TOWER SYSTEM

Get to Know the TWR-P1025

TWR-P1025

Freescale Tower System

The TWR-P1025 module is part of the Freescale Tower System

portfolio, a modular development platform that enables rapid

prototyping and tool re-use through reconfigurable hardware.

Elevate your design to the next level by building your Tower

System today.

Quick Start Guide

The TWR-P1025 processor module can be operated as a stand-alone

single board computer (SBC) or a Tower System rapid prototyping

development platform. Freescale’s MQX™ real-time OS (shipped

separately) support enables applications to quickly migrate from

Freescale MCUs up to the high-performance QorIQ P1025 processor

featuring networking and industrial connectivity. The P1025 also features

a protocol offload engine which eliminates the need for an external

industrial protocol FPGA/ASIC in the system.

Connect a Display

(Optional)

Purchase and connect the TWR-ELEV

modules and TWR-LCD display module to

see a short video on example applications

included with the TWR-P1025. See

the TWR-LCD quick start guide for

assembly instructions. The SW1 Dip[1:3]

switches should be set to [ON, OFF, ON],

respectively. The remaining dip switches

should be at their default setting.

After applying power, wait one minute for

the video to begin.

Powering

TWR-P1025

Connect the 5-volt @5A power supply to

the 5-volt barrel connector on the TWR-

P1025 module. Note that the heatsink on

the TWR-P1025 can become hot. This is

normal.

Configuring a

Terminal Application

for the Console

On-board circuitry has been provided to

support a host computer console window

over the mini type B USB connector.

Users should note that USB drivers should

be installed onto the host PC before the

serial terminal can be used. These can be

downloaded from ftdichip.com/Drivers/

VCP.htm (FT2232).

Plug in the USB cable between the mini

type B USB connector on the board and

your PC. Do not bend the cable once it

has been inserted. Your PC will assign two

COM port numbers to the USB serial ports

after the driver is installed.

Step-by-Step Installation Instructions

In this quick start guide, you will learn how to set up the TWR-P1025 module and run

the included demonstration software. For more detailed information, please see the

user manual found on the included DVD or at freescale.com/TWR-P1025.

Quick Start Guide

TOWER SYSTEM

Open a serial console using any terminal

emulation application attached to the lower

numbered COM port with the following

serial protocol settings: Bits per Second:

115200, Data Bits: 8, Parity: None, Stop

Bits: 1, Flow Control: None. See the user

manual for more details.

Connecting

Cables

Dual Ethernet and RS485 ports enable

point-to-point networking demos on a

single TWR-P1025 module. Any Ethernet

cable can be connected between the

Ethernet ports and the ports will auto-

configure for proper communication. Auto-

configure also enables a direct connection

from either Ethernet port to a host

computer Ethernet port. All TWR-P1025

headers have pin 1 marked with a white

dot printed on the board and increasing

pin numbers proceeding top to bottom,

right to left from pin 1 while looking into

the header pins.

For cable connections on other interfaces,

refer to the user manual.

Controlling

the Board

Upon power-up, you can also hit any key

on a connected serial terminal to get to

the u-boot prompt, otherwise the board

will boot to the Freescale Linux OS.

You can also log in to the module via

the OpenWRT interface by opening your

browser to 192.168.1.1 (you will need to

connect your PC LAN port to the module’s

Eth0 port and reconfigure your PC IP

address to 198.168.1.54). The OpenWRT

interface will allow for easy configuration

of the module’s network settings. Use the

following information to log in:

Password: root

Standard u-boot and Linux commands are

supported.

Debugger Interface

Connections

When the board is powered off, connect

the desired debugger hardware to the

standard JTAG/COP header connector

J3 lining up pin 1. TWR-P1025 includes

on-board debugging circuitry to support

CodeWarrior software to work with the

board.
