Abstract

The invention provides a method for debugging a log in an embedded system process. The method comprises the following steps: integrating a log calling function to form a library function which can be called by various processes; initializing a log grade, a log destination and a process identification of the process; defining a log grade debugging function to add the debugging information of different log grades; adding an interface for receiving the setting information of the process log grade and the log destination; adding an order interface for setting the process debugging grade and a debugging information output destination; outputting a debugging log printing record. By adopting the method, the debugging function of the system is unified, the debugging printing of various modules and various styles of different programmers can be avoided, and the research and development and test working efficiencies and the later system maintenance efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method for debugging logs in embedded system processes. Background technique [0002] In the field of embedded or software development, debugging is a very important link. Ease of debugging code is extremely important. Therefore, if the debugging method of a good system is more convenient, it can greatly improve the development efficiency. [0003] Unlike the rich variety of traditional desktop software development and debugging tools, the debugging of embedded systems is not very convenient due to the shortage of system resources, and there is also a lack of professional debugging tools. Therefore, the debugging efficiency of the embedded system is relatively low at present. [0004] In the prior art, the most commonly used debugging methods for embedded systems mainly include the following three types: [0005] (1) Add printf printing function in the place to be ...
