An embedded system core dump method

Abstract

The invention belongs to the technical field of computer system software specialty. Based on an embedded development environment, by use of a software structure which is configured by a host end and achieved on a target machine end, acquisition of system memory and program information is supported according to a core dump type, corresponding core dump information is generated and stored, and the problems of error field capture, error information storage, error analysis difficulty and the like of an embedded system are better solved. According to the invention, the graphical configuration of the system is supported, and the graphical configuration interface is provided at the host end, so that the usability and the intuitiveness of the core dump configuration are improved; Core dump information is supported to be acquired from an operating system and specifically comprises a memory, a register state, a stack state, memory management information and various function call stack information during program running, so that the reliability and integrity of acquiring the core dump information are improved; Storage of the output core dump information is supported, the safety of the core dump information is improved, and then the error positioning and troubleshooting efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of computer system software, and relates to a method for core dumping of an embedded system. Background technique [0002] With the rapid development of embedded operating systems, various platforms based on embedded operating systems have been widely used in important fields such as aerospace, industrial control, and communication satellites. At this time, the security and reliability requirements of the embedded operating system are getting higher and higher with the expansion of its application scale. In embedded devices, the memory space that the system can use is often very limited, so the programmer needs to make a fine allocation of the memory space of the embedded system to ensure the security of memory access. But even so, some unpredictable errors will still occur during the running of the program. When the core process of the system generates an error that cannot be recovered, in order to avoid g...
