Embodiment Construction

[0022] In order to make the purpose, characteristics and advantages of the technical solution of the present invention clearer, the present invention will be described in detail below by taking single-board software as an example.

[0023] The memory used by the board software is generally allocated by the system according to the needs. The memory used by a typical board software is divided into a reserved area, a management memory area, an application program storage area, a patch storage area, and a free area, as shown in Figure 1. Show. The space size of each storage area is allocated according to specific conditions, or through dynamic allocation.

[0024] Because the software is running (including initialization), if the variable or memory cannot be initialized correctly, the value in the variable or memory may be a random value, resulting in unpredictable system output. Due to the randomness of the problem, the code where the problem occurs and the initialization code t...

Abstract

The present invention discloses a method for locating software fault. Said method includes the following steps: (a), in internal memory prereserving a zone for storing information related to the system operation state; (b), in the course of system operation recording the current newest related information and storing said current newest related information and storing said current newest related information in the described prereserved zone; (c), in the initialization process when the software is again started after fault reserving the information stored in the described prereserved zone; and (d), fetching and analyzing the described information stored in the prereserved zone and reproducing instantaneous system state before fault.

Description

technical field [0001] The invention relates to the field of computer and information technology, in particular to a method for locating software faults. technical background [0002] With the development of network communication technology, the functions of system equipment are becoming more and more powerful, which makes the system program tend to be large and complex. Therefore, during the operation of the system, some abnormal situations often occur, sometimes causing the system or functional unit (single board) reset. But locating the fault that caused the abnormal condition is more complicated. For example, using a real-time operating system, set a breakpoint in the program to track the running of the program. Every time the program is executed to a breakpoint, the state of the program, the status of the stack, the contents of each register, and the variables set by the user can be obtained to locate the fault. , this method is very effective in the process of progra...
