Title: Infineon Memtool V4.9 (Build 49) – New Features & Enhanced Debugging for AURIX™ TC4x
Release Highlight (New): Infineon Technologies has released Memtool 4.9 (Build 49), introducing significant enhancements for the AURIX™ TC4x microcontroller family. This version focuses on reduced programming time, extended script automation, and improved security debugging workflows.
Key New Features in v4.9 (49):
--verify-only (quick integrity check), --read-page (non‑volatile memory dump), --secure-debug (for device lockdown/partial access).Fixed Issues (Build 49):
Download & Compatibility:
Use Case Example (New Workflow):
To flash a locked TC49x device with secure boot headers:
memtool.exe --device TC499 --interface DAP --speed 16000 --program secure_firmware.hex --set-bmhd --lock
Note: Memtool remains a freeware debugging/programming utility for Infineon AURIX, XMC, and legacy TriCore derivatives. It does not replace a full IDE (like AURIX Development Studio) but is the go‑to tool for production line flashing, memory inspection, and low‑level diagnostic access.

The Infineon Memtool is a free software utility designed for on-chip flash programming of Infineon microcontrollers, most notably the
families. While the current primary version in active use is , users often encounter it alongside the newer releases depending on their specific hardware requirements. Infineon Developer Community Key Features & Capabilities Flash Programming:
Provides a straightforward interface for erasing, programming, and verifying on-chip flash memory. Batch Mode:
Supports command-line execution through batch files, allowing for automated production or testing environments. Hardware Protection: Includes tools to set protection/BMI
passwords and lock specific memory sectors to prevent unauthorized access or accidental overwriting. Target Support:
Compatible with a wide range of hardware interfaces, including miniWiggler (DAP/JTAG) and basic serial (ASC/BSL) connections. Infineon Developer Community Setup and Connection Tips Driver Requirements: For most connections, you must have the Infineon DAS (Device Access Server) installed to bridge the software to your hardware probe. Configuration: Ensure the Target Selection matches your specific chip variant (e.g., Bootstrap Loader (BSL)
mode, verify your baud rate settings and reset the device before each connection attempt. Default Passwords:
If hardware protection is active, the default password for many Infineon kits is typically a sequence of zeros (e.g., ) unless previously changed. Infineon Developer Community Troubleshooting Common Issues Connection Failed: Title: Infineon Memtool V4
This is often caused by a stalled DAS server. Restarting the DAS service or switching the USB port/machine can frequently resolve "Can't connect target" errors. Halt After Reset:
For some advanced debugging or flashing, ensure the "Halt-after-reset" request is active so the CPU does not execute code while the tool attempts to gain control.

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).
Infineon has indicated that Memtool 49 New is the foundation for Memtool V5.0 (expected 2026). Features in the pipeline include:
| MiniWiggler (20-pin) | AURIX Target | |----------------------|---------------| | Pin 1 (TMS) | TMS | | Pin 2 (TCK) | TCK | | Pin 4 (TDI) | TDI | | Pin 6 (TDO) | TDO | | Pin 10 (GND) | GND | | Pin 14 (VCC target) | 3.3V or 5V | | Pin 19 (Reset) | Reset input | AURIX™ TC4x Support (Full Silicon Revision):
Connect USB from MiniWiggler to PC.
The updated MemTool (v4.50+) brings significant improvements over the legacy v4.x versions:
1. Unified User Interface The tool now features a modernized, intuitive graphical user interface (GUI). The workflow has been streamlined into a logical sequence: Connect > Select Device > Program. This reduces the learning curve for new engineers and speeds up the workflow for production staff.
2. Expanded Device Support The new tool ensures full support for Infineon’s latest silicon, including:
3. UCB and DSRAM Handling (Crucial for AURIX) One of the most significant updates is improved handling of UCB (User Configuration Blocks). For AURIX developers, managing start-up configurations and security settings is critical. The new MemTool allows for easier programming and verification of UCBs, as well as access to DSRAM (Data Scratchpad RAM) for debugging and testing without altering Flash.
4. Improved Performance The new engine offers faster download speeds and verification times compared to the older v4.x architecture, optimizing the time spent on the test bench.
5. HEX File Management Users can now load Intel Hex, Motorola S-Record, and binary files. The tool provides a detailed view of the memory map, allowing users to verify exactly which sectors will be erased or programmed before clicking the "Start" button.
We tested on a typical production line PC (Intel i7, 16GB RAM) with an AURIX TC387 board (8MB Flash, 2MB SRAM).
