Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The technical solution provided in the embodiment of the present application may be applied to configure a PCIE ID of a WWAN device, and therefore, a hardware operating environment corresponding to the technical solution is the WWAN device. WWAN equipment can be applied to notebook computers or other terminal equipment.
In the embodiments of the present application, the platform employed by the WWAN device may be a high-pass platform, or other platform. For a high-pass platform, in the startup phase of the device, the initialization process of the device includes: PBL (Primary Boot Loader), SBL (Secondary Boot Loader), UEFI, Linux Kernel, four-phase Boot programs.
The PBL is a program solidified in the chip of the device, and is used for initializing the device in an early stage, including initializing the PCIE bus, and the time required for execution does not exceed 100 milliseconds, so that the user cannot modify the code and configuration of the device.
The SBL is a boot procedure executed after the PBL is executed, and includes: power management module initialization, DDR (Double Data Rate) training, Flash initialization, and the like. The time required for execution does not exceed 500 milliseconds, and developers can add code at this stage to implement some configurations.
The UEFI program and the Linux Kernel program are other starting programs behind the bootstrap program, and can respectively realize the starting of interfaces, kernels, drivers and the like, so that the starting of the whole equipment is finally completed.
Based on the introduction of the application scenario, please refer to fig. 1, which is a flowchart of a configuration method of a WWAN device according to an embodiment of the present application, where the configuration method includes:
step 110: after the device is started, the default PCIE ID is configured to the PCIE configuration space register.
Step 120: and reading the information stored in the FLASH by running a preset bootstrap program.
Step 130: and if the pre-configured PCIE ID is read in the FLASH, updating the default PCIE ID according to the pre-configured PCIE ID.
In the embodiment of the present application, compared with the prior art, the configuration of the PCIE ID is implemented by using a preset bootstrap program, and on one hand, the default PCIE ID is configured in the space register first. On the other hand, a preset bootstrap program is used to read whether a pre-configured PCIE ID exists, and if so, the default PCIE ID is updated based on the pre-configured PCIE ID. By adopting the mode, if a user has a configuration requirement, the PCIE ID needing to be configured can be stored in the FLASH in advance, and automatic configuration can be realized in the starting process of the WWAN equipment; if the user has no configuration requirement, the configuration value is not written in the FLASH, and the WWAN device may also adopt a default value as the corresponding configuration value. Therefore, the configuration method can improve the flexibility of PCIE configuration.
A detailed embodiment of the configuration method will be described next.
In step 110, the booting of the device refers to booting after the device is powered on, where the device is a WWAN device.
As an alternative embodiment, step 110 includes: the default PCIE ID is configured into the PCIE configuration space register through a preset bootstrap (different from the bootstrap in step 120).
The boot program used in step 110 may be the PBL described in the foregoing embodiment, i.e., the first-stage boot program. As can be seen from the foregoing description, the code of the PBL is fixed and cannot be modified. Thus, by running the PBL, a default PCIE ID (i.e., a fixed PCIE ID) can be configured into a PCIE configuration space register.
In some embodiments, the default PCIE ID may also be configured into the configuration space register in other manners, for example: the configuration is performed by a start program before the first boot program, which is not limited in the embodiment of the present application.
After the configuration of the default PCIE ID is completed in step 110, a preset boot program is executed in step 120.
The preset boot program may be the SBL described in the foregoing embodiment, that is, the second-stage boot program, and after the second-stage boot program is run, the FLASH is also correspondingly started, and data reading, data storage, and the like may be performed on the FLASH. In the preset boot program, a read function and a configuration function may be included.
As can be seen from the foregoing description, the code of the SBL is configurable and modifiable by developers. Therefore, a developer can add a read function of the memory and a configuration function of the PCIE ID to implement the configuration of the PCIE ID.
It can be understood that, based on the configuration method provided in the embodiment of the present application, if the user has a configuration requirement of the PCIE ID, the PCIE ID that needs to be configured may be written into the FLASH in advance, and if the user does not have the configuration requirement of the PCIE, the PCIE ID that needs to be configured may not be written into the FLASH.
For example: different WWAN device manufacturers may use their PCIE IDs as PCIE IDs to be configured.
Furthermore, in step 120, it is necessary to read the information stored in the FLASH and determine whether there is a pre-configured PCIE ID therein.
As an optional implementation, the configuration process of the PCIE ID includes: acquiring a configuration instruction transmitted by an upper computer; the configuration instruction comprises a PCIE ID to be configured; and storing the PCIE ID to be configured into the FLASH according to the configuration instruction.
In this embodiment, the user can write the PCIE ID to be configured into the FLASH through the upper computer. During application, a user first establishes a connection between the WWAN device and the upper computer, for example: and establishing connection between the WWAN equipment and the upper computer through the communication connecting line.
After the connection is established, the upper computer sends the configuration instruction to the WWAN equipment, the WWAN equipment receives the configuration instruction, and the PCIE ID to be configured is written into the FLASH based on the configuration instruction.
As an optional implementation, the instruction transmitted between the upper computer and the WWAN device is an AT instruction.
In the embodiment of the application, the configuration instruction of the upper computer is effectively issued through the AT instruction.
Of course, in actual application, other executable configuration instructions may be adopted, and are not limited herein.
As an optional implementation manner, storing the PCIE ID to be configured in the FLASH according to the configuration instruction includes: and writing the PCIE ID to be configured into the appointed partition of the FLASH according to the configuration instruction.
In this embodiment, assuming that the FLASH has a plurality of data partitions, and different data partitions are used for storing data of different types or different sizes, etc., a data storage partition of a PCIE ID may be specified for the FLASH. Further, when storing the PCIE ID to be configured, it is written into the designated partition.
In the embodiment of the application, the PCIE ID to be configured is written into the appointed partition, so that the configured PCIE ID is conveniently read in the starting process, and the starting efficiency and the configuration efficiency are improved.
By combining the introduction of the implementation mode of the configuration process of the PCIE ID, it can be seen that the PCIE ID to be configured is stored in the FLASH by transmitting the configuration instruction through the upper computer, so that flexible configuration of the PCIE ID is realized.
In addition to the above mentioned configuration manner of PCIE IDs, as another optional implementation manner, during the use process of the WWAN device, the PCIE IDs may also be configured. Specifically, a remote management platform of an operator (a network operator, such as mobile, internet, etc.) configures the PCIE ID during the operation of the wireless network. That is, the remote management platform of the operator issues configuration information (configuration instruction) to the WWAN device. Correspondingly, a program for processing configuration information (configuration instruction) may be built in the WWAN device, and the program can process the delivered configuration information to implement the configuration of the PCIE ID.
Introduction to an embodiment based on the configuration of PCIE ID, as an optional embodiment, step 120 includes: and reading the information in the appointed partition of the FLASH by running a preset bootstrap program.
In this embodiment of the present application, the preconfigured PCIE ID may be stored in the designated partition of the FLASH, and further, by reading information of the designated partition, the preconfigured PCIE ID is accurately searched.
In step 120, after the information stored in the FLASH is read, if the preconfigured PCIE ID is not read, the subsequent other startup procedures are continuously executed, that is, the default PCIE ID is not modified.
If the preconfigured PCIE ID is read, step 130 is executed to update the default PCIE ID according to the preconfigured PCIE ID.
It is understood that the preconfigured PCIE ID may be the same as or different from the default PCIE ID. If the same is the case, no modification is required; if not, then a modification is required.
Thus, as an alternative embodiment, step 130 includes: judging whether the pre-configured PCIE ID is consistent with the default PCIE ID; if not, the default PCIE ID is modified into the pre-configured PCIE ID.
In this embodiment, the pre-configured PCIE ID is compared with the default PCIE ID, and if the two are completely the same, the two are the same; otherwise, the two are not consistent.
Further, if the two are not consistent, the default PCIE ID may be replaced with a preconfigured PCIE ID.
If the two are consistent, the default PCIE ID is not modified.
In the embodiment of the application, whether the pre-configured PCIE ID is consistent with the default PCIE ID is determined, and if the pre-configured PCIE ID is not consistent with the default PCIE ID, the default PCIE ID is modified to the pre-configured PCIE ID; if the pre-configured PCIE ID is consistent with the default PCIE ID, the default PCIE ID does not need to be modified, and the flexible configuration of the PCIE ID is realized.
After performing step 130, the WWAN device completes the first and second phases of booting, and may continue to complete the booting of the entire device through other booting procedures. Therefore, as an optional implementation, the method further comprises: and running a UEFI program and a Linux Kernel program to finish the initialization of the equipment.
The UEFI program and the Linux Kernel program have been described in the foregoing application scenarios, and are not repeated here.
In addition, by adopting the configuration method of the embodiment of the application, before the device is started each time, if the device is required, the PCIE ID can be preset, and after the device is restarted, the preset PCIE ID can be configured through a starting program, so that the flexibility is high.
