Nowadays, many online education platforms and social media provide a large number of embedded Linux learning resources, such as course videos, technical blogs, open source projects and so on. You can search related training courses through these platforms, and then study according to your own needs and schedule. Some well-known online education platforms also have free learning courses, through which you can learn the basic knowledge and skills of embedded Linux.
Of course, free learning is just a way of learning, which can help you understand some basic knowledge and methods, but it lacks systematicness and depth. If you want to learn embedded Linux deeply, it is recommended to choose some professional training courses or participate in offline training institutions. Although these training courses may cost some money, the systematic and in-depth learning they provide can help you master knowledge and skills better, and you can get more guidance and support during the learning process.
In a word, it is feasible to learn embedded Linux for free, but it requires a certain foundation and self-learning ability. If you want to study embedded Linux deeply, it is recommended to choose professional training courses or participate in offline training institutions. At the same time, we need to pay attention to the authenticity and reliability of information and avoid the interference of false information and bad resources.
