A tour of GNU binary tools for embedded systems

In this section, we’ll delve into the GNU Bin tools, a suite of tools that come with the installation of the GNU Toolchain for Arm. These tools (commands) are essential for the various stages of the firmware build process, as well as additional tasks such as debugging.

The first command we’ll explore is arm-none-eabi-gcc.

arm-none-eabi-gcc

Let’s break down the components of the command:

• arm: This specifies the target architecture.
• none: This component indicates the operating system for which the code is being compiled. Here, none signifies that the code is meant for a bare-metal environment, meaning it will run directly on the hardware without an underlying operating system.
• eabi: This stands for Embedded Application Binary Interface. EABI defines a standard for the binary layout of system and user programs, libraries, and so on. It ensures that the compiled code will work correctly on any...
