Description

Technical Field

[0001] The present invention relates to the technical field of I2C link testing, and in particular to an I2C link detection method, device, equipment, and storage medium. Background Art

[0002] The I2C bus is a simple, bidirectional, two-wire synchronous serial bus developed by Philips. It requires only two wires to transmit information between connected devices. A master device initiates bus data transmission and generates a clock to open the bus for transmission. At this point, any addressed device is considered a slave. The relationship between master and slave, sender and receiver, on the bus is not constant, but depends on the direction of data transmission. To send data to a slave, the master first addresses the slave, then actively sends data to the slave, and finally terminates the data transfer. To receive data from a slave, the master first addresses the slave, then receives the data sent by the slave, and finally terminates the reception process. In this case, the master is responsible for generating the timing clock and terminating the data transfer.

[0003] I2C (Inter-Integrated Circuit), also known as the Integrated Circuit Bus in Chinese, is a serial communication bus using a multi-master-slave architecture. Designed by Philips in the early 1980s, it facilitates communication between motherboards, embedded systems, or mobile phones, and peripheral components. Due to its simplicity, it is widely used for communication between microcontrollers and sensor arrays, displays, IoT devices, EEPROMs, and more. Key features of I2C include: Only two bus lines are required; there are no strict baud rate requirements, such as with RS-232; the master device generates the bus clock; a simple master / slave relationship exists between all components, and each device connected to the bus is software-addressable via a unique address; I2C is a true multi-master bus, providing arbitration and collision detection; and since hardware design uses I2C as the physical link for inter-board monitoring, communication quality is crucial, and signal quality testing of the I2C link is required in all projects.

[0004] When developing a hardware project, all I2C signals need to be tested. There are many I2C links on the motherboard. In order to better test, the motherboard often needs to be modified, which will cause a lot of unnecessary duplication of work. Summary of the Invention

[0005] When developing a hardware project, all I2C signals need to be detected. There are many I2C links on the motherboard.

[0061] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, for ordinary technicians in this field, other drawings can be obtained based on these drawings without any creative work.

[0062] Figure 1 is a schematic flow chart of a method according to an embodiment of the present invention.

[0063] Figure 2 is a schematic block diagram of an apparatus according to an embodiment of the present invention. DETAILED DESCRIPTION

[0064] I2C is a true multi-master bus that provides arbitration and collision detection. The service uses I2C as the physical link for inter-board monitoring during hardware design. Therefore, communication quality is crucial, and signal quality testing of the I2C link is required in all projects.

[0065] When developing a hardware project, it is necessary to detect all I2C signals. There are many I2C links on the motherboard. In order to better test, the motherboard often needs to be modified, which will cause a lot of unnecessary duplication of work. In order to enable people in this technical field to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of the present invention.

[0066] like Figure 1 As shown, an embodiment of the present invention provides a method for detecting an I2C link. When designing a link, one end of all I2C links is connected to the BMC, and the other ends of all links are connected to the device and to the CPLD via a serial link. The method includes the following steps:

[0067] Step 1: Add an automatic detection web-based operation page on the BMC to display all I2C links currently managed by the BMC. Use the operation page to configure the displayed detected link channels and set up the transmission of configuration information to the BMC.

[0068] Step 2: After receiving the configuration information, the BMC sends it to the CPLD to start the loopback of the corresponding link channel and receives a feedback response from the CPLD after startup.

[0069] Step 3: After receiving the response, the BMC sends I2C data to the device connected to the link channel. If the BMC receives the data returned by the CPLD within the set time, the link channel test passes.

[0070] The server's I2C link is connected to the BMC at one end and to sensors, VRs, and other devices at the other end. An automatic detection page is added to the BMC. This web-based operation page allows configuration of the detected signals. Upon entering the page, all current I2C links are automatically detected, and you can select all, one, or several I2C links for detection.

[0071] The BMC displays the managed I2C links. The page display effect is shown in Table 1:

[0072] Table 1

[0073]

[0074] When performing a test, you only need to configure the links that need to be tested. This can be configured for full or partial testing. When designing the links, one end of each I2C link is connected to the BMC, and the other end is connected to the device and the CPLD via a serial link.

[0075] At the same time, there is a dedicated link I2C5 between the BMC and CPLD for direct communication between the BMC and CPLD. After receiving the configuration information of the link to be tested, the BMC sends instructions to the CPLD. The CPLD will connect the link to be tested with the device to open the link channel from the BMC to the device to achieve the loopback effect.

[0076] For example, to test the connectivity of Channel 1 on I2C1 (9548), enable Channel 1 testing on the BMC web page. Data from the BMC page is sent to the BMC. After receiving the message, the BMC sends the data to the CPLD via I2C5. The CPLD initiates a loopback on Channel 1 and sends a response back to the BMC. After receiving the response, the BMC starts a data simulation program, sending I2C data to Channel 1 at a fixed I2C frequency (100 MHz or 400 MHz). The CPLD receives the data returned by the device connected to Channel 1 and returns it to the BMC, achieving a data loopback and enabling automatic testing.

[0077] An embodiment of the present invention provides an I2C link detection method. During link design, one end of all I2C links is connected to a BMC, and the other ends of all links are connected to external devices and to a CPLD via a serial link. The method includes the following steps:

[0078] Step 1: Add an automatic detection web-based operation page on the BMC to display all I2C links currently managed by the BMC. Use the operation page to configure the displayed detected link channels and set up the transmission of configuration information to the BMC.

[0079] This step specifically includes: generating a custom form for displaying the I2C link managed by the BMC through the BMC front-end web interface; setting up a form page to collect configuration information for form items on the form page; and converting the collected configuration information and submitting it to the BMC.

[0080] Here, the steps of generating a custom form for displaying the I2C link managed by the BMC through the BMC front-end web interface include: creating a front-end form configuration interface, selecting corresponding form elements through the front-end interface, and generating a custom form; in the web interface, by calling the BMC back-end interface to return the I2C link information managed by the BMC in the front-end custom form, obtaining the I2C link information managed by the BMC, rendering the corresponding form, and displaying it on the web interface.

[0081] Step 2: After receiving the configuration information, the BMC sends it to the CPLD to start the loopback of the corresponding link channel and receives a feedback response from the CPLD after startup.

[0082] Step 3: After receiving the response, the BMC sends I2C data to the device connected to the link channel. If the BMC receives the data returned by the CPLD within the set time, the link channel test passes;

[0083] Step 4: After the test is completed, a test report is automatically generated.

[0084] It should be noted that, in this embodiment, after receiving the configuration information, the BMC sends the configuration information to the CPLD for initiating a loopback of the corresponding link channel, and receives a feedback response from the CPLD after the CPLD is activated. The steps include:

[0085] Step 21: After receiving the configuration information, the BMC sends the configuration information to the CPLD;

[0086] Step 22: After receiving the configuration information, the CPLD parses the received information to obtain the I2C link channel information;

[0087] Step 23: Select the device of the corresponding link based on the parsed I2C link channel information and connect it to the BMC to start the loopback of the link channel;

[0088] Step 24: After the startup is complete, the CPLD feeds back a response message to the BMC.

[0089] Accordingly, after receiving the response, the BMC sends the I2C data to the device connected to the link channel, including the following steps:

[0090] Step 31: After receiving the response, the BMC starts the data simulation program and sends I2C data to the device connected to the link channel according to the fixed frequency of I2C.

[0091] Step 32: The device forwards the received data to the CPLD;

[0092] Step 33: After receiving the data, the CPLD returns the data to the BMC.

[0093] The method provided in this application provides a web-based operation page for configuring the link being tested. Configuration on this page allows for either full or partial testing. By sending configuration information to the CPLD, the CPLD initiates a loopback link, connecting two I2C links. During testing, different frequencies are automatically sent to test the I2C link and automatically generate a report. This improves product R&D efficiency and reduces R&D costs.

[0094] like Figure 2 As shown, an embodiment of the present invention further provides an I2C link detection device. When designing a link, one end of all I2C links is connected to the BMC, and the other ends of all links are respectively connected to the outside of the device and also connected to the CPLD through a serial link. The device includes a display setting module, a loopback start setting module, and a detection module.

[0095] The display settings module is used to add an automatic detection web-based operation page on the BMC to display all I2C links currently managed by the BMC. The operation page allows you to configure the displayed detected link channels and set the configuration information to be transmitted to the BMC;

[0096] The loopback startup setting module is used to send the configuration information to the CPLD after the BMC receives it to start the loopback of the corresponding link channel, and receive the feedback response after the CPLD starts;

[0097] The detection module is used to send I2C data to the device connected to the link channel after the BMC receives the response. If the BMC receives the data returned by the CPLD within a set time, the link channel test passes.

[0098] A web-based operation page is provided for configuring the link being tested. This page allows for full or partial testing. By sending configuration information to the CPLD, the CPLD initiates a loopback link, connecting two I2C links. During testing, different frequencies are automatically sent to test the I2C link.
