XETK-S31.0
The XETK-S31.0 is a high speed emulator probe designed for the Freescale and ST MPC57xx microcontroller family. 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-S31.0 device:
Defines the type of the microcontroller used in the ECU.
Defines the frequency used for the JTAG interface.
Selects the polling rate in μs. Typically at least twice as fast as the fastest raster in a measurement.
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).
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.
Controls which level of the watchdog disable signal shall disable the watchdog.
- Low: Low level shall disable the watchdog.
- High: High Level shall disable the watchdog.
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.
- Pinless Triggering: Integrated functionality of the debug interface is used for handshake and triggering. No additional microcontroller pins are required.
The ETK has the ability to wake up the ECU by applying voltage to the CalWakeUp pin of the ECU connector. This makes it possible to download the content of the working page and configure a measurement while the ECU is off.
When waking up the ECU via the CalWakeUp pin it can be selected whether the pin is pulled until the microcontroller core voltage (VDDP) is high or whether the pin should be kept on high state until the start-up handshake between ECU and ETK signals to the ETK that the ECU has finished its initialization.
- YES: The CalWakeUp pin will be kept on high state until the start-up handshake between ECU and ETK signals to the ETK that the ECU has finished its initialization.
- NO: The CalWakeUp pin is pulled until the microcontroller core voltage (VDDP) is high.
Selects the voltage the ETK will use for ECU power supply supervision.
Selects the voltage the ETK will use for ECU standby RAM (working page) power supply supervision.
Selects the signal the ETK will use for ECU standby RAM (working page) power supply supervision.
- ETK Standby Supply: ETK is monitoring the standby supply it provides to the ECU.
- ECU Standby Supply: ETK is monitoring the ECU standby supply; the ECU is not using the standby supply from the ETK.
- No Standby Supply: ETK is monitoring the standard ECU power supply; the working page is not using a standby supply.
Selects how the ETK controls the JTAG signal /TRST (JCOMP) for JTAG initialization:
- Default: The ETK asserts /TRST for a short pulse on both /RESET and /RSTOUT events.
- Asserted with /RESETin: The ETK asserts /TRST for a short pulse only on /RESET events. /RSTOUT has no effect on /TRST control. On MPC5746M for example, debug breakpoints and trace configuration will remain valid through /RSTOUT events
- Asserted with /RESETin and /RESETout: The ETK asserts /TRST for the duration of both /RESET and /RSTOUT events. On MPC5746R for example, this setting is required on certain revisions when using the built in self test (BIST) module.
Selects the standby voltage the ETK will provide to the ECU for the working page.
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.
