Embodiment Construction

[0036] The method of the present invention is described in detail below.

[0037] The present invention opens up a stack trace record area for each stack in the reserved memory of the single board, and the circular queue in the stack trace record area records the functions and printed information recently executed in this stack, so as to give the debugger a clear message The processing flow can save a lot of debugging time; when the stack is completely destroyed, the usual debugging means cannot display the function call process, and the function call process can also be displayed through the stack trace record area; the present invention can also be used when the program runs away In the case of reset, by powering on again, observe the stack trace recording area information of the last operation in the memory reserved by the board, and quickly locate the running function.

[0038] Implementation of the present invention is divided into 4 major parts:

[0039] 1. When powerin...

Abstract

The method includes steps: setting up at least one stack trace record area on memory for each stack, and initializing the area; executing printing information recording function, in printing procedure, calling printing contents saving function to save printing information to the said trace record area; executing a entrance trace record function at entrance; executing a exit trace record function at exit, embedding stubs at entrance and exit of functions in application program; calling analysis debugging function in use for stack trace record area to display all basic information in the stack trace record area, as well as procedures of function call and saved printing contents. The invention does not inference on task dispatching procedure of software to be tested, analyzes abnormity of software by using information recorded in stack trace record area without need of hardware analysis.

Description

technical field [0001] The invention relates to a method for multi-task concurrent debugging of an embedded system in the communication field. Background technique [0002] In the software developed on the embedded operating system, such as communication software, a large number of state machine processing mechanisms are used. The traditional debugging method can be summarized as the following process: set a breakpoint--program pause--observe the program state--continue to run. However, the traditional method of setting breakpoints for debugging is time-consuming and laborious. If you want to check whether a message has arrived, you need to set a breakpoint in the message processing function and wait for the message to arrive. When the message arrives, the program stops and then single-step tracking , and observe whether it is consistent with the design. Moreover, after the breakpoint is stopped, due to the concurrency of the multi-tasking system, the environment after the ...
