Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computers, and in particular to a dynamic partition burning method and device, a chip, a chip module, and a storage medium. BACKGROUND

[0002] Dynamic partitioning refers to dividing a physical partition into multiple logical partitions, and the physical partition also contains a certain reserved space. The reserved space is filled with 0-byte data. Burning a dynamic partition refers to burning a system image file of the dynamic partition to each logical partition and the reserved space. The system image file of the dynamic partition is compiled into a sparse matrix storage format by default, that is, a compressed format. When burning, the system image file in the sparse format needs to be converted into a non-compressed format for burning, or the system image file in the compressed format is burned and converted during burning. Regardless of which method is used, the system image file burned onto the physical device is always in the non-compressed format.

[0003] When the system image file of the dynamic partition is converted into the non-compressed format, the prior art converts according to the partition size configured by the system. Assuming that the dynamic partition includes the following logical partitions: system, system extension, product, and vendor, the actual size of the dynamic partition is the total size of system, system extension, product, vendor, and the reserved space. For example, the size of the dynamic partition configured by the current system is 6G, the actual size of system, system extension, product, and vendor is 4G, and the reserved space is 2G. The actual size of the dynamic partition converted into the non-compressed format is 6G. When burning, the system image file is downloaded according to the actual size of the dynamic partition, which is relatively low in download and burn efficiency and time-consuming. SUMMARY

[0077] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below with reference to the drawings.

[0078] It should be clear that the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0079] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0080] It should be understood that the term "and / or" used herein is only to describe the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in this paper generally represents that the front and rear associated objects are a "or" relationship.

[0081] Terminals, such as mobile phones, computers, tablets, wearable devices, etc., need to install an operating system before they can be used by users. For example, a mobile phone needs to install a mobile phone operating system (such as an Android system) before it can be used by a user. Since the installation process of the operating system is relatively cumbersome, and the operating system of some terminals needs special equipment to install, in order to facilitate the user to use the terminal, the terminal usually has a basic operating system installed before the terminal is sold. In this way, the user does not need to perform complex operating system installation operations after purchasing the terminal, and can use the terminal. For example, before the mobile phone is sold to the user, the mobile phone has installed a basic mobile phone operating system. The user can directly use the basic functions of the mobile phone (such as connecting to a mobile network, making a call) after purchasing the mobile phone.

[0082] In actual application scenarios, a common pre-delivery basic operating system installation method is to directly burn a basic operating system (such as a basic Android system provided by Google) to the device by a burning device. Figure 1 The burning system framework structure diagram of the system burning of the device before delivery in an application scenario is shown, as shown in Figure 1As shown, after the terminal 100 completes hardware assembly, it is connected to the burning device 110, and the memory 120 is connected to the burning device 110. The memory 120 stores the basic system installation package of the basic operating system, which contains the image file of the basic operating system. The burning device 110 reads the basic system installation package from the memory 120, parses the package to obtain the image file of the basic operating system, and performs data burning based on the image file of the basic operating system. The operating system data corresponding to the image file of the basic operating system is burned onto the memory of the terminal 100, thereby realizing the installation of the basic operating system on the terminal 100.

[0083] The terminal 100 in this application embodiment includes, but is not limited to, smartphones, smart headphones, tablets, smart refrigerators, smart speakers, etc., that can install an operating system. The terminal 100 can also be a control board internally installed with an operating system. Exemplary embodiments of the operating system include, but are not limited to, Android or other operating systems.

[0084] Taking Android systems that use the virtual A / B upgrade method as an example, Figure 2 The diagram shows the data storage structure of the Android system on a terminal. Figure 2 As shown, the Android system data storage area includes a basic partition (common), a static partition (A), a static partition (B), a dynamic partition (super), and a user data partition (userdata). Userdata stores user personal data, such as apps installed by the user, saved pictures, documents, and videos. The basic partition stores system data that does not participate in operating system upgrades. The structures of static partitions (A) and (B) correspond to each other, and sub-partitions are distinguished by the suffixes _a and _b. Static partition (A) includes bootloader_a, boot_a, vendor_boot_a, dtbo_a, and vbmmeta_a; static partition (B) includes bootloader_b, boot_b, vendor_boot_b, dtbo_b, and vbmmeta_b. The dynamic partition contains multiple sub-logical partitions (system, system_ext, product, vendor, cust, odm). For software upgrade needs, the dynamic partition may also include reserved space.

[0085] The dynamic partition means that the content of the whole partition dynamically changes, and is widely applied in the Android platform at present. The dynamic partition is essentially composed of sub-logical partition images, and exists to improve the utilization of space. If each sub-logical partition is an actual physical partition, each partition needs to reserve space required for upgrading, and the reserved space cannot be shared between the physical partitions. The dynamic partition is a mechanism introduced to solve this problem.

[0086] At the device startup, a static partition is started. For example, the device is started from the static partition (A): the base partition, the static partition (A) and the dynamic partition are loaded in sequence; the device is started from the static partition (B): the base partition, the static partition (B) and the dynamic partition are loaded in sequence.

[0087] In view of the low download and burning efficiency in the background art, the application provides a burning scheme of a dynamic partition. The total size of at least one system image data in a first system image file to be burned to the dynamic partition is acquired. The format of the first system image file is a non-sparse matrix format, and the dynamic partition includes at least one sub-logical partition. The information of the total size is written into the header information of a second system image file. The second system image file is a sparse matrix format file of the first system image file. According to the header information, the at least one system image data in the first system image file is burned to the at least one sub-logical partition respectively. Thus, only the system image data of each sub-logical partition needs to be downloaded and burned, and the reserved space does not need to be burned, thereby improving the download and burning efficiency.

[0088] As shown in FIG. 1, a flowchart of a burning method of a dynamic partition provided by an embodiment of the application is shown. The method can include the following steps: Figure 3

[0089] S301. The total size of at least one system image data in a first system image file to be burned to the dynamic partition is acquired. The format of the first system image file is a non-sparse matrix format, and the dynamic partition includes at least one sub-logical partition.

[0090] As shown in FIG. 1, a flowchart of a burning method of a dynamic partition provided by an embodiment of the application is shown. The method can include the following steps: Figure 4 ​The diagram shows the structure of a dynamic partition in a current actual flashing process. For example, the system creates a dynamic partition, which includes sub-logical partitions such as system, system_ext, product, and vendor, and may also include reserved space. The size of the dynamic partition configured by the system is the size of the aforementioned sub-logical partitions and the reserved space. If the reserved space is too large, it will affect the flashing efficiency. For example, in common mobile Android devices, flashing the dynamic partition accounts for 90% of the entire flashing time. Optimizing the download efficiency of the dynamic partition can greatly improve the overall software download and flashing efficiency of the flashing device.

[0091] Store to Figure 1 The system image files of the dynamically partitioned memory 120 shown are all compiled into a sparse matrix format by default, which is a compressed format. During programming, the sparse matrix format needs to be converted to a non-sparse matrix format. Currently, common programming methods include converting a second system image file downloaded from memory 120 in sparse matrix format into a first system image file in non-sparse matrix format for programming, or programming the second system image file and converting it during the programming process. Regardless of the programming method, the final file programmed to the terminal will always be the first system image file in non-sparse matrix format.

[0092] In this embodiment, to improve the software download and burning efficiency of the burning device 110, a second system image file is downloaded from the memory 120. This second system image file is in sparse matrix format as the first system image file. The total size of at least one system image data in the first system image file to be burned to the dynamic partition is obtained. This first system image file is in non-sparse matrix format.

[0093] like Figure 5 The diagram shown illustrates the structure of the dynamic partition actually burned in this application example. The actual dynamic partition includes the following sub-logical partitions: system, system_ext, product, and vendor, excluding reserved space. The total size of at least one system image data in the first system image file to be burned into the dynamic partition is obtained.

[0094] S302. Write the total size information into the header information of the second system image file.

[0095] The programming device 110 downloads a second system image file from the memory 120 and performs programming based on the second system image file. After obtaining the total size information of at least one system image data in the first system image file to be programmed into the dynamic partition, the programming device 110 can write the total size information into the header information of the second system image file.

[0096] S303. According to the header information, at least one system image data in the first system image file is respectively burned into at least one sub-logical partition.

[0097] The whole dynamic partition image is composed of sub-logical partition images, and when burned, a fixed-size block is read from the large dynamic partition and written one by one for downloading, and after obtaining the information of the total size of at least one system image data in the first system image file to be burned into the dynamic partition, because the content in the reserved space is all 0-byte data filled, which has no actual meaning, therefore, the block in the dynamic partition reserved space does not need to be burned, so as to improve the downloading and burning efficiency.

[0098] In a specific implementation, when burned, the burning device 110 converts the second system image file into the first system image file in the non-sparse matrix format, and according to the information of the total size of at least one system image data in the first system image file to be burned into the dynamic partition, at least one system image data in the first system image file is respectively burned into at least one sub-logical partition. That is, the actual size of the sub-logical partition is taken as the end address, and after burning each sub-logical partition, the burning and writing are completed. Wherein, the first system image file includes at least one system image data.

[0099] According to the dynamic partition burning method provided by the embodiment of the application, when burned, according to the total size of at least one system image data in the first system image file, only at least one system image data needs to be downloaded and burned, and the reserved space does not need to be burned, so as to improve the downloading and burning efficiency.

[0100] As shown in FIG. 6, the method provided by the embodiment of the application can include the following steps: Figure 6

[0101] S601. Obtain configuration information.

[0102] Obtain the configuration information of the system. The configuration information includes the size of the dynamic partition. For example, the system creates a dynamic partition, which includes each sub-logical partition of system, system_ext, product, vendor and the reserved space. The size of the dynamic partition configured by the system is the size of each sub-logical partition and the reserved space.

[0103] S602. According to the configuration information, create a physical partition of the dynamic partition.

[0104] ​Before burning the dynamic partition, the physical partition of the dynamic partition is created according to the configuration information. As described above, the total reserved space for upgrading each sub-logical partition is a total reserved space. Each sub-logical partition, the reserved space and the physical partition of the dynamic partition have a certain correspondence in address. When burning, the first system image file in the non-sparse matrix format needs to be burned into the physical partition of the dynamic partition. Specifically, at least one system image data in the first system image file needs to be burned into the physical partition corresponding to at least one sub-logical partition.

[0105] S603. Obtain a second system image file.

[0106] The burning device 110 downloads the second system image file from the storage 120, and the burning will be performed according to the second system image file. The second system image file is a sparse matrix format file of the first system image file.

[0107] S604. Obtain the first system image file according to the second system image file.

[0108] After the burning device 110 obtains the second system image file, the first system image file can be obtained according to the second system image file. The first system image file is in a non-sparse matrix format. That is, the second system image file is converted into the first system image file.

[0109] S605. Obtain the size of at least one system image data in the first system image file.

[0110] After the burning device 110 obtains the first system image file, the first system image file includes at least one system image data, and therefore, the size of at least one system image data in the first system image file can be obtained according to the first system image file.

[0111] S606. Obtain the total size of at least one system image data in the first system image file according to the size of at least one system image data in the first system image file.

[0112] The total size of at least one system image data in the first system image file can be the sum of the sizes of each system image data in the first system image file.

[0113] S607. Write the information of the total size into the header information of the second system image file. The second system image file is a sparse matrix format file of the first system image file.

[0114] After the burning device 110 obtains the information of the total size of at least one system image data in the first system image file to be burned into the dynamic partition, the information of the total size can be written into the header information of the second system image file.

[0115] S608. According to the header information, the at least one system image data in the first system image file is respectively burned into the at least one sub-logical partition.

[0116] The burning device 110 converts the second system image file into the first system image file in the non-sparse matrix format during the burning, and according to the information of the total size of the at least one system image data in the first system image file to be burned into the dynamic partition, the at least one system image data in the first system image file is respectively burned into the at least one sub-logical partition. That is, the burning is completed after the sub-logical partition is burned to the actual size of the sub-logical partition as the end address. The first system image file includes at least one system image data.

[0117] S609. Stop transmitting and filling the all-0 data into the reserved space.

[0118] After the burning of each sub-logical partition is completed, the burning device 110 stops transmitting and filling the all-0 data into the reserved space. Thus, the burning of the dynamic partition is completed.

[0119] As described above, the burning of the dynamic partition occupies ninety percent of the time of the entire mobile Android device burning. Since the burning of the reserved space is saved, the burning time of the dynamic partition is saved, and thus the time of the entire terminal burning is saved.

[0120] S610. The all-0 data is filled into the reserved space by the start-up boot program.

[0121] Further, after the burning of the terminal is completed, the all-0 data can be filled into the reserved space by the start-up boot program when the terminal is started.

[0122] According to the burning method of the dynamic partition provided in the embodiment of the present application, during the burning, according to the total size of the at least one system image data in the first system image file, only the at least one system image data needs to be downloaded and burned, and the reserved space does not need to be burned, thereby improving the downloading and burning efficiency.

[0123] In view of the low downloading and burning efficiency in the background art, the present application provides another burning scheme of the dynamic partition. By obtaining the at least one system image data in the second system image file in the non-sparse matrix format, the at least one system image data is respectively burned into the at least one sub-logical partition of the dynamic partition, so that during the burning, only the at least one system image data needs to be downloaded and burned, and the reserved space does not need to be burned, thereby improving the downloading and burning efficiency.

[0124] As Figure 7As shown, a flowchart of another dynamic partitioning burning method provided by the embodiments of the present application is shown, which can include the following steps:

[0125] S701. Obtain a first system image file.

[0126] The burning device 110 downloads the first system image file of the dynamic partitioning from the storage 120. The first system image file is a sparse matrix format file. Exemplarily, the dynamic partitioning includes each sub-logical partition of system, system_ext, product, vendor, and can also include a reserved space.

[0127] S702. Obtain a second system image file according to the first system image file.

[0128] The burning device 110 converts the first system image file into the second system image file. The second system image file is in a non-sparse matrix format, and the first system image file is a sparse matrix format file of the second system image file. The second system image file includes system image data of each sub-logical partition.

[0129] S703. Obtain at least one system image data in the second system image file.

[0130] After the burning device 110 obtains the second system image file, at least one system image data in the second system image file can be obtained.

[0131] Specifically, first, a sub-logical partition information table is obtained, which includes address ranges of at least one sub-logical partition. Then, according to the sub-logical partition information table, at least one system image data corresponding to the address range of at least one sub-logical partition in the second system image file is obtained.

[0132] S704. Burn at least one system image data to at least one sub-logical partition of the dynamic partitioning, respectively.

[0133] After the burning device 110 obtains at least one system image data, at least one system image data is burned to the corresponding sub-logical partition, respectively. After burning each sub-logical partition, the burning is completed.

[0134] Further, the method can also include the following steps (shown by dashed lines in the figure):

[0135] S705. Stop transmitting and filling all 0 data to the reserved space.

[0136] After completing the burning of each sub-logical partition, the burning device 110 stops transmitting and filling all 0 data to the reserved space. Thus, the burning of the dynamic partitioning is completed.

[0137] As described above, the dynamic partition burning occupies 90% of the time of the entire mobile Android device burning. The reserved space burning is saved, and the dynamic partition burning time is saved, and the entire terminal burning time is saved.
