NXP Semiconductors CWH-ETP-BDM-HE

Overview

CWH-ETP-BDM-HE from Freescale Semiconductor is an Ethernet-based debug probe for 8-/16-bit microcontrollers, supporting BDM (Background Debug Mode) interface, 10/100BaseT Ethernet connectivity, target voltage range of 1.8V–3.3V, and full integration with CodeWarrior Development Studio for source-level C/C++ debugging.

For engineers reviewing the CWH-ETP-BDM-HE datasheet, CWH-ETP-BDM-HE pinout, CWH-ETP-BDM-HE application, or CWH-ETP-BDM-HE equivalent, this probe enables non-intrusive run-control debugging across ROM, RAM, and flash memory on Freescale 56800 Hybrid Controllers and compatible BDM-capable targets - with telnet-enabled serial port access, hardware/software breakpoints, and crash-proof processor control.

Technical Context

The CWH-ETP-BDM-HE implements a dedicated BDM protocol interface over Ethernet, enabling remote host-to-target communication without USB or serial dependency. It supports automatic signal-level adaptation (1.8V–3.3V), big/little-endian byte order, and full register/memory read-modify-write capability during halted or running states.

Unlike JTAG or COP variants, the BDM version targets Freescale's 56800-series hybrid controllers exclusively via the Background Debug Mode physical interface. It requires no target-side firmware and delivers up to 12 MB/min download speed depending on processor and target design.

Key Specifications

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) was a leading designer of embedded processors, analog and mixed-signal ICs, and connectivity solutions for automotive, industrial, and consumer applications.

The CWH-ETP-BDM-HE belongs to Freescale's CodeWarrior Ethernet TAP probe family, engineered specifically to accelerate firmware development for 56800-series hybrid controllers using BDM-based debug infrastructure.

FAQ

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

The CWH-ETP-BDM-HE supports only the Background Debug Mode (BDM) interface, designed specifically for Freescale's 56800 Hybrid Controllers. It does not support JTAG, COP, DPI, or OnCE protocols. This makes the CWH-ETP-BDM-HE incompatible with Power Architecture® or StarCore™ processors - those require other variants like CWH-ETP-JTAG-HE or CWH-ETP-DPI-HE.

Does the CWH-ETP-BDM-HE require drivers or host-side software installation?

The CWH-ETP-BDM-HE operates as a network-connected device and requires no custom USB or serial drivers. It integrates natively with CodeWarrior Development Studio v6.x–v10.x. The host PC needs only standard Ethernet TCP/IP stack configuration; no additional runtime libraries or kernel-mode drivers are needed to use the CWH-ETP-BDM-HE.

Can the CWH-ETP-BDM-HE debug code stored in flash memory on a 56800 target?

Yes, the CWH-ETP-BDM-HE fully supports flash memory debugging on compatible 56800-series targets. It enables setting breakpoints, single-stepping, and memory/register inspection directly in flash without requiring code relocation to RAM - a key capability confirmed in Freescale's CodeWarrior Ethernet TAP documentation (Rev C, 950-00175).

Is the CWH-ETP-BDM-HE compatible with modern Windows or Linux host systems?

The CWH-ETP-BDM-HE is officially supported on Windows XP/Vista/7 with CodeWarrior Development Studio. While not certified for Windows 10/11 or Linux, its Ethernet-based architecture allows potential use via network bridging and legacy VM environments. Native Linux support is not documented for the CWH-ETP-BDM-HE.

What physical connections does the CWH-ETP-BDM-HE include for target interfacing?

The CWH-ETP-BDM-HE includes a BDM-specific probe tip with 6-pin header layout matching Freescale 56800 BDM pinout, plus an extension cable and split-lead cable for targets lacking standard debug headers. It does not include JTAG adapters, COP cables, or OnCE connectors - those are provided only with corresponding variant kits.
