About Building Bare-Metal ARM Systems with GNU
A tutorial series published on Embedded.com covering the process of building bare-metal ARM systems using GNU tools. It provides a step-by-step guide to developing low-level firmware without an operating system, leveraging the GNU toolchain (GCC, linker scripts, startup code, etc.). This resource is often referenced in embedded development communities such as the Awesome-Embedded list.
