Embodiment

[0025] see figure 1 , to modify the flow chart for the software code of the embedded system, the specific process is described as follows.

[0026] First, determine whether it is necessary to record information at system startup. If so, add the code for writing the startup information into the storage medium in the startup function, and then continue to browse the subsequent codes. Otherwise, browse the subsequent code directly.

[0027] Then judge whether the work of all stages has been completed. If yes, it is judged whether it is necessary to record the system exit information. Otherwise, it is necessary to determine whether a particular stage of work has been completed. If so, continue to judge whether it is necessary to record the information that this stage has been completed, otherwise continue to browse the subsequent code. If it is necessary to record the completed information of this stage, add the code for writing the completed information into the storage medi...

Abstract

The invention discloses a method capable of recording an operational process of an embedded system, and the method is characterized in that for software in the embedded system, a code capable for writing recording information into a storage medium is added in a code for starting and normally stopping the software; the code for writing the information which is already completed at the stage into the storage medium at any operational stage of the software can be added according to the requirements; and the abnormally withdrawing information is written into the storage medium through the actuation of a power failure interruption function before the system is stopped abnormally because of the power failure. The method is convenient for the system design and development personnel to analyze an operational state of the system, debugging and troubleshooting can be carried out for the system, and the maintainability of the system can be improved.

Description

technical field [0001] The invention belongs to the technical scope of software development, more specifically a method capable of recording the running process of an embedded system. Background technique [0002] Compared with general computers, embedded systems are mainly used for the processing of specific tasks, and are widely used in aviation, aerospace, industrial control, digital information appliances and other fields. In our daily life, we have been able to access more and more, such as mobile phones, TVs, washing machines, refrigerators, rice cookers, air conditioners, cars, digital cameras, etc., all contain various embedded systems. [0003] For more complex embedded systems, once a fault occurs, if there is no relevant operation record, it is often difficult to locate the cause of the fault, resulting in failure to solve the fault smoothly. Therefore, it is a relatively important feature to be able to record the running process of the embedded system during its...
