Problems solved by technology

[0004] However, in the prior art, if the embedded device is powered off before the log information in the memory file system is compressed and written into the Flash file system, the log information in the memory file system will still be lost; If there are many log information, the embedded device still needs to write log information to the Flash file system multiple times, thereby reducing the service life of the Flash file system

Abstract

The invention provides a log management method and device. The method is applied to a terminal with an embedded system. A memory file system and a Flash file system are mounted in the embedded system. The method comprises the steps that log information of the embedded system is obtained; the working state of the embedded system is obtained; if the working state shows that the embedded system works normally, the log information is written to the memory file system; if the working state shows that the an exception occurs in the embedded system, the log information is written to the Flash file system. By means of the method, the log information which contains exception information occurring in the running process of an embedded device can be effectively stored and recorded, so that a user can position a fault, analyze causes of the exception and the like according to the log information, and meanwhile, the service life of the Flash file system is avoided from being affected.

Description

technical field [0001] The present application relates to the field of embedded technology, in particular to a log management method and device. Background technique [0002] With the development of computer technology, embedded system has become an important part of computer field. For embedded systems, the log information recorded during operation plays a very important role for users to locate faults. [0003] In the prior art, the embedded device can first write the log information generated in the running process into the memory file system, and then compress the log information in the memory file system and write it into the Flash file system to avoid The log information recorded in the memory file system is lost when the device is powered off. [0004] However, in the prior art, if the embedded device is powered off before the log information in the memory file system is compressed and written into the Flash file system, the log information in the memory file system...
