Renesas Configuration Script Manager

Configure, validate, and program the eNVM Configuration Script area on a Renesas RA6Bx device family through a guided interface.

Supported Devices

Overview

The Renesas Configuration Script Manager extension helps developers:

• Connect to hardware - Discover and connect to target devices over serial
• Read device configuration - Fetch configuration script contents from eNVM/device memory
• Edit with guardrails - Add and modify configuration rows with validation rules
• Program safely - Write configuration scripts with chunked transfer, progress reporting, and verification
• Erase intentionally - Invalidate or clear configuration regions where supported by the device protocol
• Track operations - Review logs and operation status directly in the UI

This extension is designed for teams that need repeatable, auditable configuration script workflows for production and validation.

Features

Device Connectivity

• Automatic serial port discovery
• Connect and disconnect controls from within the extension UI
• Firmware query support to check connected device version

Configuration Script Operations

• Read CS - Load configuration script words from device memory
• Write CS - Program script words in HCI-framed chunks with progress updates
• Erase CS - Issue erase/invalidate operation and verify resulting state
• Abort - Cancel active script transmission when needed

Data Integrity and Safety

• Word normalization and payload validation before write
• Post-write verification through read-back comparison
• Boundary checks to detect unexpected trailing data
• Error reporting with mismatch details when verification fails

User Experience

• Tabular configuration view for readable editing
• Save/load project data in JSON format
• Integrated user manual panel
• Consistent logging for device and operation events

Getting Started

Installation

1. Install the extension from your internal distribution channel, as VSIX package or directly from the marketplace
2. Connect the Renesas RA6Bx device to your machine via USB/serial
3. Start the tool operation

Quick Start (5 Minutes)

1. Open the extension

   • Press Ctrl+Shift+P (Windows/Linux) or Cmd+Shift+P (macOS)
   • Type "Renesas Configuration Script Manager" and press Enter
   • The extension UI opens in a WebView panel

2. Connect your device

   • Select a detected serial port in the UI
   • Click Connect

3. Read current configuration

   • Click Read CS to fetch device script content
   • Review rows in the configuration table

4. Apply new CS entris

   • Edit existing rows or add new entries
   • Click Write CS to program changes

5. Verify and save

   • Confirm post-write verification status in logs
   • Save the project configuration as JSON for traceability

Commands

• Start Server: Starts backend HTTP/WebSocket services
• Stop Server: Stops backend services and releases the port
• Show UI: Opens the main Configuration Script webview
• Renesas Configuration Script Manager: Starts server and opens the UI in one step

Troubleshooting

• No serial ports detected - Verify cable, target power, and serial drivers
• Cannot connect to device - Ensure no other tool holds the COM port
• Write verification failed - Re-read CS data and validate row ordering/content
• UI missing or blank - Rebuild UI assets and restart the extension host

Known Limitations

• Boot-critical configuration region - The Configuration Script area is parsed by the device ROM bootloader. Invalid entries, malformed data, or interrupted programming can leave the device in a non-bootable state and permanently unusable
• Hardware compatibility - This tool targets supported Renesas devices and firmware that implement the expected CS protocol
• Serial exclusivity - Device COM ports must be exclusively owned by this extension during active sessions
• Write sensitivity - eNVM-like write operations are hardware-sensitive; interruptions can require reconnect and full re-read before retry
• Environment differences - Web-hosted environments can behave differently from desktop due to browser/device access constraints
