Introduction
Cypress CYT2B7 Emulation Adapter is based on the 176-pin CYT2B78CA superset device and
provides full trace capabilities for the:
· 64-pin
· 80-pin
· 100-pin
· 144-pin
Traveo II CYT2B7 Adaptation, where trace port is not available or lacks the full trace capability.
The Emulation Adapter might differ in some peripherals from the target device; there-
fore, the device datasheet should be checked.
Cypress CYT2B7 Emulation Adapter supports following debug and trace interfaces:
· JTAG or SWD debug interface;
· MTB trace to trace Cortex-M0+ program execution; Trace data is stored in 4KB dedicated RAM
memory and read out through JTAG or SWD;
· ETM/ITM trace to trace Cortex-M4 program execution; Trace data is connected to the external
trace port (CPU port P18_4 – P18_7 or P22_0 – P22_3) which then connects to 20-pin 1.27
mm CoreSight Debug Adapter;
· ETB trace to trace Cortex-M4 program execution; Trace data is stored in 8KB dedicated RAM
memory and read out through JTAG or SWD;
· Serial wire viewer (SWV) and printf() style debugging through a Single Wire Output (SWO)
“trace” pin on Cortex-M4.
Emulation Adapter can also be used as a standalone device for microcontroller evaluation pur-
poses or for development and test of an embedded application ahead of target board availabil-
ity.

Measurement board
The Measurement board connects between the Emulation Adapter and the Conversion board.
Embedded targets often do not have access to all the MCU pins / connected signals to connect
with measurement equipment (oscilloscope, logic analyzer), its use provides easy access to all
MCU pins. It is delivered together with an Layout board (chip signals are clearly marked), which
is placed over the Measurement board.

Screws
Slot screw
The Slot screw (30mm) is used to fix the Conversion board to the Solder part. The setup be-
comes mechanically more robust.Screw the Conversion board to the Solder part first, before the
Emulation Adapter is attached on top and watch out not to break out the Solder part, e.g., if you
accidentally hit the Emulation Adapter from the side.
Short Hexagon socket screw
Short Hexagon socket screw, which comes with the Solder part, is not applicable with this Emu-
lation Adapter setup.

Configuration
J1: Target reset configuration
Jumper J1 connects the Emulation Adapter reset line and the user target board reset line and is
populated by default. EA also features a Reset push button (SW1).
If having problems establishing the initial debug session with the Emulation Adapter, remove J1
and try again.
J2 and J3: Clock source configuration
Jumpers J2 and J3 select clock source for the emulation device.
Position 1-2 (default position) selects the crystal circuit oscillator on the user target board.Posi-
tion 2-3 selects an external clock source (Q1 socket on the Emulation Adapter).
The Emulation Adapter may not operate when your target board’s crystal circuit is
used as the clock source. Typical design guideline is that the crystal should be as
close as possible to the microcontroller. The crystal on your target board might not os-
cillate in conjunction with the Emulation Adapter when the clock lines (TP21_2,
TP21_3) between the crystal and the emulation device on the Emulation Adapter be-
come too long, thus affecting the impedance of the crystal circuit.
Enclosed in the Emulation Adapter package is a separately packed 16 MHz crystal.
The crystal can be used as a 16MHz external clock (XOSC) source to the emulation
device. If a different clock frequency is required, insert appropriate crystal into the Q1
socket and replace C24 (default 10pF populated) and C25 (default 10pF populated)
accordingly. Crystal socket Q1 is per default not populated (NP).
Crystal socket Q1below:

J4 - J13: Trace port configuration
Soldered jumpers are by default placed to connect ARM
CoreSight 20 connector trace signals to port P18 (J9 – J13). If
P18 on user target board is used for any other purpose than
trace, Emulation Adapter allows changing the trace source to
port P22 (J4 – J8) with relocation of the jumpers.
Soldered jumpers J4-J13 on EA on the image below:
Default position on P18
Optional position on P22

winIDEA configuration
By default, P18 port pins (P18_3 – P18_7) or P22 port pins (P22_0 – P22_4) are set as GPIO
pins. To configure these pins as trace pins in winIDEA, open Hardware menu / CPU Options /
Analyzer tab and add a script CYT2Bx_TraceInit.cpp in the SoC Initialization section. Via the
Parameters options and depending on the user target board configuration allocate:
· TRACE CLOCK Port to PORT 18 (or PORT 22),
· TRACE DATAn PORT to PORT 18 (or PORT 22).
More information in winIDEA Help.

P2: Power supply configuration
Emulation Adapter Power supply is configured via the unshrouded 26-pin 2.54 mm header
(P2).

P2 Signal description
Signal Direction is described from the BlueBox perspective.
By default, all jumpers are set to connect your target power supply to the microcontroller resid-
ing on the Emulation Adapter . Only pins 1-2, 3-4, 7-8, 9-10 and 11-12 must be bridged but for
the convenience and ease of use all jumpers are set, except for pins 5-6 and 25-26.
Pin 26 is the polarizer key preventing incorrect connection of the IEA-PS Power converter, when
being plugged in.
If a different power source is used (e.g. a Standalone operation), remove all jumpers and apply
3V3 or 5V to:
· CVDDA (pin 2),
· CVREFH (pin 4, apply the same voltage as on VDDA),
· CVDDIO_1 (pin 8),
· CVDDIO_2 (pin 10),
· CVDDD (pin 12).
Enclosed Power supply package (Power converter and Power adapter) simply plugs into the P2
header row, providing the necessary power supply for Emulation Adapter operation.
LED D1 indicates, if power is supplied to the Emulation Adapter. Refer to the microcontroller doc-
umentation for more details about power voltage designations.
P3 – P6: Emulation device pinout
P3, P4, P5, P6 pinouts match the pinout of the emulation device (176QFP). Refer to the micro-
controller documentation for pin assignment.
J14 and J15: GND connecting points
J14 and J15 provide grounding points on the EA.

Debug and Trace CoreSight 20 connector pinout
Signal Direction is described from the BlueBox perspective.
Be aware that debug and trace signals from the Emulation adapter superset device are
not connected to the target board. They are exposed only to the connectors on the
Emulation adapter.

Power supply package
A Power supply package, which is delivered with the Emulation Adapter, is required when:
· The Emulation Adapter is used as a standalone device .
· The target board doesn’t provide an accurate supply voltage.
· The target board doesn’t provide sufficient current for the Emulation Adapter operation.
The Power converter can supply either 3.3 V or 5 V. Array of jumpers J0 – J9 select 3.3 V or 5 V
voltage on the P3 connector, which connects to the Emulation Adapter.

P3 connector and J0-J9 jumper correlation table
For example, when J2 is in the 3V3 position, it supplies 3.3 V to pin 6 of the P3 connector. When
J2 is in 5V position, it supplies 5 V to pin 6 of the P3 connector pin.
Be careful not to supply 5 V to the microcontroller power supply pin which has de-
clared maximum voltage 3.3 V! Refer to microcontroller documentation for detailed in-
formation.

Solder parts
In the case of soldering the Solder part manually, it’s highly recommended to prolong the solder
pad E on the outer side (e.g., for 1.5–2 mm) during the PCB design. Note that without this modi-
fication, it’s very difficult to solder the Solder part manually.
