Problems solved by technology

When the board is abnormal, for example, when it cannot be turned on normally, the EEPROM cannot be read normally, and the log cannot be obtained, etc.
Maintenance and developers are unable to locate and analyze problems
At this time, you can only change the EEPROM to the normal board to read the content. This method has a great possibility of damaging the hardware board and is inconvenient to operate and maintain.

Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0016] like figure 1 In the topology, EEPROM is generally used to store configuration and status and related data files for IC and CPU. In this case, EEPROM is designed to be hung on CPLD, IC, and CPU devices through a two-choice switch.

[0017] In the X86 motherboard or ARM motherboard, CPLD is used as power-on and power-on sequence control, that is, as long as the board is powered on, CPLD will always work. Due to the characteristics of CPLD itself, its lif...

Abstract

The invention provides an EEPROM analysis system and method, the EEPROM analysis system comprises an EEPROM, an alternative channel, an IC, a CPU, a CPLD, a serial port, a key and an LED matrix; the EEPROM is respectively connected to the IC, the CPU and the CPLD through the alternative channel, and the CPLD is connected to the key, the serial port and the LED matrix. The EEPROM is mounted on a CPU through either-or access, and when an exception occurs, a maintainer controls the either-or access through a key to replace and mount the EEPROM on a CPLD; the CPLD is used as a core device for analyzing the EEPROM, internal data of each address bit of the EEPROM is scanned one by one, and the internal data is displayed through an LED matrix. The analysis scheme of the CPLD specifically comprises the following steps: reading related contents line by line for each address, then reading a value under an EEPROM address through an LED matrix, and displaying a specific value. The invention has the advantages that under the condition that the board card is abnormal, the EEPROM can still be analyzed, and data is provided for restoration.

Description

technical field [0001] The invention relates to an EEPROM analysis system and method, and belongs to the technical fields of hardware board design and logic monitoring. Background technique [0002] In X86 or ARM motherboards, many use EEPROM to save the important status, configuration and related data of the board. When the board is abnormal, such as the failure to boot normally, the EEPROM cannot be read normally, and the logs cannot be obtained. Maintenance and developers are unable to locate and analyze problems. At this time, you can only change the EEPROM to a normal board to read the content. This method may damage the hardware board and is inconvenient to operate and maintain. Contents of the invention [0003] The object of the present invention is to provide an EEPROM analysis system and method, and the EEPROM can still be analyzed if the board card is abnormal. [0004] In order to achieve the above object, the present invention is achieved through the follow...
