Background

Often, the board card needs to be upgraded after leaving the factory, and the upgrading modes generally comprise two modes: local upgrades and remote upgrades. The local upgrading mode requires that a worker burns files on site at the position of the board card, and the board card is required to be detached from the equipment in part of scenes, so that the local upgrading mode is inconvenient, batch upgrading cannot be realized, and the efficiency is low. Remote upgrade refers to a technical means for remotely upgrading and updating a board card by using a computer network or other remote communication modes.

Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

In the related art, a board card is a single board of a computer, and an operating system generally uses a storage medium for storage. Compared with a common desktop operating system, the operating system of the board card has the characteristic of small size. The storage medium is typically firmly soldered to the motherboard. The board card may be plugged onto some electronic device (which may be referred to as a business device).

The local upgrade requires an operator to go to the site, and uses an upgrade tool (such as a serial port line or a Jlink burner, etc.) to connect with service equipment, and burn an upgrade file onto a board card through a series of operation commands to complete the upgrade. And part of the boards are internally provided with a storage medium detection function, and operators can access the storage devices (such as an SD card, a U disk or a mobile hard disk) stored with the upgrade files into the boards, and the boards automatically complete copying of the upgrade files and upgrading operation of an operating system by detecting the designated files in the storage medium when restarting.

The local upgrade mode requires operators to go to the site, and even requires that the electronic device be removed from the rack and the chassis of the electronic device be opened, since the Jlink access terminals of most devices are internal to the device. Therefore, the local upgrade mode is very inconvenient for most field scenes, and batch upgrade cannot be performed.

Common remote upgrade modes include upgrade at the U-Boot startup stage or upgrade at the operating system running stage.

Strictly speaking, the upgrade is realized in the U-Boot starting stage, which essentially belongs to one of local upgrades, and requires an operator to go to the site, access a serial port line and restart the board card. After the U-Boot is started, the U-Boot enters a man-machine interaction mode through serial operation. An operator sets an IP address of the board card and an IP address of the upgrade server in an interactive mode, builds the upgrade server, and ensures that the board card and the upgrade server can be connected through a communication network. The upgrade file is downloaded into the memory of the board card using a U-Boot network protocol (typically TFTP protocol or FTP protocol) command, then the target area of the memory space of the board card is erased using a Flash erase command, and then the upgrade file is written into the target area.

In the U-Boot starting stage, an operator is required to go to the site, a serial port line (used for operating the electronic equipment) and a network line (used for connecting an upgrading server) are required to be connected to a panel of the electronic equipment, and batch equipment upgrading cannot be realized.

The upgrade is a real remote upgrade mode in the operation stage of the operating system, and no operator is required to go to the site, and no serial port line or network line is required to be inserted.

Taking the example of the operating system currently deployed in zone a 102 in fig. 1, the process of remotely upgrading the board card may include the steps of:

after the operation system of the board card is started, an operator can log in the operation system through a remote login tool;

downloading the upgrade file to the board card based on a network communication protocol (which may include, but is not limited to, TFTP or FTP, etc.);

verifying and deploying the upgrade file in the region B103 in FIG. 1;

restarting the operating system, starting the boot loader, and reading the boot loader parameters;

the boot loader directs the operating system of zone B103 to boot up according to the boot parameters.

The memory space required by the operating system of the board card is typically several GB, so that about half of the memory space of the dual-region storage operating system (compared to the operating system, the memory space occupied by the boot loader is typically small, only several tens of MB) is wasted, and the boot loader cannot be upgraded.

The method for remotely upgrading the board card, the device for remotely upgrading the board card, the electronic equipment and the readable storage medium provided by the embodiment of the application are described in detail below through specific embodiments and application scenes thereof with reference to the accompanying drawings.

The method for remotely upgrading the board card can be applied to the board card and the management end, and can be specifically executed by hardware or software in the board card and the management end.

The managing end includes, but is not limited to, a portable communication device such as a mobile phone or tablet having a touch sensitive surface (e.g., a touch screen display and/or a touch pad). It should also be appreciated that in some embodiments, the managing end may not be a portable communication device, but rather a desktop computer having a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In the following various embodiments, a management end including a display and a touch-sensitive surface is described. However, it should be understood that the management end may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.

Fig. 2 is a schematic diagram of an architecture of a memory space of a board card according to an embodiment of the present application. As shown in fig. 2, the memory space of the card in the embodiment of the present application may be divided into two parts, where the two parts are a first memory area 201 and a second memory area 202, respectively. The first storage area 201 may be used to store a business operating system. The service operating system is equivalent to the operating system stored in the a area 102 or the B area 103 in the related art, and is used for implementing various services carried by the board card. A second storage area 202 for storing firmware.

The firmware may include two parts: the loader and the communication operating system are booted. Different from the service operation system, the communication operation system only needs to meet the condition of realizing the communication function between the board card and other devices, and does not need to bear other services. Thus, the capacity of the storage space occupied by the communication operating system may be only a few to tens of MB, which is much smaller than the capacity of the storage space occupied by the business operating system. Typically, the firmware occupies less than 64MB of memory. It should be noted that the firmware must be burned as a whole, and not separately burned.

In some embodiments, to ensure security, the communication operating system may be a read-only operating system.

In some embodiments, the firmware may be deployed in a separate storage medium (e.g., nor Flash, etc.), or may be deployed in the same storage medium as the business operating system (e.g., eMMC Flash). That is, the first storage area 201 and the second storage area 202 may physically belong to the same storage medium or may belong to different storage media.

In some embodiments, the board card itself may communicate with external devices such as a management end through a communication network, or with external devices such as a management end through the electronic device.

Fig. 3 is a schematic flow chart of a method for remotely upgrading a board card according to an embodiment of the present application. In some embodiments, as shown in fig. 3, a method for remotely upgrading a board card may include:

step 301, the management end issues a remote upgrade start command to the board card.

An operator can log in the management end, and send a remote upgrade starting command to the board card through the management end.

Step 302, the board card receives a remote upgrade start command, and modifies the target guided by the boot loader into a communication operating system by the service operating system.

The board card may receive a remote upgrade start command based on a communication link between the management side and the board card.

After the board card receives the remote upgrade start command, a corresponding response can be made to modify the boot loading parameters of the boot loader. The modified bootloading parameter indicates that the bootloader bootstraps the communication operating system, and thus the goal of the bootloader boot is changed from the business operating system to the communication operating system.

Step 303, the board runs a boot loader, and starts a communication operating system.

The board card is restarted to run the boot loader. Since the target of the bootloader boot has been modified to the communication operating system, the communication operating system boots. It will be appreciated that the business operating system is not started at this time.

Step 304, the management end issues a command for downloading the upgrade file to the board card.

Because the communication operation system can bear the communication function between the board card and other devices, after the communication operation system is started, the communication link between the management end and the board card is recovered, so that the management end can issue a command for downloading the upgrade file to the board card.

The management end can send the command of downloading the upgrade file to the board card after sending the preset time length of the remote upgrade starting command or after receiving the received indication of the remote upgrade starting command sent by the board card.

The command for downloading the upgrade file may carry an address of a target server storing the upgrade file, a communication protocol used for downloading the upgrade file, a name of the upgrade file, and the like.

The communication protocol used to download the upgrade file may include, but is not limited to, TFTP (Trivial File Transfer Protocol, simple file transfer protocol), FTP (File Transfer Protocol ), SCP (Secure Copy Protocol, secure copy protocol), or the like.

In some embodiments, the upgrade file includes at least one of a first image file of the new firmware and a second image file of the new business operating system.

Step 305, the board receives the command of downloading the upgrade file, downloads the upgrade file from the target server and writes the upgrade file into the memory space of the board.

After receiving the command for downloading the upgrade file, the board card can respond correspondingly, connect the target server based on the address, and download the upgrade file of the name based on the communication protocol.

After the upgrade file is downloaded, the upgrade file can be written into a corresponding storage area in the storage space of the board card.

In some embodiments, in the case that the communication operating system does not carry the file reading and writing function, the upgrade file may be written into a corresponding storage area in the storage space of the board card by means of burning. Under the condition that the communication operating system bears the file reading and writing function, the upgrade file can be written into a corresponding storage area in the storage space of the board card in a disk reading and writing mode.

The storage area corresponding to the first image file is the first storage area 201. The storage area corresponding to the second image file is the second memory area 202.

Step 306, the management end issues a remote upgrade end command to the board card.

The management end can send a remote upgrade ending command to the board card after sending the preset time for downloading the upgrade file or after receiving the indication that the upgrade file sent by the board card is downloaded.

Step 307, the board receives the remote upgrade ending command, and modifies the target guided by the boot loader to the service operating system by the communication operating system.

After the board card receives the remote upgrade end command, a corresponding response can be performed to modify the boot loading parameters of the boot loader again. The modified boot loading parameters indicate that the boot loader guides the service operating system, so that the target guided by the boot loader is changed from the communication operating system to the service operating system.

Step 308, the board runs a boot loader and starts a service operating system.

The board card is restarted to run the boot loader. Since the target of the bootloader boot has been modified to the business operating system, the business operating system boots. Through the above process, at least one of the firmware and the business operating system is updated, and the upgrade is completed.

In the embodiment of the application, the receiving and writing of the upgrade file are independent of the operation of the service operation system, so that the service operation system after upgrade and the service operation system before upgrade can be stored in the same storage area, and another storage area is not required to be reserved for the upgrade of the service operation system. Because the capacity of the storage space occupied by the communication operating system is far smaller than that of the service operating system, a large amount of storage space can be saved compared with the mode of storing the service operating system in double areas.

In addition, the embodiment of the application does not need operators to go to the field for operation, only needs to log in the management end, and can be operated remotely, so that the method is very convenient, and the batch upgrading of the boards can be realized.

The embodiment of the application does not need to be connected with a serial port line, a Jlink burner and the like, and is very suitable for a scene that once equipment is deployed, the equipment is contacted and even disassembled very inconveniently.

It should be noted that, in the process of remote upgrading the board card, the management end may directly communicate with the board card to issue various commands (such as a remote upgrade start command, a download upgrade file command, and a remote upgrade end command).

In some embodiments, the management end may not directly communicate with the board, but transit through the service electronic device, and transmit various commands, where the board directly communicates with the target server, so as to implement separation of the management data stream and the service data stream.

Fig. 4 is a schematic diagram of a communication architecture of a method for remotely upgrading a board card according to an embodiment of the present application. As shown in fig. 4, the service device may include an external switching chip 401, an internal switching chip 402, a management module 403, and at least one connector 404.

The external switch chip 401, the internal switch chip 402, the management module 403, and the connector 404 may be disposed inside a chassis of the service device. The card may be inserted into connector 404 to connect with the business device.

The management module 403 and the board may each have 2 communication links, one to access the internal switching chip 402 and the other to access the external switching chip 401. An internal exchange chip 402, configured to carry a communication function between the management module and the board card, and not interact with an external object of the service device; the external exchange chip 401 is used for carrying management communication between the management module and the management end and carrying external communication functions of the board card.

It should be noted that, interaction with an external object of the service device, and external communication refer to communication with an object other than the service device. The card is inserted into the connector 404 inside the chassis of the service device, and thus is not considered as an object outside the service device.

Therefore, the path of the management end for issuing the command to the board may be: management end- > ethernet- > external exchange chip 401- > management module 403- > internal exchange chip 402- > board card.

The response path of the board card to the management end command can be: board- > internal exchange chip 402- > management module 403- > external exchange 401- > Ethernet- > management side.

Fig. 5 is a second flowchart of a method for remotely upgrading a board card according to an embodiment of the present application. As shown in fig. 5, the method for remotely upgrading the board card based on the above communication architecture may include:

Step 501, the management end issues a remote upgrade start command to the management module.

Step 502, the management module forwards the remote upgrade start command to the board card.

Step 503, the board modifies the boot loading parameters.

The board card modifies the boot loading parameters of the boot loader. The modified bootloading parameter indicates that the bootloader bootstraps the communication operating system, and thus the goal of the bootloader boot is changed from the business operating system to the communication operating system.

Step 504, the board replies a first message to the management module.

After the boot loading parameters are modified, the board card can respond to the remote upgrade start command, reply a first message to the management module, and reply to receive the remote upgrade start command.

Step 505, the management module forwards the first message to the management end.

Step 506, the management end issues a reset board card command to the management module.

Step 507, the management module resets the board.

The management module may RESET (RESET) the central processing unit (Central Processing Unit, CPU) pins of the board, causing the board to restart.

Step 508, the board loads the communication operating system into the memory, starts the communication operating system, and obtains the second IP address.

After restarting the board, the BootLoader program copies the communication operating system into the memory according to the modified boot loading parameters and guides the communication operating system to start. And the communication operation system calculates a second IP address according to the slot number of the board card.

The board card comprises two net openings: the first network port and the second network port. The second portal and the second IP address are for internal communication. The IP address of the second network port is a second IP address. Internal communication refers to communication between the board card and the management module.

Step 509, the board reports the board information.
