Embodiment
The present invention provides a kind of method that long-range Debug is carried out using BMC, at BMC and the CPU/PCH end of server master board
Between set up logic circuit, BMC is connected one to one master signal and CPU/PCH ends by logic circuit, further according to situation
BMC and the master signal transmission direction at CPU/PCH ends are controlled by logic circuit, make master signal flow direction correct, realization pair
CPU/PCH carries out long-range debug.
A kind of logic circuit is provided simultaneously, is arranged between BMC the and CPU/PCH ends of server master board, BMC is by patrolling
Collect circuit master signal and CPU/PCH ends connect one to one, passing through logic circuit further according to situation controls BMC and CPU/
The master signal transmission direction at PCH ends, make master signal flow direction correct, realize and long-range debug is carried out to CPU/PCH.
For the object, technical solutions and advantages of the present invention are more clearly understood, below in conjunction with specific embodiment, to this hair
Bright further description.
Using the inventive method, logic circuit is set up between BMC the and CPU/PCH ends of server master board, BMC is by patrolling
Collect circuit master signal and CPU/PCH ends connect one to one, wherein BMC generally has TCK/TMS/TDI/TDO/TRST etc. main
Signal is controlled, TCK/TDO/TRST/TMS signals are that master control sends signal, i.e. BMC is sent to CPU/PCH ends, and TDI receives for master control
Signal, the flow direction of two kinds of signals is different,
BMC and the master signal at CPU/PCH ends is according to circumstances controlled to transmit by the level conversion circuit inside logic circuit again
Direction, wherein BMC chip operating voltage are 3.3V, and CPU/PCH operating voltages are 1.05V, and both level mismatch, level conversion
Circuit realizes the flow direction difference according to two kinds of master signals using voltage conversion chip, and adjustment master signal flows to correct；
MAC built in BMC combines with onboard PHY chip carries out remote management, realizes that BMC can be configured to using BMC is remotely accessed
Master patterns, realize and long-range debug is carried out to CPU/PCH.
The above-mentioned output when it is implemented, the voltage conversion chip that level conversion circuit utilizes can be opened a way by drain electrode,
Pull-up resistor can be added in the input/output terminal of voltage conversion chip, prevent that line level is abnormal, influence normal function.
And working as above-mentioned server master board includes XDP connectors, it is connected with CPU/PCH ends, can be by logic circuit
Gating switch circuit is also connected with BMC, gating switch circuit include data strobe chip and its connection with door；
To avoid ITP instruments and BMC in XDP modes while being used as master control, while reduce the signal quality that signal wire diverging band comes
Influence, increase gating switch circuit selects to visit CPU/PCH ends according to the master mode for carrying out debug in logic circuit
The link asked：
When ITP instruments insert XDP interfaces, XDP signals in place can be set to 0 automatically, i.e. low level, with door after 0 electric potential signal is received,
Logic low is exported to close the data transmission link between BMC and CPU/PCH, and data receiver link can not be handled, this
When CPU/PCH is conducted interviews only XDP/ITP circuits；
And when XDP is not inserted into, then XDP signal acquiescences in place are set to 1, i.e. high level, are completely controlled by with the output state of door
BMC Select pins, when this pin is arranged to 1, high level logic is exported with door, BMC circuits are opened, and BMC can be right
CPU/PCH ends conduct interviews, and due to now not external ITP instruments of XDP, cabling is shorter, and influence caused by signal bifurcated can be neglected.
In above-mentioned specific implementation, BMC, logic circuit, XDPS and CPU/PCH ends are connected using jtag bus, and then
Access CPU/PCH internal datas, register value, the highly dense connectors of 60 Pin that it can be standard that wherein XDP, which is, level conversion line
Road can utilize the GTL2014 chips of NXP companies, and data strobe chip can use the SN74CBTLV3126DR of TI companies, and BMC can
The AST2500 chips of ASPEED companies are selected, PHY chip can use the RTL8211FD, CPU/PCH Intel of Marvel companies
Corresponding platform chip.
