Problems solved by technology

However, limited by the hardware resources of the embedded system, the random access memory (random access memory, RAM) or flash memory (Flash EEPROM Memory, Flash) used for storage is very valuable, and these memories not only need to be used for the running memory of the embedded system , but also to store some important configuration files, so there is very little memory available for logging

Abstract

The embodiment of the invention discloses an embedded system log recording method and device. According to the method, a total number of files and an upper limit of a file size set by a user are received; generated log information is stored into a target file, and if the target file does not exist, the target file is established first; and when the memory size of the target file exceeds the upper limit, the target file is renamed, and a target file with the original file name is reestablished and used for recording newly generated log information. When the number of all established log files exceeds the total number, one log file not conforming to a preset condition is deleted, all the remaining log files and the target file are renamed according to preset naming rules, and a target file is created again. Logs are recorded in a rolling mode, that is, when the log recording size reaches the upper limit, newly recorded logs will cover oldest logs, and therefore the purposes of increasing the memory utilization rate and prolonging log recording time are achieved.

Description

technical field [0001] The invention relates to the technical field of embedded systems, in particular to a method and device for logging records in an embedded system. Background technique [0002] In today's society, embedded systems are more and more widely used in various industries, ranging from aerospace equipment to microwave smart watches, all of which have embedded programs running in them. Due to the particularity of the embedded system operating environment, it is difficult to locate and debug problems. At this time, log (log) records are particularly important for problem location and debugging. However, limited by the hardware resources of the embedded system, the random access memory (random access memory, RAM) or flash memory (Flash EEPROM Memory, Flash) used for storage is very valuable, and these memories not only need to be used for the running memory of the embedded system , but also to store some important configuration files, so there is very little me...
