Embodiment Construction

[0039] In the field of embedded system debugging, the present invention mainly implements the execution and / or printing of real-time debugging commands, completes the output of user debugging commands, and has no special requirements for the realization of user commands themselves. In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below.

[0040] Starting from the perspective of terminal input command analysis, the present invention sets a preset symbol table in the embedded system in advance to record user commands and function instructions corresponding to the commands, and then parses the user's code in real time by looking up the table. Commands entered in the terminal. The real-time debugging and positioning method provided by the present invention has a specific process as follows:

[0041] The first step: query the user command input by the user through the termina...

Abstract

The invention discloses a method for debugging and positioning an embedded system in real time and a device thereof. The method comprises the following steps: A. querying a user command input by a user by a terminal; B. analyzing the user command and obtaining the corresponding function instruction by searching a prearranged symbol table; C. executing the function instruction; D. returning the prompting information concerning the result of execution to the terminal. The method and the device of the invention solve the problems in the real-time trace and debugging, and bring convenience to the application module of the embedded system for inputting a debug command and outputting debug information.

Description

technical field [0001] The invention relates to real-time debugging and print redirection processing technology in the field of embedded systems, in particular to a real-time debug and / or redirection implementation method and device thereof in an embedded system. Background technique [0002] In the communication system, the usual debugging method generally adopts TELNET (Telnet service is the earliest remote access service. It is in the early stage of network development, when all operating systems are still based on command mode control, in order to solve the problem of remote maintenance of the host computer, remote office A service specially developed for user needs, which has been used until now.) or other third-party tools such as SSH (the full English name of SSH is Secure Shell, by using SSH, any transmitted data can be encrypted, so that the "middleman" This kind of attack is impossible to realize, and it can also prevent DNS and IP spoofing; there is an additional ...
