DEVELOPMENT SYSTEM CONTENTS

The E VA L -ADuCM360QSPZ is an evaluation kit for the

ADuCM360 and ADuCM361. This kit features a mini-board

(E VA L-ADuCM360MKZ) and an Analog Devices J-Link OB

emulator (USB-SWD/UART-EMUZ) that connects to a PC

USB port via a USB cable. A comprehensive set of development

tools is included on the DVD.

Figure 2. ADuCM360 Mini-Board Connected to J-Link OB Emulator

The development system contains the following:

•An ADuCM360 mini-board

•An Analog Devices J-Link OB emulator

•1 USB cable

•A DVD.

EVALUATION BOARD

The E VA L -ADuCM360MKZ mini-board facilitates

performance evaluation of the device with a minimum of

external components. The board schematic is available after

installation of the software in the documentation folder.

By default, this is

\ADuCMxxxV1.3\Documentation\ADuCM360\Evaluation

Board\Eval-ADuCM360MKZ.

J-LINK OB EMULATOR

The J-Link OB emulator provides nonintrusive emulation via a

serial wire, and also provides supply and UART communication

with the ADuCM360 mini-board. Figure 3 shows a top view of

the emulator board. J2 connector plugs into the ADuCM360

mini board. The J2 connector pinout is shown in Figure 4.

Figure 3. Emulator Top View

Figure 4. J2 Connector

For downloading and debugging, LK1, LK2, LK4, and LK6 must

be inserted. LK3 and LK5 are required to communicate via

UA RT. Required software for the J-Link OB is included in the

software installation.

Note that the J-Link OB emulator replaces the J-Link Lite and

related interface boards previously shipped with the ADuCM360

development system.

CONNECTING THE HARDWARE

Software

J-Link software and documentation pack

includes USB drivers for the emulator, J-Link

Commander, J-Mem, and so on

CM3WSD This utility accepts a hex file and allows it to

be downloaded via the USB interface to the

ADuCM360 device on your evaluation board

Elves Elves.exe is an application that helps a

C programmer choose appropriate functions

from Analog Devices libraries and simplifies

deciding which values to place in the

function parameters.

SOFTWARE INSTALLATION INSTRUCTIONS

Perform the steps described in this section before plugging any

of the USB devices into the PC.

1. Close all open applications.

2. Insert the development system DVD into your DVD drive.

Optionally, download the ADuCMxxxV1.3 folder from

the FTP and save it to your machine using the same folder

structure as on the FTP site. To reduce the download time,

consider excluding either the IAR or Keil folders

depending on which development environment you chose

to use.

3. Double-click on ADuCMxxxV1.3.exe and follow the on-

screen instructions. A menu displays installation options as

shown in Figure 5.

Figure 5. Installation Options

You can choose to install Keil and/or IAR tools as part of

the installation, or at later stage by launching

•mdk470.exe to install this version of Keil µVision.

•EWARM-CD-6502.exe to install this version of the

IAR Embedded Workbench. The IAR Embedded

Workbench requires registering on the IAR website

to obtain a free license key.

The Segger J-link software is selected by default in the

installation menu. It is advised to leave it selected. This

automatically installs the J-Link serial port driver (keep

the default settings that appear in the next Segger messages

windows).

However, if you decide to unselect the Segger J-Link

Software install, and install it at a later stage, you will, at

that time, need to run the Setup_JLinkARM_V459d.exe

located under ADuCMxxxV1.3\Segger. Then, select

Install J-Link Serial Port Driver as shown in Figure 6.

Alternatively, you can run JLinkCDCInstaller_V1.2b.exe

located under ADuCMxxxV1.3\Segger.

Figure 6. Installing Link Software

Although the development system, the IAR Embedded

Workbench®, and the Keil™ software can be installed onto any

hard drive and into any directory, for the purposes of simplicity,

this user guide assumes it is installed at the default location

of C:\ADuCMxxxV1.3, C:\Program Files and C:\keil. In

addition, the Keil tools are automatically installed under an

ARM directory and are fully compatible with µVision3 or tools

for 8051.

If you choose the IAR tools, these will be installed

by default into \Program Files\IAR Systems\Embedded

Workbench 6.5.

PROGRAMS INSTALLED

The software described in this section has now been copied or

installed.

CM3WSD.exe

The folder \ADuCMxxxV1.3\Software Tools\CM3WSD

provides an executable called CM3WSD.exe. This software

accepts a hex file and allows it to be downloaded via the USB

interface to the ADuCM360 device on your evaluation board.

You may want to add a shortcut link for this executable to your

desktop.

elves.exe

The \ADuCMxxxV1.3\Software Tools\Elves folder contains

the elves.exe files. These files are useful tools that accompany

the software function libraries in

\ADuCMxxxV1.3\Code\ADuCM360\common. Again, no

installation is required here, but you may want to add a shortcut

link for this executable to your desktop.

Driver

The J-Link OB emulator requires a driver, which is installed

automatically when the Segger J-Link Software is selected (see

Step 3 of the Software Installation Instructions section). At this

point, check that the driver is installed correctly.

Plug in the emulator and check the device manager (see

Figure 7).

Check that it appears in the Windows Device Manager in both

the communications port and the USB controllers lists.

Figure 7. Device Manager

The J-Link OB emulator drivers JLinkCDCInstaller_V1.2b.exe

can be installed from the ADuCMxxxV1.3\Segger folder, if

J-Link does not appear in the device manager as shown in

Figure 7.

Note that the drivers for J-Link Lite and interface boards

previously shipped in the ADuCM360 development system are

available online.
