Referring to fig. 1, fig. 1 is a flowchart illustrating a method for downloading a partition file according to an embodiment of the present application. The method for downloading the partition file may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palmtop computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the partition file downloading method may be as follows:

101. and acquiring a system partition file and at least one specified partition file.

The partition file refers to storing a file in different hard disk partitions (volumes), and the partition file simply refers to storing a file in different partitions of a hard disk or a magnetic disk.

For example, in a Windows operating system (Windows operating system), system files are stored in a system disk (usually a C disk), and other files may be stored in different hard disk partitions according to user requirements; or in the Android system, a plurality of partitions are preset, and the system files are stored in different partitions according to file attributes. Partitioning files is primarily intended to facilitate file management and file protection.

In the embodiment of the present application, the partition file processing method can be applied to an Android system (Android, Android is an operating system of a free and open source code based on a Linux kernel (including no GNU component). The Android system supports dynamic partitioning, which is a user space partitioning system that can create, destroy, or resize partitions via over-the-air (OTA) updates. The user space partitioning system allocates a super partition to the terminal device, and sub-partitions in the super partition can be dynamically resized. The single partition image no longer needs to reserve space for future OTAs, and the remaining available space in the super is available for all dynamic partitions.

The partition map is a map file of a partition file, and the map file is a complete copy file of the information of the optical disc file. Including all information of the optical disc, special virtual optical drive software is needed to load the image file for reading, and the characteristics of reading the optical disc file are completely simulated.

Wherein, the dynamic partition is realized by using a dm-linear device-mapper module in a Linux kernel. The super partition contains metadata that lists the name and block range of each dynamic partition within the super. During the first phase init execution, the system will parse and validate these metadata and create a virtual block device to represent each dynamic partition. Specifically, when the OTA is applied, the partition system may automatically create/delete the dynamic partition or adjust the size of the dynamic partition as needed.

In the embodiment of the application, the Android system includes a plurality of partitions, for example, a boot partition, a system partition, a recovery partition, a cache partition, a userdata partition, a vendor partition, an odm partition, and the like. Different partitions may be used to store different files.

Specifically, the boot partition comprises a kernel image and a ramdisk which are combined together through mkboot, and after system-as-root is enabled, the boot partition supports storing the kernel image; the system partition mainly comprises an Android framework. After system-as-root is enabled, the system partition will contain the merged contents of the original system.img and ramdisk.img; the recovery partition is used for storing a recovery system used in OTA upgrading; the cache partition is used for storing temporary data, and the OTA upgrade package can be downloaded to the cache partition; the userdata partition can store applications and data installed by a user; the vendor partition comprises all binary files which cannot be distributed to the Android open source project; the ODM partition is used for ODM (original design manufacturer) to customize its own board level support package.

In this embodiment of the present application, the partition table is used to store the image file and partition information corresponding to the image file, and the partition information may include: partition name, partition size, partition offset address, etc.

The offset address is an offset of an address in a segment with respect to a segment first address (segment address) after a memory in the computer is segmented. For example, an 8086 memory system has a 20-bit physical address (i.e., the actual address of the data store) that is 16-bit offset from a 16-bit segment base address. For example, the offset address may be 0060H.

The audio circuit 606 may transmit the electrical signal converted from the received audio data to a speaker, and convert the electrical signal into a sound signal for output; on the other hand, the microphone converts the collected sound signal into an electrical signal, which is received by the audio circuit 606 and converted into audio data, which is then processed by the audio data output processor 608, and then passed through the RF circuit 601 to be sent to, for example, a terminal, or the audio data is output to the memory 602 for further processing. The audio circuitry 606 may also include an ear-bud jack to provide communication of peripheral headphones with the server.

WiFi belongs to short-distance wireless transmission technology, and the terminal can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 607, and provides wireless broadband internet access for the user. Although fig. 4 shows the WiFi module 607, it is understood that it does not belong to the essential constitution of the terminal, and may be omitted entirely as needed within the scope of not changing the essence of the application.

The processor 608 is a control center of the terminal, connects various parts of the entire handset using various interfaces and lines, and performs various functions of the server and processes data by operating or executing software programs and modules stored in the memory 602 and calling data stored in the memory 602, thereby performing overall monitoring of the handset. Optionally, processor 608 may include one or more processing cores; preferably, the processor 608 may integrate an application processor, which primarily handles operating systems, user interfaces, applications, etc., and a modem processor, which primarily handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 608.

The terminal also includes a power supply 609 (e.g., a battery) for powering the various components, which may preferably be logically connected to the processor 608 via a power management system that may be used to manage charging, discharging, and power consumption. The power supply 609 may also include any component of one or more dc or ac power sources, recharging systems, power failure detection circuitry, power converters or inverters, power status indicators, and the like.
