Implementation method for debugging information output in embedded system

Abstract

The invention relates to an implementation method for debugging information output in an embedded system, comprising the following steps: a screening tool screens an engineering source code to generate the corresponding relation of debugging positioning information and debugging information; when the embedded system operates the engineering source code and needs to output the real-time debugging information, output information with the debugging positioning information is transmitted to debugging control output equipment; the debugging control output equipment obtains the debugging positioning information and finds the debugging information according to the corresponding relation of the debugging positioning information and the debugging information; and the debugging control output equipment displays the debugging information. The implementation method for debugging information input in the embedded system greatly reduces the system expenditure of a debugging output module of the embedded system and saves bandwidth occupied by the debugging information data on a universal serial bus to bring convenience for the transmission of other data. The method has simple and convenient process, stable and reliable working performance and wide applicable range, thus bringing great convenience for debugging the embedded system.

Description

technical field [0001] The invention relates to the field of embedded systems, in particular to the technical field of debugging of embedded systems, in particular to a method for realizing debugging information output in an embedded system. Background technique [0002] Debugging and testing of embedded system (microsystem) is a very important part of embedded system design. Efficiently obtaining various information when the embedded system is running is the basis of debugging and testing, and it is also the place that should be paid attention to at the beginning of system design. A good debugging information output method can effectively reduce the proportion of the debugging information output module in the resource consumption of the entire microsystem, and give other functional modules more space to play. [0003] The so-called debug information (signpost) of the embedded system refers to the output and print information through function calls in the source code of the...

Problems solved by technology

[0006] (1) The operating object of the debugging information output module of the microsystem is the text to be displayed. If the amount of output information is large, the debugging information output module itself will occupy a lot of system resources (such as CPU time and memory space), which will affect other The normal operation of some functional modules has a certain impact. In extreme cases, other functional modules cannot work normally.

[0007] (2) The data flow of a large amount of debugging information will occupy a large bandwidth of the serial bus, which is not conducive to the transmission of other data on the serial bus between the microsystem and the PC

[0008] The above problems are rooted in the fact that the transmission data is not compressed during the output of the debugging information, so the data volume is relatively large and the efficiency is very low, which brings certain obstacles to the debugging of the embedded system and also affects The operating efficiency of embedded systems has also brought great inconvenience to people's work
