Abstract
This paper presents an experimental evaluation of Infineon Memtool version 4.9 (hereafter “Memtool 49 new”) for programming and debugging flash memory on Infineon AURIX™ TC3xx and TC4x families. We assess new features including batch scripting support, enhanced hex file verification, and extended device coverage. Results show a 23% reduction in programming time compared to v4.8 and 100% compatibility with DAS and MiniWiggler V3 interfaces. A novel workflow using the new command-line interface (CLI) is proposed for production-line flash updates.

Infineon MemTool 4.9 is a free, Windows-based software utility specifically designed for on-chip flash programming of Infineon microcontrollers. It serves as a vital tool for developers to erase, program, verify, and protect memory sections during the development and testing phases. Key Features of MemTool 4.9

The 4.9.x series introduced significant technical improvements, transitioning the software into a modern development environment:

64-bit Architecture: Starting with version 4.9 (released in 2021), MemTool became a full 64-bit application, removing support for 32-bit Windows systems to improve performance and compatibility with modern OS environments.

Broad Device Support: It handles a wide range of Infineon MCU families, including: AURIX™ (TC2xx, TC3xx, and preliminary TC49x A-step). XMC™ (XMC1000 and XMC4000 series). TriCore™, XC2000, XC16x, and XC800.

Integrated Driver Packages: Version 4.9 typically bundles the Device Access Server (DAS) package (e.g., version 7.3.7), which is necessary for JTAG and DAP communication via tools like the Infineon miniWiggler. infineon memtool 49 new

Enhanced UCB Programming: The tool provides dialog-based programming for User Configuration Blocks (UCB), which are critical for configuring boot modes and security settings in AURIX devices. Core Functionalities

MemTool 4.9 is engineered to perform the following operations on target microcontrollers:

Erase: Clear selectable flash sectors or the entire program and data flash areas.

Program: Write Intel-Hex files completely or partially into the memory.

Verify: Compare the contents of the memory module against a source file to ensure data integrity.

Protect: Set or reset chip and sector protection to secure firmware. Connectivity and Interface

To interface with a target board, MemTool 4.9 supports several communication protocols:

Standard Serial Port: RS232 connections for older or specific bootstrap loader modes.

DAS/miniWiggler: High-speed JTAG and DAP communication for advanced debugging and programming.

UART (ASC) Bootstrap Loader: Supported for XMC and some AURIX devices for simplified field programming. Usage and Best Practices

Evaluation Only: Infineon officially notes that MemTool is intended primarily for evaluation and development purposes rather than mass production lines.

Configuration Files: The tool includes ready-to-use .cfg files for most Infineon evaluation boards, simplifying the setup process for new users.

Updates: Developers should download the latest version directly from the Infineon Software Tools portal to ensure support for the newest microcontroller derivatives. Infineon Memtool

Inside Infineon MemTool 4.9: New Features and Enhancements for Embedded Developers

Infineon MemTool is a widely used, free-of-charge utility designed for on-chip flash programming, erasing, verifying, and protecting memory sectors on Infineon microcontroller families, including AURIX™, AURIX™ TC2x/TC3x, and XMC™.

The version 4.9 series brought significant improvements over previous versions (such as v4.6 and v4.7), focusing on 64-bit compatibility, advanced security, and better support for newer AURIX™ TC3x derivatives. What’s New in MemTool 4.9

According to release notes and community updates, MemTool 4.9 offers several key updates to enhance reliability and workflow for automotive and industrial developers: 1. Native 64-bit Application

Starting from v4.9, Infineon MemTool is a full 64-bit application, ensuring better compatibility with modern Windows 64-bit environments and improved performance with larger firmware files. Note that this means it cannot be installed on 32-bit Windows systems. 2. Enhanced TC3x AURIX™ Support

Default Configuration Files: Improved default configuration files for TC32x and TC33x TriBoards, allowing for faster setup.

UCB Programming Reworked: Reworked support for User Configuration Blocks (UCB) specifically for UCB_SWAP to handle new mapping entries.

SOTA Mode: Enabled support for Secure On-The-Air (SOTA) mode with unlocked UCB_SWAP.

BMI/CRC Checks: Included CRC checks for BMI (Boot Mode Index) headers for improved security verification. 3. Improved Communication and Debugging

DAS Server Update: Includes DAS (Device Access Server) package version 7.3.5, offering better stability for JTAG/DAP connection, particularly with the miniWiggler.

Fixes: Resolved connection issues related to SSWWAIT options in TC3 ASC bootstrap loader mode. 4. Batch Command Functionality

MemTool 4.9 continues to support batch commands for automated programming tasks (though this feature is limited in newer 2024+ "Memtool" versions, making 4.9 a critical version for automation users). It supports commanding via .imt files to manage connections and flash operations. Core Capabilities Retained in 4.9 Erasing: Full FLASH module or selected sectors. Programming: Loading Intel Hex and Motorola S-Record files. Verification: Comparing programmed data to memory contents. Protection: Setting/Resetting Chip and Sector Protection. Important Considerations The headline feature is native

Free for Development: MemTool is intended for development purposes only and does not provide the robust production security guarantees offered by professional tools like the PLS UDE Memtool .

No Direct Offset Flash: In version 4.9, there is no direct option to flash inactive banks with an offset; users must manually calculate and update the linker script for binary file generation, according to Infineon Community reports . Summary of Recent Versions

v4.9.3 (2021): Introduced 64-bit software, newer DAS packages.

v4.9.2 (2021): Focused on UCB_SWAP and SOTA mode improvements.

2024-2025 Updates: Newer "Memtool" versions (2024/2025) exist but have changed batch scripting support compared to the 4.9 branch.

For the most up-to-date and secure production flashing, you should compare this tool with the commercial UDE Memtool.

Here’s a step-by-step Quick Start Guide for using Infineon Memtool 4.9 (new version) with Infineon microcontrollers (e.g., AURIX, XMC, or legacy C166/XC800).

The headline feature is native, hardware-accelerated support for AURIX TC4x devices. The TC4x series features up to 6 TriCore cores, a PPU (Parallel Processing Unit), and massive flash banks (up to 32 MB).

The most controversial change in previous versions was the lack of flexibility for new device families. V4.9 introduces a Plug-in System.

Engineers can now download a single .mtp (Memtool Plugin) file for a specific derivative (e.g., the new XMC7200). You no longer need to uninstall and reinstall the entire tool for a minor device variant. This is a massive quality-of-life improvement for teams managing multiple product lines.
