1.Introduction
This user guide provides instructions to handle the CYTVII-B-H-8M-320-CPU and CYTVII-B-H-320-SO evaluation boards, collectively referred to as 'CPU board' in this document. This is an evaluation platform for the
CYT4BFCC Traveo™ II device. The board can be used as a standalone board for basic validation or in combination with the CYTVII-B-E-BB Traveo II base board (available separately from Cypress). This document
assumes that you will work with the combination (CPU board + base board), and provides guidance on how to
use the features of the evaluation platform.
1.1Precautions and Warnings
The board is a delicate PCB; make sure that the evaluation board is handled by qualified personnel who are
aware of the capabilities of the board. Handle the board carefully and make sure it is not bent or subjected to
stress. Ensure your own safety arising from electrical hazards and other sources.
The CPU board is shipped with a 12 V DC power adapter. This adapter can be plugged into the AC mains
supply anywhere in the world and is designed to receive 100-240 V AC V @ 50/60 Hz. While powering the
board, you must connect only the power adapter supplied with the evaluation board and not any other part.

3.Operation
This section describes the operation of the CPU board and the base board. It is assumed that you
have connected the CPU board to the base board using the Samtec interface and inserted a Traveo
II device into the IC socket (applicable to CYTVII-B-H-320-SO boards only). Follow these steps to
operate the CPU board and the base board:
1. For the socketed CPU board, ensure that the device is inserted into the socket. Remove the four
screws on the socket using the screwdriver provided in the box and open the socket cover. If the
device is not present, place one carefully using a vacuum picker or a pair of tweezers.
2. Ensure that pin 1 of the device is near the pin 1 marking on the PCB, as shown in Figure 3-1.
Also ensure that the device is placed in an angle such that the pins on all four sides of the FBGA
package match well with the socket pins. Align the device slightly, if required.
Figure 3-1. Orientation of Device when Inserted in Socket
3. Replace the socket cover and fix the four screws so that the socket cover tightly sits on the
socket base.
4. A 12 V wall adapter board is supplied along with the CPU board. Connect the 12 V wall adapter
to the barrel connector marked “12V DC” on the CPU board. Connect its plug to a mains socket
using one of the four plug adapters provided in the white box (depending on the geographical
location and the socket type available).
5. Ensure that jumpers J16, J17, J18, J19 (position “1-2”), J14, J20, J21 (current measurement
jumpers) are inserted on the CPU board.
6. Turn on the mains supply to the wall adapter. Turn on the switch SW2 on the CPU board. The
LED labeled PWR should light up.
CYTVII-B-H-8M-320-CPU Evaluation Board User Guide, Document Number: 002-26716 Rev. *A17
Operation
7. Connect an appropriate programming tool to one of the programming interfaces (J13, J4, J12,
J5). Programming tool options are:
❐ Arm ETM MICTOR on J13
❐ Cortex DEBUG on J4
❐ Arm Standard JTAG on J12
❐ Cortex DEBUG and ETM on J5
8. Install the appropriate programming integrated development environment (IDE) on a PC. The
programming IDE (GHS MULTI, IAR Embedded Workbench, Cypress Programmer, etc.) should
be able to detect a device (read the device ID) and to load a firmware HEX file (.srec) into the
device flash successfully.
As part of the release package, various firmware examples compiled in .srec programming IDEs
are available. Some examples use specific transceivers on the base board.
9. To start with, use the LED blink example provided with the release package to test the functioning of the board.
10. Connect a USB-mini cable to J28 and the other end to a PC. Open Tera Term or your preferred
terminal logging application and set the appropriate port and baud rate (typically 115,200 baud,
8, N, 1). Ensure that jumpers J30 and J31 are inserted on the CPU board. Some firmware examples provide data logs from the device or ask for user inputs over the terminal.
