Description
Technical Field
The invention relates to the field of communication, in particular to a loading technology of single-board firmware.
Background
The IPMI (Intelligent Platform Management Interface) standard is a new generation of universal Interface standard for providing a server with Intelligent Management, and can provide functions such as device Management, sensor/event Management, user Management, fan frame/power frame Management, remote maintenance, and the like for the server.
The "intelligence" of IPMI technology comes from a management microcontroller. In a host system, this Controller is called BMC (Baseboard Management Controller). The BMC is self-contained and automatically monitors system health. If any of the controlled units is found to be abnormal, it can take immediate action, such as logging an event, alarming, auto-shutdown or restart. Associated with the BMC is a set of passive memories for storing Sensor Data (SDR), system event log files, and some unit information such as serial number and part number information. IPMI transmits information to a management microcontroller by specifying a generic, streamlined, message-based interface, enabling separation of software and hardware information. The IPMI technique thus allows monitoring and control of the hardware platform independent of the host processor. For example, a user may utilize the IPMI to monitor the physical characteristics of the server, such as temperature, voltage, fan operating status, power supply, and chassis intrusion, to provide information for system management, recovery, and asset management.
As the functional requirements of people on communication are increasing, some single board firmware needs to be upgraded, and the single board firmware needs to be loaded in the upgrading process.
The first prior art related to the present invention provides a method for locally loading a firmware on a board, which has the core that: and loading the single board firmware by using a special tool through an interface of the single board firmware. For example, the firmware of CPLD (Complex Programmable logic Device) can be loaded through JTAG (boundary scan test interface) interface connected to computer, or the firmware of FLASH can be written by burn-in machine.
In the prior art, a single board needs to be detached from a machine frame, even firmware needs to be detached from the single board, and a special loading tool is used for loading the firmware of the single board, so that the operation is complex, and difficulty is brought to upgrading and maintaining the firmware of the single board.
The second prior art related to the present invention proposes another method for locally loading the firmware of the single board, which has the core: and loading the single board firmware connected to the CPU through the CPU of the host. For example, the FLASH firmware can be loaded through a CPU connected to the FLASH firmware on the single board.
In the second prior art, the board firmware connected to the host can only be locally loaded through the host software, but cannot be remotely loaded through the host.
The third prior art related to the present invention provides a method for implementing remote loading, which requires a CPU connected with firmware to communicate with a remote management system, and the core of the method is as follows: the CPU communicates with a remote management system and obtains loaded software, and then the CPU loads the loaded software onto the firmware.
In the third prior art, although the board firmware connected to the CPU can be remotely loaded, if the board firmware to be loaded is connected to different CPUs, each CPU needs to be configured to have a function of communicating with a remote management system, so that the loading interfaces are not uniform, and the implementation is complex.
It can be seen from the above prior art that, the first and second prior art can only implement loading of local board firmware, and when remote loading is to be implemented, a CPU connected to different board firmware to be loaded has a function of communicating with a remote management system, and at this time, the loading interfaces are not uniform, which is difficult to implement.

The eighth embodiment of the present invention is a second method for implementing remote loading of firmware on a board, and the difference between the second embodiment and the seventh embodiment is: the method can only load the firmware on one single board. The method comprises the following specific implementation processes:
step 1, an IPMI data message carried by a protocol suitable for long-distance transmission is sent to a baseboard management controller BMC of a target single board through a remote management system.
And 2, converting the received IPMI data message into an IPMI data message carried by a single board local protocol by the BMC, and loading local single board firmware according to the converted data message.
In step 2, if the firmware that needs to be loaded in the board is connected to the processor module, the processing procedure in step 2 is as follows:
the BMC converts the received IPMI data message into an IPMI data message carried by a single board local protocol, and obtains a control command and data required by firmware loading from the IPMI data message carried by the local protocol; and transmitting the obtained command and data to a processor module;
the processor module judges the firmware to be loaded according to the control command, converts the loading data required by the firmware into a format required by a loading interface of the firmware, and then transmits the loading data to the loading firmware through the loading interface for loading.
If the firmware to be loaded in the board is directly connected to the BMC, the processing procedure of step 2 is as follows:
the BMC converts the received IPMI data message into an IPMI data message carried by a single board local protocol, acquires a control command and data required by firmware loading from the IPMI data message carried by the local protocol, judges the firmware required to be loaded according to the control command, converts the loading data required by the firmware into a format required by a loading interface of the firmware, and then transmits the loading data to the loading firmware through the loading interface for loading.
If the firmware to be loaded in the board is embedded in the BMC, the processing procedure of step 2 is as follows:
the BMC converts the received IPMI data message into an IPMI data message carried by a single board local protocol, obtains a control command and data required by loading of the control command from the IPMI data message carried by the local protocol, and loads bottom-layer firmware arranged in the BMC according to the control command by using the loading data.
According to the specific implementation mode of the invention, the remote loading of the firmware of the single board is realized through the IPMI technology, the hardware platform interface can be standardized, the maintenance and the upgrade are convenient, and the reliability, the expandability and the transportability are better; and the development period can be shortened, and the development cost can be reduced. Moreover, the invention can enable the power supply of an IPMI subsystem, such as BMC, to exist independently from the CPU system based on the IPMI technology, and when the CPU system fails, the BMC can still operate.
In addition, the invention converts the IPMI message transmitted from the remote end into the IPMI message which can be identified by each single board through the system management module, thereby providing a uniform IPMI interface to load the firmware on a plurality of single boards.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
