Abstract

The invention discloses a method and device for viewing code information in system abnormality. The method comprises the following steps of: setting a reserved memory area in a physical memory, wherein the reserved memory area is not used and allocated by a system and comprises a real-time recording area and a backup recording area; recording code information in the real-time recording area in real time when the system is in operation; and when the system is in abnormality and is restarted, copying the code information of the real-time recording area to the backup recording area, and viewing the code information when the system is in abnormality through acquiring the code information in the backup recording area. According to the method, the code information is recorded in real time when the system is in operation, the code information which is recorded in real time is copied to the backup recording area for viewing when the system is in abnormality and is restarted, and then, the site code information in system failure is obtained, and a basis is provided for an analyst to analyze the system failure and contributes to the quick solution of the failure.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for viewing code information when a system is abnormal. Background technique [0002] System software failure has always been one of the main failures in the field of communication technology. When the system software fails, developers often need to analyze the code information before the system error to determine the cause of the failure. Therefore, obtaining the code information before the system error becomes one of the very important steps. [0003] For embedded devices, for example, embedded gateways; limited by the limited resources of embedded gateway devices, it is difficult to transplant some powerful debugging tools, such as GDB and other tools, to embedded devices. Moreover, many codes are optimized by the compiler so that the program size can be reduced as much as possible. The result of optimization makes it difficult to diagnose the soft...
