Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present specification.
In the network device, as shown in fig. 1, a main control board and a plurality of single boards may be included, and the main control board and the single boards are connected through a bus, for example, through a PCIE (Peripheral Component Interconnect Express). The main control board and the single board have similar structures and comprise a processor, a memory and a storage. The memory is generally a Flash memory with a small capacity for realizing the startup of the board, for example, a NOR (nand gate) Flash, an SPI (Serial Peripheral Interface) Flash, and the like, because the space of the board is limited. Since the space of the main control board is large, two memories may be respectively provided, one is a flash Memory with a small capacity, similar to the single board, for implementing the start of the main control board, and the other is a Memory with a large capacity, such as a hard disk, an SD (Secure Digital Memory) card, and the like, for storing the boot file used by the upgraded single board.
For a board, a first boot file may be stored in the memory, and the first boot file, as shown in fig. 2, includes a basic reset configuration word, a boot program, and at least two segments of classification reset configuration words. The basic reset configuration word is set at the head of the first boot file, each segment of the classified reset configuration word corresponds to a type of single board, and the classified reset configuration word can be positioned through a field in the boot program and is not limited to setting the classified reset configuration word at a specific position in the first boot file.
It should be noted that, the reset configuration word is used to configure the board, and the functions that can be implemented include, but are not limited to, early driving, obtaining board identifiers in registers (for example, complex Programmable Logic Devices (CPLDs)), board communication, and the like, and these configurations are common to various types of boards, and therefore, the common reset configuration word located at the head in the first boot file may be referred to as a basic reset configuration word. In addition, in the reset configuration word, it is also possible to implement selection of a network port SERDES (SERializer, DESerializer), selection of a rate mode, a multiplexing mode of a pin, and the like, and these matches may be different for different single boards, so that it is necessary to configure one type of single board to use the corresponding reset configuration word. Here, the reset configuration word may be referred to as a sort reset configuration word for different types of boards.
And, the space occupied by the basic reset configuration word and each classification reset configuration word is the same, for example, both can be set to 4 kbytes.
Based on the foregoing single board structure, the present application provides a single board starting method, as shown in fig. 3, including:
s100, acquiring a first boot file pre-stored in a memory.
The first boot file is pre-stored in a memory of the board, and the processor can acquire data from the memory after being powered on to acquire the first boot file. The obtaining process may be understood as reading the first boot file into the memory of the board. For example, in the network device shown in fig. 1, two boards, that is, board 1 and board 2, may be included, and correspondingly, in the first boot file shown in fig. 2, the categorized reset configuration word 1 corresponding to board 1 and the categorized reset configuration word 2 corresponding to board 2 may be included.
And S102, initializing the board according to the basic reset configuration word and the bootstrap program.
And acquiring a basic reset configuration word from the head of the first boot file, and initializing the board according to the basic reset configuration word and the boot program, so that the processor can acquire the board identifier. It should be noted that the initialization process is not limited to the above-described process, and includes other operations, which are not described herein since the other operations are similar to the existing initialization process.
S104, in the process of initialization, acquiring the single board identification of the board, and determining the classified reset configuration word corresponding to the single board identification in the first boot file.
During initialization, resources such as registers may be enabled, thereby enabling the processor to read data stored in the registers. For example, a board identifier configured for each board.
The corresponding relation between the single board identification and the classification resetting configuration words in the first guide file can be stored on the single board. In the first boot file, a number may be set for different reset configuration words, for example, the number of the basic reset configuration word is 0, the number of the class reset configuration word configuring the board 1 is 1, and the number of the class reset configuration word configuring the board 2 is 2.
Based on the board identifier of the board, the classification resetting configuration word corresponding to the board identifier may be found in the first guidance file, for example, the classification resetting configuration word 1 corresponding to the board 1 may be found.
And S106, replacing the basic reset configuration word in the first boot file in the memory by the determined classification reset configuration word to form a second boot file.
And reading out the classified reset configuration word after determining the classified reset configuration word corresponding to the single board identifier. And comparing the read classification reset configuration word with the basic reset configuration word of the head part of the first guide file, and if the classification reset configuration word is not consistent with the basic reset configuration word, representing that the classification reset configuration word needs to be replaced. At this time, the obtained class reset configuration word may be written into the memory to replace the basic reset configuration word at the head of the first boot file, and in the boot file after replacement, the basic reset configuration word at the head is replaced with the class reset configuration word 1 corresponding to the board 1, as shown in fig. 4, which may be referred to as a second boot file.
And S108, restarting the board, acquiring a second boot file in the memory, and initializing the board through the second boot file.
After the replacement is completed, the processor needs to restart the board, because the reset configuration word needs to be configured at the time of starting and cannot be modified again before the board is powered down once the reset configuration word is configured, the board needs to be restarted to complete the configuration for each board.
And after the single board is restarted, the processor reads the second boot file from the memory and initializes the single board according to the second boot file.
At this time, since the replacement of the reset configuration word has already been completed for the board, in the subsequent initialization process, when the classification reset configuration word for the board is read again according to the board identifier, the comparison with the basic reset configuration word at the head of the first boot file is consistent, and the replacement is not required again. In this way, the initialization process is continuously performed, thereby completing the initialization process of the board.
That is to say, in the boot file stored in the memory on the board, the reset configuration word at the head may be consistent with the classified reset configuration word carried in the boot file, and the replacement may not be executed in case of consistency, the initialization of the board is directly completed based on the current boot file, the replacement is executed and the board is restarted in case of inconsistency, and then the initialization of the board is completed through the replaced boot file.
In the embodiment of the present specification, by setting the basic reset configuration word for performing the initial initialization of the board and the classified reset configuration words for the boards of the multiple types in the boot file, in the process of the initial initialization, the classified reset configuration word corresponding to the board identifier is used to replace the basic reset configuration word, and the initialization is performed again, so as to implement the initialization for the board of the specific type, avoid the need to store the boot file of the corresponding type for each type of board, and reduce the occupation of the network device space when the boot files of the multiple types need to be stored. In addition, for the staff, only one version of the guide file can be edited, and the method and the device can be suitable for various single boards, so that the efficiency of network equipment configuration is improved.
Optionally, the first bootstrap file may further include a default reset configuration word, where the default reset configuration word is used for default configuration of the single board, that is, when the corresponding classification reset configuration word cannot be found through the single board identifier, the default reset configuration word is selected to initialize the single board.
After acquiring the board id of the board, in step S104, if the classified reset configuration word corresponding to the board id cannot be found in the first boot file, the default reset configuration word in the first boot file is acquired, and in step S106, the default reset configuration word is replaced with the basic reset configuration word in the first boot file. After the board is restarted, the initialization of the board is carried out through the boot file replaced by the default reset configuration word.
Optionally, in step S104, after obtaining the board identifier of the board, if the classification reset configuration word corresponding to the board identifier cannot be found in the first boot file, the initialization of the board may be completed directly through the basic reset configuration word and the boot program without replacing the basic reset configuration word.
After the processor acquires the first boot file stored in the memory on the board, the method further comprises the following steps:
S101A, determining the version number of the first boot file.
The version number may be a file name of the first boot file or a field marked in the first boot file, which is not limited.
And S101B, sending a request message to the main control board.
After the version number of the first boot file is obtained, it is necessary to determine whether the current version number is the latest version, so that the processor generates a request message, carries the version number into the request message, and sends the request message to the main control board through inter-board communication between the single board and the main control board.
At this time, after receiving the request message, the main control board may analyze a version number therein, and compare the version number with a version number of the upgrade boot file stored in a memory of the main control board.
When the main control board determines that the version number in the request message is consistent with the version number of the upgrade boot file stored in the main control board, the single board is informed through the feedback message that the version of the first boot file stored in the single board is the latest version, and when the version number in the request message is inconsistent with the version number of the upgrade boot file stored in the single board, the upgrade boot file starts to be transmitted through a bus between the main control board and the single board.
And S101C, receiving the upgrade guide file issued by the main control board, and replacing the first guide file in the memory.
And S101D, restarting the board, and initializing the board according to the upgrade boot file.
And after receiving the upgrade guide file sent by the main control board, initializing the board through the upgrade guide file. The specific initialization process is similar to the above steps S100 to S108, and will not be described again.
Through steps S101A-S101D, the boot file on the board may be upgraded, so that the board may be started through the latest boot file. When the version number of the boot file stored in the single board is inconsistent with the version number of the boot file stored in the main control board, the time consumed for storing multiple boot files in the memory of the main control board can be reduced, and the efficiency of upgrading the single board in the network equipment is improved.
A specific embodiment of the present invention is described below with reference to a board startup method, which includes:
s1, the single board receives power supply of a power supply, and a processor is started.
S2, the processor of the single board conducts early stage guiding, and data communication between the single board devices is achieved.
The above steps S1 and S2 are similar to the existing processing flow, and will not be described herein. The structure of the network device is shown in fig. 5, at this time, communication between the processor and the register (not shown) of the board and communication in the memory can be realized, and data in the register and the memory can be acquired. The same boot file, called boot file 1, is stored in the board 1 and the same boot file, called boot file 2, is stored in the main control board. The processor in the board 1 is referred to as a processor 1, the memory is referred to as a memory 1, the processor in the board 2 is referred to as a processor 2, the memory is referred to as a memory 2, the processor in the main control board is referred to as a processor 3, and the memory is referred to as a memory 3.
And S3, the processor of the single board reads the boot file from the memory, loads the boot file into the memory, and starts initialization according to the boot file.
As shown by the dotted arrow in fig. 5, the boot file 1 is loaded into the memory for processing, and the initial configuration is performed on the board through the basic reset configuration word in the boot file 1. At this time, the plate communication between the single plates 1 and 2 and the main control board can be realized through the basic reset configuration words.
And S4, the processor of the single board sends a request message to the main control board according to the version number of the guide file.
When the processors 1 and 2 acquire the boot file 1, the version number of the boot file 1, such as V1.2, may be determined, and the processors 1 and 2 carry the version number to a request message and send the request message to the main control board.
And S5, the processor of the main control board receives the request message sent by the single board and acquires the version number carried in the request message.
S6, the processor of the main control board compares the version number carried in the request message with the version number of the guide file stored in the memory of the processor of the main control board, if the version number is consistent with the version number of the guide file stored in the memory of the processor of the main control board, a feedback message is sent to the single board to inform the single board that the guide file is the latest version, the step S8 is skipped, and if the version number is inconsistent with the version number, the guide file stored in the processor of the main control board is sent to the single board, and the step S7 is skipped.
And S7, when the processor of the single board receives the guide file issued by the main control board, replacing the guide file in the memory of the single board by the received guide file, and restarting the single board.
As shown in fig. 6, the boot file 1 stored in the memory 1 is replaced with the boot file 2 stored in the memory 3 of the main control board. After step S7 is executed, which is equivalent to the process of restarting the board, the process will jump back to step S1 for initialization.
And S8, when the processor of the single board receives the feedback message, continuously executing initialization according to the self guide file.
At this time, processor 1 of board 1 re-executes the initialization process, and the description is not repeated here.

The description is made here taking the single board 2 as an example. In the register of the board 2, a board identifier of the board is stored, and a corresponding relationship between the board identifier and the reset configuration word in the boot file is also stored. The board identifier of board 1 is identifier 1, and the board identifier of board 2 is identifier 2. As shown in fig. 6, a sort reset configuration word 1 and a sort reset configuration word 2 are respectively configured in the boot file 1 and the boot file 2, wherein the sort reset configuration word 1 corresponds to the identifier 1, and the sort reset configuration word 2 corresponds to the identifier 2.
S10, the processor of the single board searches the corresponding reset configuration word in the guide file according to the single board identification, if the basic reset configuration word in the guide file corresponds to the single board identification or the corresponding classified reset configuration word is not found in the guide file, the step S11 is skipped, and if the basic reset configuration word is found, the step S12 is skipped.
And S11, the processor of the single board completes the initialization of the single board according to the basic reset configuration word and the bootstrap program.

After that, the board 2 is restarted, and the step S1 is skipped to restart the initialization.
In the embodiment of the present specification, by setting the basic reset configuration word for performing the initial initialization of the board and the classified reset configuration words for the boards of the multiple types in the boot file, in the process of the initial initialization, the classified reset configuration word corresponding to the board identifier is used to replace the basic reset configuration word, and the initialization is performed again, so as to implement the initialization for the board of the specific type, avoid the need to store the boot file of the corresponding type for each type of board, and reduce the occupation of the network device space when the boot files of the multiple types need to be stored.
