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.

　　此外，在时间允许的情况下，建议大家看一下有关计算机操作系统工作原理以及计算机组成原理等方面的专业书籍。对于进程、线程、任务调度、总线、I/O等基本概念及工作原理有一个初步的了解和掌握，这部分知识的准备对于后续更好地学习嵌入式Linux系统开发将会起到很好的帮助作用。

　　3、嵌入式Linux开发

跟普通软件开发在学习方法上有什么不同?

　　要成为一名成功的嵌入式软件开发人员，程序的设计能力是首要技能，这一点与普通的软件开发人员的要求是一样的。但是作为“软硬兼施”的嵌入式开发，则要求大家不仅要了解较底层软件的工作过程和工作原理(例如操作系统级、驱动程序级软件)，在软件开发的专业水平上也需要充分考虑软件设计的时间和空间效率，这样才能设计出高性能嵌入式程序。
