Detailed Description
The core of the application is to provide a setting selection circuit, a method, an electronic device and a computer readable storage medium for a mainboard device in a server, so as to effectively save the circuit layout space and improve the circuit maintenance efficiency.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
A dip switch is a common device in electronic circuit design. Currently, dial switches are also often used in the design of motherboard circuits of servers to perform setting input on some motherboard devices, for example, the dial switches are used to select relevant setting values of BIOS or BMC. Moreover, in some development projects such as the Whitley platform project, the initial settings related to the BIOS and the BMC are so many that basically two to three dial switches are required to be used on each motherboard.
However, since the volume of the dial switch is large and a front installation is required and a manual operation space is reserved, a large PCB layout space is occupied. In addition, the dial switch is not only easy to have the problems of not-in-place poking and poor contact in use, but also needs to be manually modified and maintained after the casing is disassembled for any modification, which is troublesome. In view of this, the present application provides a setting selection scheme for a motherboard device in a server, which can effectively solve the above problems.
Referring to fig. 1, an embodiment of the present application discloses a setting selection circuit for a motherboard device in a server, which is used to replace a dial switch to perform setting selection on the motherboard device, and mainly includes:
the storage module 101 is used for pre-storing signal setting values of the main board device in different time states;
the logic module 102 is connected with the storage module 101 and is used for reading a signal set value corresponding to the current time state from the storage module 101 after being powered on and sending the signal set value to the I2C GPIO expansion port integrated chip 103 for outputting;
and the I2C GPIO expansion port integrated chip 103 is connected with the logic module 102 at the input end and the mainboard device at the output end, and is used for outputting a signal set value corresponding to the current time state to the mainboard device so as to perform setting selection.
It should be noted that, the setting selection circuit provided in the present application specifically uses I2C GPIO expansion port integrated chip 103, i.e., I2C GPIO Expander IC, to perform the selection setting instead of the dial switch. Compared with a dial switch, the I2C GPIO Expander IC has small volume and high signal density, and does not need manual setting.
Specifically, the I2C GPIO IO Expander IC can control 16-bit signals and has a volume smaller than that of a dial switch with eight switch signals, so the signal density of the I2C GPIO Expander IC is much higher than that of the dial switch. In addition, the I2C GPIO Expander IC does not need to be manually shifted, any position of the front surface and the back surface of the I2C GPIO Expander IC can be placed, and the elasticity of the installation mode is far greater than that of a dial switch directly used. Moreover, when the I2C GPIO Expander IC is modified, the setting can be modified in a software mode without disassembling the shell, the later maintenance is more convenient, and the accuracy is high; the dial switch must be manually modified to modify the setting value, and the manual setting mode has a high yield risk under the condition of large-scale factory shipment.
Therefore, the related memory module 101 and the logic module 102 on the mainboard can be fully utilized, and an I2C GPIO Expander IC is used in cooperation, so that a dial switch is replaced, and the setting selection of the mainboard device is realized.
The memory module 101 may be divided into a fixed memory area for storing preset signal values, i.e. signal setting values, which should be output by the I2C GPIO Expander IC in different time states. After power-on, the logic module 102 automatically reads and fills the signal setting value stored in the storage module 101 into an internal register of the logic module 102, and when the logic module 102 is in the corresponding time state, the signal setting value corresponding to the current time state is sent to the I2C GPIO Expander IC and is output to the motherboard device by the I2C GPIO Expander IC.
It should be noted that the reason why the present application does not directly use the set value of the signal output by the IO port of the logic module 102 to the motherboard device is that the cost of directly using the IO port of the logic module 102 such as CPLD/FPGA is much higher than that of using the GPIO Expander of I2C. Generally, the conventional logic module 102 is powerful, its package size is fixed and large, and the chip layout installation is limited. The circuit design scheme using the I2C GPIO Expander IC is far more elastic than the IO directly using the logic module 102, the I2C GPIO Expander ICs with corresponding quantity can be selected to be connected in parallel according to the quantity of the required GPIO interfaces, each I2C GPIO Expander IC can be dispersedly placed on a PCB according to the layout space, and only the I2C slave address (slave device address) needs to be staggered.
In addition, it should be noted that the reason why the signal setting values are stored in the storage module 101 rather than the logic module 102 in the present application is that if the signal setting values are stored in the logic module 102, the codes of the entire logic module 102 need to be modified when the setting needs to be modified, and any code modification in subsequent production needs to be verified for a long time, which causes unnecessary program verification and reduces efficiency. Therefore, the signal setting value is stored in the storage module 101 in advance, the problem that the code in the logic module 102 is modified when the signal setting value is modified can be solved, and the maintenance efficiency of the equipment is improved.
Therefore, the setting selection circuit of the main board device in the server disclosed by the embodiment of the application replaces a dial switch which is large in size and needs to be manually modified based on the I2C GPIO Expander IC with high signal density, can effectively save the circuit layout space of a PCB on the basis of completing the selection setting of the main board device, improves the signal quality and the subsequent maintenance efficiency, and accelerates the mass production test period of products.

Specifically, in this embodiment, based on the remote communication function of the Baseboard Management Controller (BMC), the BMC may be used to temporarily modify the signal setting value output by the I2C GPIO Expander IC: by communicating remotely with the BMC, the BMC may be enabled to write a signal update value to an internal register of the logic module 102, which in turn may be used by the logic module 102 to modify the output of the I2C GPIO Expander IC.
Therefore, the remote setting modification method can realize remote setting modification, greatly improve maintenance efficiency and have great advantages in remote maintenance application.
