[0034] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solution of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0035] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0036] With the continuous development of the Data Processing Unit (DPU), DPU boards are gradually moving towards mass production. The physical address (Mac) / serial number (SN) is the main feature for identifying different DPU boards, and it needs to be written into the Flash chip of the board when the board welding is completed, and the content posted on the label is consistent with the written information.

[0037] In the related art, usually before the board welding, the Mac / SN is written into the Flash chip of the board through a programmer. The main steps of the existing programmer for burning include: selecting the chip model, loading the data file to be burned, setting the operation options, placing the chip, and performing the burning operation.

[0038] However, in the related art, there are the following disadvantages: 1) The chip model to be burned needs to be within the support range of the programmer, and those not within cannot be burned; 2) The burning time using the programmer is relatively long, and it cannot meet the measurement requirements of mass production; 3) There is a risk of electrostatic damage during the manual burning process of the chip; 4) After the burning is completed, the board needs to be inserted into the host to read out the written information to verify whether the writing is correct, check whether there is any missing writing, and then paste the label, and the process is relatively cumbersome.

[0039] In view of this problem, an embodiment of the present disclosure provides a method for writing an identification code of a DPU board. The following introduces this method in combination with specific embodiments.

[0040] Figure 1 FIG. is a flowchart of a method for writing an identification code of a DPU board provided by an embodiment of the present disclosure. The execution subject of this method is an electronic device. The electronic device can be a terminal device, such as a test host, and the test host can specifically be a portable mobile device such as a tablet computer or a notebook computer; it can also be a fixed device such as a personal computer, a smart home appliance, or a server. Among them, the server can be a single server, can be a server cluster, and the server cluster can be a distributed cluster or a centralized cluster. This method can be applied to the scenario of writing an identification code for a DPU board. It can be understood that the method for writing an identification code of a DPU board provided by an embodiment of the present disclosure can also be applied in other scenarios.

[0041] A DPU is a processor specifically used for data processing, focusing on data processing to achieve more efficient data processing and computing. In modern computer systems, a data processing unit (DPU) card is a key component that is responsible for processing a large amount of data and performing fast calculations.

[0042] The following introduces Figure 1 the method for writing an identification code of the DPU board shown below. First, install a serial port driver program and a host computer program on the terminal device, and communicate and connect the target DPU board with the terminal device through the target serial port. The specific steps included in this method are as follows:

[0043] S101. Identify the port number of the target serial port through the serial port driver program.

[0044] In this step, a serial port driver program and a host computer program are installed on the terminal device. The target DPU board is communicatively connected to the terminal device through the target serial port. As Figure 4 shown, connect the target DPU board and the terminal device through a serial cable, such as a universal asynchronous receiver / transmitter (Uart) serial cable. Further, the terminal device can identify the port number of the target serial port through the serial port driver program. The target DPU board is the DPU board for which the identification code is to be written.

[0045] S102. In response to the user starting the host computer program, obtain the identification code information to be written for the target DPU board, and fill the identification code information into the read / write file of the target DPU board.

[0046] In this step, the user will start the host computer program. In response to the user starting the host computer program, the terminal device will obtain the identification code information to be written to the target DPU board, and fill the identification code information into the read-write file of the target DPU board. Optionally, the identification code information may include physical address Mac information and / or serial number SN information. Specifically, when the user opens the host computer program, the identification code information to be written to the target DPU board can be obtained, and then the host computer program fills the identification code information into the read-write file of the target DPU board. The read-write file can be the nic_info.cfg file, which is the location for reading and writing the content of each board.

[0047] S103. In response to the user's operation of clicking the start button in the host computer program, perform a write operation based on a preset write instruction, and write the identification code information to the target chip of the target DPU board through the target serial port.

[0048] In this step, the user will click the start button in the host computer program. In response to the user's operation of clicking the start button in the host computer program, the terminal device will perform an identification code writing operation based on a preset write instruction, and write the identification code information to the target chip of the target DPU board through the target serial port. The target chip can be a Flash chip, which is not limited. Optionally, the preset write instruction can be expressed as: yscom-p COM14-w-f nic_info.cfg.

[0049] Among them, -p or --port is used to specify the port number of the serial port used by the host computer. Taking the port number COM14 as an example, it is not limited; -w indicates that network card information is to be written to the board; -f is used to specify the content of the written information.

[0050] In some embodiments, the target DPU board is inserted into a board base, and the board base is used to supply power to the target DPU board.

[0051] As Figure 4 shown, the target DPU board is inserted into the board base, and the board base will supply 12V power to the board. The board base can be a PCIE base, which is not limited.

[0052] In some embodiments, the board base is fixed on a preset template base, the preset template base is used to supply power to the board base, and the upper part of the target DPU board is fixed by a preset template cover.

[0053] As Figure 4As shown, the board card base is fixed on the preset template base. The preset template base is used to supply power to the board card base (12V - 10A). The number of inserted board cards can be adjusted according to actual needs. There is a QR code label pasted on the board card, and a scanning position for the board card QR code label is reserved. There is a preset template cover above the target DPU board card. The preset template cover is used to fix the board card and can check whether the board card is inserted in place.

[0054] S104. When receiving the indication information that the write operation is completed, perform a read operation based on the preset read instruction, and read the identification code information from the target chip of the target DPU board card through the target serial port.

[0055] In this step, if the write operation is completed, a prompt for the completion of the write operation will be given. When the terminal device receives the indication information that the write operation is completed, it will perform a read operation based on the preset read instruction, and read the identification code information from the target chip of the target DPU board card through the target serial port. Optionally, the preset read instruction can be expressed as: yscom-p COM14-r-f nic_info.cfg.

[0056] Among them, -p or --port is used to specify the port number of the serial port used by the host computer. Taking the port number COM14 as an example, it is not limited; -r indicates that the network card information is to be read from the board card; -f is used to indicate that the information read from the board card is to be jumped (dumped) to a specified file for comparison.

[0057] S105. If the read identification code information is the same as the identification code information in the read / write file of the target DPU board card, it is determined that the writing of the identification code information of the target DPU board card is successful, and the next writing step for the DPU board card identification code is executed.

[0058] The purpose of this step is to compare the information integrity and consistency. If the read identification code information from the target DPU board card is the same as the identification code information in the read / write file of the target DPU board card, it indicates that the writing is successful, and then the next writing step for the DPU board card identification code is executed.

[0059] In the embodiments of the present disclosure, the port number of the target serial port is identified through a serial port driver. In response to the user starting the host computer program, the identification code information to be written to the target DPU board is obtained, and the identification code information is filled into the read-write file of the target DPU board. In response to the user clicking the start button in the host computer program, a write operation is performed based on a preset write instruction, and the identification code information is written to the target chip of the target DPU board through the target serial port. When an indication information indicating that the write operation is completed is received, a read operation is performed based on a preset read instruction, and the identification code information is read from the target chip of the target DPU board through the target serial port. If the read identification code information is the same as the identification code information in the read-write file of the target DPU board, it is determined that the writing of the identification code information of the target DPU board is successful, and the writing step of the identification code of the next DPU board is executed. Compared with the prior art, in the embodiments of the present disclosure, writing through the serial port method is not limited by the chip model, can improve the burning efficiency, avoid the risk of electrostatic damage caused by directly contacting the chip, simplify the burning process, and multiple boards can be inserted simultaneously. After a batch of writing is completed, the next batch is replaced, avoiding frequent plugging and unplugging of the boards during the writing process.

[0063] S202. In response to the user starting the host computer program, scan and identify the two-dimensional code label on the surface of the target DPU board through a scanning device to obtain the identification code information to be written to the target DPU board.

[0064] In this step, the user starts the host computer program, and the terminal device, in response to the user starting the host computer program, scans and identifies the two-dimensional code label on the surface of the target DPU board through a scanning device to obtain the identification code information to be written to the target DPU board. Optionally, the scanning device can be a barcode scanner, which is not limited.

[0065] S203. Fill the identification code information into the read-write file of the target DPU board.

[0066] Further, after obtaining the identification code information to be written to the target DPU board, the identification code information is filled into the read-write file of the target DPU board. The read-write file can be the nic_info.cfg file, which is used as the content position for reading and writing each board.

[0067] S204. Determine the target serial port based on the port number of the target serial port in the preset write instruction.

If the read identification code information is the same as the identification code information in the read / write file of the target DPU board, it is determined that the writing of the identification code information of the target DPU board is successful, and the writing step of the next DPU board identification code is executed.

[0076] Specifically, the implementation processes and principles of S208 and S105 are the same, and will not be elaborated here.

[0077] In the embodiments of the present disclosure, the port number of the target serial port is identified through a serial port driver. In response to the user starting the host computer program, a scanning device is used to scan and identify the QR code label on the surface of the target DPU board to obtain the identification code information to be written to the target DPU board, and the identification code information is filled into the read-write file of the target DPU board. Further, based on the port number of the target serial port in the preset write instruction, the target serial port is determined, and the identification code information to be written is obtained from the read-write file of the target DPU board through the target serial port, and the identification code information is written to the target chip of the target DPU board through the target serial port. When the indication information indicating that the write operation is completed is received, a read operation is performed based on the preset read instruction, and the identification code information is read from the target chip of the target DPU board through the target serial port. Furthermore, if the read identification code information is the same as the identification code information in the read-write file of the target DPU board, it is determined that the writing of the identification code information of the target DPU board is successful, and the writing step of the identification code of the next DPU board is executed.
