[0033] It should be understood that Figure 1 The number of operating system transplantation platforms 101, networks 102, IDE platforms 103 and terminal devices 104 is only illustrative. According to implementation requirements, there can be any number of operating system transplantation platforms 101, networks 102, IDE platforms 103 and terminal devices 104, which are not limited here.

[0037] It should be noted that the data processing method provided in the embodiment of the present application is generally executed by the operating system transplantation platform 101 , and accordingly, the data processing device is generally arranged in the operating system transplantation platform 101 .

[0038] The implementation details of the technical solution of the embodiment of the present application are elaborated in detail below.

[0039] Figure 2A flowchart of a data processing method according to an embodiment of the present application is shown. The data processing method can be executed by an operating system transplantation platform. The operating system transplantation platform can be Figure 1 The operating system transplantation platform 101 shown in FIG. Figure 2 As shown, the data processing method at least includes steps S210 to S250, which are described in detail as follows:

[0040] In step S210, a hardware configuration file generated for hardware configuration of the microcontroller unit is obtained, and an operating system transplantation file corresponding to the operating system to be transplanted is obtained. The hardware configuration file includes a hardware configuration source file and a hardware engineering file corresponding to the hardware configuration source file. The operating system transplantation file includes an operating system source file and an operating system engineering file corresponding to the operating system source file.

[0041] In one embodiment, the hardware configuration file refers to a file generated by performing hardware configuration on a microcontroller unit in a terminal device, and the operating system transplantation file includes a hardware configuration source file and a hardware engineering file corresponding to the hardware configuration source file.

[0042] The hardware configuration source file refers to a source file containing the source code of the logic layer of the microcontroller unit in implementing the relevant hardware functions, specifically, including the source file of the source code for implementing the hardware initialization function and the source file of the source code for implementing the interrupt function. It can be understood that the hardware configuration source file can also include a user configuration file that records the hardware configuration information in the microcontroller unit, such as the internal clock frequency of the microcontroller unit, ROM size, ROM offset address, RAM memory size and RAM offset address and other hardware configuration information.

[0043] The hardware engineering file is an engineering file that instructs how to compile the hardware configuration source file. Based on the hardware engineering file, the source code in the hardware engineering file can be compiled to generate a binary file for program burning.

[0044] In one embodiment, the hardware configuration file may be specifically generated by a developer using a hardware configuration tool provided by a microcontroller unit manufacturer to perform hardware configuration according to the microcontroller unit to which the operating system is to be transplanted as required.

[0045] In one embodiment, the operating system transplantation file refers to a file information containing all logic layer source codes and related engineering files corresponding to the operating system. The operating system transplantation file includes the operating system source file and the operating system engineering file corresponding to the operating system source file.

[0046] The operating system source file is a source file containing all logic layer source codes corresponding to the operating system, and specifically, may include a source file of source code for implementing an interrupt function and a source file of source code for implementing an operating system initialization function.

[0047] The operating system project file is a project file that instructs how to compile the operating system source file. Based on the operating system project file, the source code in the operating system source file can be compiled to generate a binary file for program burning.

[0048] refer to Figure 3 , Figure 3 A specific flow chart of step S210 of the data processing method according to an embodiment of the present application is shown. Step S210 may specifically include steps S310 to S320, which are described in detail as follows.

[0049] In step S310, a first type of source file and a first type of project file are obtained, and the first type of source file and the first type of project file are copied to a predetermined first directory.

[0050] In step S320, the second type of source files and the second type of project files are obtained, and the second type of source files, the second type of project files, the hardware configuration source files and the hardware project files are copied to a predetermined second directory, where the first directory and the second directory are different directories under the operating system transplantation directory.

[0051] In one embodiment, the operating system source file may be a source file that is pre-compiled and stored in the operating system transplantation platform. The operating system source file includes a first type of source file and a second type of source file. The first type of source file refers to a source file containing a logic layer source code that does not perform a modification process in the operating system source file, and the second type of source file refers to a source file containing a logic layer source code that performs a modification process in the operating system source file. The operating system engineering file includes a first type of engineering file corresponding to the first type of source file and a second type of engineering file corresponding to the second type of source file. The first type of engineering file is an engineering file that indicates how to compile the first type of source file, and the second type of engineering file is an engineering file that indicates how to compile the second type of source file.

[0052] In one embodiment, in order to facilitate system transplantation, a first directory and a second directory may be created in advance, and the first type of source files and the first type of engineering files may be copied to the first directory, and the second type of source files, the second type of engineering files, the hardware configuration source files and the hardware engineering files may be copied to the second directory. By placing the logic layer source code for executing the modification process and the logic layer source code for not executing the modification process into different source files, and placing the second type of source files containing the logic layer source code for executing the modification process into the same directory as the hardware configuration source files and the hardware engineering files, it is beneficial to improve the efficiency of modifying the logic layer source code in the hardware configuration source file based on the logic layer source code in the operating system source file.

[0053] In one embodiment, due to differences in chip architecture, manufacturer, model, etc. of the microcontroller units on the terminal devices, when the operating system is ported to the microcontroller unit, the logic layer source code in the operating system needs to be modified.

[0054] In order to improve the efficiency of system transplantation, corresponding source files can be developed according to the differences in system transplantation for different models of microcontrollers, that is, corresponding second source files and second-type engineering files can be developed for different models of microcontrollers, and the developed second source files and second-type engineering files can be stored in the file library.

[0055] Specifically, when generating a file library containing second source files and second-category engineering files, the model information of the microcontroller unit can be used as index information, and it can be associated with the corresponding second source files and second-category engineering files, thereby facilitating the acquisition of second-category source files and second-category engineering files that have a corresponding relationship with the model information based on the model information of the microcontroller unit.

[0056] In step S220, the logic layer source code in the hardware configuration source file is modified based on the logic layer source code in the operating system source file to generate a modified source file.

[0057] In one embodiment, since the hardware configuration source file only includes the source code file for realizing the hardware initialization function, the terminal device can only realize the hardware initialization function. After the operating system is transplanted to the microprocessor unit of the terminal device, the terminal device needs to realize both the hardware initialization function and the operating system initialization function in the initialization logic, so it is necessary to modify the logic layer source code in the hardware configuration source file based on the logic layer source code in the operating system source file.

[0058] In addition, since the source code for implementing the interrupt function contained in the hardware configuration source file is only applicable to the case where there is no operating system, when the microprocessor unit supports the operating system, the logic layer source code in the hardware configuration source file needs to be modified based on the logic layer source code in the operating system source file.

[0059] In one embodiment, step S220 of modifying the logic layer source code in the hardware configuration source file based on the logic layer source code in the operating system source file includes: modifying the source code that implements the interrupt function in the hardware configuration source file based on the source code that implements the interrupt function in the operating system source file, and modifying the source code that implements the hardware initialization function in the hardware configuration source file based on the source code that implements the operating system initialization function in the operating system source file.

[0060] In this embodiment, when the logic layer source code in the hardware configuration source file is modified based on the logic layer source code in the operating system source file, the source code for implementing the interrupt function in the hardware configuration source file can be modified by the source code for implementing the interrupt function in the operating system source file, thereby enabling the terminal device to adapt to the situation of having an operating system.

[0061] The source code implementing the operating system initialization function in the operating system source file is modified and processed to implement the source code implementing the hardware initialization function in the hardware configuration source file, so that the terminal device can implement the hardware initialization function and the operating system initialization function at the same time.

[0062] refer to Figure 4 , Figure 4 A specific flow chart is shown for modifying the source code implementing the hardware initialization function in the hardware configuration source file based on the source code implementing the operating system initialization function in the operating system source file according to an embodiment of the present application, which may specifically include steps S410 to S430, as described in detail as follows.

[0063] In step S410, source code for implementing a suspendable exception interrupt function and source code for implementing a system clock interrupt function are determined in the hardware configuration source file.

[0064] In one embodiment, in order to modify the source code that implements the hardware initialization function in the hardware configuration source file based on the source code that implements the operating system initialization function in the operating system source file, in the hardware configuration source file, it is necessary to separately determine the source code that implements the suspendable exception interrupt function and the source code that implements the system clock interrupt function.

[0065] Specifically, it is possible to find a source file containing source code for implementing a suspendable exception interrupt function and a source file containing source code for implementing a system clock interrupt function from the hardware configuration source file according to the file name of the source file, and further obtain the source code for implementing the suspendable exception interrupt function and the source code for implementing the system clock interrupt function from the multiple corresponding source files found.

[0066] In step S420, source code for implementing the multi-task interrupt function and source code for implementing the system clock interrupt function are determined in the operating system source file.

[0067] In one embodiment, in order to modify the source code that implements the hardware initialization function in the hardware configuration source file based on the source code that implements the operating system initialization function in the operating system source file, in the operating system source file, it is necessary to separately determine the source code that implements the multi-tasking interrupt function and the source code that implements the system clock interrupt function.

[0068] Specifically, it is possible to find a source file containing source code for implementing a multi-tasking interrupt function and a source file containing source code for implementing a system clock interrupt function from the operating system source file according to the file name of the source file, and further obtain the source code for implementing the multi-tasking interrupt function and the source code for implementing the system clock interrupt function from the found source file.

[0069] In step S430, the source code for implementing the suspendable exception interrupt function in the hardware configuration source file is replaced based on the source code for implementing the multi-tasking interrupt function in the operating system source file, and the source code for implementing the system clock interrupt function in the hardware configuration source file is replaced based on the source code for implementing the system clock interrupt function in the operating system source file.

[0070] In one embodiment, after determining the above-mentioned source code, the source code in the operating system source file for implementing the multi-tasking interrupt function is replaced by the source code in the hardware configuration source file for implementing the suspendable exception interrupt function, and the source code in the operating system source file for implementing the system clock interrupt function is replaced by the source code in the hardware configuration source file for implementing the system clock interrupt function, so that the terminal device can realize the multi-tasking function, and then the interrupt function of the terminal device is applicable to the case where there is an operating system.

[0071] exist Figure 4 In the technical solution of the illustrated embodiment, by automatically modifying the source code for implementing the interrupt function in the hardware configuration source file with the source code for implementing the interrupt function in the operating system source file, it is possible to make the interrupt function of the terminal device adapt to the situation of having an operating system without the involvement of developers, which can effectively reduce the workload of developers and improve the efficiency of operating system transplantation for terminal devices.

[0072] refer to Figure 5 , Figure 5 A specific flow chart is shown for modifying the source code implementing the hardware initialization function in the hardware configuration source file based on the source code implementing the operating system initialization function in the operating system source file according to an embodiment of the present application, which may specifically include steps S510 to S530, as described in detail as follows.

[0073] In step S510, in the operating system source file, the header file reference source code for implementing data calls in the operating system, the interface function source code for implementing the operating system calling the application program interface of the micro control unit, and the entry function source code for implementing the operating system initialization function are determined.

[0074] In one embodiment, in order to modify the source code that implements the hardware initialization function in the hardware configuration source file based on the source code that implements the operating system initialization function in the operating system source file, in the operating system source file, it is necessary to separately determine the header file reference source code that implements data calls in the operating system, the interface function source code when the operating system calls the application program interface of the microcontroller unit, and the entry function source code that implements the operating system initialization function.

[0075] Specifically, it is possible to find a source file containing header file reference source code, a source file containing interface function source code, and a source file containing entry function source code from the operating system source files according to the file name of the source file, and further obtain the header file reference source code, interface function source code, and entry function source code from the multiple corresponding source files found.

[0076] In step S520, source code for implementing a hardware initialization function is determined in the hardware configuration source file.

[0077] In one embodiment, in order to modify the source code implementing the hardware initialization function in the hardware configuration source file based on the source code implementing the operating system initialization function in the operating system source file, the source code implementing the hardware initialization function needs to be determined separately in the hardware configuration source file.

[0078] Specifically, the source file of the source code for implementing the hardware initialization function may be found from the operating system source file according to the file name of the source file, and the source code for implementing the hardware initialization function may be further obtained from the found multiple corresponding source files.

[0079] In step S530, based on the header file reference source code, the interface function source code and the entry function source code, the source code for implementing the hardware initialization function in the hardware configuration source file is modified.

[0080] In one embodiment, after the source code is determined, modification processing can be performed. Specifically, new source code is inserted into the source code that implements the hardware initialization function in the hardware configuration file, replacing the existing source code in the hardware configuration file.

[0081] refer to Figure 6 , Figure 6 A specific flow chart of step S530 according to an embodiment of the present application is shown, which may specifically include steps S610 to S630, which are described in detail as follows.

[0082] In step S610, a header file reference source code is inserted into the source code for implementing the hardware initialization function in the hardware configuration source file.

[0083] In one embodiment, by inserting a header file reference source code into a source code used to implement a hardware initialization function in a hardware configuration source file, a function of making a data call in an operating system through an application program interface is implemented.

[0084] In step S620, based on the interface function source code, the interface function source code for implementing the call to the micro control unit in the hardware configuration source file is packaged to generate a packaged interface function source code.

[0085] In one embodiment, the entry function source code in the hardware configuration source file for implementing the hardware initialization function is encapsulated based on the entry function source code to generate an encapsulated interface function source code, so that the terminal device can call various hardware interfaces on the terminal device according to the new interface function, such as the various interfaces on the microprocessor unit and the interfaces on the various peripheral hardware devices controlled by the microprocessor unit.

[0086] In step S630, based on the entry function source code, the entry function source code implementing the hardware initialization function in the hardware configuration source file is encapsulated to generate encapsulated entry function source code.

[0087] In one embodiment, the entry function source code in the hardware configuration source file for implementing the hardware initialization function is encapsulated based on the entry function source code to generate encapsulated entry function source code, so that the terminal device can simultaneously perform hardware initialization and operating system initialization.

[0088] exist Figure 5 and Figure 6In the technical solution of the illustrated embodiment, the source code used to implement the hardware initialization function in the hardware configuration source file is modified by referencing the source code, the interface function source code, and the entry function source code, thereby achieving the goal of enabling the terminal device to simultaneously perform hardware initialization and operating system initialization without the involvement of developers, which can effectively reduce the workload of developers and improve the efficiency of operating system transplantation for terminal devices.

[0089] Please continue to refer to Figure 2 In step S230, the operating system engineering file and the hardware engineering file are merged to generate a merged engineering file.

[0090] In one embodiment, after modifying the logic layer source code in the hardware configuration source file based on the logic layer source code in the operating system source file and generating the modified source file, the operating system project file and the hardware project file can be combined to generate a merged project file.

[0091] In step S240, the modified source file is compiled based on the merged project file to generate a compiled file.

[0092] In one embodiment, after obtaining the merged project file, the modified source file is compiled based on how to compile the source code indicated by the merged project file to generate a compiled file. It can be understood that the generated compiled file is a binary file that can be burned.

[0093] In step S250, a program is burned based on the compiled file, and the burned program is imported into the memory of the micro control unit.

[0094] In one embodiment of the present application, a program is burned based on a compiled binary file, and the burned program is imported into the memory of the microcontroller unit, thereby implementing the transplantation of the operating system into the microprocessor unit of the terminal device.

[0095] From the above, it can be seen that the modified source files are compiled based on the merged project files to generate compiled files, so that when the operating system is transplanted, there is no need for developers to have a high level of professionalism in the technical level of the operating system, and there is no need for developers to do a lot of software development to automatically transplant the operating system to the Internet of Things terminal, which reduces the complexity of operating system transplantation and improves the efficiency of operating system transplantation.
