[0020] Based on security requirements information, the corresponding memory range is determined, and a memory mapping file is generated, including the following steps: Based on security level information, the correspondence between multiple functional modules and memory ranges is determined, and a memory mapping file is generated based on the correspondence.

[0039] To make the technical solutions and advantages of this disclosure clearer, the embodiments and related technical content of this disclosure will be further described in detail below with reference to the accompanying drawings and text description. It should be understood that the embodiments described below are only used to explain the technical solutions of the embodiments of this disclosure and are not intended to limit more possible implementations of this disclosure.

[0040] It should be noted that relational terms such as "first" and "second" appearing in this document are used only to distinguish things, states, or actions, and do not necessarily indicate or imply relative importance or order. The terms "including," "comprising," or any other variations thereof are used to indicate non-exclusive inclusion, and the included objects may not be limited to those listed in this document. The terms "multiple" or other variations are used to indicate that the number of objects is two or more.

[0041] In a first aspect, embodiments of this disclosure provide a software configuration method. The software is complex device driver software in an automotive open system architecture, and the method can be applied to, for example... Figure 1 The application environment shown is as follows. Terminal 100 is equipped with a host computer configuration tool 110 and a script generation tool 120. Terminal 100 has a display screen and an input device. The host computer configuration tool 110 can generate a visual configuration interface displayed on the terminal 100's display screen. The input device can be an external keyboard, mouse, or touchpad, etc. Terminal 100 can be, but is not limited to, various personal computers, laptops, and tablets.

[0042] Applying software configuration methods Figure 1 Taking terminal 100 as an example, in some embodiments, such as Figure 2 As shown, the software configuration method includes steps S201 to S205 that can be executed by terminal 100. Each step is described in detail below.

[0043] Step S201: Obtain the function description information of the functions to be implemented by the software to be configured and the security requirement information indicating the security level of the software to be configured.

[0044] The functional description information can include the functional items to be implemented, such as analog signal sampling functions (e.g., voltage sampling, temperature sampling), input / output control functions, and high / low side control functions. A functional description is provided for one or more of the functions to be implemented. The security requirement information can include the security level information of the software to be configured. In some specific examples, the security level information can be the security level corresponding to the predefined kernel security management measures in the AUTOSAR architecture. The AUTOSAR architecture supports parallel computing through multi-core processors to achieve higher performance and stronger functions. Each kernel in the system can be defined using the AUTOSAR configuration tool, specifying its attributes and characteristics, including the security level corresponding to each kernel. By allocating functional requirements of different security levels to different kernels, data security can be improved. In other examples, the security level can be a level defined according to the safety classification standards in the automotive field. For example, it can include four levels with progressively higher security levels: A, B, C, and D. Different security levels correspond to different kernel ranges. For example, Level D has the highest security level and requires storage in a dedicated storage space of an independent kernel. Levels B and C can be stored in a secure interval based on a preset isolation region to achieve physical isolation from insecure code. Level A has the lowest security level and does not require special security management; it can be stored in a normal memory area.

[0045] Specifically, the functional description information and security requirements information of the software to be configured can be obtained online from the document management system that stores the project development requirements documents, or from the storage device that stores the project development requirements documents; no special restrictions are imposed here.

[0046] Step S202: Based on the function description information, determine the target component from the host computer configuration component library and generate a visual configuration interface that includes multiple configuration items corresponding to the target component.

[0047] The host computer configuration component library includes multiple components built during the configuration of historically complex device driver software. Configuration items are used by users to configure the functional parameters of the software to be configured. In some examples, configuration items can be in the form of drop-down list options or fill-in-the-box boxes.

[0048] In some specific examples, the components in the host computer configuration component library may include kernel configuration components for allocating kernels for variable data, module configuration components for dividing functional modules, and parameter configuration components for setting functional parameters. A type of configuration component may include one or more configuration items. For example, a kernel configuration component may include a kernel enabling configuration item for determining whether the kernel state is enabled, and a channel kernel allocation configuration item for allocating kernels to different channels. A module configuration component may include module division configuration items and module naming configuration items. In some specific examples, the components in the host computer configuration component library also include channel configuration components for defining channels. Channel configuration components may include channel naming configuration items, channel ID configuration items, etc.

[0049] Specifically, based on the functional description information, the target component is determined from the host computer configuration component library. This can be done by determining the content to be configured based on the functional keywords in the functional description information, and then determining the corresponding target component. A visual configuration interface is then generated based on the multiple configuration items corresponding to the target component.

[0050] In some specific examples, the functional description information includes various functional configuration information for the function implementation. There is a correspondence between the host computer configuration components and the software functional configuration information, and this correspondence is pre-recorded in terminal 100. Terminal 100 can determine the corresponding host computer configuration component, i.e., the target component, based on the functional configuration information involved in the functional description information. In other specific examples, the functional description information only includes basic functional items of the intended function. Determining the target component based on the functional description information may include the following steps: determining the entire process steps of function implementation based on the functional description information; and determining the target component corresponding to each step of the entire process from the host computer configuration component library based on the entire process steps.

[0051] Step S203: Generate a function configuration file based on the function parameter information entered in the visual configuration interface.

[0052] In some specific examples, the feature configuration file may include a feature configuration source file and a feature configuration header file. Specifically, the feature configuration file may be in CFG file format (a text file format used to store configuration information).

[0053] Specifically, the visual configuration interface includes multiple configuration items, and the host computer configuration tool 110 generates a function configuration file based on the function parameter information input by the user in each configuration item.

[0054] Step S204: Based on the security requirements information, determine the corresponding memory range and generate a memory mapping file.

[0055] Specifically, the script generation tool 120 can determine the memory range corresponding to the security level information based on the security requirement information, and generate a memory mapping file to represent the storage range information of the software to be configured.

[0056] In some embodiments, the software to be configured includes multiple functional modules that are intended to perform functions, and the security requirement information includes the security level information of the multiple functional modules in the software to be configured. Step S204 may include the following steps: determining the correspondence between the multiple functional modules and memory regions based on the security level information, and generating a memory mapping file based on the correspondence. Specifically, it may be based on the security level information and a preset storage mapping relationship table to determine the memory region corresponding to each functional module in the multiple functional modules, thereby obtaining the correspondence between the multiple functional modules and memory regions, and generating a memory mapping file. The storage mapping relationship table is used to record the correspondence between the security level of the functional modules and the memory regions.

[0057] In some specific embodiments, the security level information corresponding to each functional module may be the same or different. The script generation tool 120 determines the memory range corresponding to multiple functional modules based on the security level information of each functional module, obtains the correspondence between multiple functional modules and memory ranges, and generates a memory mapping file based on the correspondence.

[0058] In some specific examples, the script generation tool 120 can generate a memmap.h file (memmap header file) based on a memmap (Memory Mapping) script tool.

[0059] Step S205: Obtain the target configuration code data based on the function configuration file and memory mapping file, so that the vehicle controller can implement the function corresponding to the software to be configured.

[0060] The target configuration code data includes configuration code used to implement the intended functions of the software to be configured. Specifically, in some examples, the target configuration code data can be obtained by integrating the function configuration file and memory-mapped file into the code file that implements the software functions. This target configuration code data is used to implement the corresponding functions of the software to be configured.

[0061] In some embodiments, the software configuration method further includes the following steps: compiling the target configuration code data and writing it into the vehicle controller so that the vehicle controller can implement the functions corresponding to the software to be configured.

[0062] Specifically, the target configuration code data is compiled and processed by a compiler to generate an executable file. Then, a preset debugging tool is used to write the executable file into the car controller so that the car controller can run the software to be configured and perform the configured functions.

[0063] In the above software configuration method, the target component is determined from the host computer configuration component library based on the function description information, a visual configuration interface is generated, and a function configuration file is generated based on the function parameter information input in the visual configuration interface. Additionally, a memory mapping file is generated based on the memory range determined by the security requirements information. By reusing the host computer configuration components built in the historical software configuration process, a visual configuration interface with multiple configuration items is generated. These configuration items are used by the user to configure the function parameters of the software to be configured, replacing the traditional method of manually writing code to implement function configuration, thus improving software development efficiency. Generating a memory mapping file based on security requirements information enables automatic allocation of software memory ranges and avoids the problems of low development efficiency and high error risk associated with manual memory allocation by the user.

[0064] In addition, memory allocation based on security requirements fulfills the functional safety requirements of the software to be configured, ensuring data security during software operation.

[0065] In some embodiments, step S202 may include the following steps: determining the configuration information to be implemented based on the functional description information, determining the target component for configuring the configuration information from the host computer configuration component library, and generating a visual configuration interface including multiple configuration items corresponding to the target component.

[0066] In some embodiments, the components in the host computer configuration component library include dynamic components and static components. Dynamic components are used to implement the configurable functions of the software to be configured, while static components are used to implement data that cannot be modified during the operation of the software to be configured.

[0067] Configurable functions correspond to the variable function modules of the software, such as communication protocol parameters, specifications and models of configuration data, register address information, triggering conditions for business logic, threshold settings, etc. Unmodifiable data can be low-level basic functional data or core data that has been fixed before the software runs, such as hardware driver code data, pre-built resource file data, authentication and authorization security data, etc.

[0068] Step S202 may include: determining the target configurable component from the dynamic components based on the functional description information, and generating a visual configuration interface that includes multiple configuration items corresponding to the target configurable component.

[0069] Static components, as immutable data carriers, do not require user configuration. Therefore, the configuration items corresponding to static components no longer need to be displayed in the visual configuration interface, which simplifies the configuration interface.

[0070] Accordingly, the software configuration method also includes the following steps: generating a static configuration file based on the parameter information of the static components. In some specific examples, the static configuration file may be generated during the configuration of historically complex device driver software and can be directly called in the current configuration task.

[0071] Step S205 may include: obtaining target configuration code data based on the function configuration file, memory-mapped file, and static configuration file.

[0072] In some embodiments, the software to be configured includes multiple functional modules corresponding to the functions to be implemented. The software configuration method further includes the following steps: according to the kernel configuration information input by the configuration item corresponding to the kernel configuration component, the code data and variable data of the same functional module are assigned to the same kernel.

[0073] The kernel configuration information includes the mapping relationship between the variable data of each functional module and the kernel.

[0074] In some examples, in response to user input based on configuration items corresponding to kernel configuration components, the kernel configuration information corresponding to the input is identified, the target functional module and target kernel corresponding to the variable data in the kernel configuration information are determined, and the code data of the target functional module is allocated to the target kernel, so that the code data and variable data of the same functional module are allocated to the same kernel.

[0075] By allocating code data and variable data of the same functional module to the same kernel, the efficiency of data access and code execution during software operation can be improved.

[0076] In some embodiments, the complex driver module architecture corresponding to the software to be configured is as follows: Figure 3 As shown, it may include a communication layer 310, a functional layer 320 and an interface layer 330.

[0077] The communication layer 310 is used to enable communication and interaction between the complex driver module and external devices. The functional layer 320 is used to implement the functions corresponding to the target configuration code data. The interface layer 330 is used to enable data transfer between the functional layer and other software modules.

[0078] Step S205 may include: integrating the function configuration file and memory mapping file into the function layer of the preset complex driver module to obtain the target configuration code data.

[0079] In specific examples, taking the software to be configured, which includes the peripheral chip "ADI 2950," as an example, the peripheral chip communicates with the MCU (Microcontroller Unit) via a four-wire SPI (Serial Peripheral Interface). The ADI 2950's main function is signal sampling via its internal ADC. Specifically, the communication layer sends data via the SPI communication protocol, acting as a bridge between layers. The functional layer is responsible for implementing the specific functions of the peripheral chip and the specific operational steps for implementing those functions, such as acquiring the peripheral chip's input signals, including performing the following steps: requesting ADC conversion, delay processing, reading the result register data, and converting the register data into physical values. The interface layer is used to obtain the sampled physical values ​​obtained by the functional layer for use by other modules.

[0080] By abstracting complex driver modules into a three-layer architecture comprising a communication layer, a functional layer, and an interface layer, decoupling between software modules is achieved while increasing the clarity of the code architecture. This allows each layer to be interconnected yet easily decoupled for adaptation. For example, when other modules need to obtain physical values ​​collected by the complex driver module, they only need to call the API functions provided by the interface layer. Similarly, if the communication protocol needs modification, only the logic of the communication layer needs to be modified.

[0081] In some embodiments, the visual configuration interface includes multiple configuration items, which can be selected, dragged, or filled by the user to perform corresponding configuration operations. In some examples, the configuration items include multiple function parameter controls. In response to the user's drag operation on each function parameter control, the positional relationship of the function configuration code corresponding to each function parameter control can be changed.

[0082] In some embodiments, the software configuration method may further include the following steps: in response to an editing operation performed by a user on a specific component in a host computer configuration component library, changing the code data of the specific component.

[0083] In some embodiments, the visual configuration interface further includes configuration option controls for users to view the configuration component library, and the software configuration method may further include: in response to a user's selection operation of the configuration option controls, displaying configuration component information in the host computer configuration component library in the visual configuration interface.

[0084] By presenting all configuration component information in a visual configuration interface, users can add target components. It's easy to understand that all target components in the visual configuration interface are editable, allowing users to add, remove, or modify them as needed. This improves the flexibility of software configuration, enhancing both development efficiency and adaptability.

[0085] In some examples, the configuration items corresponding to the kernel configuration component may include multiple menu bars corresponding to multiple kernels of the system. For example, it may include four menu bars corresponding to kernel 0, kernel 1, kernel 2 and kernel 3 respectively. If it is determined from the functional description information that the Dio channel (Digital Input / Output Channel) controlling the high and low side switches needs to be assigned to kernel 0, the user can click on the menu bar of kernel 0 and add the channel definition code data in its content to complete the kernel configuration of the channel.

[0086] In some examples, the host computer configuration component library also includes an interface configuration component for implementing custom interface functions. This component includes API interface function configuration items and custom interface function configuration items. The API interface function configuration items allow users to confirm whether to use the default API interface functions, while the custom interface function configuration items are fill-in-the-blank boxes for users to input the code data corresponding to their custom interface logic, allowing for flexible configuration of interface functions according to user needs.

[0087] It should be understood that, although Figure 2 The steps in the flowchart are shown sequentially according to the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Figure 2 Unless otherwise expressly stated herein, the steps illustrated and other steps involved in the embodiments are not subject to strict order restrictions and may be performed in other orders. Furthermore, at least some steps in the foregoing embodiments may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but may be performed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but may be performed alternately or in turn with other steps or at least a portion of the sub-steps or stages of other steps.
