Linux technology learning points, have you mastered it - a must-see for beginners

　1. How to prepare for embedded Linux learning?

　　To become a qualified embedded Linux engineer, you need to systematically learn knowledge in software and hardware related fields, and you need to master the development norms and principles at the very beginning. Develop good work habits. In order to ensure the effect of learning, the whole course system arranged by Xinyingda is very concentrated and efficient, which requires students who are going to participate in the embedded Linux employment course to adjust their time, and make sure to make sure that they are within 4 months. Ability to concentrate highly during study time. Brothers even Linux training

.

　　During the entire intensive learning process, it is necessary not only to ensure the time for careful listening and practical exercises in class, but also to ensure the time to continue practical exercises and review materials after class. Only after this high-intensity, practical-oriented training can you master the standardized embedded development workflow in a relatively short period of time, so that you can meet the needs of the corresponding positions in embedded enterprises.

　　In addition to being fully prepared in terms of study time, you must also be prepared in terms of the adjustment of your learning attitude and methods. Many friends only understand the bright development prospects of embedded Linux, and only pay attention to hot spots such as high income and more employment opportunities, but ignore the learning process itself. In order to make the best effect of centralized training, it is recommended that you learn more about the characteristics of embedded product development, the technical specifications and work points that need to be mastered before starting the learning, and pay attention to the basic supplement and learning, so as to Prepare mentally for the follow-up reinforcement learning process. After all, attitude often determines the final result of doing things.

　　2. What basic courses do I need to take to learn embedded Linux?

　　Embedded Linux engineers need to have a certain C language foundation, so many friends have only learned C in their freshman or sophomore year (not necessarily serious, huh, huh) !), after that, it is basically no longer used. It is recommended that you review the basics of C language first. It should be reminded that you should not only focus on the basic grammar when reviewing, but also pay attention to commonly used data storage and processing methods, such as: arrays, structures, etc. If you have the conditions, you must type the code on the machine, analyze and understand the details. The idea of ​​​​writing the case code, let yourself slowly enter the state of an embedded developer.

　　In addition, if time permits, it is recommended that you read professional books on the working principles of computer operating systems and the principles of computer composition. Have a preliminary understanding and mastery of basic concepts and working principles such as process, thread, task scheduling, bus, I/O, etc. The preparation of this part of knowledge will play a good role in better learning embedded Linux system development in the future. help.

　　3. What is the difference between embedded Linux development

and ordinary software development in learning methods?

　　To become a successful embedded software developer, program design ability is the primary skill, which is the same as the requirements of ordinary software developers of. However, as a "software and hard" embedded development, it requires everyone not only to understand the working process and working principle of the lower-level software (such as operating system-level, driver-level software), but also to fully consider software design at the professional level of software development. time and space efficiency, so that high-performance embedded programs can be designed.
