Method for debugging embedded software and application system thereof

Abstract

The invention discloses a method for debugging embedded software and an application system thereof. The method comprises the following steps: a client end queries an operation maintenance module for establishing the TCP connection and sends a registration authentication message, the operation maintenance module carries out the authentication and returns the reply to the client end, the current debugging level is confirmed, simultaneously, the TCP connection to a target single board is established, and the information of the debugging level is sent to the target single board; according to the level information, the target single board returns all the debugging instruction lists currently supported to the module and to the client end; the client end saves the received lists, prompts a user that a debugging channel between the client end and the single board is established; the client end receives and sends the input debugging instructions, the debugging instructions are received by a target single board debugging proxy by the channel, and according to the content of the instructions, the debugging action is executed and the result is researched, and the result is returned to the client end by the channel, and the client end displays the received result from the debugging channel. The method and the application system of the invention overcome the shortcoming that a plurality of target single boards cannot be switched during the debug of the system and solve the existing problem that the debugging instructions cannot distinguish the debugging level.

Description

technical field [0001] The invention relates to an embedded software debugging technology, in particular to an embedded software debugging environment for multi-client and multi-target single boards. Background technique [0002] The communication system is widely implemented based on embedded system technology, which has the characteristics of strong pertinence, high reliability and low cost. But because of its specific architecture, debugging means are limited. The current debugging method is generally that the user connects to a specific embedded system through a serial port or Telnet, inputs debugging commands, and observes the results printed on the screen. If there are multiple single boards in a certain system, the connection needs to be switched multiple times. [0003] In addition, the current debugging methods generally do not distinguish the debugging level of user input commands. Users can input any debugging commands, such as single board reset and other comma...

Problems solved by technology

[0004] The technical problem solved by the present invention is to provide a method for debugging embedded software and its application system, to overcome the shortcomings of the existing embedded software system debugging technology that cannot flexibly switch multiple target single boards for debugging, and to solve the problems of the prior art There is a problem that the debugging instructions cannot distinguish the debugging level, which may lead to serious consequences
