Single board read/writ system and method for information

Abstract

The present invention discloses a reading / writing system of single board information and method. The main control board of the invented system includes test control module, it is connected with CPU of main control board; the service board includes execution module connected with memory of the service board, said execution module is independent from CPU of service board or logic device; the described test control module is connected with the described execution module by means of interconnection line being in backboard. Besides, said invention also provides the concrete steps of implementing the invented method for reading / writing single board information.

Description

technical field [0001] The invention relates to the technical field of electronics or communication, in particular to a system and method for reading and writing information on a single board. Background technique [0002] The electronic label and manufacturing information of the board is a kind of data stored in the non-volatile memory on the board, which is used to record and identify the name, model, barcode, BOM (Bill of Material, bill of materials) code and description of the board, Key content such as production date, manufacturer, and manufacturing location can also include important content such as software / logic / hardware / structural information on the board, business configuration data, and board processing / maintenance records. [0003] The electronic label and manufacturing information of the board is one of the important data of the board. Its function is equivalent to the "ID card" of the board, and it is the only traceable symbol in the whole life cycle of the bo...

Problems solved by technology

[0018] It is not difficult to see that once the above four main components have any failure, especially the software failure in the CPU or logic device, the "single-board electronic label and manufacturing information" of the service board cannot be read and written correctly, so that the remote system or wireless In the application of human-attended systems, when a certain service board fails, it is not conducive to remote fault location and fault analysis

[0019] Therefore, the above technical solution has the disadvantages of unreliable read and write operations, and the inability to read and write correctly when the service board fails.

[0020] At the same time, the second shortcoming of the above-mentioned technical solution is that its implementation cost is relatively high, and its implementation cost includes:

[0021] 1. The hardware cost of the CPU or logic device on the service board;

[0022] 2. Software resources and operating costs of the CPU or logic devices on the service board;

[0023] 3. The hardware cost of the system "in-band bus" and its transceivers;

[0024] 4. Bandwidth cost of system "in-band bus" and transmission channel

[0025] Obviously, the above four costs make the cost of the system to realize the reading and writing functions of single-board electronic tags and manufacturing information relatively high
