ETK-S21.0A / ETK-S21.1A
The ETK-S21.0A and ETK-S21.1A are ETK for the JDP MPC57xx microcontroller family.
These serial ETK can be used for measurement and calibration applications, rapid prototyping, and flashing.
The ETK-S21.0A and ETK-S21.1A are connected to the calibration and development system with 100 Mbit/s.
Configuration Parameters
The following list shows the parameters for the ETK-S21.0A and ETK-S21.1A devices:
Defines the type of the microcontroller used in the ECU.
Defines the frequency used for the JTAG interface.
The (X)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 (X)ETK signals to the (X)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 (X)ETK signals to the (X)ETK that the ECU has finished its initialization.
- NO: The CalWakeUp pin is pulled until the microcontroller core voltage (VDDP) is high.
Controls if the watchdog disable feature of the ETK is enabled or disabled.
- NO: The watchdog disable mechanism is not used, hence the watchdog is enabled all the time.
- YES: The watchdog is disabled when a debugger gets connected to the ECU or if PROF flashing is ongoing.
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 signal the (X)ETK will use for ECU standby RAM (working page) power supply supervision.
- ETK Standby Supply: (X)ETK is monitoring the standby supply it provides to the ECU.
- No Standby Supply: (X)ETK is monitoring the standard ECU power supply; the working page is not using a standby supply.
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.
-
Register Triggering: The ETK uses register based handshake.
If this option is selected, Register must be selected for Handshake Startup Message and Infinite must be selected for Handshake Timeout.
-
Timer Triggering: In case that the ECU does not support handshake, select this option so that the ETK simulates a handshake. The ETK reports a successful handshake completion to the software after the time selected via Handshake Timeout has elapsed.
If this option is selected, Timeout must be selected for Handshake Startup Message and one of the timeout values must be selected for Handshake Timeout.
Select the trigger to start up handshake. The same option should be selected under Handshake & Trigger Interface.
- Register: Use Register Triggering.
- Timeout: Use Timer Triggering.
Select the timeout value for the handshake.
- Infinite: This option must be selected for Register Triggering.
- timeout values (1 ms, 10 ms, …): Select one of the timeout values if Timer Triggering is used. ETK will report a simulated successful handshake completion to the software after the selected time has elapsed.
Selects the polling rate in μs. Typically at least twice as fast as the fastest raster in a measurement.
Selects the voltage the (X)ETK will use for the emulation RAM of the ECU.
Defines the access to the emulation device.
- Default: The emulation device is accessed via a dedicated calibration bus.
- PD Core Access: The emulation device is accessed via the bus of the production device.
Defines if the ETK shall communicate with the ECU via JTAG or via LFAST.
Defines the bit rate of the LFAST communication. To use this parameter, Interface Type must be set to LFAST.
Defines the frequency of the reference clock of the ECU. To use this parameter, Interface Type must be set to LFAST.
