Build System

Overview

The Mimic firmware uses a standard Makefile-based build system designed for the GNU Arm Embedded Toolchain. This ensures that the code can be compiled and deployed from any standard Linux, macOS, or Windows terminal.

Requirements

To build the firmware, you need:

arm-none-eabi-gcc: The cross-compiler for ARM Cortex-M microcontrollers.
make: The build automation tool.
st-flash (or OpenOCD): For uploading the binary to the STM32 board.

Compilation Commands

make — Compiles the source files and generates the binary image.
make clean — Removes all compiled objects and binaries.
make flash — Compiles and uploads the code to the connected STM32 via an ST-Link.

Output Files

The build process produces several files in the build/ directory:

mimic.bin — The raw binary image for flashing.
mimic.elf — The executable file containing debug symbols.
mimic.hex — The Intel Hex format version of the binary.
