Porting Guide

Adding a new MCU target requires implementing six driver modules and one configuration header. The bootloader core (src/main_app.c) does not need modification.

Steps at a Glance

1. Copy hw/STM32_TEMPLATE/ to hw/<YOUR_TARGET>/
2. Fill in Core/Inc/bl_hw_config.h with your MCU's memory map and timing constants
3. Implement the six driver modules in Core/Bl_drv_interface/
4. Write Core/Src/main.c — the hardware entry point
5. Add a linker script and toolchain file
6. Add a CMakeLists.txt following the existing target pattern
