Add a production-ready, educational bootloader extension for STM32 MCUs. Core features: - Custom binary protocol with CRC16/CRC32 verification - AES-256 encryption for firmware security - Dual-bank firmware management with rollback support - Version management and firmware validation - Modular architecture with BSP abstraction layer Project structure: - include/: Header files (bootloader.h, bsp_flash.h, bsp_uart.h) - src/: Core implementation (bootloader, protocol, crypto, firmware manager) - port/: MCU-specific adaptation layer (STM32F4xx) - docs/: Documentation (integration guide, porting guide) Supported platforms: - STM32F4xx (primary) - STM32F1xx (via porting) Quick start: 1. Copy extension module to project 2. Configure bootloader_config.h 3. Modify linker script for APP_BASE_ADDR 4. Build and flash bootloader to 0x08000000 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
