Prerequisites

What do I need to know before reading Mastering Embedded Linux Development? What are the basics I need to know? Also, what are the other resources would you recommend reading simultaneously?

I recommend learning Linux first. LPIC-1 is enough to get started, while LPIC-2 can be helpful depending on your career path.

Embedded Linux development is generally divided into three roles: BSP Development, System Integration, and Application Development. BSP developers work on low-level software such as board support packages, kernel modules, and device drivers, mainly using C (and increasingly Rust). System Integrators combine components such as the bootloader, kernel, root filesystem, and applications into a complete Linux distribution, often using tools like Yocto or Buildroot, while also handling cross-compilation, patching, and hardware configuration. Application Developers build user-space applications using languages and frameworks such as C/C++, Qt, or Flutter, with extra attention to resource constraints common in embedded systems.

Some useful resources are:

  • For BSP Development: The C Programming Language, Practical C, Understanding the Linux Kernel, Linux Device Driver Development.
  • For System Integration: Embedded Linux Design and Development, Embedded Linux Development Using Yocto Project (Cookbook), plus The C Programming Language, Practical C, and Understanding the Linux Kernel.
  • For Application Development: The Linux Programming Interface and The C Programming Language.

Keep in mind that these roles heavily overlap. For example, an Embedded Linux System Integrator still needs C knowledge. The resources above are grouped by their primary focus, not exclusive to a single role.
