Introduction

Quick Start Guide for M53015EVB

In this Quick Start Guide, you will learn how to

setup the Web server on the board and use the

pre-loaded u-boot bootloader to boot the µClinux

kernel with filesystem resident in flash.

In addition, this Quick Start Guide will provide a

walk-through of how to play a sample MP3 from

the USB flash mass storage device included in

the kit, and also record and play back a voice

WAV file from the included SD memory card.

Connect the

Power Connector

Plug the power connector into the barrel

connector (J51) on the board. Power-on

the board via the switch (SW6).

As the board autoboots µClinux, you

will hear the welcome message from the

board in a few seconds, shortly after the

LED (D1) lights up.

Install the USB to Serial Driver, CP210x_

VCP+Win2K_XP_S2K3.exe, found on

the DVD. This will enable the board to

communicate to a serial terminal.

Connect the USB Cable

Connect the USB cable from

the PC to the Serial-to-USB connector

(UART0) on J49.

STEP

Open HyperTerminal

on the PC

Click Start Menu > Programs >

Accessories > Communications >

HyperTerminal.

STEP

Open and Configure

HyperTerminal

Configure for 115200, 8 bits, no flow

control, 1 stop bit.

STEP

Connect an Ethernet

Cable to the Network

If you would like to connect the board via

a local network, connect an Ethernet cable

between the network and the board via

the bottom RJ45 jack. (P2) This Ethernet

interface uses DHCP and will automatically

get an IP address. Skip to Step 8.

To connect directly to a PC, continue to

Step 6.

STEP

If Necessary, Manually

Setup TCP/IP on the PC

The default IP address of the board is

169.254.3.3. Typically, when you connect

your computer directly to the board,

the computer will default to an auto IP

address on the same subnet as the board

(169.254.x.x), requiring no setup.

NOTE: The PC may take a few minutes to default to

the auto IP address and make the connection.

If you have trouble connecting, configure

the IP address of the computer

manually via Start > Settings > Network

Connections > Local Area Connection.

Note your original TCP/IP settings, then

set your IP address to 169.254.3.4 and

your subnet mask to 255.255.0.0.

STEP

Connect an Ethernet

Cable Between

the PC and the Board

Connect an Ethernet cable between

the PC and the board via the top

RJ45 jack (P2).

Quick Start Guide for M53015EVB

STEP

Confirm IP Address

of Board

Now, go to the previously configured

HyperTerminal window. At this point, the

board would have already booted and you

will have to hit “Enter” in order to see the

“$” prompt.

Now, type the command: ifconfig in order

to verify your IP address for eth0, if you

are connected to a local network, or eth1,

if you are connected directly to a PC. The

IP address for eth1 will be 169.254.3.3.

STEP

Open a Web Browser

Next, open a Web browser and

go to the board’s IP address, found in the

previous step, to view the Web page that

resides in the M53015EVB external flash

memory.

This page is being served by the

µClinux Boa server residing in

external flash memory.

STEP

Insert the SD Memory

Device

Insert the included SD memory device

into the board’s SD connector (P1).

You will see µClinux automount the SD

memory device, which is a new feature

added to the standard ColdFire µClinux

distribution. Hit “Enter” to see the

command prompt.

Quick Start Guide for M53015EVB

STEP

Record Your Voice

After the SD memory device has

mounted, it is now ready to use. We will

use the on-board microphone to record

voice with the internal voice codec.

In HyperTerminal, type the command:

vrec -w -t 10 -s 8000 -b 16 -D /dev/

dsp1 /mnt/sd/test.wav. Now, speak

into the microphone for approximately

10 seconds.

Next, type the command: ls /mnt/sd.

You will see the contents listed as:

Next, type the command: vplay -t 10 -s

wav to play the file using the internal

voice codec.

You will hear your voice audio from the

on-board speaker.

STEP

Mount the USB Mass

Storage Device

Before moving on, please move the blue

jumpers J3 and J4 on the board to position

2-3. Moving these jumpers connects the

external codec to the on-board speaker

instead of the internal. For further details

of the internal and external codecs, please

refer to the M53015EVB User’s Manual.

Insert the included USB mass storage

device into the board’s USB Type A

receptacle (J50). You will see the device

automount the USB mass storage device,

which is a new feature added to the

standard ColdFire µClinux distribution.

Hit “Enter” to see the command prompt.
