Log-dumping System with Multi-level Control Based on Linux Platform
Outline
一、Project Value
Various Bugs are always faced in embedded development. At this moment, we are firstly expected to find out the position and reason the Bug appeared so that we can modify the Bug more ter and faster. However, the position and reason of some Bugs with low reappearance rate are not easy to figure out. Here, in order to carry out reason positioning of such Bugs, it is necessary to add the confirmation of log print information in the place the problem may occur.
This system can provide other processes with the interface for log outputting, which support six log levels, wherein each level can control independently whether outputting or not, and using such interface, it can be set that outputting from the serial port, or dumping in hard disk for saving.
二、Main Content and Problem Solving
Offering interface for other software, and, according to the parameters like Level, Driver, Format provided by USER, processing and multi-levelly outputting onto the position client software. required.
三、Technology Means and Methods for Realization
Languages：c Language.
Development Environment：AM-Linux.
四、Achieved Results
The client software has such functions as setting the log levels, output position, output path, output file name, as well as showing the current mode, wherein each can be set in detail followed by carrying out controllable log-dumping with said settings.

A topic, meaning in development of embedded, often will meet various Bug, facing the Bug we need first to find the position and cause Bug appears to faster, ter modify Bug. However there are some reproduce rate is low bugs don't easily we find the position of the error and the reasons, and then to the reasons for such Bug positioning, need to be in place to add a problem can occur log printing information confirm, and these log information need to manage and keep. This system can provide other outputs the interface of the log, the output log interface support 6 a log level, each level can control alone whether output, use the output of the interface can set the log from the serial ports output or dump to hard disk file save. Second, the main content and solve problems for other software interface with, through the USER to provide Level (Level) position (Driver) Format (Format) parameters, such as processing output to the customer demand classification software position. Three, realized technology means and methods language: c. Development environment: AM-Linux. The results of the final four, to customer software but setting log level, output position, the output path, output filename and display the current pattern etc. Function. Each can conduct detailed Settings. Then through the setting of the log controllable dump.
