Method and system for identifying information of single plate hardware version

Abstract

The invention discloses a system for identifying information of single plate hardware version, comprising an information network unit and an information receiving and processing unit; wherein the information network unit is used for providing hardware version information and outputting the hardware version information to the information receiving and processing unit; and the information receiving and processing unit is used for receiving the hardware version information of the information network unit and then driving and latching the hardware version information. The invention further discloses a corresponding method, comprising the steps of: providing the node information of each hardware version, constituting the hardware version information, receiving and driving the hardware version information and then latching the hardware version information. The whole identification process of the invention does not need human intervention, and is safe and reliable. When the hardware version information upgrades, only the welding of corresponding pull resistor needs to be changed, thus having convenient operation. The CPU transmits the hardware version information to a host computer unit, thus further realizing the derivative application on the aspects of BOOT rebooting, business software selection and loading, and software version configuration management, etc.

Description

technical field [0001] The invention relates to the field of hardware versions, in particular to a single board hardware version information identification method and system. Background technique [0002] Currently, general hardware includes a CPU, logic units, and various functional units. Due to the complexity of the design, the hardware changes variously, and more and more hardware version information needs to be identified, such as the printed circuit board (PCB, Printed circuit board) version, the bill of material (BOM, Bill of Material) version, the boot (BOOT) version, Electrically Programmable Logic Device (EPLD, Electrically Programmable Logic Device) version, Field Programmable Gate Array (FPGA, Field Programmable Gate Array) version, etc. How to clearly identify changes in different hardware version information, and enable users or application layers to accurately obtain current hardware version information is an important aspect to be considered in hardware desi...

Problems solved by technology

The shortcomings of this method are also obvious: the DIP switch needs to be manually toggled to the corresponding position to indicate the current board hardware version information. Due to manual participation, the risk of error increases; the DIP switch requires corresponding peripheral circuits, including power supply, One DIP switch can only manage one kind of board hardware version information, and multiple DIP switches are required to complete the relationship between multiple hardware version information. In this way, the management of the entire board hardware version information needs to occupy More PCB area brings difficulties to PCB board layout
