Problems solved by technology
[0003] In the COMe specification, there is only one set of SPI (Serial Peripheral Interface, Serial Peripheral Interface) signals defined on the backplane connector. ) FLASH chip redundancy backup signal channel, but it can only realize the switching of the CPU from the main BIOS or the slave BIOS, and cannot realize the BMC (Baseboard Management Controller, baseboard management controller) to upgrade and maintain the master BIOS and the slave BIOS image at the same time. The out-of-band management function is limited, and the switching method is not automatic, which is very inflexible

The invention discloses a double-BIOS (Basic Input Output System) monitoring system of a COMe board card. The monitoring system comprises a first switch device, a second switch device, a first CPLD (Complex Programmable Logic Device) arranged on a Module, and a second CPLD arranged on a Carrier, wherein the first switch device is respectively connected with the CPU, the COMe connector and the mainBIOS, and the second switch device is respectively connected with the BMC, the COMe connector and the slave BIOS. According to the monitoring system, automatic switching of BIOS starting of the CPU or upgrading link switching of the BMC to the two BIOS can be completed, the BMC can conduct out-of-band management on the main BIOS mirror image and the auxiliary BIOS mirror image at the same time, control is flexible, management is convenient, and system reliability is improved.
Description
technical field [0001] The application relates to the field of computer circuit system design, in particular to a dual BIOS monitoring system for COMe boards. Background technique [0002] As an industry standard, COMe specifies a board form of onboard computer, which integrates the core components of the computer system such as CPU (Central Processing Unit, central processing unit) and memory on the module (Module). The boards (Carriers) are interconnected through backplane connectors, and the specification also defines the format, quantity, and level of signals on the backplane connectors. With its characteristics of decoupling the core components of the computer system from the functional modules, COMe provides an effective solution for the modular reuse of computer products, accelerates the product iteration speed, and is widely used in embedded computers, industrial computers and other fields . [0003] In the COMe specification, there is only one set of SPI (Serial P...
