Problems solved by technology

Therefore, for this situation where the SPD firmware needs to be changed many times, it is very inconvenient to use the method of burning the SPD firmware to EEPROM and then testing whether the SPD configuration parameters are feasible.

Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention will be further described in detail below in conjunction with specific embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] as attached figure 1 As shown, a memory SPD debugging method uploads the SPD firmware to be debugged to the BMC through the file upload function provided by the Web server of the BMC, and the BMC writes the firmware into the EEPROM through the I2C bus to improve the memory SPD debugging efficiency.

[0027] Its implementation process is:

[0028] 1. First, store the SPD as a file on the debugging host;

[0029] 2. Then log in to...

Abstract

The invention discloses a memory SPD debugging method. The implementation process of the memory SPD debugging method includes the steps of firstly storing an SPD as a file on a debugging host; then logging in a web management interface of a BMC, selecting a SPD firmware, and entering an update phase; leaving the debugging host in a shutdown state , using Standby voltage supply, accessing an EEPROMby the BMC, writing the firmware to the EEPROM; and booting a motherboard, and determining whether to further adjust the configuration of the memory SPD according to the system startup and operatingconditions. Compared with the prior art, the memory SPD debugging method uses the out-of-band management function of the BMC to debug the memory SPD through on-line refresh operation on the SPD firmware, is simple and effective, can greatly save costs and has strong practicability, wide range of applications and easy popularization.

Description

technical field [0001] The invention relates to the technical field of computer servers, in particular to a memory SPD debugging method. Background technique [0002] A BMC (Baseboard Management Controller) is often placed on the main board of the server. The BMC provides I2C and other interfaces to access external devices. Through the management network of the BMC, the out-of-band management of the server can be performed when the host is not powered on and the business network is inaccessible. [0003] For ruggedized servers, the memory is often surface-mounted in the form of memory particles to improve stability and reliability. Since surface-mounted memory chips are different from standardized memory sticks produced by memory stick manufacturers, server manufacturers need to design dedicated SPD (Serial Presence Detect) configuration parameters according to the memory parameter configuration specifications and the PCB characteristics of the main board. It is reasonable ...
