Cross-Compilation for ARM Targets

Set up a cross-compilation toolchain targeting ARM microcontrollers.

What is Cross-Compilation?

Compile on one platform (host) for execution on another (target). Essential for embedded development — write code on your laptop, run on a microcontroller.

A Cross-Compiler Toolchain

A toolchain bundles the cross compiler, linker, debugger, and standard libraries for a specific target.

# GCC ARM Embedded for Cortex-M
arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -O2 main.c
arm-none-eabi-objcopy -O ihex a.out a.hex
