Before describing the present invention specifically, it is necessary to describe the hardware structure of the present invention specifically, as shown in fig. 1, the cluster server of the present invention includes a main board 1 and a plurality of daughter board devices 2, where the daughter board devices 2 are connected to the main board 1 through built-in USB lines and ethernet lines. Traditional USB line and ethernet cable all are walked the line through the PCB board and are replaced for the integrated level of circuit board is high, stability is good. Both motherboard and daughter board devices can be considered as independent computer hosts, each having their own CPU, memory, internal eMMC storage, network interfaces, etc. The daughter board devices 2 are connected to the Web server through a network interface such as an ethernet cable to acquire data from the Web server.
The embodiment of the invention provides a firmware upgrading method of a cluster server, which can refer to a flow chart shown in fig. 2, and comprises the following steps:
S100: the main board writes auxiliary firmware into the daughter board equipment through the USB line, and the daughter board equipment restarts according to the auxiliary firmware. The auxiliary firmware is prefabricated on the main board, the auxiliary firmware comprises an upgrading tool and upgrading parameters required by upgrading the firmware of the daughter board equipment, the auxiliary firmware is programmed into the daughter board equipment through a built-in USB (universal serial bus) line, and the daughter board equipment loads and operates the firmware and restarts to prepare for upgrading the firmware. For a daughter board device that has partially run firmware, the daughter board device needs to be switched to Loader mode.
S200: after restarting the daughter board device, the main board sends upgrade configuration parameters to the daughter board device, and the daughter board device configures an upgrade environment according to the upgrade configuration parameters. The main board detects the state of the daughter board device, and after the daughter board device is restarted, the upgrade configuration parameters are sent to the daughter board device, the daughter board device performs network configuration of an upgrade environment, and an upgrade program can be modified.
S300: the daughter board device sends a firmware upgrade request to the Web server through the Ethernet line. After the configuration of the upgrading environment is successful, the daughter board device sends a firmware upgrading request to a preset Web server through an Ethernet cable so as to request to upgrade the firmware. The Web server may verify the legitimacy of the request, e.g., the request is legitimate, and the Web server may send firmware data to the requesting daughter board device.
S400: the daughter board device receives the firmware data fed back by the Web server, and can burn the received firmware data into the memory in real time so as to upgrade the firmware.
In one embodiment, the auxiliary firmware includes a kernel of Ubuntu firmware, a root file system customized using Buildroot, and upgrade parameters including a path to upgrade the firmware. The inherent Ubuntu firmware kernel of the daughter board device is reused, the kernels of other firmware are not required to be additionally called, and the complexity of project compiling can be reduced. The upgrade parameters include a path to upgrade the firmware, thereby upgrading the specified firmware. The root file system is customized using Buildroot, adding necessary functions, such as an adb support function and a rkupdate support function, which can reduce the volume of auxiliary firmware.
Specifically, buildroot is customized based on the warehouse of the motherboard chip factory. The main modifications are: 1. minimized Buildroot configurations, containing only the essentially required functions, including adb, busy box, rkupdate, etc.; 2. the startup automatically executes a preset script, specifically a/usr/bin/netrecovery script, and the/usr/bin/netrecovery script is responsible for extracting an embedded tar.gz package from a misc partition, decompressing the embedded tar.gz package to a/tmp directory, and running the/tmp/netrecovery script therein. The/tmp/netrecovery script contains the primary upgrade operations, which need to be modified frequently, and thus is provided by the auxiliary firmware, obviating the need to compile Buildroot root file system; 3. the dependency library libcurl is installed for http support.
In one embodiment, the auxiliary firmware is packaged as follows: packaging all files in the tar/directory into a tar.gz package, adding the tar.gz package into res/wipe_all-risc.img as a risc partition firmware file, decompressing the tar.gz package to the/tmp directory when auxiliary firmware is started, and automatically executing the/tmp/netrecovery script; decompressing res/boot. Img files in Ubuntu firmware, prompting kernels and resource files, and packaging the res/boot. Cpio. Gz files together with a root file system package res/recovery. Cpio. Gz generated by Buildroot to obtain a recovery. Img file; and finally, packaging the firmware files of all the partitions into final auxiliary firmware.
In one embodiment, for an arm64 architecture motherboard, the motherboard vendor provides open source programs, such as rkdeveloptool programs. When the mainboard writes auxiliary firmware into the daughter board equipment through the USB line, a rkdeveloptool program on a PC connected with the mainboard is transplanted to a host and runs; the program rkdeveloptool is modified, the firmware file programming function is added, the firmware file programming function comprises the switching of a starting mode (namely, how to switch a Loader mode to a Maskrom mode) and the programming of the firmware file, the multithreading support function is also added, and the programming can be performed on a plurality of USB devices at the same time, so that the bandwidth is fully utilized, and the programming efficiency is improved. Further, with the support of SPARSE IMAGE (loose image), the conventional ext4 image file contains a large amount of void space, i.e. space occupied by the image file but not providing valid data, and the loose image compresses the space, so that the size of the image file is significantly reduced.
In one embodiment, for a part of the motherboard, buildroot SDK provided by the factory contains the source code of rkupdate program, and the program can write the firmware file on the local TF card into the eMMC memory, which belongs to the traditional firmware upgrade measure. Thus, in using the present invention, support for the network is added. The network support can mount the file system at the far end of the network to the local by using the NFS, so rkupdate can support network programming without any modification, but in the actual operation process, the NFS server is complicated to configure, the daughter board devices also need the kernel to open the corresponding client functions, the quantity of the daughter board devices is more, the performance of the NFS is obviously reduced, and the resource competition can occur, so that the blocking situation occurs.
Therefore, in step S200, the daughter board device configures the upgrade environment according to the upgrade configuration parameters, specifically modifies rkupdate programs, specifically increases HTTP support, so that NFS configuration is avoided, resource usage of an external Web server can be supported, and the daughter board device is more flexible and convenient to debug. At the same time, SPARSE IMAGE support is also added.
For the existing firmware upgrading mode, after upgrading is completed, an upgrading result cannot be intuitively known. Whether the daughter board devices are successfully upgraded can only be checked one by one through the line lifting software of the system, and the operation mode is obviously very complicated. In one embodiment, after step S400, the method further includes the following steps: after the firmware is successfully upgraded, the daughter board equipment feeds back upgrade success information to the main board or controls a preset LED lamp on the daughter board equipment to flash.
Netrecovery-slave scripts can be made, and the scripts mainly define APIs of the upgrading interfaces of the daughter board devices, so that the mainboard can conveniently call and acquire operation results. The main board can send corresponding commands, and the daughter board equipment feeds back corresponding results according to the commands. For the get-state command beginning with get_and if the state get is successful, the daughter board device returns an execution result, otherwise returns an "error", and begins with long operation command beginning with long_and the daughter board device will return a process number to make subsequent state query, long operation is a long time consuming operation, such as writing firmware, the progress of which will be parsed and stored in a designated file for subsequent state query. For other short operation commands, the daughter board devices return only the "okay" or "error" done or not flag.
The auxiliary firmware can also comprise pin numbers of the preset LED lamps on the daughter board equipment, and when the daughter board equipment successfully upgrades the firmware, the daughter board equipment sends corresponding control signals to the pins so as to control the LED lamps to flash, wherein the flashing mode comprises long-lighting, slow-flashing, flash and the like, so that the firmware upgrading result is intuitively reflected.
The embodiment of the present invention also provides a cluster server, as shown in fig. 1, including a main board 1 and a plurality of daughter board devices 2, where the main board 1 and the daughter board devices 2 are used to execute the firmware upgrade method of the cluster server, and reference may be made to the embodiment of the firmware upgrade method part of the cluster server.
The foregoing is a further detailed description of the invention in connection with specific embodiments, and it is not intended that the invention be limited to such description. It will be apparent to those skilled in the art that several simple deductions or substitutions can be made without departing from the spirit of the invention.
