Understanding the Build Process and Exploring the GNU Toolchain
Bare-metal programming is a journey of deep understanding and precision, and in this chapter, we will navigate the complex realm of the embedded firmware build process. Our focus is the GNU Arm Toolchain, an important element in firmware development. Through a blend of theory and hands-on programming exercises, you will gain insights into how integrated development environments (IDEs) streamline the build process and how these processes can be manually replicated using the GNU Arm Toolchain.
As the chapter progresses, we delve into the nuances of the compiler and its various options, tailored for Arm Cortex microcontrollers. The programming exercise in this chapter is designed to help you understand and effectively utilize the GNU tools, from compiling and linking to analyzing the depths of the output object files.
In this chapter, we shall cover the following main topics:
- The foundations – understanding...
