� To understand the Linux system deeply.<br />

� To understand the rel<strong>at</strong>ionship between hardware and software.<br />

� To have p<strong>at</strong>ience for solving of problem.<br />

� An accur<strong>at</strong>e analysis of problem.<br />

� Using a debugger<br />

When a problem occurs during developing, a developer must be done quickly by<br />

using a debugger. If one is skillful with a debugger program, it is possible to do the<br />

debugging quickly.<br />

� Approach for problem solving<br />

To understand the problem of complic<strong>at</strong>ed embedded systems, it is better to start<br />

analyzing when driver or applic<strong>at</strong>ion is minimized and gradually approaching to<br />

problem than analyzing while numerous service programs, such as applic<strong>at</strong>ion,<br />

device driver, are running It is undoubted story. To do debugging process in large<br />

OS, it is easy to look into the problem by analyzing fractionally.<br />

We have mentioned various methods for debugging. A skillful developer will know above<br />

methods very well. However, not every developer is skillful and it is possible for the<br />

developer with many experiences to spend long time solving the problem if the problem is<br />

very complic<strong>at</strong>ed. Therefore, DL is a step th<strong>at</strong> check the problem in a system and if a
