4.1.3XETK-V2.0B Interface Concept
The XETK-V2.0B connects to the ECU in a similar manner to other serial (X)ETKs,
using a cable with a standard debugging interface connector. The XETK-V2.0B is
equipped with a 50 pin Nexus Samtec connector and connects to the ECU using
an ETAHx ECU adapter cable.
The ETAH1 ECU adapter cable offers a connection to an EC
U equipped with a 38
pin Mictor connector. Other ETAHx variants are possible.
4.2Architecture
Fig. 4-4XETK-V2.0 Architecture
The XETK-V2.0’s primary interface to the
development ECU is the Nexus / JTAG
interface of the microcontroller. This interface is available at the VertiCal connector of the XETK-V2.0A/C or the Samtec co
face provides the XETK access to the same m
nnector of the XETK-V2.0B. This inter-
emories accessible to the
microcontroller, including both internal and/or external Flash and/or RAM. The
XETK-V2.0 can only access these memories while the microcontroller is powered
and out of reset.
The XETK-V2.0A/C provides a SRAM the developm
lation memory and/or as measuremen
t data memory. The XETK-V2.0A/C
ent ECU can use as data emu-
accesses this SRAM in the same way as other development ECU memories, via
the microcontroller’s Nexus /JTAG interface.
While the microcontroller accesses the program dat
a (not the program code) out
of the data emulation memory provided by either the XETK-V2.0A/C or the ECU,
the content of the data emulation memory can simultaneously be modified by
the calibration and development system through the XETK Ethernet interface.
This process enables adjustments of parameters, characteristic lines and maps
through the calibration and development system. Using an additional measurement data memory area, the ECU microcontroller can provide data to the calibration and development system by buffering the data (DISTAB13) and triggering
XETK to read the data via JTAG. The XETK then reads, buffers, processes and
the
sends this measured data to the PC.

For a complete list of the pins of the XETK-V2.0A/C ECU interface refer to
section 7.11.1 on page 72 and to section 7.11.3 on page 79 for the XETK-V2.0B
ECU Interface. In general the interface of each device consists of:
• ECU voltage lines, which are not used for powering the XETK, but for
de
tecting the ECU status; therefore the power consumption on these lines
is negligible (refer to chapter 4.4 on page 23)
• Data Acquisition Interrupt lines (DAI
lines) which are used for XETK synchronization at startup and for Data Acquisition (refer to chapter 4.11.4
and 4.11.5)
• Reset lines which allow the XETK to bot
h monitor and control the system
reset of the ECU (refer to chapter 4.7 on page 26)
• JTAG Interface used as the measur
ement and calibration interface
between the XETK-V2.0 and the microcontroller (refer to chapter 4.9
on page 29)
• Nexus Auxiliary Interface used as an optional mea
surement interface
between the XETK-V2.0 and the microcontroller
4.4Power Supply
The XETK-V2.0 needs a permanent power supply. It is powered directly from the
car battery. The input voltage may vary between 4.3 V and 36 V
Fig. 4-7Power Supply monitoring
All necessary voltages required by the XETK
are created through switching power
supplies which minimizes heat build-up. The power supply of the ECU is not
affected by the XETK-V2.0. An automatic switch ensures that the power supply
of the XETK-V2.0 is automatically switched on and off. The ECU voltage VCC
(V_RESET for XETK-V2.0A/C and V_NEXUS for XETK-V2.0B) is monitored by the

4.7Reset
The requirement for XETK reset mechanism is to ensure that power-up and
power-down behavior of ECU is clean and to prevent corruption of data stored
in the XETK-V2.0A/C’s SRAM.
To accomplish this the XETK-V2.0 senses the microcontroller power supply at the
E
CU interface connection; V_RESET of the XETK-V2.0A/C and V_NEXUS of the
XETK-V2.0B. This allows the XETK to detect when the ECU is off and forward this
information to INCA. In addition, it allows the XETK to enter the power save
mode if the ECU is off and the PC is off or unplugged.
Furthermore, the XETK-V2.0 se
write protect signal for its memory. If configured, the /RSTOUT line can also be
used to sense the status of the ECU reset.
Finally, the XETK-V2.0 generates a reset signal
in reset while the XETK is in power save mode and to prevent the microcontroller
from starting until the XETK is ready to work.
The XETK is ready to work when it has finished
power save mode or after initial power-up. This feature allows it also to reset the
ECU under tool control (required for INCA and ProF) and to perform an emergency stop of the ECU in case of XETK failure.
4.8Data Emulation Memory
The XETK-V2.0 is a serial XETK using JTAG / Nexus as its primary microcontroller
interface. Typical of all serial XETKs, the RAM used for data emulation and data
measurement is not accessible by the XETK until the microcontroller is powered
up and the startup handshake is performed. This includes the 2 MByte of SRAM

The Reference Page is located in the ECU flash and can not be modified by a
simple write access. All changes to the Reference Page must be done via Flash
programming. The INCA user can use ProF to invoke a customized flash programming algorithm.

ETK-V2.0A/C’s on board SRAM. The Working Page may be a portion of or the

4.8.1Page Switching
To enable calibration, the Working Page must be activated. The process of
switching from the Reference Page to the Working Page and vice versa is known
as page switching. The XETK-V2.0 supports two methods of page switching;
however, one method is only available for certain microcontrollers.
Regardless of which page switch method is used and which page is activated
rom the microcontroller’s point of view, both the Reference Page and Working
f
Page are accessible for standard operations using INCA such as upload or checksum calculations.
Protocol Based
The XETK-V2.0 supports Protocol Based page switching for all supported microcontrollers. Switching between Reference and Working Page is done in microcontroller software by re-directing accesses to calibration data between either
Flash (Reference Page) or the RAM (Working Page) using microcontroller
the
internal mechanisms. The XETK-V2.0 does not directly control the microcontroller mechanism used to do this re-direction. Instead the XETK-V2.0 and microcontroller software share a mailbox in RAM. The XETK use
and monitor page switching; the microcontroller is responsible to service this
mailbox and perform the page switches.
Direct Register Access
The XETK-V2.0 supports Direct Register Access page switching for microcontrollers which provide additional internal registers for page switching. Switching
etween Reference and Working Page is done in microcontroller hardware by re-

4.8.3Data Emulation Power Failures
The XETK-V2.0 has a circuit which recognizes and stores power failures. The
XETK-V2.0 will notify the microcontroller software of the power failure using the
DAI pins and additionally will prevent the user from switching to the working
page until the PC software has downloaded a new Working Page data into the
data emulation memory.
The calibration feature "start on working page" or "start on last active page
with the last active page being the working page" is only possible when the
working page has been downloaded since the last power failure. Until a down
load occurs after a power failure the micro
controller software is informed of a
power failure by the DAI pins and is responsible to make the reference page
active.

CAUTION!
The microcontroller is mounted directly on the VertiCal Base Board; therefore it
is not possible to add additional series resistors between the microcontroller and
XETK for TDO, /RDY, /EVTO, MCKO, MDOx, and /MSEOx.
When the ECU design incorporates JTAG /
Nexus connectors, additional circuitry
is required to ensure these connectors and the signal routing do not influence
the interface between the microcontroller and XETK. The ECU must incorporate
0 Ohm series resistors on every signal which goe
s to an additional JTAG / Nexus
connection. Additionally, the resistors must be placed as close to the microcontroller as possible; especially for TCK and MCKO. For proper operation of the
ETK-V2.0A/C it is mandatory to depopulate these resistors (e.g. not present), as
X
shown in Fig. 4-12. For ECUs used without the XETK-V2.0A/C, the resistors can
be populated to provide functional JTAG / Nexus connectors.
Risk of damaging the XETK due to short circuiting the JTAG
signals!
When the XETK-V2.0A/C is connected to the ECU, you must ensure
that no other device is actively driving the JTAG signals (TCK, TDI,
TMS) via another connector on the ECU (e.g. Lauterbach debugger
directly on ECU pcb). To use these other tools you must remove the
XETK-V2.0A/C or plug the other tools into the ECU via the XETKV2.0A/C’s NEXUS (JTAG) Debugger Connector.
