Multi-serial port switching system and method used for debugging server system

Abstract

The invention discloses a multi-serial port switching system and method used for debugging a server system. The system comprises a CPLD (Complex Programmable Logic Device) connected with each preset serial port of the server system, and a BMC (Block Multiplexer Channel) connected with the CPLD, wherein the CPLD is used for connecting external debugging equipment, and sending the input information of the debugging equipment to the BMC, and the BMC is used for controlling the CPLD to switch over to a corresponding serial port to be connected with the debugging equipment according to the input information of the debugging equipment. According to the system provided by the invention, optimizing for serial ports of a conventional system is performed on the basis of the CPLD and the BMC, external interfaces are reduced, all that is needed is to connect the debugging equipment to the CPLD, and automatic switchover to a corresponding serial port can be achieved according to needs, so that product debugging is achieved, development and debugging and later-stage maintenance for new products can be facilitated greatly, and the debugging efficiency in product development stage is improved.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a multi-channel serial port switching system and method for server system debugging. Background technique [0002] With the development of the electronic industry such as servers, more and more new products have been approved and developed. [0003] In the development stage of new products, in order to facilitate debugging in the development stage, it is usually necessary to connect some serial ports. At present, the commonly used method is to leave some serial ports outside the chassis, and leave some chip serial debug interfaces on the board. This makes the staff need to switch back and forth between different interfaces when debugging the single board. It takes a lot of time to find the debug serial port on the PCB. In addition, when the whole machine is tested, when there is a problem, the machine must be disassembled to access Dismantling the serial port of the internal re...

This makes the staff need to switch back and forth between different interfaces when debugging the single board. It takes a lot of time to find the debug serial port on the PCB. In addition, when the whole machine is tested, when there is a problem, the machine must be disassembled to access The serial port of the internal related chip, dismantling the machine will not only easily destroy the test environment, but also increase the workload
