How to start and deepen embedded system development and learning?

Many new users learn embedded systems, but do not know the knowledge and reference books in many directions. When I started, I lost my direction when I learned what to do first. Here is the answer you want to give you some advice.

This is the outline of the course I found on the ITjob training network. I think that as a learning step for embedded system development, I will implement and learn it step by step, it is a good learning method :) It is of great value even as a reference!

With the rapid development of information technology in modern society, embedded systems are widely used in military, household, industrial, commercial, office, medical, and other aspects of society, showing great investment value. From an international perspective, as the core of digital electronic information products, the current market for Embedded Systems in hardware and software development tools has exceeded 200 billion US dollars, the annual output value of the global industry brought about by the embedded system has reached 1 trillion US dollars. With the sustained growth of the global economy and the accelerated development of information technology, the embedded system market will inevitably grow further.

This course is designed to meet the rapidly developing embedded Linux requirements. The course aims to enable students to meet the basic qualities of embedded application software development, embedded system development, or embedded driver development. The course gradually leads you to the world of embedded development, using the most widely used software and hardware development platform Linux and Arm), to ensure that you are as close as possible to the current business needs.
