In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments. It should be understood that the embodiments and specific features in the embodiments are detailed description of the technical solutions of the embodiments and are not limited to the technical solutions of the embodiments, and the technical features in the embodiments and specific features in the embodiments can be combined with each other without conflict.
First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
The embodiment provides a serial port information positioning method, which is applied to a serial port information positioning system, wherein the serial port information positioning system is connected with a target system, as shown in fig. 1, the method is a flow chart of the serial port information positioning method provided by the embodiment of the specification, and the method comprises the following steps:
step S101: acquiring serial port information of the target system;
step S102: acquiring a trigger signal for the target system;
step S103: and associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal.
In the embodiment of the present specification, the target system may be a server system or an electronic device terminal system, and the target system may output serial port information in real time during an operation process. The serial port information positioning system is connected with the target system and used for receiving the serial port information output by the target system. The serial port information positioning method provided by the embodiment of the specification can be applied to various scenes, such as the analysis of the serial port information of a target system in the scenes of starting, running, shutdown and the like through a serial port information positioning system. For convenience of description, in the embodiments of the present specification, a target system is taken as a server system, and a serial port information positioning system analyzes serial port information in a boot process of the server system.
As shown in fig. 2, a schematic diagram of a serial port information positioning system provided in an embodiment of this specification is shown, where the serial port information positioning system includes: PCH (Platform Controller Hub), BMC (Baseboard Management Controller), MCU (Microcontroller Unit), and oscilloscope.
The PHC is configured to receive Serial port information sent by the target system, and send the Serial port information to the BMC through an LPC (Low pin Bus) and an Enhanced Serial Peripheral Interface (eSPI).
The BMC is in communication connection with the MCU, and specifically, the BMC may send the received serial port information to the MCU through a UART (Universal Asynchronous Receiver/Transmitter).
The oscilloscope is connected with the MCU through the USB and is used for monitoring whether the target system generates a trigger signal in real time and sending the detected trigger signal to the MCU. The MCU is used for carrying out correlation processing on the received trigger signal and the serial port signal.
Of course, the serial port positioning system may also be adjusted according to actual needs, such as adding or deleting functional modules, adjusting data transmission modes, and the like, which is not specifically limited herein. For example: an UARTTORS232 chip can be added behind the MCU for converting serial port information into RS232 level and the like.
In step S101, the serial port information may be BIOS (Basic Input Output System) information Output by the target System in the starting process. Specifically, the target system is a server system, and in the process of starting the server system, serial port information is output in real time, and the serial port information from the server system can be acquired in real time through a PCH (Platform Controller Hub).
In step S102, the target system may send some trigger signals at some stages during the processes of starting or closing, for example, when the system is started, the trigger signals may be generated when the driver is started; some signals are also triggered abnormally when the system is abnormal. There are many types of trigger signals, such as Platform reset signal, I3C signal, CATER signal, etc. In this specification, the target system may be monitored in real time by an oscilloscope, and when a trigger signal is monitored, the trigger signal is acquired in real time.
As an optional embodiment, the obtaining of the trigger signal for the target system specifically includes: detecting the waveform change of the target system electric signal; and acquiring the trigger signal corresponding to the waveform change.
In this specification, the method for acquiring the trigger signal specifically includes: and monitoring the waveform change condition of the electric signal of the target system in real time through an oscilloscope. The input end of the oscilloscope is connected with the target system, and the output end of the oscilloscope is connected with the serial port information positioning system through the USB interface. When the waveform of the electric signal is suddenly changed, the oscilloscope acquires the waveform and analyzes and matches a corresponding trigger signal. It should be noted that, different trigger signals may have different corresponding waveform changes, for example, when the target system is stable, the waveform of the output electrical signal is a sine wave, and when the Platform Reset trigger signal occurs, the waveform of the output electrical signal of the target system changes to a falling edge waveform, so when the above waveform change is detected, it can be determined that the corresponding trigger signal is the Platform Reset trigger signal.
Further, step S103 is performed: and associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal.
The trigger time may be the time of the target system when the serial port information positioning system receives the trigger signal, or the current area time when the serial port information positioning system receives the trigger signal. When the target system sends out a trigger signal, recording the time for acquiring the trigger signal, and associating the trigger signal with the serial port information received in real time when the trigger signal is acquired.
The association method may be to perform data binding on the trigger signal and the serial port information according to the trigger time, label the serial port information by using the trigger time as a time stamp, insert the trigger time into the serial port information, and the like. Taking the triggering time as the current area time when the serial port information positioning system receives the triggering signal, and the association mode is to perform data binding on the triggering signal and the serial port information according to the triggering time as an example: the target system sends out a trigger signal at 2020.12.12.22.00, records the time 2020.12.12.22.00, and binds the data of the trigger signal to the serial port information obtained at 2020.12.12.22.00.
As an optional embodiment, before associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal, the method further includes: determining the working mode of the serial port information positioning system; and when the working mode is a debugging mode, executing the step of associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal.
Specifically, the serial port information positioning system can have a plurality of working modes, including a debugging mode, a bypass mode and the like, wherein in the bypass mode, serial port information acquired by the serial port information positioning system can be directly transmitted to a transmitting end of the serial port information positioning system, and the association processing of the serial port information and trigger information is not executed, so that the working efficiency of the serial port information positioning system is improved; and when the working mode is the debugging mode, the serial port information positioning system executes the step of associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal.
As an optional embodiment, the serial port information positioning system includes a jumper cap and three jumpers, where the three jumpers correspond to the first jumper, the second jumper, and the third jumper, respectively, and the determining the operating mode of the serial port information positioning system includes: and determining the working mode according to the connection mode of the jumper cap and the jumper, wherein when the jumper cap is connected with the second jumper pin and the third jumper pin of the jumper, the working mode is determined to be the debugging mode.
The operation mode can be switched in various ways, for example, by setting a jumper cap and a jumper connection, by setting a switch, and the like. The working mode of the system is determined by changing the jumper cap and the jumper connection mode. Three jumper wires are arranged on the serial port information positioning system and respectively correspond to a first jumper pin, a second jumper pin and a third jumper pin, namely, the serial port information positioning system is in a bypass mode when a jumper wire cap is jumped to 1 pin or 2 pins, namely, the serial port information positioning system does not perform any processing and directly outputs the serial port information after receiving the serial port information, so that the time delay of a serial port of the system is reduced.
When the jumper cap is detected to jump on the 2pin or 3pin jumper, the serial port information positioning system is in a debugging mode, namely the serial port information positioning system executes the triggering time corresponding to the triggering signal, and the triggering signal is associated with the serial port information.
As an optional embodiment, the associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal includes: and determining a target position corresponding to the trigger time in the serial port information, and inserting a trigger mark for representing that the trigger signal is triggered at the target position.
The trigger time may be the time of the target system when the serial port information positioning system receives the trigger signal, or the current area time when the serial port information positioning system receives the trigger signal. When a target system sends a trigger signal, recording the trigger time, then determining the serial port data received under the trigger time based on the receiving time of the serial port information, taking the position of the serial port data as a target position, and inserting a trigger mark triggered by the trigger signal into the target position. The trigger flag may be a type of trigger signal, english abbreviation of trigger signal, or the like. Taking the trigger time as the time of the target system running when the serial port information positioning system receives the trigger signal, and the trigger mark is the trigger signal, which is abbreviated in English, as an example, when the target system runs to 15min22s30ms, a Platform Reset trigger signal is sent out, the serial port information positioning system obtains the trigger signal and records the trigger time, then finds the serial port information position obtained when the target system runs to 15min22s30ms in the serial port information, and inserts information "Reset" in the position to represent that the target system sends the Platform Reset trigger signal at the position.
As an optional embodiment, after the associating the trigger signal with the serial port information based on the trigger time corresponding to the trigger signal, the method further includes: when serial port information is positioned, determining target data corresponding to the target position in the serial port information based on the trigger mark; determining an operational state of the target system based on the target data.
Specifically, when a tester debugs a target system, the debugging equipment is accessed into the serial port information positioning system to start reading serial port information, a trigger mark is determined in the read serial port information, and the position of the trigger mark is the target position. And obtaining serial port information before and after the position of the trigger mark according to the trigger mark, namely the target data. And then determining the running state of the target system when the trigger signal is triggered by analyzing the content of the target data. For example: when the serial port information positioning system receives serial port information in a starting process of a target system at one time, due to the fact that a Platform Reset signal is triggered abnormally when the target system is started abnormally, the serial port information positioning system monitors and obtains the Platform Reset signal, records trigger time corresponding to the acquired signal, determines serial port data received under the trigger time based on the receiving time of the serial port information, takes the position of the serial port data as a target position, and inserts a trigger mark 'Reset' triggered by the Platform Reset signal into the target position. When a tester debugs, the trigger mark 'Reset' is found through the debugging equipment, the trigger of the Platform Reset signal can be known, then serial port data before and after the trigger mark 'Reset' is analyzed, and the running state of the target system is known that the BIOS is checking the DIMM when the Platform Reset signal is triggered. The tester can then look to see if the code has a problem with the configuration of the DIMM based on this information.

an obtaining module 301, configured to obtain serial port information of a target system;

In order to better understand the solution of the embodiment of the present invention, as shown in fig. 4, this specification provides a schematic diagram of a preferred apparatus of a serial port information positioning system to further explain the solution.
As shown in fig. 5, Serial port information sent by the target system is received by the PCH, and the PCH receives the Serial port information and then sends the Serial port information to the BMC (Baseboard Management Controller) through LPC (Low pin count Bus) and eSPI (Enhanced Serial Peripheral Interface). The BMC then sends serial port information to an MCU (Microcontroller Unit) through a UART (Universal Asynchronous Receiver/Transmitter). Meanwhile, the oscilloscope connected with the MCU through the USB monitors whether the target system is triggered by a trigger signal in real time through the connection with the target system.
After the MCU acquires the serial port information, a UARTTORS232 chip can be arranged for converting the received serial port information of the MCU into an RS232 level from UART data. In addition, a DB-9/RJ45 interface may be provided to receive the RS232 level from the UARTTORS232 chip and send it to an external receiver.
When the jumper cap on the MCU jumps to the 1 pin and 2pin jumper, the serial port information positioning system is in a bypass mode, the MCU does not perform any processing on serial port information sent by the BMC, and the serial port information is directly sent to the UARTToRS232 chip through the UART, and the UARTToRS232 chip converts the serial port information into RS232 level and sends the RS232 level to the DB-9/RJ45 interface to send the serial port information.
When the jumper cap on the MCU jumps to the 2pin and 3pin jumper, the serial port information positioning system is in a debugging mode. At the moment, the MCU receives and analyzes the serial port information, and then repackages the serial port information into UART data to be output to the UARTTORS232 chip. The data of the USB interface can be monitored in real time in the process of packaging the serial port information by the MCU, when the USB interface receives a trigger signal monitored by the oscilloscope, the MCU inserts a trigger mark into the serial port information received when receiving the trigger signal, and then the serial port information and the trigger mark are packaged together and output to the UARTTORS232 chip. Converted to RS232 level. When the tester obtains the serial port information at the accessed debugging equipment, the tester searches the position of the serial port information where the trigger mark is located, and then the specific process and state of the system operation at the moment can be positioned.
