NXP Semiconductors CWH-ETP-DPI-HE

Overview

CWH-ETP-DPI-HE from Freescale Semiconductor is an Ethernet-based debug probe supporting DPI (Debug Port Interface) connection to Power Architecture®, StarCore™, and 56800 Hybrid Controller targets; delivers 12 MB/min host-to-target download speed, 1.8–3.3V target voltage support, JTAG/COP/DPI/OnCE port compatibility, and full CodeWarrior Development Studio integration for ROM/RAM/flash debugging.

For engineers reviewing the CWH-ETP-DPI-HE datasheet, CWH-ETP-DPI-HE pinout, CWH-ETP-DPI-HE application, or CWH-ETP-DPI-HE equivalent, this page details its role as a low-intrusion, Ethernet-connected run-control probe enabling register/memory inspection, hardware/software breakpoints, telnet-based serial access, and crash-proof target control in embedded firmware development workflows.

Technical Context

The CWH-ETP-DPI-HE implements a dedicated Ethernet TAP (Test Access Port) architecture that bridges host PC debugging tools over 10/100BaseT to target processors via DPI physical interface, with automatic signal-level adaptation across 1.8V–3.3V logic domains. It supports both big- and little-endian core configurations without host-side reconfiguration.

Unlike USB or parallel-port debug probes, the CWH-ETP-DPI-HE operates as a networked node with built-in TCP/IP stack, enabling remote telnet access to the target's serial port and decoupling debug sessions from physical proximity-critical for lab-distributed or production-line bring-up environments.

Manufacturer

Freescale Semiconductor was a fabless semiconductor company specializing in embedded processing, connectivity, and analog solutions before its acquisition by NXP in 2015; known for Power Architecture, ColdFire, and Kinetis microcontroller families.

The CWH-ETP-DPI-HE belongs to Freescale's CodeWarrior Ethernet TAP probe family, designed specifically to accelerate low-intrusion, network-based firmware debugging for Freescale processor evaluation and production board bring-up.

FAQ

What is the primary debug interface supported by the CWH-ETP-DPI-HE?

The CWH-ETP-DPI-HE primarily supports the DPI (Debug Port Interface) for direct processor communication, but includes interchangeable probe tips enabling use with JTAG/COP or OnCE ports depending on target system implementation. This flexibility allows the same CWH-ETP-DPI-HE unit to serve multiple Freescale processor families without hardware modification.

Does the CWH-ETP-DPI-HE require a dedicated driver installation on the host PC?

No, the CWH-ETP-DPI-HE operates as a standard Ethernet node with built-in TCP/IP stack and requires no proprietary USB or parallel-port drivers. It communicates natively over standard Ethernet protocols, integrating transparently with CodeWarrior Development Studio via IP address configuration - simplifying deployment in virtualized or locked-down engineering environments.

Can the CWH-ETP-DPI-HE be used with non-Freescale processors?

The CWH-ETP-DPI-HE is engineered and validated exclusively for Freescale Power Architecture®, StarCore™, and 56800 Hybrid Controller targets. Its DPI protocol timing, voltage adaptation logic, and CodeWarrior integration are not guaranteed for third-party architectures, and no official support or documentation exists for non-Freescale silicon.

How does the CWH-ETP-DPI-HE handle different target voltage levels?

The CWH-ETP-DPI-HE automatically detects and adapts to target I/O voltage levels between 1.8V and 3.3V without jumper settings or external components. This ensures safe, reliable signaling across mixed-voltage boards and eliminates manual configuration errors during bring-up of new Freescale reference designs.

Is telnet access to the target serial port a built-in feature of the CWH-ETP-DPI-HE?

Yes, the CWH-ETP-DPI-HE provides native telnet server functionality that forwards TCP connections to the target system's UART, allowing remote terminal interaction over Ethernet. This feature is enabled by default and requires no additional host software - making it possible to monitor boot logs or issue commands from any networked workstation using standard telnet clients.
