Infineon | Memtool 49 New

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: infineon memtool 49 new

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:

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: The Infineon Memtool is a free software utility

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. Infineon Developer Community batch commands for version 4.9 to help automate your flashing process? TC214L-8F133 and Memtool - Infineon Developer Community

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).

"Memtool 49 New": Decoding the Version Number

You might be wondering why "49" is significant. The previous stable release was V4.8. The jump to V4.9 is not a simple point release; it represents a fork in functionality. The "New" moniker attached by the community refers to the new architecture underneath.

Infineon Memtool V4.9 was first teased at the 2024 Embedded World conference, with general availability rolling out in Q1 2025. It is a complete rewrite of the backend driver layer, moving from a device-specific hard-coded logic to a unified, Hexagon-based dynamic linking system.

Known Issues and Workarounds (As of Build 4921)

No tool is perfect. As of the "New" release (Build 4921), the community has identified a few quirks:

1. First-time GUI Lag: The new Qt-based GUI (moved from MFC) takes ~2 seconds longer to render the device selector on first launch. This resolves after the cache builds.
2. Legacy Parallel Port Wiggler: V4.9 has dropped support for the ancient parallel-port Wiggler. You must use USB-based debuggers.
3. CAN Programming: The asynchronous CAN bootloader is currently limited to 500kbps (down from 1Mbps in V4.8). Infineon has promised a patch by Q3 2025.

4. Configuring Memtool for First Use

1. Select device
   File → New Project → Choose microcontroller series
   Example: AURIX → TC2xx → TC297

2. Configure interface
   Settings → Communication → Interface

   • Choose: MiniWiggler V3 (or DAP)
   • Port: USB
   • Leave default speed (e.g., 10 MHz)

3. Test connection
   Target → Connect
   You should see:

   Connected to device: TC297
   Core status: Halted
