Abstract

The invention relates to a network concentrated debugging method for embedded system software. The method comprises the following steps of: on a server part, establishing a file folder, serving as a special catalog for storing running logs of an embedded terminal, on a system disk; adding the new file folder into network sharing to provide a space for storing the running logs of the embedded terminal; establishing a new system user name so that the embedded terminal logs in the server by using the identity of the user; and opening a reading-writing authority to the new user for debugging the shared file folder; and on an embedded terminal part, adding a network sharing scheme matched with a file sharing protocol of a debugging server; accessing the shared and debugged file folder of the debugging server through a network sharing protocol; establishing a log file with a special name in the shared file folder; opening the log file and writing the debugging information into the file during running; and closing the file and cutting off a sharing link when the embedded system is abnormal. By the method, the tracking and the debugging of the embedded terminal system in a normal working state can be realized.

Description

A kind of network of built-in system software is concentrated adjustment method

[technical field]

The present invention relates to a kind of adjustment method of built-in system software, be applicable to computer realm, particularly have a plurality of built-in terminal centralized management systems of network interconnection ability.

[background technology]

Embedded system is normally towards application-specific, and itself does not possess ability to develop independently, and the system resource redundance is less.Since these characteristics of embedded system, the adjustment method commonly used in the PC systems development process, as: running log, single step tracking, debugging acid etc. are difficult to its effect of performance in embedded system.

At present, the debugging of embedded system mainly contains two kinds of methods:

1, obtains Debugging message by reserving the hardware debug mouth: owing to need to reserve hardware interface, and need special-purpose debugging acid trace debug information, this method often is confined in the laboratory or the research and development of products stage, and needs the developer to carry out field adjustable when problem occurs;

2, telecommunication network debugging: this method needs system to be under the experimental state, can't follow the tracks of the error message that product produces under normal operating condition, often be confined to the internal debugging stage, for release product occur unusual, need be on debug machine the reproduction problem to obtain unusual field adjustable information, for more obscure unusual, this process may spend a large amount of time.

The adjustment method of existing embedded system system software all has two bigger restraining factors: Debugging message must on-the-spotly in real time be followed the tracks of, system must be in abnormal operating state.

[summary of the invention]

Technical matters to be solved by this invention is to provide a kind of efficient height, built-in system software network that cost is low to concentrate adjustment method, this method can realize built-in terminal system trace debug in normal operation, and Debugging message is checked when system exception for the developer when preserving terminal operating by the mode of running log, has solved two the restriction problems of current adjustment method on system running state and information obtain manner simultaneously.

The present invention solves the problems of the technologies described above by the following technical solutions:

A kind of network of built-in system software is concentrated adjustment method, comprises the steps:

Step 10: server section: specifically comprise the steps:

Step 11: on system disk, set up file, as preserving built-in terminal running log private directory;

Step 12: add newly-established file to network and share, provide the space for preserving the built-in terminal running log;

Step 13: set up new system user name, and password is set, built-in terminal uses this user identity logon server;

Step 14: be the access limit of new user's commissioning Shared Folders, make the addressable this document folder of built-in terminal;

Step 20: built-in terminal part: specifically comprise the steps:

Step 21: increase the network shared scheme realization supporting with the debugging server file sharing protocol;

Step 22: share the protocol access debugging server by network and share the debugging file folder;

Step 23: the journal file of under Shared Folders, setting up proprietary name;

Step 24: open journal file, Debugging message writes this document in the time of will moving;

Step 25: this document appears closing when unusual in embedded system, and disconnects and share link.

The invention has the advantages that: this method can realize built-in terminal system trace debug in normal operation, and Debugging message is checked when system exception for the developer when preserving terminal operating by the mode of running log, has solved two the restriction problems of current adjustment method on system running state and information obtain manner simultaneously.The debugging that can be applicable to have the concentrating type built-in terminal software of network inter-transmission function is followed the tracks of.Use this adjustment method, can solve existing adjustment method must real-time follow-up, system must be in these two major defects of abnormal operating state, has reduced the human cost of system failure eliminating work on largely, improves fault removal efficiency, accelerate development progress, improve customer satisfaction.
