Infineon Memtool 49 ((better)) Now

While it has limitations — the Windows-only requirement and restricted batch command set — Memtool's value as a free, officially supported programming tool cannot be overstated. For evaluation and development work, it's an excellent choice that will serve you well throughout the embedded development lifecycle.

When programming with Memtool 4.9, you may encounter communication or configuration faults. Here is how to resolve the most common issues: 1. "Can't connect to DAS Server" The background DAS service is stopped or missing.

Memtool is Infineon’s proprietary, low-level memory programming and debugging tool for their , AURIX™ , and legacy C166/XC166 microcontroller families. Version 4.9 represents a mature, stable release before the transition to newer tools like AURIX™ Memtool or integration into Infineon Development Studio (IDS) .

Infineon Memtool 4.9 is a dedicated production-quality software utility designed for on-chip flash programming. It supports a wide array of Infineon microcontroller families, including the AURIX, Traveo, and XMC series. This guide provides an in-depth look at using Memtool 4.9 for firmware deployment, device configuration, and troubleshooting. Key Capabilities of Memtool 4.9

Available for XMC4000 and other families. RS232: Supported for XC2000, XMC, and TriCore. 3. Integration with Infineon DAS infineon memtool 49

: Used for high-speed debugging and programming via the Device Access Port (DAP) or JTAG.

Version 4.9 primarily supports the following families:

Infineon MemTool 4.9 is a PC-based utility used for programming (flashing) and debugging Infineon microcontrollers, primarily the , TRICORE™ , and XC2000/XE166 families via bootstrap loader (BSL) or JTAG.

| Error Message | Likely Cause | Solution | | :--- | :--- | :--- | | “Bootstrap mode not entered” | Wrong pin strapping or baud rate mismatch | Double-check TMS/P0.14 state. Reduce baud rate to 9600. | | “Communication timeout” | RS232 cable is null-modem vs straight | Swap TXD/RXD pins on your connector. | | “Flash verification failed at address 0x0000” | Power supply droop during programming | Increase decoupling capacitance near VDD. | | “Device ID mismatch (expected 0x8860, got 0xFFFF)” | Target not powered or clock missing | Check oscillator startup. XTAL may need longer settling time. | | “Security bit cannot be cleared” | Permanent write lock engaged | Replace MCU. Protection is physically irreversible. | While it has limitations — the Windows-only requirement

Connect the debug cable to the target board's DAP/JTAG header. Power on the target board. Launch Memtool 4.9.

Ensure DAS drivers are updated for proper communication between the PC and the target microcontroller. Practical Application

Through the UCB configuration windows, you can alter the Boot Mode Headers (BMHD). This allows you to configure whether the chip boots from internal flash, external memory, or enters a bootstrap loader mode upon reset. Flash Protection and Locking

: If you're using an IDE (such as ADS, TASKING, or HighTec) that has compiled your code, make sure to close the IDE before launching Memtool. Otherwise, the DAS service may be occupied by the IDE, preventing Memtool from connecting properly. Here is how to resolve the most common issues: 1

: Can open Intel-Hex files to write their contents completely or partially into the memory device. Interface Compatibility

It is an official tool designed directly by Infineon for their products.

To begin using the software, users should download the latest version from the official Infineon Developer Community or Infineon software tools page . Key Setup Requirements:

Strictly speaking, Infineon has moved on. The modern Infineon ecosystem uses (part of AURIX Toolbox) for TriCore devices and iMOTION Tool for motor drives. The original MEMTool 49 is no longer officially updated.
