Note: Infineon is gradually transitioning some users to the DAVE™ IDE or Aurix Development Studio (ADS), which have built-in flashing tools, but MemTool remains the standard standalone tool for production line flashing and field updates.
Understanding Infineon Memtool 4.9: A Guide to Flash Programming
Infineon Memtool 4.9 is a free, Windows-based software tool designed for on-chip flash and OTP (One-Time Programmable) memory programming across a wide range of Infineon microcontrollers. As a production-ready utility, it allows engineers to erase, program, verify, and protect memory modules using standard communication interfaces. Key Features of Memtool 4.9
The 4.9 release continues the tool's legacy of providing a streamlined interface for firmware management. Its core capabilities include:
Comprehensive Memory Operations: Users can erase entire memory modules or specific sectors, and program data from standard Intel-Hex files.
Verification and Protection: The tool includes functions to verify programmed data against the source file and set or reset chip/sector protection to secure intellectual property.
Batch Command Support: Version 4.9 supports automation through batch commands, allowing for repetitive programming tasks in production or testing environments without manual GUI intervention. infineon memtool 49
Ready-to-Use Configurations: It comes with pre-configured files for the full range of Infineon evaluation boards and application kits. Supported Microcontroller Families
Infineon Memtool 4.9 is versatile, supporting several major 8-bit, 16-bit, and 32-bit architectures:
AURIX™ & TriCore™: High-performance 32-bit MCUs used heavily in automotive and industrial safety applications.
XMC™ Series: Both the XMC1000 (ARM® Cortex®-M0) and XMC4000 (ARM® Cortex®-M4) families.
Legacy Families: Includes support for XC800, XC16x, and XC2000 microcontrollers. Hardware Connectivity
To interface with a target device, Memtool 4.9 utilizes several standard connection methods: Note: Infineon is gradually transitioning some users to
Serial Interface: Supports standard RS232 and UART (ASC) bootstrap loaders.
DAS (Device Access Server): Enables high-speed communication via JTAG and DAP (Device Access Port) interfaces.
miniWiggler: This is the recommended external hardware tool for establishing DAP and JTAG connections between the host PC and custom target boards. How to Use Memtool 4.9 for Programming
Microcontroller Reprogramming Procedure via Infineon Memtool
Memtool is Infineon’s proprietary, low-level memory programming and debugging tool for their TriCore™, 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).

Batch flash without GUI:
Memtool.exe -d TC277 -i "firmware.hex" -e -p -v -c DAS:USB:0
Example .mts script (flash_script.mts):
connect DAS:USB:0
halt
erase 0x80000000 0x80040000
load "app.hex" binary 0x80000000
verify "app.hex" binary 0x80000000
go 0x80000000
disconnect
Execute via: Memtool.exe -s flash_script.mts
