Locate the

Elevator Modules

Each elevator module is identifiable

by its four card edge connectors.

Identify the

Elevator Modules

EachelevatormoduleiseitherPrimary

or Secondary. They are identifiable

asfollows:

• PrimaryElevator:

written on inside top and denoted

by white card edge connectors

• SecondaryElevator:

written on inside bottom

Locate Additional

Modules

Gather any additional modules that

will be used to assemble your desired

Tower System configuration.

Identify the Primary and

Secondary Card Edges

Foreachmodule,thewordsPrimaryand

Secondary are written along the card

edges. The primary edge is also denoted

by a white stripe.

Plug in Primary

Card Edge

Match the white stripe on the edge of

each module to any available connector

onthePrimaryElevatorandplugitin.

Attach Secondary

Elevator

With all desired modules connected to

thePrimaryElevator,carefullyattachthe

Secondary Elevator onto to the secondary

card edges of each module.

How to build your Tower

NOTE: First-generation modules

IfusingtherstgenerationofTWR-ELEVmodules,

the board labeled Functional Elevator is equivalent

tothePrimaryElevatorasdescribedinthe

instructionsabove.TheboardlabeledDummy

Elevator is different than the Secondary Elevator,

but will work with most assembled Tower Systems.

Ifusingrst-generationperipheralandMCU/MPU

modules, the white stripe along the outer edge of

the board will not be present.

Step-by-step installation instructions

In this Quick Start Guide, you will learn how to set up the TWR-MCF5441X

module and run the Linux and MQX shell demonstrations.

Assemble the Required

Tower System Modules

TheLinuxandMQXdemonstrationsthat

come pre-installed on the TWR-MCF5441X

requiretheuseoftheTWR-SER2.Please

assemble the TWR-MCF5441X and the

TWR-SER2togetherusingtheTWR-ELEV

asdescribedinthe“Howtobuildyour

Tower”sectionofthisQuickStartGuide.

Connect the

Serial Cable

Attach the header end of the provided

DB9adaptercabletoUART0(J1)ofthe

TWR-MCF5441X.AttachtheDB9end

to a serial cable connected to the host

computer.Openaterminalwindowon

the host computer. Use the appropriate

COMporttoestablishaserialconnection

with the TWR-MCF5441X.

STEP

Usethefollowingconnectionsettings:

Bitspersecond:115200,Databits:8,

Parity:None,Stopbit:1,Flowcontrol:

None.

Connect the

USB Cable

AttachtheprovidedUSBA-to-Mini-B

cablebetweenthehostcomputer(ora

USBwalladapter)andtheMini-B(J9)

receptacle on the TWR-MCF5441X.

TheUSBcablewillsupplypowertothe

TWR-MCF5441X and additional

Tower System modules via the

TWR-ELEV.Theconnectedterminal

window on the host computer should

indicatethatU-Bootinitialization

has started.

STEP

Setting the Default OS

The TWR-MCF5441X comes

preloadedwithaLinuxkernelandabasic

MQXshell.TheLinuxkernelisthedefault

applicationthatU-Bootwillload.

TochangethedefaultOSpressanykey

within the connected terminal window

on the host computer within the first few

secondsofU-Bootinitialization.

The terminal will present the user with a

U-Bootprompt.

SettingthedefaultOStotheMQXshell:

• Type“set bootcmd run mqxboot” and

press “Enter.” Then type “save” and

press “Enter” to save this change to the

U-BootenvironmentvariabletoNAND.

• Presstheresetbutton(SW3)onthe

TWR-MCF5441XtorestartU-Bootand

automaticallyentertheMQXshell.

SettingthedefaultOStotheLinuxkernel:

• Type“set bootcmd run jffs2boot” and

press “Enter.” Then type “save” and

press “Enter” to save this change to the

U-BootenvironmentvariabletoNAND.

• Presstheresetbutton(SW3)onthe

TWR-MCF5441XtorestartU-Bootand

automaticallyentertheLinuxkernel.

Linux Prompt Option

Refer back to Step 4 if required

tosetthedefaultOS.

U-Bootwillinitializeandautomatically

load the preinstalled configuration of

LinuxfromNAND.OncetheLinuxboot

has completed the user is presented

withaLinuxprompt.Atthepromptuse

the “help” command to explore available

commands.
