Project Description

Flashing NXP MCX Devices with FlashRunner

Introduction

SMH Technologies offers comprehensive support for the Infineon AURIX™ TC4xx family, highperformance automotive-grade microcontrollers built on the TriCore™ architecture. These devices are widely adopted in safety-critical applications such as ADAS, powertrain management, and vehicle body domain controllers, where speed, reliability, and functional safety (up to ASIL-D) are essential.

The FlashRunner 2.0 series — including FlashRunner 2.0, NXG, and HS models — is designed to meet the stringent requirements of in-system programming (ISP) in production environments. With built-in support for Infineon’s proprietary DAP interface, FlashRunner provides a high-speed, secure, and scriptable solution for programming TC4xx devices.

Protocol and Interface Compatibility

Programming TC4xx devices relies on the DAP (Device Access Port) protocol — a robust debug and access interface developed by Infineon to provide fast and secure control of internal memory and system configuration blocks. FlashRunner 2.0 fully supports this protocol, offering automated handling of the DAP handshake, device initialization, and memory access.

Benefits in Production Programming

FlashRunner’s advanced architecture offers several advantages for programming NXP MCX devices in manufacturing lines:

  •  Fast flashing cycles, thanks to optimized handling of Infineon’s DAP protocol and internal flash algorithms.
  •  Built-in debug port unlocking, enabling recovery or rework of devices protected by userdefined passwords (when provided).
  •  Stable operation across varied setups — from single-board programming to high-density,parallel production environments.
  • No manual intervention — FlashRunner automates the entire process: connect, erase,program, verify, disconnect.

These benefits help reduce total programming time, improve process stability, and enable safe configuration of even locked or pre-initialized devices.

Conclusion

Looking ahead, SMH Technologies remains deeply committed to fostering a strong partnership with Infineon, ensuring that FlashRunner solutions continue to support future TC4xx family microcontrollers. This close collaboration guarantees seamless compatibility with upcoming devices, enabling our customers to adopt the latest innovations without disruption.

By continuously enhancing our flashing algorithms, improving protocol support, and adapting to new hardware features, SMH ensures that users benefit from state-of-the-art tools that maximize programming efficiency, reliability, and security. SMH extends beyond just delivering a flashing tool — SMH aims to provide a comprehensive ecosystem that accelerates development cycles, reduces manufacturing downtime, and simplifies integration within complex production environments.
