Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the following embodiments of the present invention are described in further detail with reference to the accompanying drawings.
It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are used for distinguishing two entities with the same name but different names or different parameters, and it should be noted that "first" and "second" are merely for convenience of description and should not be construed as limitations of the embodiments of the present invention, and they are not described in any more detail in the following embodiments.
The invention provides an efficient method for testing a bus interface of a BSP board card, and particularly refers to fig. 1.
Fig. 1 is a flowchart illustrating a method for testing a bus interface of a BSP board according to the present invention. As shown in fig. 1, the method for testing the bus interface of the BSP board card of the present invention includes: step S1, connecting a plurality of BSP boards to be tested to the same network through corresponding bus interfaces, and configuring a test instruction set in the BSP function packet of each BSP board; step S2, starting a plurality of BSP boards, loading an operating system, and sending a mode control instruction to the plurality of BSP boards; and step S3, controlling the plurality of BSP boards to establish communication connection based on the mode control instruction and the test instruction set, and communicating according to a preset interface configuration strategy to enable the plurality of BSP boards to perform interface test with each other.
According to the invention, the test instruction set is preset in the BSP function packet of the BSP board, so that the plurality of BSP boards can automatically establish communication connection and can be used as bus test equipment of the other side through mutual communication, thereby realizing batch test work of bus interfaces of the plurality of BSP boards at the same time and greatly improving the test efficiency of the bus interfaces of the BSP boards.
In one embodiment, for the step S1, a plurality of BSP boards are connected to the same network through corresponding bus interfaces; the network formed at this time is only one network with physical connection, and each BSP board in the network does not have communication capacity. The connection form of the network is not limited in the method of the present invention. For example, the form of the network may be as shown in fig. 2 or fig. 3; fig. 2 is a schematic structural diagram of a first embodiment of networking a plurality of BSP board cards to be tested according to the method of the present invention. Fig. 3 is a schematic structural diagram of a second embodiment of networking a plurality of BSP board cards to be tested according to the method of the present invention. Specifically, fig. 2 shows a network structure in which a plurality of BSP boards are connected to the same BSP board to form a network. Fig. 3 shows a network structure in which a plurality of BSP boards are connected in series in sequence to form a network.
In order to enable the BSP boards in the same network to be mutually used as "bus test equipment", communication connection among the BSP boards needs to be realized, so that feedback of communication interaction is utilized to check whether the data bus and the corresponding bus interface are normal. Therefore, in one implementation, the test instruction set is used to provide the virtual network card function, the proxy function, the interface configuration policy, and the MAC address for the corresponding BSP board; the MAC of each BSP board card is different from each other and is managed by the corresponding virtual network card function.
In further implementation, before formally performing the interface test, step S2 is further performed, the plurality of BSP boards are started and the operating system is loaded, and a mode control instruction is sent to the plurality of BSP boards; the method comprises the following specific steps: starting a plurality of BSP board cards and loading an operating system, sending a first mode control instruction to one of the BSP board cards, and sending a second mode control instruction to the other BSP board cards; the second mode control instruction includes the MAC address of the BSP board that is to receive the first mode control instruction. For example, in a specific embodiment, A, B, C, D, E five BSP boards need to be tested in batch, and a tester needs to determine a master BSP board first, where if B is selected as the master BSP board, the other A, C, D, E is selected as the slave BSP board; then, the tester needs to generate a first mode control instruction and a second mode control instruction respectively through an external device such as a computer, and presets the MAC address of the BSP board card B in the second mode control instruction; and then respectively send the first mode control instruction to the BSP board B, and send the second mode control instruction to the BSP boards A, C, D and E.
In a preferred embodiment, the test instruction set further includes functionality for identifying a specific USB device; on this basis, the first mode control instruction and the second mode control instruction may be stored in a designated USB device, for example, in a designated USB disk, when the designated USB disk is inserted into each BSP board, each BSP board will recognize the USB disk and automatically acquire the first mode control instruction or the second mode control instruction therein. The implementation method can greatly facilitate the field operation of testers, thereby improving the testing efficiency.
In a further embodiment, the step S3 of controlling the plurality of BSP boards to establish the communication connection based on the control command and the test command set includes: the agent function configures the BSP board receiving the first mode control instruction as a master control BSP board, and configures the BSP board receiving the second mode control instruction as a slave control BSP board; sending the MAC address of the slave BSP board card to the MAC address contained in the second mode control instruction through the virtual network card function and control; and the master control BSP board receives the MAC address of the slave control board through the virtual network card function, and establishes communication connection between the master control BSP board and the slave control BSP board. By the method, a plurality of BSP boards connected to the same network can realize automatic establishment of the communication network, and further batch test efficiency of the BSP boards is improved.
In a specific embodiment, the test instruction set in each BSP board further includes a broadcast forwarding function, and each slave control board sends the MAC address of the slave control BSP board to the MAC address included in the second mode control instruction through the virtual network card function in a broadcast manner; when the BSP board card receiving the broadcast is not the master control BSP board card, the broadcast is forwarded to BSP equipment connected with the BSP board card; after the master control BSP board receives the MAC addresses of all the slave control BSP boards, an IP address is generated according to the MAC addresses of all the slave control BSP boards, and the IP addresses are sent to all the slave control BSP boards in a broadcasting mode again, so that the communication connection between the master control BSP boards and the slave control BSP boards is established.
In a further embodiment, the step S3 of controlling the BSP boards to communicate according to a preset interface configuration policy to enable the BSP boards to perform an interface test with each other further includes: the main control BSP board respectively acquires a first interface transmission mode configuration parameter and a first interface transmission rate configuration parameter according to a preset interface configuration strategy; generating test data, and generating a test instruction based on the first interface transmission mode configuration parameter, the first interface transmission rate configuration parameter and the test data; addressing each slave BSP board card through a virtual network card function MAC, and sending the test instruction to each slave control board card; updating the interface configuration based on the first interface transmission mode configuration parameter and the first interface transmission rate configuration parameter under the control of the agent function; each slave BSP board card receives a test instruction and updates interface configuration based on a first interface transmission mode configuration parameter and a first interface transmission rate configuration parameter under the control of an agent function; returning test data to the main control BSP board card; the master control board card judges whether the bus interfaces of the master control BSP board card and the corresponding slave control BSP board card are normal or not according to whether the test data returned from each slave control board card can be received or not or in response to the received test data returned from each slave control board card, and whether the returned test data is consistent with the test data in the test instruction sent before or not through the proxy function comparison. It should be noted that initially, all BSP boards are configured with the same interface configuration parameters, so as to ensure that each BSP board can communicate after being started for the first time. In addition, the interface configuration strategy is used for selecting one interface transmission mode configuration parameter and one interface transmission rate configuration parameter from the plurality of interface transmission mode configuration parameters and the plurality of interface transmission rate configuration parameters to form a group for realizing the interface test of the appointed transmission rate in the appointed interface mode.
In an optional embodiment, the interface configuration policy includes acquiring and acquiring configuration parameters of transmission modes of each interface and configuration parameters of transmission rates of the interfaces in sequence in a polling manner; the method has the advantages that the comprehensive interface test can be realized, but the defects are that the test time is long and the test efficiency is not high;
in a preferred embodiment, the interface configuration policy includes setting a weight coefficient for a plurality of interface transmission mode configuration parameters; randomly acquiring at least 1 interface transmission rate configuration parameter suitable for the interface transmission mode according to the weight coefficient of the interface transmission mode configuration parameter; the larger the weight coefficient is, the more the number of interface transmission rate configuration parameters which are randomly acquired and adapt to the corresponding interface transmission mode is. The method can complete the interface test more quickly on the premise of ensuring the comprehensive test, thereby being beneficial to improving the efficiency of the interface test.
In a further embodiment, the method for testing the bus interface of the BSP board card of the present invention further includes: and responding to the master control BSP board card to finish the interface test of all slave control BSP board cards, sending a first mode control instruction to one of the slave control BSP board cards by the master control BSP board card, sending a second mode control instruction to the other slave control BSP board cards, configuring the slave control BSP board cards as the slave control BSP board cards, and finishing the interface test until all the BSP board cards in the network are sequentially configured into the master control BSP board cards and finish the test of other slave control board cards. The method has the advantages that when the master control BSP board fails to receive the test data returned from the corresponding slave control BSP board or the received returned test data is not consistent with the previously sent test data, it is indicated that the problem exists in the bus and/or the bus interface between the master control BSP board and the corresponding slave control BSP board, but the problem is difficult to accurately locate at the moment, and the problem can be accurately determined after the BSP boards are alternately used as the master control BSP boards to perform interface test. For a clearer illustration of this principle, please refer to fig. 4;
fig. 4 is a schematic diagram of a network connection relationship according to an alternative embodiment of the present invention. Wherein 10 is a master control BSP board card, and 20 to 40 are slave control BSP board cards; 50 is a connecting bus among the BSP board cards; each BSP board card comprises a chip, a storage module and a bus interface, wherein the chip is connected with the bus interface through a data bus; the storage module stores a BSP function package (the BSP function package contains a test instruction set) and an operating system.
In the process of testing an interface, setting 10 as a master control BSP board and 20 to 40 as slave control BSP boards; when the master BSP board 10 cannot receive the test data returned from the slave BSP board 20 and can normally receive the test data returned from the slave BSP board 30 and the slave BSP board 40, it indicates that a problem occurs in the data bus 50 between the master BSP board 10 and the slave BSP board 20, the bus interface 220 of the slave BSP board 20, and/or the data bus 210 of the slave BSP board 20; at this time, the problem cannot be accurately positioned; therefore, in the next stage test, the BSP board 20 is used as the master control board, and the BSP boards 10, 30 and 40 are used as the slave BSP boards, and if the master BSP board fails to receive the return data from the slave BSP board 10, the slave BSP board 30 and the slave BSP board 40, it indicates that the bus interface 220 and/or the data bus 210 of the master control board 20 is/are defective; if the master BSP board 20 can normally receive the return data from the slave BSP board 30 and the slave BSP board 40, but cannot receive the return data from the slave BSP board 10, it indicates a problem on the data bus 50 between the master BSP board 20 and the slave BSP board 10.
It should be noted that the connection relationship in fig. 4 only represents a physical connection relationship between BSP boards, and is not a network communication topology, and a network communication topology finally implemented by the present invention should be as shown in fig. 5.
Fig. 5 is a schematic view of a communication network topology of the method of the present invention. The connection between the agent function and the virtual network card function represents that the agent function and the virtual network card function have interaction; the virtual network card is used for adding an IP address and an MAC address to a sending message generated by the proxy function and sending the message to the I2C bus interface, so that the I2C bus interface packs data according to a corresponding interface transmission mode and sends the data packet at a corresponding interface transmission rate; correspondingly, the I2C bus interface of the slave BSP board unpacks the received packed data, determines the IP address and the MAC address through the virtual network card function, and sends the IP address and the MAC address to the proxy function, and the proxy function performs further operations. It should be noted that fig. 5 illustrates a communication network topology formed by only three BSP boards, but this does not limit the method of the present invention, and the method of the present invention may be applied to a variety of connection relationships with two or more BSP boards. In addition, the data bus shown in fig. 5 is an I2C data bus, which does not impose any limitation on the method of the present invention, and the data bus may also be other data buses such as GPIO.
In a further embodiment, the test instruction set further includes target setting parameters, and accordingly, the method for testing the bus interface of the BSP board further includes: in the interface testing process, target setting parameters are sent to a main control BSP board; and responding to the target setting parameters received by the main control BSP board, and sending a test instruction to a slave control BSP board appointed in the network based on the target setting parameters. The sending of the test instruction to a slave BSP board designated in a network based on the target setting parameter includes: acquiring an MAC address in a target setting parameter; and sending a test instruction to a slave BSP board designated in the network based on the MAC address.
Through the method in each embodiment, in the test of the plurality of BSP boards, the plurality of BSP boards are connected together only, the BSP boards are configured to be the master control board or the slave control board, then the plurality of BSP boards can automatically establish communication connection according to a preset test instruction set, a communication network is formed, and then communication is performed according to a preset interface configuration strategy so that the plurality of BSP boards can perform interface test with each other. The method can complete the test work of a plurality of BSP board cards in batch and quickly, and greatly improves the test efficiency of the BSP board cards.

It should be noted that the storage medium needs to be properly utilized to have an execution utility; the test instructions in the storage medium are loaded and executed in a correct utilization manner, for example, by using the BSP function package.
