROM space required by the new version of the operating system may be compared with the first ROM space. If the target ROM space required by the new version of the operating system is larger than the first ROM space of the electronic device, the first ROM space cannot store the new version of the operating system. That is, OTA upgrade of the operating system of the electronic device is not possible based on the first ROM space.

At this time, the first storage space may be applied from the user space of the electronic device, and information of the first storage space may be recorded. The first storage space is an area which does not store user data in the user space, and the size of the first storage space is determined according to a difference value between a target ROM space and the first ROM space, wherein the target ROM space is required by a new version of the operating system. For example, if the target ROM space required by the new version of the operating system is a and the first ROM space is b, the first storage space should be greater than or equal to the difference a-b between the target ROM space and the first ROM space.

With reference to the first aspect, in some embodiments, after applying for the first storage space from the user space of the electronic device, the method further includes: and storing the information of the first storage space, wherein the information of the first storage space comprises the position and the size of the first storage space.

For example, the start position and size of the first storage space may be saved to a preset position. The position of the first storage space is the absolute position of the first storage space in the user space, so that the position and the size of the first storage space can still be found after the user file system is damaged.

With reference to the first aspect, in some embodiments, the method further includes moving the first storage space to a front-most end of the partition of the user space; and modifying the initial position of the partition of the user space, and moving the first storage space out of the partition of the user space.

For example, the first storage space is moved to the foremost end of the partition of the user space, and then the start address of the partition of the user space may be modified, and the first storage space is moved out of the partition of the user space, so as to obtain a new partition of the user space. For example, after the first storage space is moved to the front end of the partition of the user space, the starting position of the first storage space is x ₁ (is the starting position of the partition of the user space) and the ending position is x ₂ Then, the first storage space is moved out of the partition of the user space, and the starting position of the partition of the new user space is obtained as x ₂ The next position of (a).

Wherein the first storage space may be moved to a frontmost end of the partition of the user space after an OTA upgrade of an operating system of the electronic device based on the second ROM space. Or, after applying for a first storage space from a user space of the electronic device, move the first storage space to a forefront of a partition of the user space, which is not limited in this embodiment of the present application.

In this embodiment, the first storage space is moved to the forefront of the partition of the user space. And then, modifying the initial position of the partition of the user space, and moving the first storage space out of the partition of the user space. Since the first storage space is moved out of the partition of the user space, the data of the new version of the operating system is not deleted if the data in the user space needs to be cleaned up.

Optionally, before moving the first storage space to the foremost end of the partition of the user space, the method may further include: and backing up the data in the first storage space, so that the data loss of the first storage space in the moving process can be prevented. If the data in the first storage space is lost in the moving process, the backed-up data can be copied to the moved first storage space.

In one scenario, after detecting a preset operation, the first storage space may be moved to the forefront of the partition of the user space, the start position of the partition of the user space is modified, and the first storage space is moved out of the partition of the user space.

Illustratively, the preset operation may be an operation of deleting data in the user space. For example, the preset operation may be an operation of restoring factory settings of the electronic device.

By way of example, the first storage space may be an area having a preset identifier in the user space partition. The electronic device may detect whether the partition of the user space includes an area with a preset identifier, so as to determine whether the first storage space exists in the partition of the user space of the electronic device.

It can be understood that restoring factory settings to the electronic device deletes data in the partition of the user space. Because the first storage space is still located in the user space, if factory settings are restored to the electronic device at this time, data in the first storage space is deleted. And the first storage space stores part of data of the new version operating system, so that factory reset cannot be directly executed on the electronic device, and the data in the first storage space needs to be prevented from being deleted. Based on the above, the first storage space can be moved to the foremost end of the partition of the user space, and the start address of the partition of the user space is correspondingly modified, so that the new partition of the user space does not contain the first storage space.

For example, after detecting a preset operation, determining whether the first storage space is located at the forefront of the partition of the user space according to the starting position of the first storage space; and if the first storage space is not positioned at the foremost end of the partition of the user space, moving the first storage space to the foremost end of the partition of the user space.

For example, the electronic device may detect whether there is an area with a preset identification in a partition of the user space. If the area with the preset identification exists in the partition of the user space, determining whether the initial position of the area with the preset identification is located at the forefront of the partition of the user space. And if the initial position of the area with the preset identification is not positioned at the foremost end of the partition of the user space, moving the area with the preset identification to the foremost end of the partition of the user space.

With reference to the first aspect, in some embodiments, the storing the location information of the first ROM space and the location information of the first storage space in the location information partition of the electronic device, and merging the first ROM space and the first storage space as the second ROM space of the electronic device may include: acquiring the position information of the first ROM space and the position information of the first storage space from the position information partition; and logically combining the first ROM space and the first storage space by a Device Mapper technology based on the position information of the first ROM space and the position information of the first storage space to obtain the second ROM space.

In other embodiments, merging the first ROM space and the first storage space as the second ROM space of the electronic device may include: and logically combining the first ROM space and the first storage space through other technologies except for a Device Mapper technology to obtain the second ROM space.

In some embodiments, the method further comprises: after the first storage space is moved out of the user space partition, merging the first storage space into a first ROM space by a Device Mapper technology based on the position information of the first storage space and the position information of the first ROM space to form a second ROM space; and writing the position information of the second ROM space into the position information partition, and replacing the position information of the first ROM space.

For example, after the first storage space is moved out of the user space partition, the first storage space may be merged into the System partition by the Device Mapper technique based on the location information of the first storage space and the location information of the first ROM space, forming a new System partition; and then writing the position information of the new System partition into the position information partition, replacing the old position information of the System partition, and taking the new System partition as the System partition when the OTA is updated next time.

In a second aspect, an OTA upgrading apparatus is provided, which includes an obtaining unit, an applying unit, a merging unit, and an upgrading unit. The obtaining unit is used for obtaining a target ROM space required by a new version operating system when detecting that OTA upgrading needs to be carried out on the operating system of the electronic equipment. The application space is used for applying for the first storage space from the user space of the electronic equipment when the target ROM space is larger than the first ROM space of the electronic equipment. The first storage space is an area where user data is not stored in the user space, and the first ROM space is a ROM space used for storing an operating system in an internal storage space of the electronic device before OTA upgrade is performed on the operating system of the electronic device. The merging unit is used for merging the first ROM space and the first storage space as a second ROM space of the electronic device. The upgrading unit is used for performing OTA upgrading on the operating system of the electronic equipment based on the second ROM space.

According to the embodiment of the application, when OTA upgrading needs to be carried out on the operating system of the electronic equipment, the ROM space needed by the new version operating system is determined. And if the ROM space required by the new version of operating system is larger than the first ROM space of the electronic equipment, applying for the first storage space from the user space of the electronic equipment. The first ROM space and the first memory space are then merged as a second ROM space of the electronic device. And when the operation information of the electronic equipment needs to be upgraded by OTA, using the second ROM space to upgrade by OTA.

Therefore, the OT upgrade apparatus can improve the utilization rate of the internal storage space of the electronic device, and can ensure that the user data is not lost, which is equivalent to the first related art and the second related art. In other words, the first storage space is an area of the user space where the user data is not stored, and the whole user space does not need to be adjusted, so that the situation that the user cannot use the electronic device for a long time due to long time required for the adjustment process of the user space does not occur.

The same steps or messages with the same functions in the embodiments of the present application may be referred to with each other between different embodiments.

The service scenario described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not form a limitation on the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of a network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

In the related art one, an OTA upgrading method is provided. In order to ensure that the operating System of the electronic equipment can be still subjected to OTA upgrade after the ROM space required by the operating System of the new version is enlarged relative to the ROM space occupied by the operating System of the old version, a redundant space which cannot be used by a user can be set for a System partition when the System partition of the electronic equipment is set. Since the System partition is provided with the redundant space, in the first related art, OTA upgrade can be performed on the operating System of the electronic device when the ROM space required by the new version of the operating System becomes large.

Illustratively, fig. 1 shows a partition table diagram in the related art. Referring to fig. 1, the partition table of the electronic device may include a plurality of partitions such as an Xloader partition, a System partition, a Vendor partition, and a Data partition. The System partition comprises a System partition redundant space, and a memory space in the System partition except the System partition redundant space is a System actual mirror space. When the ROM space required by the new version of the operating System is enlarged, the electronic equipment can store the new version of the operating System through the System actual mirror image space and the System partition redundant space together, so that OTA upgrading of the operating System of the electronic equipment is realized.

However, since the System partition redundancy space can only be used when the ROM space required by the operating System of a new version becomes large, and the operating System is not always upgraded, the utilization rate of the System partition redundancy space is low. For part of the electronic devices, the System partition redundant space is large, so that the internal storage space of the electronic devices is not fully utilized.

Related art two provides an OTA upgrading method. In this embodiment, a redundant space is not provided in the System partition of the electronic device. When OAT upgrading needs to be carried out on an operating system of the electronic equipment, the ROM space needed by a new version of the operating system is determined. If the ROM space required by the operating system of the new version is larger than the ROM space occupied by the operating system of the old version, the upgrade package can be temporarily stored in the external storage device of the electronic device. And then, modifying the partition table of the electronic equipment, so that the adjusted ROM space can meet the OTA upgrade of the operating system of the new version. And after the partition table of the electronic equipment is modified, storing the upgrade package temporarily stored in the external storage equipment of the electronic equipment into the adjusted ROM space.

According to the OTA upgrading method, the partition table of the electronic equipment is modified, so that the adjusted ROM space can meet OTA upgrading of a new version of operating system. However, when the partition table of the electronic device is modified, a part of the user space is covered, so that a part of the user data is lost.

Related art three provides an OTA upgrading method. In this embodiment, a redundant space is not provided in the System partition of the electronic device. When OAT upgrading needs to be carried out on the operating system of the electronic equipment, the ROM space needed by the operating system of a new version is determined. If the ROM space required by the new version of the operating system is larger than the ROM space occupied by the old version of the operating system, the user space (Data partition in fig. 1) of the electronic device may be first reduced. Correspondingly, the reduced user space is divided into the ROM space, so that the new ROM space is enlarged, and OTA upgrading of a new version of the operating system can be met.

According to the OTA upgrading method, the ROM space is expanded by reducing the whole user space, so that OTA upgrading of a new version of operating system is met. Moreover, the user space is reduced, so that the user data in the user space can be completely stored, and the user data cannot be lost. Wherein the time required for the adjustment process for the entire user space is determined by the condition of the user data in the user space. If the amount of data in the user space is large, the time required for the adjustment process of the user space is long, for example, may reach approximately one hour. And the user cannot use the electronic equipment in the adjustment process of the whole user space. Therefore, in the third related art, although the utilization rate of the internal storage space of the electronic device can be improved and the user data can be ensured not to be lost, the time required by the adjustment process of the user space is long, the efficiency is low, and the user experience can be seriously influenced.

Based on the above problem, an embodiment of the present application provides an OTA upgrading method, which determines a ROM space required by a new version operating system when an operating system of an electronic device needs to be upgraded by an OTA. And if the ROM space required by the new version of operating system is larger than the first ROM space of the electronic equipment, applying for a first storage space from the user space of the electronic equipment, wherein the first storage space does not store user data. The first ROM space is a storage space used for storing the operating system in an internal storage space of the electronic device before OTA upgrade is performed on the operating system. The first ROM space and the first memory space are then merged as a second ROM space for the electronic device. And when the operation information of the electronic equipment needs to be upgraded by OTA, using the second ROM space to upgrade by OTA.

Because the first storage space is still located in the user space, if the user performs factory reset operation on the electronic device, the data in the first storage space is deleted, and a part of data of the operating system is stored in the first storage space. Thus, the first storage space may be moved to the very front of the user space partition. Then, the partition of the first ROM space and the partition of the first memory space are merged into a partition of the second ROM space. Therefore, when the user performs formatting or factory setting restoration operations on the electronic device, the data in the first storage space is not deleted because the first storage space does not belong to the user space.

For example, the electronic device in the embodiment of the present application may be an electronic device such as a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and the specific type of the electronic device is not limited in this embodiment of the present application.

Fig. 2 shows a flowchart of an OTA upgrading method provided in an embodiment of the present application. Referring to fig. 2, the OTA upgrading method includes the following steps:

step 101, obtaining a target ROM space required by a new version of an operating system.

In some embodiments, a user may apply a touch operation in a display interface of an electronic device, and the electronic device determines that OTA upgrade is required to an operating system in response to the touch operation, and obtains a target ROM space required by a new version of the operating system.

For example, after the electronic device obtains the version information of the operating system, the electronic device compares the version information with the current version information of the electronic device to determine whether the operating system needs to be updated through OTA. If the OTA upgrading of the operating system is needed, the electronic equipment can generate an operating system updating control and an operating system non-updating control. The user can apply touch operation to the operating system updating control in the display interface of the electronic device. And the electronic equipment responds to the touch operation and acquires a target ROM space required by a new version of operating system.

For example, the electronic device may determine, according to the obtained version information of the operating system, a target ROM space required by a new version of the operating system. For example, the version information may include the size of the ROM space required by the new version of the operating system.

Step 102, if the target ROM space required by the new version operating system is larger than the first ROM space of the electronic device, applying for a first storage space from the user space of the electronic device, and recording information of the first storage space.

The first ROM space is a storage space used for storing the operating system in an internal storage space of the electronic device before OTA upgrade is performed on the operating system. As shown in fig. 3, the System partition is the first ROM space. Among them, the System partition in fig. 3 has no System partition redundant space compared to the System partition in fig. 1. That is, the System partition in fig. 3 corresponds to the System real mirror space in fig. 1.

After obtaining the target ROM space required by the new version of the operating system, the target ROM space required by the new version of the operating system may be compared to the first ROM space. If the target ROM space required by the new version of the operating system is larger than the first ROM space of the electronic device, the first ROM space cannot store the new version of the operating system. That is, OTA upgrade of the operating system of the electronic device is not possible based on the first ROM space.

At this time, the first storage space may be applied from the user space of the electronic device, and information of the first storage space may be recorded. The first storage space is an area of the user space where user data is not stored (as shown in fig. 4), and the size of the first storage space is determined according to a difference between a target ROM space required by the new version operating system and the first ROM space. For example, if the size of the target ROM space required by the new version of the operating system is a and the size of the first ROM space is b, the first storage space should be greater than or equal to the difference a-b between the target ROM space and the first ROM space.

In some embodiments, the information of the first storage space may include a location and a size of the first storage space. For example, the location and size of the first storage space may be saved into a location information partition, as shown in FIG. 4. In addition, the location information partition may also store therein location information of the first ROM space (i.e., the System partition) and location information of the user space (i.e., the Data partition). In the embodiment of the application, the position of the first storage space is an absolute position of the first storage space in the user space, so that the starting position and the size of the first storage space cannot be found after the file system of the user is damaged.

Step 103, merging the first ROM space and the first storage space as a second ROM space of the electronic device.

In some embodiments, the first ROM space and the first storage space may be logically combined by a Device Mapper technique to obtain a second ROM space of the electronic Device.

For example, as shown in fig. 4, the location information of the first storage space and the location information of the first ROM space may be obtained from the location information partition, and then the System partition and the first storage space are logically merged by the Device Mapper technology based on the location information of the first storage space and the location information of the first ROM space, so as to obtain a new System partition for performing OTA upgrade on the operating System of the electronic Device.

For example, if the first ROM space is b and the first memory space is greater than or equal to a-b, then the resulting second ROM space is greater than or equal to a. Because the ROM space required by the new version of the operating system is a, the second ROM space can meet the requirement of OTA upgrading of the new version of the operating system.

And 104, performing OTA upgrade on the operating system of the electronic equipment by using the second ROM space.

And the new version operating system can be installed in the second ROM space, so that OTA upgrade of the operating system of the electronic equipment is realized. For example, after the operating system upgrade is completed, the electronic device may be rebooted. And after the electronic equipment is restarted, continuing to use the second ROM space to perform OTA upgrade on the operating system of the electronic equipment. For example, after the electronic device is restarted, the first ROM space and the first memory space may be spliced to obtain a second ROM space according to the location and the size of the first memory space, and the second RPM space is used for performing OTA upgrade on an operating system of the electronic device subsequently.

According to the OTA upgrading method, when the OTA upgrading is needed to be carried out on the operating system of the electronic equipment, the ROM space needed by the new version operating system is determined. And if the ROM space required by the new version of operating system is larger than the first ROM space of the electronic equipment, applying for the first storage space from the user space of the electronic equipment. The first ROM space and the first memory space are then merged as a second ROM space for the electronic device. And when the OTA upgrading is needed to be carried out on the operating system of the electronic equipment, the OTA upgrading is carried out by using the second ROM space.

Fig. 5 shows a flowchart of an OTA upgrading method provided in an embodiment of the present application. Referring to fig. 5, based on the OTA upgrading method shown in fig. 3, the OTA upgrading method may further include the following steps:

step 201, detecting whether the first storage space is located at the forefront of the user space partition.

For example, when the preset operation is detected, whether a first storage space exists in the user space partition of the electronic device may be detected, and if the first storage space exists, step 201 may be performed. The preset operation may be an operation of restoring factory settings of the electronic device.

By way of example, the first storage space may be an area having a preset identifier in the user space partition. The electronic device may detect whether the user space partition includes an area with a preset identifier, so as to determine whether the first storage space exists in the user space partition of the electronic device.

It can be understood that, when factory settings are restored to the electronic device, data in the user space partition is deleted. Because the first storage space is still located in the user space, if factory settings are restored to the electronic device at this time, the data in the first storage space is deleted. And the first storage space stores part of data of the new version operating system, so that factory reset cannot be directly executed on the electronic device, and the data in the first storage space needs to be prevented from being deleted. Based on the above, the first storage space can be moved to the forefront of the user space partition, and the initial address of the user space partition is correspondingly modified, so that the new user space partition does not contain the first storage space.

Step 202, the first storage space is moved to the forefront of the user space partition.

In one scenario, after detecting that a touch operation for restoring factory settings is performed on an electronic device, the electronic device detects whether a first storage space is located at the forefront of a user space partition. And if the first storage space is not positioned at the forefront end of the user space partition, moving the first storage space to the forefront end of the user space partition. If the first storage space is located at the forefront of the user space partition, step 203 is executed.

As shown in fig. 4, since the first storage space is not located at the forefront of the Data partition, the electronic device needs to move the first storage space to the forefront of the Data partition, so as to obtain the partition table shown in fig. 6.

In addition, before the first storage space is moved to the foremost end of the user space partition, the data in the first storage space can be backed up, so that the data in the first storage space can be prevented from being lost in the moving process. If the data in the first storage space is lost in the moving process, the backed-up data can be copied to the moved first storage space.

In the process of moving the first storage space, the whole first storage space can be moved to the foremost end of the user space partition at one time according to the starting position and the size of the first storage space.

Step 203, modify the starting position of the user space partition, and move the first storage space out of the user space partition.

The first storage space is moved to the forefront of the Data partition, and then the start address of the Data partition may be modified, and the first storage space is moved out of the Data partition to obtain a new Data partition, as shown in fig. 7. For example, after the first storage space is moved to the forefront of the Data partition, the initial position of the first storage space is x ₁ (as the starting position of the Data partition), and the ending position is x ₂ Then, the first storage space is moved out of the Data subarea to obtain the initial position of a new Data subarea as x ₂ The next position of (a).

After step 203 is executed, the new location information of the user space is written into the location information partition, and the old location information of the user space in the location information partition is replaced.

Since the first storage space is not included in the new Data partition, the Data of the new version of the operating system is not included in the new Data partition. At this time, the factory setting restoration operation is performed on the electronic device, and the data of the new version operating system is not deleted.

For example, after the first storage space is moved out of the user space partition, a new System partition may be formed by adding the first storage space to the System partition through a Device Mapper technique based on the location information of the first storage space and the location information of the first ROM space, as shown in fig. 7. The new System partition in fig. 7 is obtained by merging the System partition and the first memory space in fig. 6, and the new Data partition in fig. 7 is obtained by removing the first memory space from the Data partition in fig. 6. The position information of the new System partition can be written into the position information partition, the old position information of the System partition is replaced, and the new System partition is used as the System partition when the OTA is updated next time.

According to the OTA upgrading method, before factory settings of the electronic equipment are restored, the first storage space is moved to the foremost end of the user space partition, the initial position of the user space partition is modified, and the first storage space and the first ROM space are combined into the second ROM space, so that factory settings of the electronic equipment can be restored, OTA upgrading of an operating system of the electronic equipment cannot be affected, and reliability of OTA upgrading is improved.

The first storage space is an area where user data is not stored in the user space, and the first ROM space is a ROM space used for storing an operating system in an internal storage space of the electronic device before OTA upgrade is performed on the operating system of the electronic device. The merging unit 303 is configured to merge the first ROM space and the first storage space as a second ROM space of the electronic device. The upgrade unit 304 is configured to perform OTA upgrade on the operating system of the electronic device based on the second ROM space.

The OTA upgrading device can improve the utilization rate of the internal storage space of the electronic equipment and can ensure that user data cannot be lost, which is equivalent to the related technology I and the related technology II. Compared with the third related art, the first storage space is an area where user data is not stored in the user space, and the whole user space does not need to be adjusted, so that the situation that the user cannot use the electronic device for a long time due to long time required in the adjustment process of the user space does not occur.
