Linux System Programming and Buildroot Fundamentals

To develop software for embedded devices or deep system-level applications, you must understand how to interact directly with the operating system kernel and C libraries. This text-based course guides you from foundational system concepts to building your own custom, minimal embedded Linux distributions. You will gain a clear grasp of how user-space applications communicate with the kernel and how to compile a tailored operating system from source. What you'll learn: - Understand core Linux system concepts, including processes, file descriptors, and system calls. - Write C programs that interface directly with the Linux kernel and standard C libraries. - Configure and build custom embedded Linux filesystems and bootloaders using Buildroot. - Manage process lifecycles, signal handling, and basic input/output operations. - Apply modern practices for containerizing build environments to ensure reproducible OS builds. - Optimize root filesystems for minimal size and enhanced security profiles. The course starts with essential terminology and the architecture of the Linux kernel, then moves through core system programming APIs, and concludes with practical, step-by-step guidance for configuring your own Buildroot project. This course is designed for aspiring embedded developers, software engineers, and system administrators who are new to low-level Linux programming. No prior embedded experience is required, though a basic familiarity with command-line environments and C programming is helpful.
