The following are detailed below. It should be noted that the description sequence of the following embodiments is not intended to limit the priority sequence of the embodiments.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a system software generating method according to an embodiment of the present application. The specific flow of the system software generation method can be as follows:

101. and acquiring a forced upgrade package of the system software of the first terminal device after the test is finished.

In the embodiment of the present application, a forced upgrade package corresponding to the system software on the first terminal device after the test is completed is obtained.

In the embodiment of the application, the tested system Software is system Software meeting an SQA (Software Quality Assurance) standard, wherein the Software Quality Assurance is a set of planned and systematic methods for ensuring that proposed standards, steps, practices and methods can be correctly adopted by all projects to a management layer, and Software products and activities are reviewed and audited to verify that the Software is in accordance with the standards.

After the system software of the terminal device is compiled, a User Interface (UI) file and a code are compiled, and then a script (such as a batch file code-img.bat) can be executed to generate a forced upgrade package, wherein in the conventional case, the forced upgrade package is copied to a memory of a driver chip (EMMC) of the second terminal device, and the terminal device can be restarted to see an upgrade prompt and select an upgrade.

102. And analyzing the forced upgrade package to obtain at least one module image file.

In the embodiment of the present application, parsing the forced upgrade package, that is, unpacking the forced upgrade package, obtains a plurality of module image files by unpacking, where the unpacking may be performed according to a compiling and packing rule, in the embodiment of the present application, the module image files include files with a file format of image (image), and in the embodiment of the present application, the module image files are binary data files corresponding to each module of the system software.

In this embodiment of the present application, the mandatory upgrade package may be encrypted when being packaged to prevent leakage of data in the mandatory upgrade package, and therefore, before unpacking the mandatory upgrade package, the mandatory upgrade package needs to be decrypted first, that is, optionally, in some embodiments, the step "parsing the mandatory upgrade package to obtain at least one module image file" may specifically include:

unpacking the forced upgrade package according to the software compiling and packaging rule;

when the software compiling and packaging rule is encrypted, the software compiling and packaging rule is decrypted based on the encrypted rule so as to restore and obtain a forced upgrading package of the original version;

and unpacking the forced upgrade package of the native version to obtain at least one module image file.

The encryption of the forced upgrade package can effectively prevent the leakage of data in the forced upgrade package, and meanwhile, the malicious entry of problem data is also effectively prevented, and the accuracy of system software generation is improved.

And determining a decryption rule according to the encryption rule of the forced upgrade package, decrypting according to the decryption rule to obtain the forced upgrade package of the original version, and unpacking the forced upgrade package of the original version to obtain the real module image file.

The method comprises the steps of generating a pre-copying file automatically, generating system software automatically, and completing relevant operations automatically by a script in the whole operation process. Wherein the encryption rules may be obtained from the developer.

Because the data size of part of the module image files is large, it is necessary to split the large module image file in advance in the transmission process of the forced upgrade package, that is, split the module image file (module image parent file) into a plurality of child files for transmission, and therefore, a plurality of image files obtained after splitting the forced upgrade package also need to be synthesized according to the parent file to which the image files belong, and synthesized into a module image parent file, that is, optionally, in some embodiments, the step "parsing the forced upgrade package to obtain at least one module image file" may specifically include:

splitting the forced upgrade package to obtain at least one module mirror image subfile;

determining a module image parent file corresponding to each module image child file;

and automatically synthesizing at least one module mirror image child file corresponding to each module mirror image parent file according to the file format of the module mirror image parent file to obtain at least one module mirror image parent file.

According to the requirement of a simple File Transfer Protocol (Tftp), the size of a transmitted File cannot be too large, so that a large File needs to be split into smaller files which can be transmitted in advance, and in order to ensure the accuracy of data, small files need to be synthesized into an original large File after transmission;

the forced upgrade package is divided to obtain a plurality of module image sub-files, and the module image sub-files can be re-synthesized into a parent file according to the parent file to which the module image sub-files belong, so that the parent file with larger data can be restored, wherein the accuracy of generating the subsequent pre-copy file can be improved after the parent file is restored.

In the process of synthesis, sequential synthesis can be performed according to the splitting sequence of the module mirror image subfiles, for example, in the splitting process, the child files are sequentially split according to the sequence of the content of the parent file, then when the child files synthesize the parent file, the child files can be synthesized into the original parent file according to the splitting sequence of the child files, and the file content is ensured not to be disordered after splitting and synthesis, or in the splitting process, the content of the parent file is transmitted in segments, each segment generates one child file, then, according to the sequence of the segments in the parent file, sequential synthesis of each child file is performed, and the consistency of data before and after transmission can be realized.

In the synthesizing process, the restoration is further performed according to the format of the parent file, for example, in the embodiment of the present application, the sparse matrix file (sparse) of Android (Android) in the format of the parent file may be restored according to the format of the sparse matrix file when restoring.

For the data before and after transmission, the consistency of the data can be checked according to an information summarization Algorithm (MD5, Message-Digest Algorithm), so as to ensure the consistency of the data before and after transmission and improve the accuracy of generating the pre-transcription file.

103. And modifying the target module image file selected from the at least one module image file according to the startup default configuration data to obtain the modified module image file.

According to the requirement of a factory for initializing the terminal equipment, the terminal equipment needs to have default configuration after being started, namely, the whole terminal equipment is in a power-on state, for example, for a television, the first start must be as follows: the method comprises the steps that a TV information source directly enters a factory debugging mode, a default channel is a factory internal production line frequency point, a serial port is opened, automatic volume is closed, starting time is within 30 seconds, no user data exists and the like, so that when a pre-copy file is generated, corresponding parameters in an image file can be modified, and when terminal equipment generates system software according to the pre-copy file, starting default configuration data can be directly generated.

The target module image file to be modified is determined through the startup default configuration data, so that the accuracy of obtaining the target module image file can be improved, for example, the target module image file to be modified can be determined according to the data type of the startup default configuration data.

In some embodiments, the step "modifying the target module image file selected from the at least one module image file according to the startup default configuration data to obtain the modified module image file" may specifically include:

carrying out mirror image format conversion on the module mirror image file to obtain at least one mirror image format conversion file;

determining a mirror image file directory hierarchy of a mirror image format conversion file;

determining at least one mirror image format conversion file to be modified according to the startup default configuration data and the mirror image file directory hierarchy;

modifying the mirror image format conversion file according to the startup default configuration data to obtain a modified mirror image format conversion file;

and recovering the format of the modified mirror image format conversion file to obtain at least one modified module mirror image file.

In the embodiment of the application, the image format of the module image file includes a Sparse matrix file (Sparse) of Android (Android), so that the format of the module image file can be converted into an extended file (ext) of linnax (linux), then, each extended file is mounted to obtain a directory hierarchy of each extended file, then, according to default configuration data of the boot, the extended file to be modified is selected from the directory hierarchy, and according to the selected extended file to be modified, the module image file to be modified can be determined.

The converted image file in the file format can be directly modified according to the startup default configuration data, and the parameter value to be modified can be determined through the startup default configuration data, wherein after the parameter modification is performed on the converted file, the format of the file can be restored to a system file (for example, a file in an android system format) required by the second terminal device, so that the determination and modification of the image file of the module to be modified are realized.

When the mirror format file is modified according to the startup default configuration data, a corresponding manner may be selected to modify the mirror format conversion file according to the type of the mirror format conversion file to be modified, that is, optionally, in some embodiments, the step "modifying the mirror format conversion file according to the startup default configuration data" may specifically include:

when the mirror image format conversion file comprises a database file, directly modifying a field variable value corresponding to the startup default configuration data in the database file according to the database operation command;

and when the mirror image format conversion file comprises an environment variable configuration file, directly opening the environment variable configuration file, and modifying corresponding parameters in the environment variable configuration file according to the startup default configuration data.

The method includes the steps of directly logging in a corresponding database aiming at a database file, calling a database operation command, modifying field variable values in the database, saving and quitting to regenerate the database file after modification, and replacing an original database file, or directly modifying the corresponding field variable values in the database file.

For example, the partition environment variables are modified, such as a factory mode is opened, a serial port is opened, and partition header files (such as gpt.

In some embodiments, the step "modifying the target module image file selected from the at least one module image file according to the default configuration data for startup to obtain a modified module image file" may specifically include:

directly and independently modifying the module codes or data of the mirror image file of the target module;

and compiling the modified target module image file to obtain the modified module image file.

The target module image file is modified independently, so that the efficiency of modifying the module image file can be improved, and the whole generation efficiency of the pre-copy file is improved.

After the target module image file is modified, the modified module image file can directly replace the unpacked module image file with the same name.

When modifying the target module image file, it is necessary to determine whether the target module image file is a compressed file, and when the target module image file is a compressed file, it is also necessary to decompress the target module image file first, and modify corresponding file parameters after decompression, that is, optionally, in some embodiments, when the module image file includes a compressed module compressed image file, the method further includes:

decompressing the module compressed image file to obtain at least one original format image file;

the step of "modifying the target module image file selected from the at least one module image file according to the startup default configuration data" may specifically include:

and modifying the target module image file selected from the at least one original format image file according to the startup default configuration data to obtain a modified module image file.

The generation of the pre-copy file is an automatic process, so that the file after the forced upgrade package is unpacked needs to be detected to detect whether the file is a compressed file, wherein the compressed file needs to be decompressed, and the content of the file can be modified only after the file is decompressed.

The method comprises the steps of compressing the mirror image file, so that the efficiency of file data transmission can be improved, but when the mirror image file needs to be modified, the compressed file needs to be converted into a non-compressed file, and when the binary file is written into a partition, the decompressed mirror image file also needs to be decompressed, so that the mirror image file can be automatically decompressed in the automatic generation process of the pre-copy file, wherein when the compressed mirror image file is decompressed, corresponding decompression software can be called to decompress according to the type of the compressed file.

After the original format image file is modified, the format of the modified image file is restored, and the modified module image file can be obtained.

104. And respectively writing the residual module image file and the modified module image file into a preset empty binary file according to a preset file partition rule of a memory in the second terminal equipment to obtain a pre-copy file.

And the residual module image file is at least one module image file except the target module image file in at least one module image file.

The memory of the second terminal device comprises a driver chip mounted on the terminal device circuit board, wherein a preset file partition rule in the memory of the second terminal device is a partition configuration definition table which is predefined in a memory of the driver chip according to a software project compiling rule, wherein all image files are traversed according to the partition configuration definition table and then sequentially written into a binary file to obtain a pre-copy file, and the driver chip comprises an embedded memory (EMMC, Embedded multimedia Card). The pre-copy file is burned into the drive chip, so that the efficiency of generating the system software can be improved.

105. And sending the pre-copy file to the second terminal equipment so that the second terminal equipment generates system software according to the pre-copy file.

After receiving the pre-copy file in the memory (driver chip) of the second terminal device, the second terminal device has system software. Specifically, the second terminal device may burn the pre-copy file into the driver chip, then attach the driver chip to the circuit board of the target terminal system, and burn the pre-copy file into the driver chip, so that the efficiency of generating the system software in the second terminal device may be improved.

In summary, referring to fig. 3, fig. 3 is a schematic flow chart of a method for generating a pre-transcription file according to an embodiment of the present application, which specifically includes:

111. acquiring a system software forced upgrade package (update. img) of a release version after testing;

112. analyzing or unpacking the forced upgrade package to obtain a module mirror image compression sub-file of each module;

113. decompressing each module image compression sub-file to obtain a module image sub-file (the decompression tool uses Iz4_ compress _ tool);
