In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a server serial port debugging method according to an embodiment of the present invention.
Referring to fig. 1, in the embodiment of the present invention, a server serial port debugging method includes:
s101: and calling a plurality of receiving serial port interfaces through the CPLD to acquire debugging data corresponding to a plurality of chips.
In the embodiment of the present invention, a CPLD (complex programmable logic device) has a plurality of receiving serial interfaces, the CPLD links a plurality of chips through the plurality of receiving serial interfaces, the chips may be a BMC, a memory controller, a PCIe controller, and the like, and specific types and specific functions of the chips are not specifically limited in the embodiment of the present invention, depending on the specific circumstances. It should be noted that the receiving serial port interfaces are generally in one-to-one correspondence with the chips, so that the CPLD can query the debug data of the chips through the receiving serial port interfaces, and correspondingly, in this step, the CPLD can call the multiple receiving serial port interfaces to obtain the debug data corresponding to the multiple chips. For the details of the debugging data, reference may be made to the prior art, and further description is not repeated herein.
S102: and adding a start keyword corresponding to the receiving serial port interface at least at the head part of the debugging data and adding an end keyword corresponding to the receiving serial port interface at least at the tail part of the debugging data through the CPLD.
After the CPLD obtains the respective debug data of the plurality of chips through the plurality of receiving serial interfaces, in this step, a start keyword corresponding to the receiving serial interface is added to the head of the debug data, and an end keyword corresponding to the receiving serial interface is added to the tail of the debug data. That is, if a certain piece of debug data is specifically data received through the first receiving serial port interface, it indicates that the debug data is specifically debug data of a chip connected to the first receiving serial port interface. Correspondingly, in this step, the beginning keyword and the ending keyword corresponding to the first receiving serial port interface are added to the beginning and the end of the debugging data respectively, so that the upper computer in the subsequent step can identify that the debugging data is the debugging data of the chip specifically according to the beginning keyword and the ending keyword.
For example, for the first receiving serial interface, the corresponding start key may be/1, and the end key may be set to 1 ×/; for the second receiving serial port interface, the corresponding start key word may be/2, and the end key word may be set to 2 ×/; and so on. Of course, the specific contents of the start keyword and the end keyword may be set according to the actual situation, and are not limited specifically herein.
S103; calling a transmitting serial port interface through the CPLD to transmit the debugging data added with the start keywords and the end keywords to the upper computer, and distinguishing and displaying the debugging data according to the start keywords and the end keywords through the upper computer.
In this step, the CPLD specifically sends the debug data added with the start keyword and the end keyword to the upper computer through a sending serial port interface, and at this time, the upper computer can distinguish the specifically corresponding receiving serial port interface of each piece of debug data according to the start keyword and the end keyword, and the specifically corresponding chip, that is, can distinguish the pieces of debug data according to the start keyword and the end keyword, and display the debug data distinguished by each piece of debug data respectively. Specifically, when the upper computer is provided with enough displays, debugging data received by a receiving serial port interface can be displayed in each display; when the number of the displays is insufficient, the displays may be split to display all the debugging data, or only part of the debugging data may be displayed in the displays, which is not specifically limited in the embodiment of the present invention. It should be noted that, in this step, the upper computer usually only displays the content between the start keyword and the end keyword, and usually does not display the start keyword and the end keyword themselves.
Preferably, in the embodiment of the present invention, in order to ensure that the upper computer can display the debug data of each chip in time, the transmission rate of the sending serial port interface generally needs to be not less than the sum of the transmission rates of all the receiving serial port interfaces, so as to ensure that the debug data received by the CPLD can be transmitted to the upper computer in time.
Specifically, in the embodiment of the present invention, the receiving serial interface is usually a UART serial interface, and a UART (Universal Asynchronous Receiver/Transmitter) serial interface is used to effectively improve the receiving efficiency of the CPLD on the debugging data. Correspondingly, in the embodiment of the present invention, the transmitting serial port interface is generally connected to the upper computer through a cable. The CPLD and the upper computer are connected through cables, so that the communication stability between the CPLD and the upper computer can be obviously improved, and the upper computer can stably receive debugging data of each chip.
The server serial port debugging method provided by the embodiment of the invention can firstly acquire debugging data corresponding to a plurality of chips through a plurality of receiving serial port interfaces by a CPLD; then, adding a start keyword corresponding to the receiving serial port interface at least at the head of the debugging data and adding an end keyword corresponding to the receiving serial port interface at least at the tail of the debugging data through the CPLD; and finally calling a transmitting serial port interface through the CPLD to transmit the debugging data added with the start keywords and the end keywords to the upper computer, and distinguishing and displaying the debugging data according to the start keywords and the end keywords through the upper computer. Debugging data corresponding to a plurality of chips can be simultaneously transmitted to the upper computer through the CPLD only through one transmitting serial port interface, so that the upper computer only needs to be connected with the CPLD by leading out a line, and the using quantity of interfaces in the upper computer is greatly reduced; the debugging data can be distinguished and displayed through the start keyword and the end keyword, and the debugging data of a plurality of chips can be displayed simultaneously.
The details of the server serial port debugging method provided by the present invention will be described in detail in the following embodiments of the present invention.
Referring to fig. 2, fig. 2 is a flowchart of a specific server serial port debugging method according to an embodiment of the present invention.
Referring to fig. 2, in the embodiment of the present invention, a server serial port debugging method includes:
s201: and calling a plurality of receiving serial port interfaces through the CPLD to acquire debugging data corresponding to a plurality of chips.
S202: and adding a start keyword corresponding to the receiving serial port interface at least at the head part of the debugging data and adding an end keyword corresponding to the receiving serial port interface at least at the tail part of the debugging data through the CPLD.
S201 to S202 are substantially the same as S101 to S102 in the above embodiment of the invention, and for details, reference is made to the above embodiment of the invention, which is not repeated herein.
S203: and identifying the characters to be identified which are the same as the starting keyword and the ending keyword in the debugging data through the CPLD.
In this step, the debugging data is traversed through the CPLD to identify the character to be identified in the debugging data that is the same as the preset start keyword and end keyword. Because the debugging data of different chips are distinguished in the form of adding the keywords in the debugging data, the characters to be recognized which are the same as the preset starting keywords and ending keywords may exist in the debugging data, and the characters to be recognized interfere with the recognition of the upper computer, so that the upper computer cannot accurately recognize and display the complete debugging data. Correspondingly, in this step, the characters to be recognized, which are the same as the start keyword and the end keyword in the debug data, need to be recognized through the CPLD first, so that the characters to be recognized are processed in the subsequent steps.
S204: and breaking the character to be recognized, adding an ending keyword at the tail of the previous debugging data, and adding a starting keyword at the beginning of the next debugging data.
In this step, the character to be recognized is usually interrupted by the CPLD, so that the debugging data is divided into two pieces of debugging data at the character to be recognized. Taking "1 x/" as an example, if the debugging data itself has a character to be recognized 1 x/, and the character to be recognized is the same as the ending keyword of the first receiving serial port interface, the debugging data needs to be interrupted in the middle of the character to be recognized in this step, at this time, the end of the former piece of debugging data may be 1 x, and the beginning of the latter piece of debugging data may be/; if the debugging data are received by the CPLD through the second receiving serial port, 2 is added at the tail of the previous section of debugging data and 2 is added at the head of the next section of debugging data in the step, the modification of the debugging data is completed, so that the upper computer can completely identify each section of debugging data, and the upper computer only needs to merge and display each section of debugging data. Of course, the specific form of the character to be recognized in this step is not particularly limited, as the case may be.
It should be noted that, in general, there is no sequence between the above S203 to S204 and the above S202, S203 to S204 may be executed before S202, S203 to S204 may be executed after S202, or S203 to S204 may be executed in parallel with S202, which is not limited in this embodiment of the present invention.
S205; calling a transmitting serial port interface through the CPLD to transmit the debugging data added with the start keywords and the end keywords to the upper computer, and distinguishing and displaying the debugging data according to the start keywords and the end keywords through the upper computer.
This step is substantially the same as S103 in the above embodiment of the present invention, and details have been described in the above embodiment of the present invention, and are not described herein again.
According to the server serial port debugging method provided by the embodiment of the invention, CPLD identifies and breaks the character to be identified, and adds the corresponding ending keyword and the starting keyword at the breaking position, so that the error of upper computer identification caused by the existence of the same character as the starting keyword and the ending keyword in debugging data can be effectively avoided.
In the following, the server serial port debugging system provided by the embodiment of the present invention is introduced, and the server serial port debugging system described below and the server serial port debugging method described above may be referred to in a corresponding manner.
