[0041] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.

[0042] In the embodiments of the present application, it should be noted that, in this article, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0043] Moreover, the terms "comprises," "comprising," or any other variation thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0044] In addition, the "plurality" in the embodiments of the present application refers to two or more than two. In view of this, in the embodiments of the present application, "plurality" can also be understood as "at least two". "At least one" can be understood as one or more, for example, one, two or more. For example, including at least one means including one, two or more, and there is no limit on which ones are included. For example, including at least one of A, B and C, then A, B, C, A and B, A and C, B and C, or A, B and C can be included.

[0045] It should be noted that, in the embodiments of the present application, "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / ", unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0046] The present application embodiment provides a method for configuring a chip device tree file. Figure 1 A flowchart of a method for configuring a chip device tree file provided in an embodiment of the present application is shown. Figure 1 As shown, the configuration method of the chip device tree file includes:

[0047] Step S100: Generate an initial device tree file of the chip, and the configuration fields in the initial device tree file are configured as preset initial values. Optionally, the initial device tree file is a device tree file described by the designer according to the detailed information of the chip, and the device tree file is used as a template. The configuration fields in the device tree file used to represent the chip hardware information are configured as preset initial values, and the initial values ​​are usually used to indicate that the configuration fields are in an unavailable state.

[0048] It is understandable that, in the embodiment of the present application, the configuration fields of the device tree file are fields that describe the hardware characteristics of the chip, including but not limited to describing the peripherals (Peripheral) and other hardware resources on the chip. These configuration fields are used to help the operating system understand and configure the hardware devices.

[0049] Step S200: Map the configuration fields in the initial device tree file to the actual hardware information of the chip to generate a mapping file. Optionally, the configuration fields in the initial device tree file are used to describe the chip hardware characteristics, so the configuration fields in the initial device tree file correspond to the actual hardware information of the chip.

[0050] It is understandable that the mapping relationship between the configuration fields in the device tree file and the actual hardware information of the chip is determined by the designer. Under this premise, creating a mapping file containing this relationship is a conventional technical means for technical personnel in this field. Therefore, the specific creation process of the mapping file is not described in the embodiments of the present application.

[0051] Step S300: Obtain the actual hardware information of the chip corresponding to the configuration field to be configured in the initial device tree file from the mapping file. Optionally, the configuration method of the chip device tree file provided in the embodiment of the present application is automatically executed by software, wherein the initial device tree file and the mapping file are designed by the designer and read by the software, and when the software configures the device tree file, the software will directly execute step S300: Obtain the actual hardware information of the chip corresponding to the configuration field to be configured in the initial device tree file from the mapping file.

[0052] Exemplarily, when it is necessary to configure the configuration fields related to the peripherals in the device tree file, the software obtains the actual hardware information of the chip corresponding to each configuration field related to the peripherals from the mapping file one by one.

[0053] Step S400: Configure the configuration fields to be configured in the device tree file according to the configuration results of the actual hardware information of the chip corresponding to the configuration fields to be configured in the initial device tree file. Optionally, for a chip system environment with variable hardware parameters, when it is necessary to change the parameters of the actual hardware information of the chip, the software can modify the configuration fields in the device tree file according to the configuration results required by the user after obtaining the actual hardware information of the chip corresponding to the configuration fields to be configured in the initial device tree file.

[0054] In some embodiments, the chip device tree file configuration method provided in the embodiments of the present application is applied in a SOPC (System On a Programmable Chip) environment where chip hardware parameters are variable, and is used to generate a device tree file and to modify the value of the configuration field of the device tree file.

[0055] The configuration method of the chip device tree file provided in the embodiment of the present application only needs to create a mapping file of the configuration field of the device tree file and the actual hardware information of the chip. The mapping relationship between the configuration field of the device tree file and the actual hardware information of the chip obtained by the mapping file can realize the automatic modification of the device tree file by the software, which greatly improves the configuration efficiency of the device tree file. The solution is executed by software, which reduces labor costs. In addition, when the chip type changes, only the initial device tree file and the mapping file need to be modified accordingly to solve the adaptation problem caused by the chip type change, which further improves the scalability and maintainability of the configuration device tree file.

[0056] In some embodiments, Figure 2 Another flow chart of the configuration method of the chip device tree file provided in the embodiment of the present application is shown. Figure 2 As shown, step S200: mapping the configuration fields in the initial device tree file with the actual hardware information of the chip, the step of generating the mapping file includes:

[0057] Step S210: Generate a hardware description file of the chip based on the actual hardware information of the chip.

[0058] Step S220: Map the configuration fields in the initial device tree file and the configuration fields in the hardware description file to generate a preset mapping file.

[0059] The chip device tree file configuration method provided in the embodiment of the present application converts the actual hardware information of the chip into a hardware description file that can be recognized by software, and then a mapping file between the configuration fields in the initial device tree file and the configuration fields in the hardware description file can be established.

[0060] In some embodiments, in the configuration method of the chip device tree file of the embodiment of the present application, the hardware description file is a file in .xml format. Optionally, in an embedded system, the hardware information of the chip is usually described as a hardware description file for storage.

[0061] In some embodiments, in the configuration method of the chip device tree file in the embodiment of the present application, the hardware description file in the ".xml" format is generated by an embedded development tool.

[0062] In some embodiments, Figure 3 Another flow chart of the configuration method of the chip device tree file provided in the embodiment of the present application is shown. Figure 3 As shown, step S300: the step of obtaining the actual hardware information of the chip corresponding to the configuration field to be configured in the initial device tree file from the mapping file includes:

[0063] Step S310: Read the mapping file to obtain the configuration field in the hardware description file corresponding to the configuration field to be configured in the initial device tree file. Optionally, in the configuration method of the chip device tree file based on the above step S200, the mapping file is used to determine which configuration field in the hardware description file determines the value of the configuration field in the device tree, and to confirm the value of the configuration field in the device tree file through the value of the configuration field in the hardware description file.

[0064] In some embodiments, Figure 4 Another flow chart of the configuration method of the chip device tree file provided in the embodiment of the present application is shown. Figure 4 As shown, step S210: the step of generating a hardware description file of the chip based on the actual hardware information of the chip, further includes:

[0065] Configure the configuration fields in the hardware description file of the chip to the target value. Optionally, the target value is the hardware information that needs to be modified when the configuration method of the chip device tree file is currently executed, so that when the software reads the configuration fields in the hardware description file corresponding to the configuration fields to be configured in the initial device tree file, it can also read the value of the hardware information to be modified. Exemplarily, when it is necessary to configure the configuration fields related to the peripherals in the device tree file, the software obtains the values ​​of the configuration fields in the hardware description file corresponding to each configuration field related to the peripherals from the mapping file one by one, so as to modify the values ​​of the configuration fields related to the peripherals in the device tree file accordingly.

[0066] In some embodiments, Figure 5 Another flow chart of the configuration method of the chip device tree file provided in the embodiment of the present application is shown. Figure 5 As shown, step S400: the step of configuring the configuration fields to be configured in the device tree file according to the configuration results of the actual hardware information of the chip corresponding to the configuration fields to be configured in the initial device tree file, includes:

[0067] Step S410: if the configuration field in the hardware description file corresponding to the configuration field to be configured in the initial device tree file is obtained from the mapping file, the value of the configuration field in the initial device tree file is modified according to the target value of the configuration field in the hardware description file.

[0068] Step S420: If the configuration field in the hardware description file corresponding to the configuration field to be configured in the initial device tree file is not obtained from the mapping file, the value of the configuration field in the initial device tree file is maintained as a preset initial value.

[0069] Optionally, the hardware description file may only include the hardware information that needs to be configured, and when the hardware information to be configured is the same as the initial value of the configuration field in the initial device file, the hardware description file may not include the hardware information. In this way, when the software reads the mapping file, the game configuration field in the initial device tree file does not have the corresponding configuration field in the hardware description file.

[0070] Next, an example is given to illustrate the configuration method of the chip device tree file provided in the embodiment of the present application, taking the configuration of chip peripheral information in the SOPC environment as an example for explanation, and the specific scheme is as follows:

[0071] A device tree file is generated, wherein the device tree file at least includes peripheral fields corresponding to peripheral driver information supported by the chip, and the peripheral fields of the device tree file are all set to a disabled state.

[0072] Configure the hardware parameters in the embedded development tool according to the actual hardware information of the chip, and generate a hardware description file in .xml format that includes at least the chip peripheral information.

[0073] The mapping relationship between the configuration fields in the hardware description file and the peripheral fields in the device tree file is organized into a mapping file.

[0074] The software reads the mapping file, obtains the configuration field of the hardware description file corresponding to the peripheral field of the device tree file, and obtains the specific value of the configuration field of the hardware description file. Specifically, when there is no mapping of the field of a peripheral module in the device tree file in the hardware description file, the field remains in an unavailable state (disabled); conversely, when there is a mapping of the field of a peripheral module in the device tree file in the hardware description file, the peripheral field of the device tree file is modified according to the value of the configuration field of the hardware description file. For example, if the configuration field of the hardware description file is enabled, the value of the peripheral field of the device tree file is configured to be available (okay); if the configuration field of the hardware description file is disabled, the value of the peripheral field of the device tree file is configured to be unavailable (disabled).

[0075] It can be understood that the above is an example of configuring the chip peripheral information to illustrate the configuration method of the chip device tree file provided in the embodiment of the present application. In actual application, the configurable hardware information includes all hardware supported by the chip, such as the clock frequency of the chip hardware module, the interrupt of the hardware module, the layout of the hardware module and other parameters.
