bootloader.
- Recipes: Writing and managing scripts to build and include software components in the final
image.
- Layers: Organizing and managing configurations and software packages in structured layers,
including BSP (Board Support Package) for hardware support.

BuildRoot expirience:
- Target Architecture: Selecting and configuring the CPU architecture (e.g., ARM, x86) and its
specific settings.
- Toolchain Configuration: Setting up or selecting the appropriate toolchain for building the
system.
