Freescale Tower System

The TWR-MPC8309 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 with this industrial power

house by building your Tower System today.

Quick Start Guide

NET-P23345-TWR-MPC8309-o1v6.indd 2 11/4/11 5:19 PM

The TWR-MPC8309 processor module can be operated as a stand-alone

single board computer (SBC), a primary elevator connected system-

on-module (SoM) or a Tower System rapid prototyping development

platform. Freescale’s MQX™ software support enables applications

to quickly migrate from Freescale microcontrollers up to the high-

performance MPC8309 processor featuring industrial connectivity and

a protocol off-load engine which eliminates the need for an external

industrial protocol FPGA/ASIC in the system.

Connect a Display

(optional)

Purchase the MPC830x-TLCD display

module to remove the need for a host

computer. The display is driven with a

16-bit big-endian parallel interface.

Powering

TWR-MPC8309

Connect the USB2 Full-Speed port to host

computer USB port(s) using the provided

USB cable to power the board, which also

establishes a console connection to the

host. Alternatively, power can be supplied

over the USB2 High-Speed port or the

TWR-ELEV connection. Finally, a power

adaptor (not included) can supply power

over the 5-volt ( ) jack.

Configuring a

Terminal Application

for the Console

On-board circuitry has been provided to

support a host computer console window

over the USB2 Full-Speed port. Upon

power-up, the host computer should

recognize new hardware named TWR-

MPC8309_VirtualCOM, which should

be configured with the TWR-MPC8309_

VirtualCOM.INF driver included on the

DVD or available at freescale.com/TWR-

MPC8309. Once the virtual COM port is

configured, display the console using any

terminal emulation application attached

to the 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.

Step-by-Step Installation Instructions

In this quick start guide, you will learn how to set up the TWR-MPC8309 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-MPC8309.

Informational Demo

Upon power-up, the board automatically

boots the Freescale Linux OS running

an informational demo showing a JPEG

slideshow on a connected display or text

files in the host computer console window.

See the user manual for details on how to

modify the demo contents.

Entering the Boot

Configuration and

Diagnostic Menus

The booting behavior can be changed by

entering the boot configuration menus.

With a host computer connected to the

USB2 Full-Speed port (see step 3), hold

down any key on the host computer while

the board is booting. Select the desired

boot configuration using the menus in the

console window. Diagnostic routines have

been included to verify the functionality of

the board and can be run using the “diag”

command in U-Boot. See the user manual

for details.

Connecting

Cables

Dual Ethernet and RS485 ports enable

point-to-point networking demos on

a single TWR-MPC8309 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. An RS485

loopback cable has been included which

can be connected between the two

RS485 headers. Line up pin 1 marked

with an arrow on the cable connector to

the header pin 1 on both RS485 ports.

All TWR-MPC8309 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.

Debugger Interface

Connections

Connect the desired debugger hardware

to the standard JTAG/COP header lining

up pin 1 with the OBSEL configure

switch setting in the OFF position. TWR-

MPC8309 includes on-board debugging

circuitry to support an OSJTAG debugger

library. To use OSJTAG connect the host

computer to the USB2 Full-Speed port

and set the OBSEL configure switch

setting to the ON position.

Switch Settings
