Flashbootloader_RH850_Generic

A generic automotive flash bootloader project targeting the Renesas RH850 microcontroller family. This repository is structured for integration with automotive ECUs and includes modules for EEPROM, Flash driver, hardware abstraction, and demo applications.

Features

• Support for Renesas RH850: Designed for use with the RH850 microcontroller family.
• Automotive BSW Structure: Modular Basic Software (BSW) layers for easy integration.
• EEPROM Abstraction: Wrapper drivers for EEPROM operations.
• Flash Programming: Tools and scripts to manage and program Flash memory.
• Bootloader Core: UDS (ISO 14229) diagnostics and CAN interface support.
• Demo Application: Example application for evaluation and integration.

Getting Started

Prerequisites

• Hardware: Renesas RH850 microcontroller (e.g., R7F701313EAFP)
• Compiler: GreenHills 2015.1.7 (as referenced in source comments)
• Toolchain: Standard automotive build tools (Make, batch scripts)

Build Instructions

1. Go to the Flash build directory:

   cd BSW/Flash/Build
   

2. Use the provided Makefile or batch scripts (e.g., Makefile, MkFlashRom.bat) to build the Flash driver or bootloader.
3. See Demo/DemoAppl/Appl/ for demo project files and integration examples.

Flashing & Usage

• The output can be programmed to the target RH850 MCU using standard programming tools.
• The bootloader communicates via CAN and supports ISO 14229 (UDS) services for diagnostics and reprogramming.
