The core of the present invention is to provide a kind of multi-channel serial port switched system for server system debugging and method, permissible
Improve the debugging efficiency of product development stage.
In order that the above objects, features and advantages of the present invention can become apparent from understandable, below in conjunction with the accompanying drawings to this
Bright specific embodiment is described in detail.
Elaborate detail in order to fully understand the present invention in the following description.But the present invention can with multiple not
It is same as alternate manner described here to implement, those skilled in the art can do class without prejudice in the case of intension of the present invention
Like popularization.Therefore the present invention is not embodied as being limited by following public.
Refer to Fig. 1, the multichannel for server system debugging that Fig. 1 is provided by a kind of specific embodiment of the present invention
Serial ports switched system structural representation.
A kind of specific embodiment of the present invention provides a kind of switching of the multi-channel serial port for server system debugging system
System, comprising:
The cpld being connected with each default serial ports of server system, the bmc being connected with cpld, wherein, cpld is used for connecting
External debugging device, and the input information of commissioning device is sent to bmc, bmc is used for the input information control according to commissioning device
Cpld processed is switched corresponding serial ports and is attached with commissioning device.
In the present embodiment, as shown in figure 1, with the equipment in server system include pch, device0, device1,
Illustrate as a example device2, device3.Cpld1 is connected with the uart of bmc2, and cpld1 and device0, device1,
The uart of this four equipment of device2, device3 connects, and in the present embodiment, external commissioning device preferably passes through logical
Communication interface rs232 and cpld1 is attached.Preferably, it is additionally provided with a road i2c between bmc and cpld, wherein, bmc passes through itself
Uart receiving unit rx real-time reception cpld send signal, wherein, be provided with the depositor of predetermined number in cpld1, post
Each value of storage is corresponded with each default serial ports, and depositor is used for changing the value of itself according to the control signal that bmc sends,
The currency that cpld is used for according to depositor is switched corresponding serial ports and is attached with commissioning device.Bmc sets according to the debugging receiving
Standby input information, and control the cpld corresponding serial ports of switching to be attached with commissioning device by i2c.
Further, in the present embodiment, so that the depositor of a 8bit is set in the cpld as a example switching to serial ports
Illustrate.First, define the depositor of a 8bit in cpld, the initial value defining this depositor is xxxx0000, its
In, cpld according to initial value give tacit consent to by the uart of pch be connected to outside commissioning device (wherein, the Gao Siwei of depositor according to
The quantity of serial ports uses, and wouldn't use in the present embodiment), the special string that some are of little use, such as % $ can be defined
00th, % $ 01, % $ 02, % $ 03, % $ 04 etc., the input information of commissioning device comprises a certain special string therein, works as bmc
The value of depositor when receiving this special string, is changed by i2c.Wherein, each special string and depositor are pre-defined
The corresponding relation of value and the value of depositor and corresponding device serial ports relation, that is, corresponding one of special string post
The value of storage, the serial ports of the corresponding equipment of value of a depositor.As bmc receives % $ 01, then deposited by i2c modification
The value of device is switched to the uart of the first equipment for 0001, cpld according to the value of depositor, and the first equipment here corresponds to
device0；Bmc receives % $ 02, then be switched to according to the value of depositor for 0010, cpld by the value that i2c changes depositor
The uart of the second equipment, the second equipment here corresponds to device1；Bmc receives % $ 03, then change depositor by i2c
It is worth the uart being switched to the 3rd equipment for 0011, cpld according to the value of depositor, the 3rd equipment here corresponds to device2；bmc
Receive % $ 04, then the 4th equipment is switched to for 0100, cpld according to the value of depositor by the value that i2c changes depositor
Uart, the 4th equipment here corresponds to device3.Certainly with the increase of equipment, corresponding serial ports can be carried out in advance and post
The value of storage and the corresponding definition of special string.So, the depositor of 4bit just can realize the serial ports of 16 equipment
Switching output, can be extended, according to actual needs thus all of serial ports realizing server system can be accessed
Arrive.
It should be noted that so-called cpld refers to CPLD, bmc refers to substrate management and controls
Device, i2c refers to twin wire parallel bus, and uart refers to universal asynchronous receiving-transmitting transmitter.
The multi-channel serial port switched system for server system debugging in embodiment of the present invention, reduces external interface,
Only commissioning device need to be connected on cpld it is possible to automatically switch to corresponding serial ports as needed, thus realizing product is entered
Row debugging, is very easy to the exploitation debugging for new product and later maintenance, improves the debugging effect of product development stage
Rate.
Refer to Fig. 2, the multichannel for server system debugging that Fig. 2 is provided by a kind of specific embodiment of the present invention
Serial ports changing method flow chart.
Correspondingly, one embodiment of the present invention additionally provides a kind of switching of the multi-channel serial port for server system debugging
Method, comprising:
S11: obtain the first input signal of server system external debugging device.
