XETK-S4.2

The XETK-S4.2 is a high speed emulator probe for the Infineon AUDO-NG, AUDO-F and AUDO-MAX microcontroller (Infineon TriCore TC17xx). It is a typical serial XETK with an Infineon specific JTAG interface. It can be connected directly to the 100 Mbit/s Ethernet Port of the host PC and supports the standard XCP communication protocol.

Configuration Parameters

The following list shows the parameters for the XETK-S4.2 device:

Hardware Settings tab

Microcontroller Type

Defines the type of the microcontroller used in the ECU.

ECU Power Supply Supervision Nominal Voltage

Selects the voltage the ETK will use for ECU power supply supervision.

ECU Watchdog Control

Selects how the XETK controls the ECU watchdog.

Controlled by ECU: The XETK will not drive the signal.
Enabled: Enables watchdog control from the XETK debugger connector. The XETK will drive the signal as configured to enable the watchdog when the debugger requests the watchdog to be enabled.
Disabled: The XETK will drive the signal as configured to disable the watchdog.

Shared functionality of DAI pin

The device is equipped with two DAI pins. These pins can either be used for DAI triggering or for sensing the ECU standby RAM power supply.

Use DAI functionality: The DAI pins are used for DAI triggering.
Sense ED supply: DAI1 is used for the sensing and DAI2 is deactivated. Only pinless or timer triggering is possible.

Handshake Timeout [ms]

Defines the hardware handshake timeout in case the ECU did not perform or does not support a hardware handshake.

To force the ECU to perform the handshake, enter -1 (infinite). Using this setting, measurement and calibration is only possible if the ECU performs the specified handshake type.

Otherwise enter a value between 0 and 65534 ms. The value should be set to the earliest time the XETK should access the ECU memory after the ECU is running (both powered and out of reset).

Handshake & Trigger Interface

Selects the method used for the hardware handshake between the ECU and the XETK, as well as for triggering a data acquisition by the ECU.

DAI: Microcontroller I/O pins are used for handshake and triggering (Data Acquisition Interrupt).
Register: Integrated functionality of the debug interface is used for handshake and triggering. No additional microcontroller pins are required.
RAM: microcontroller internal RAM is used for handshake and triggering. No additional microcontroller pins are required.

JTAG Clock Speed [MHz]

Defines the frequency used for the JTAG interface.

Trigger Register Polling Rate [µs]

Selects the polling rate in μs. Typically at least twice as fast as the fastest raster in a measurement.

Using OCON register for protocol based page switching

Determines whether the OCON register shall be used for protocol based page switching. The size and content of the Overlay Control Table written by the XETK will change based on the selected usage of the OCON register.

When migrating ETK-S4.2 to XETK-S4.2, projects must set the entry in the same way as the existing ETK configuration.

New projects are recommended to use the OCON register, default value, and consider this in the ECU software which processes the Overlay Control Table written by the XETK.

Overload Error Behavior

Defines how the XETK shall behave if an overload occurs during data processing.

Drop Data and Continue Measurement: The XETK drops measurement data, sends an error event and continues measurement.
Stop Measurement: The XETK stops the measurement and sends an error event.
