The small board includes the circuit board corresponding to the bottom antenna, which can be used to transmit and receive electromagnetic wave signals.

In some implementations, the main board can be connected with at least one small board to be assembled into different electronic devices.

Therefore, when starting to detect whether the third small board is the target small board, it is necessary to power and start the first main board, so that the first operating system stored on the first main board starts to start, so as to perform subsequent processing.

In some implementations, the first mainboard is connected to the first display screen. When the first display screen displays the start-up picture, corresponding to the first main board being started up, the first operating system is started.

S502. The first operating system parses the device tree source file to obtain the first USID and the first MIPI interface address.

It should be noted that the electronic device also includes a MIPI module. In some implementations, the MIPI module can be configured on the first main board and/or the third small board. In some other implementations, the MIPI module may be independent of the first main board and the third small board, and be independently configured in the electronic device. The MIPI module includes at least one MIPI interface. Wherein, the at least one MIPI interface includes a first MIPI interface, and the first MIPI interface is preset with a first MIPI interface address. The first MIPI interface can be connected to device A, and device A is configured on the third small board. The first MIPI interface can be used to control the working mode of device A.

Exemplarily, a device tree source file is preset in the electronic device, and the device tree source file is used to describe information of hardware components in the electronic device. Wherein, the device tree source file includes a first USID and a first MIPI interface address, the first USID is used to identify the target small board, and the first USID corresponds to the first MIPI interface address.

It can be understood that the first operating system includes a kernel, and the kernel is used for process management, memory management, device management, file management, network management and so on. The process of starting the first operating system includes starting the kernel.

In some embodiments, the first operating system may parse the device tree source file through the kernel to obtain the first USID and the first MIPI interface address corresponding to the first small board during the kernel startup phase.

It should be noted that before performing the operation of S502, S503 may be executed first to configure the first USID and the first MIPI interface in the device tree source file. This facilitates the first operating system to obtain the first USID and the first MIPI interface address from the device tree source file for subsequent processing.

S503. Configure the first USID and the first MIPI interface address corresponding to the first small board in the device tree source file.

Exemplarily, the first USID corresponding to the first board and the first MIPI interface address may be configured in the first device node in the device tree source file. Wherein, the device tree source file may be stored in the memory. In this way, when the first operating system executes the operation of S502, it can obtain the device tree source file from the memory, and parse the first device node in the device tree source file through the kernel to obtain the first USID corresponding to the first small board. , and the address of the first MIPI interface.

In the descriptions of S502 and S503, the device tree source file is used as an example for description. In other embodiments of the present application, other forms of text files can also be used to describe the first The USID and the first MIPI interface address are convenient for reading the first USID and the first MIPI interface address from the text file during subsequent use.

In the embodiment of the present application, before determining whether the third small board is the target small board, the first operating system may first perform the operation of S504 to obtain the second USID corresponding to the first MIPI interface on the third small board, Then compare the second USID with the first USID obtained in S502, and then determine whether the third small board is the target small board.

S504. The first operating system determines the second USID of the third small board according to the first MIPI interface address.

Exemplarily, the first MIPI interface address may be resolved by the first operating system from the device tree source file in S503. In other implementations, the first MIPI interface address may also be directly written into the first program of the first operating system. In this way, when the first MIPI interface address needs to be used subsequently, the first operating system can acquire the first MIPI interface address from the first program.

After obtaining the first MIPI interface address, the first operating system may determine the second USID corresponding to the third small board according to the first MIPI interface address.

In the specific implementation of the embodiment of the present application, with reference to the description of FIG. 3 , the function of the first operating system is implemented on the application processor, and the function of the third small board is implemented on the first modem. The second USID corresponding to the first MIPI interface on the third small board can be obtained from the first modem. Therefore, when the first operating system obtains the second USID, it also needs to perform information interaction with the first modem corresponding to the third small board.

Exemplarily, as shown in FIG. 6, the first operating system may exchange information between the wireless interface layer in FIG. 4 and the first modem in the hardware layer, so that the first operating system acquires A second USID corresponding to the MIPI interface address.

As shown in Figure 6, the program includes:

S601. The first operating system sends a first AT command to the first modem through the wireless interface layer.

In this example, the starting process of the first operating system also includes starting the wireless interface layer. After the wireless interface layer is fully started, the first operating system may send a first attention (Attention, AT) command to the first modem through the wireless interface layer. Wherein, the parameters of the first AT command include the address of the first MIPI interface. The first AT command is used to obtain the second USID corresponding to the first MIPI interface on the third board. In other embodiments of the present application, the first AT command may also be called the first command.

It can be understood that the first AT command is a command that the first modem can parse and execute.

S602. The first modem parses the first AT command to acquire the second USID.

Exemplarily, after receiving the first AT command, the first modem parses the first AT command to obtain the address of the first MIPI interface. The first modem obtains the second USID corresponding to the first MIPI interface address on the third board according to the first MIPI interface address.

In this example, after the first modem acquires the second USID, it may perform operation S603 to send the second USID to the wireless interface layer.

S603. The first modem sends the second USID to the wireless interface layer.

In this example, after completing the operation of S602, the first modem sends the obtained second USID to the wireless interface layer as a response to the first AT command. After receiving the second USID, the wireless interface layer executes the operation of S604.

S604. The wireless interface layer configures the second USID into the first register.

Exemplarily, after receiving the second USID, the wireless interface layer may configure the USID in the first register. Wherein, the first register is a register inside the application processor, and the first register corresponds to the first address. The first operating system can read data from the first register.

As an implementation manner, the wireless interface layer may configure the second USID into the first register through an input/output control (Input/OutputControl, IOCTL) interface.

S605. The first operating system sends a first instruction to the wireless interface layer.

Exemplarily, the first system may send the first instruction to the wireless interface layer through the kernel after the kernel finishes booting. The first instruction is used to acquire the first address corresponding to the first register in S604. In other embodiments of the present application, the first instruction may also be called a second command.

S606. The wireless interface layer returns the first address corresponding to the first register to the first operating system.

Exemplarily, after receiving the first instruction in S605, the wireless interface layer sends the first address corresponding to the first register to the first operating system.

S607. Read the second USID according to the first address corresponding to the first register.

Exemplarily, after receiving the first address corresponding to the first register sent by the wireless interface layer, the first operating system reads the second USID stored in the first register according to the first address.

It should be noted that, in the embodiment of the present application, during the process of starting the first operating system on the first motherboard, the time when the wireless interface layer finishes starting is earlier than the time when the kernel finishes starting. Therefore, before the first operating system performs the operation of S605, the wireless interface layer has configured the second USID into the first register.

In the above example, the configuration of the second USID in the first register is taken as an example for illustration. In some other embodiments of the present application, the wireless interface layer may store the received second USID in a memory. The first operating system may obtain the second USID from memory.

In this way, through the method shown in FIG. 6 , the first operating system can obtain the second USID corresponding to the first MIPI interface on the third board through the kernel. After the first operating system acquires the second USID, it continues to perform subsequent processing to determine whether the third small board is the detection result of the target small board.

S505. The first operating system determines a matching identifier according to the second USID and the first USID.

Exemplarily, the first operating system compares the read second USID corresponding to the third small board with the first USID in the device tree source file, and determines whether the second USID is consistent with the first USID. Whether the platelet is the target platelet.

In some embodiments, the first operating system may indicate whether the third small board is the target small board by setting a value of the matching flag. The value of the matching identifier includes the first value or the second value. Wherein, the first value corresponds to that the second USID is consistent with the first USID, which means that the third small plate is the target small plate. The second value corresponds to that the second USID is inconsistent with the first USID, that is, it indicates that the third small board is not the target small board.

Exemplarily, the first operating system may set the matching identifier as the first value according to the second USID being consistent with the first USID, so as to indicate that the third small board is the target small board. In some implementations, the first value may be "1."

In some other implementations, according to the fact that the second USID is not consistent with the first USID, the first operating system may set the matching flag as the second value, to indicate that the third small board is not the target small board. In some implementations, the second value may be "0".

As an implementation manner, the first operating system may continue to perform the operation of S507 after setting the value of the matching identifier to the first value and/or the second value.

In this embodiment, before performing the operation of S507, the first operating system may execute the operation of S506 to create a first storage node in the memory to store the detection result of whether the third small board is the target small board.

S506. The first operating system creates a first storage node.

Exemplarily, the first storage node is used to store the detection result of whether the third small board is the target small board. The data in the first storage node is stored on the memory. When creating the first storage node, the first operating system may name the first storage node with the first name. In this way, it is convenient to index to the first storage node according to the first name when the data in the first storage node needs to be read later.

As an implementation manner, the creation of the first storage node by the first operating system may be performed before operation of S505. For example, when the first mainboard starts to start, the first operating system executes the operation of S506 to create the first storage node.

As another implementation manner, the creation of the first storage node by the first operating system may also be performed after performing the operation of S505.

In some embodiments, after completing the creation of the first storage node, the first operating system may execute the operation of S507 to store the matching identifier in S505 in the first storage node.

S507. The first operating system stores the matching identifier in the first storage node.

In some implementations, the first operating system may store the first value in the first storage node, so as to facilitate subsequent reading of the detection result that the third small board is the target small board from the first storage node.

In some other implementations, the first operating system may store the second value in the first storage node, so as to facilitate subsequent reading of the detection result that the third small board is not the target small board from the first storage node.

In some other embodiments of the present application, after performing the operation of S505, the first operating system may store the value corresponding to the matching identifier at the third address of the memory. In order to obtain the value corresponding to the matching identifier from the third address of the memory in subsequent processing.

For example, the first operating system may store the first value of the matching identifier in a third address of the memory, so as to facilitate subsequent reading of the detection result that the third small board is the target small board from the third address of the memory.

For another example, the first operating system may store the second value of the matching identifier in the third address of the memory, so as to facilitate subsequent reading of the detection result that the third small board is not the target small board from the third address of the memory.

In the embodiment of the present application, through the operations from S501 to S507, the first operating system obtains the first USID and the first MIPI interface address from the first device node in the device tree source file, and according to the first MIPI interface address, Obtain the second USID from the first modem corresponding to the third small board. According to whether the first USID is consistent with the second USID, the first operating system determines the value of the matching flag to indicate whether the third small board is the target small board, and stores the value of the matching flag in the memory. Furthermore, the determination of the detection result of whether the third small plate is the target small plate is completed.

In some other embodiments of the present application, referring to FIG. 7 , it is taken that the detection result is stored in the first storage node as an example. After the electronic device completes the determination of the detection result of whether the third small board is the target small board, the display unit may obtain the detection result indicated by the matching identifier in the first storage node, and display the detection result. Wherein, the display unit may include a display unit A or a display unit B. The display unit A is connected to the electronic device, and the display unit B is configured in the electronic device. In other embodiments of the present application, the display unit A may also be called the second display unit, and the display unit B may also be called the first display unit.

The following describes in detail how the display unit A obtains the detection result and displays the detection result with reference to the accompanying drawings.

Exemplarily, when the first mainboard is powered on, the first operating system running on the first mainboard may read the matching identifier from the first storage node. The first operating system sends corresponding prompt information to the display unit A according to whether the matching identifier read from the first storage node includes the first value or the second value. After receiving the prompt information, the display unit A displays the prompt information. Wherein, the prompt information includes first prompt information or second prompt information. The first prompt information is used to indicate that the third small plate is the target small plate, and the second prompt information is used to indicate that the third small plate is not the target small plate.

It can be understood that, in some specific implementations, when the first operating system performs the operation of obtaining the matching identifier from the first storage node, it also needs to retrieve the first storage node. When the creation of the first storage node fails, the first operating system cannot retrieve the first storage node, that is, the first storage node does not exist. As a result, the first operating system cannot obtain the matching identifier.

Therefore, in some other implementations of the present application, the prompt information may further include third prompt information, where the third prompt information is used to indicate that the creation of the first storage node fails. The first operating system sends third prompt information to the display unit A when the first storage node does not exist.

As an implementation manner, referring to FIG. 8 , the display unit A includes a USB driver. When the display unit A is connected to the first main board through a USB data cable, and the first main board is powered on normally, the display unit A can identify, manage and control the first main board through the USB driver. Furthermore, the display unit A and the first motherboard can exchange information through the USB driver, and execute the processing shown in FIG. 8 .

It can be understood that, when performing the operations shown in FIG. 8 , the display unit A is connected to the first main board through a USB data cable, and the first main board is in a normal power-on state.

As shown in Figure 8, the program includes:

S801. The display unit A sends a second AT command to the first main board.

Exemplarily, after the display unit A is connected to the first motherboard through the USB data cable, the USB driver will provide the first USB interface. The display unit A can send the second AT command to the first motherboard through the first USB interface. Wherein, the second AT command is used to acquire prompt information. In some other embodiments of the present application, the second AT command may also be called a third command.

As an implementation manner, an application A is installed on the display unit A. The application A can realize that the display unit A sends the second AT command to the first motherboard through the first USB interface. The second AT command may be displayed on the user interface corresponding to application A. The display unit A may send the second AT command to the first motherboard through the application A under the instruction of the tester.

For example, referring to FIG. 9 , when the display unit A detects that the tester double-clicks the icon corresponding to the application A, it runs the application A and displays the first interface as shown in FIG. 9 . When the tester needs to set the interface number, he can click the first control on the first interface. Correspondingly, when the display unit A detects that the tester clicks on the first control, the interface number can be set as the first USB interface. In this way, the display unit A can send the second AT command to the first motherboard connected to the display unit A through the first USB interface.

Wherein, the first interface further includes a first area, and the first area is used for the display unit A to send the second AT command.

Specifically, the display unit A may input the second AT command on the first area under the instruction of the tester. When the display unit A detects that the tester clicks on the second control on the first interface, it can send the second AT command input in the first area to the first motherboard connected to the display unit A through the first USB interface.

In this embodiment, after receiving the second AT command, the first operating system running on the first motherboard starts to perform the following processing:

S802. When receiving the second AT command, index the first storage node.

It can be understood that, before obtaining the matching identifier stored in the first storage node, the first operating system needs to index to the first storage node.

With reference to the foregoing description, the first operating system names the first storage node a first name. After the first motherboard receives the second AT command sent by the display unit A, the first operating system can index to the first storage node according to the first name.

S803. Determine whether to index to the first storage node.

In some implementations of the present application, if the creation of the first storage node fails, the first operating system cannot index the first storage node. Therefore, the first operating system also needs to determine whether to index to the first storage node.

As an implementation manner, the first operating system continues to perform the operation of S804 when indexing to the first storage node.

As another implementation manner, when the first operating system fails to index the first storage node, it indicates that the first storage node does not exist. The first operating system can perform the operation of S808.

S804. Read the matching identifier stored in the first storage node.

Exemplarily, after indexing to the first storage node, the first operating system starts to read the matching identifier stored in the first storage node. After the first operating system finishes reading the matching identifier stored in the first storage node, it can continue to perform subsequent processing.

As an implementation manner, the first operating system may send the read matching identifier to the display unit A after reading the matching identifier stored in the first storage node. Display unit A displays the matching identification.

As another implementation manner, after the operation of S804 is completed, the first operating system may judge the read matching identifier. According to whether the read matching identifier includes the first value or the second value, the first operating system generates corresponding prompt information and sends it to the display unit A. The display unit A displays the prompt information. The specific operation is as follows:

S805. Determine whether the matching identifier includes the first value.

In some implementations, when the first operating system determines that the read matching identifier includes the first value, the operation of S806 is continued.

In some other implementations, when the first operating system determines that the read matching identifier does not include the first value, the operation of S807 is continued.

It should be noted that, in the description of S805, the first operating system performs the judgment on whether the matching identifier includes the first value as an example. With reference to the foregoing description, the first matching identifier includes the first value or the second value. Therefore, in some other embodiments of the present application, the first operating system may also send corresponding prompt information to the display unit A according to whether the matching identifier includes the second value.

S806. Send the first prompt information to the display unit A.

Exemplarily, the first operating system sends the first prompt information to the display unit A in the case of judging that the read matching identifier includes the first value.

For example, the first operating system sends the first prompt information to the display unit A through the first USB interface in the case of performing the operation of S804 and judging that the read matching identifier includes the first value. Wherein, the first prompt information may include a first value of the matching identifier. The first value corresponds to the third platelet being the target platelet.

S807. Send the second prompt information to the display unit A.

Exemplarily, when the first operating system executes the operation of S805 and judges that the read matching identifier does not include the first value, that is, when the matching identifier includes the second value, it sends the second prompt information to the display unit A .

For example, when the first operating system determines that the read matching identifier does not include the first value, it sends the second prompt information to the display unit A through the first USB interface. Wherein, the second prompt information may include a second value of the matching identifier. The second value corresponds to the third platelet being not the target platelet.

S808. Send the third prompt information to the display unit A.

Exemplarily, the first operating system sends the third prompt information to the display unit A when the operation of S802 is not found in the index.

For example, the first operating system sends the third prompt information to the display unit A through the first USB interface when the first storage node cannot be indexed. The third prompt information is used to indicate that the creation of the first storage node fails.

In the above example, after receiving the second AT command sent by the display unit A, the first operating system reads the matching identifier from the first storage node through the operations from S802 to S808. The first operating system returns corresponding prompt information to the display unit A through the first USB interface according to whether the matching identifier includes the first value or the second value. After receiving the prompt information, the display unit A may continue to perform the processing from S809 to S811 to display the prompt information.

In some implementations, referring to FIG. 9 , the first interface corresponding to application A further includes a second area, and the second area is used to display the prompt information received by display unit A. After receiving the prompt information returned by the first operation, the display unit A may display the prompt information on the second area of the first interface.

S809. The display unit A displays the first prompt information.

Exemplarily, after the display unit A receives the first prompt information sent by the first operating system, the second area in FIG. 9 may display the first prompt information.

For example, taking the first prompt information including "PASS" as an example, as shown in FIG. 10 , after the display unit A receives the first prompt information, application A may correspond to a second interface as shown in FIG. 10 . The first prompt information is correspondingly displayed on the second area of the second interface to indicate that the third small board is the target small board. In this way, the user can determine the third small board as the target small board according to the first value of the matching identifier, which facilitates subsequent testing and processing.

S810. The display unit A displays the second prompt information.

Exemplarily, after the display unit A receives the second prompt information sent by the first operating system, the second area in FIG. 9 may display the second prompt information. For example, the first prompt information may include "FAIL". In this way, the user can determine that the third small plate is not the target small plate according to the second prompt information, which facilitates subsequent processing.

S811. The display unit A displays third prompt information.

Exemplarily, after the display unit A receives the third prompt information sent by the first operating system, the second area in FIG. 9 may display the third prompt information. For example, the third prompt information may include "ERROR". In this way, the user can determine that the creation of the first storage node fails according to the third prompt information, which facilitates subsequent debugging.

In the example of FIG. 8, when the display unit A is physically connected to the first motherboard through the USB matching identification line, and the first motherboard is turned on, the first USB interface provided by the USB driver in the display unit A displays Unit A sends a second AT command to the first motherboard. After receiving the second AT command sent by the display unit A, the first operating system in the first motherboard returns corresponding prompt information to the display unit A according to the solution in FIG. 8 . After receiving the prompt information, the display unit A displays the prompt information to indicate whether the third small plate is the detection result of the target small plate.

The above example is only a possible implementation manner, and the display unit A needs to be connected to the first main board through a USB data cable to realize information exchange between the first main board and the display unit A. Furthermore, the display unit A acquires the prompt information sent by the first main board, and displays the prompt information. In some implementations, the display unit A may be an assembly device, and the assembly device is connected to the first main board to perform the above examples.

In some other embodiments of the present application, the display of the detection result can also be realized through the display unit B, and the display unit B includes a first main board and a first display screen. The first main board obtains the detection result in FIG. 5 through the first control interface, and displays corresponding prompt information on the first display screen to indicate whether the third small board is the detection result of the target small board. That is to say, the function corresponding to the display unit B can be realized by the first main board and the first display screen.

Exemplarily, referring to FIG. 11 , the first mainboard is connected to a first display screen, and the first display screen displays application B installed on the first mainboard. The application B includes a first control interface. When the first operating system detects the operation of clicking the application B, it can read the matching identifier in the first storage node through the first control interface. And according to whether the read matching identifier includes the first value or the second value, corresponding prompt information is displayed on the first display screen. In other embodiments of the present application, application B may also be called the first application.

With reference to the foregoing description, the prompt information includes one of first prompt information, second prompt information, and third prompt information. The first prompt information is used to indicate that the third small board is the target small board, the second prompt information is used to indicate that the third small board is not the target small board, and the third prompt information is used to indicate that the creation of the first storage node fails.

As shown in Figure 11, the program includes:

S1101. Input a first operation.

Exemplarily, the first operation corresponds to clicking the application B, so that the first operating system starts to execute subsequent processing through the first control interface.

For example, referring to FIG. 11 , the tester may click the icon 101 on the first display screen to input the first operation.

In this embodiment, when the first operation is detected, the first operating system starts to perform the following processing:

S1102. When the first operation is detected, index the first storage node.

It can be understood that, before obtaining the matching identifier stored in the first storage node, the first operating system needs to index to the first storage node.

With reference to the foregoing description, the first operating system names the first storage node a first name. When the first operating system detects the operation of clicking the application B, it may index to the first storage node according to the first name.

S1103. Determine whether to index to the first storage node.

With reference to the description of FIG. 8 , failure to create the first storage node will cause the first operating system to fail to index the first storage node. Therefore, the first operating system also needs to determine whether to index to the first storage node.

As an implementation manner, the first operating system continues to perform the operation of S1104 when indexing to the first storage node.

As another implementation manner, when the first operating system fails to index the first storage node, it indicates that the first storage node does not exist. The first operating system can perform the operation of S1108.

S1104. Read the matching identifier stored in the first storage node.

Exemplarily, after indexing to the first storage node, the first operating system starts to read the matching identifier stored in the first storage node.

As an implementation manner, the first operating system may directly display the matching identifier on the first display screen after reading the matching identifier stored in the first storage node.

As another implementation manner, after the operation of S1104 is completed, the first operating system may judge from the read matching identifiers to matching identifiers. The first operating system generates corresponding prompt information according to whether the read matching identifier includes the first value or the second value, and displays the prompt information on the first display screen. The specific operation is as follows:

S1105. Determine whether the matching identifier includes the first value.

In some implementations, when the first operating system determines that the read matching identifier includes the first value, it continues to perform the operation of S1106.

In some other implementations, when the first operating system determines that the read matching identifier does not include the first value, it continues to perform the operation of S1107.

It should be noted that, in the description of S1105, the first operating system performs the judgment on whether the matching identifier includes the first value as an example. In some other embodiments of the present application, the first operating system may determine whether the matching identifier includes the second value. The first operating system displays corresponding prompt information on the first display screen according to whether the matching identifier includes the second value.

S1106. Display first prompt information on the first display screen.

Exemplarily, when the first operating system determines that the read matching identifier includes the first value, it displays the first prompt information on the first display screen connected to the first motherboard. Wherein, the first prompt information may include a first value of the matching identifier. The first value corresponds to the third platelet being the target platelet.

For example, taking the first prompt information including "PASS" as an example, on the interface 102 shown in Figure 12, the first display screen will display the test results of multiple test items. The multiple test items include test item 1, test item 2 and so on. Wherein, test item 1 corresponds to whether the third small plate is the target small plate. In the case where the first operating system determines that the read matching identifier includes the first value, interface 102 in FIG. 12 may display the first prompt information. In this way, the inspector can determine the third small plate as the target small plate according to the first prompt information, which facilitates subsequent testing and processing.

S1107. Display second prompt information on the first display screen.

Exemplarily, when the first operating system executes the operation of S1104 and judges that the read matching identifier does not include the first value, that is, when the matching identifier includes the second value, the first operating system executes the operation on the first motherboard. A second prompt message is displayed on the connected first display screen. Wherein, the second prompt information may include a second value of the matching identifier. The second value corresponds to the third platelet being not the target platelet.

For example, taking the second prompt message including "FAIL" as an example, in combination with the foregoing description, on the interface 103 shown in FIG. 13 , test item 1 corresponds to whether the first main board and the third small board are matched correctly. In the case where the first operating system judges that the read matching identifier does not include the first value, interface 103 in FIG. 13 may display the second prompt information. In this way, the inspector can determine that the third small board is not the target small board according to the second prompt information, and instruct to suspend the subsequent test of the test item.

S1108. Display third prompt information on the first display screen.

Exemplarily, the first operating system displays third prompt information on a display screen connected to the first mainboard when the operation of S1102 is performed and the first storage node cannot be indexed. Wherein, the third prompt information may include a third value. The third value corresponds to failure to create the first storage node.

For example, taking the third prompt message including "ERROR" as an example, combined with the foregoing description, on the interface 104 shown in FIG. 14 , test item 1 corresponds to whether the first main board and the third small board are matched correctly.
