INTERFACES

This chapter provides the setup procedures for both the Blackfin
USB-LAN EZ-Extender and EZ-KIT Lite (ADSP-BF533, ADSP-BF537
or ADSP-BF561) and describes each of the interfaces the extender
supports.

The information is presented in the following order.

• “USB-LAN EZ-Extender Setup” on page 1-1

• “USB 2.0 Interface” on page 1-3

• “Ethernet Interface” on page 1-4

• “Optional ADSP-BF537 EZ-KIT Lite Interfaces” on page 1-5

USB-LAN EZ-Extender Setup

It is very important to set up all components of the system containing the
USB-LAN EZ-Extender before applying power to that system. The fol­lowing procedure is recommended for the correct setup.

Power your system when these steps are completed:

1. Read the applicable design interface section in this chapter—the
text provides an overview of the capabilities of the interface.

2. Read “System Architecture” on page 2-2 to understand the physical
connections of the extension board. For detailed information, refer
to “USB-LAN EZ-Extender Schematic” on page B-1.

Blackfin USB-LAN EZ-Extender 1-1

USB-LAN EZ-Extender Setup

3. Remove any rubber feet that may be attached to the EZ-KIT Lite.
In place of these rubber feet, install the four nylon feet and screws
provided with the USB-LAN EZ-Extender. Install the nylon feet in
the mounting holes of the EZ-KIT Lite’s printed circuit board
(PCB). Flip the EZ-KIT Lite upside down so that the three expan­sion headers (

J1—3) are facing up.

4. Set the switches and jumpers on the USB-LAN EZ-Extender
board. Use the block diagram in Figure 2-1 on page 2-2 in con­junction with “Jumper Settings” on page 2-3 and “Switch Settings”

on page 2-6.

5. Set the switches and jumpers on EZ-KIT Lite board. If not already,
familiarize yourself with the documentation and schematics of the
EZ-KIT Lite (see “Product Information”). Compare the expansion
interface signals of the USB-LAN EZ-Extender board with the sig­nals of the EZ-KIT Lite board to ensure there is no contention. For
example, it may be necessary to disable other devices connected to
the expansion interface of the processor and disable the push but­tons on the EZ-KIT Lite.

6. Install the USB-LAN EZ-Extender on the EZ-KIT Lite via the
three-connector expansion interface.

7. Configure any other interfacing boards, for example, another
EZ-Extender board.

USB 2.0 Interface

The USB-LAN EZ-Extender allows you to connect a USB 2.0 chip to a
Blackfin processor without any other programmable logic required. PLX’s
(formerly Netchip) Net2272 device ties directly to the asynchronous
memory bank 3 of the Blackfin processor. You can read from and write to
the USB 2.0 controller by directly addressing the named memory bank.

You can reset the Net2272 processor by asserting LOW these flag pins: PF11
on the ADSP-BF533 processor, PF6 on the ADSP-BF537 processor, and

PF11 on the ADSP-BF561 processor.

The flag pins can be used for push buttons or LEDs on the respective
EZ-KIT Lite; consequently, the user must make the proper changes to
that EZ-KIT Lite. The switch settings required for each of the respective
EZ-KIT Lites are described in the USB Software Readme.txt file in the

...

\Blackfin\Examples\USB-LAN EZ-EXTENDER\USB subdirectory of the

VisualDSP++ installation directory. The readme file describes the USB
software, source code, drivers, and explains how to run a USB-based
application.

Blackfin USB-LAN EZ-Extender 1-3

For correct switch settings, refer to the schematics drawing of the
respective device.

Ethernet Interface

The USB IRQ line of the extender connects to

PF10 on the

ADSP-BF533/ADSP-BF561 processors and PF7 on the ADSP-BF537 pro­cessors. The flag pins can be used for push buttons or LEDs on the
respective EZ-KIT Lites; consequently, the user must make the proper
changes to that EZ-KIT Lite.

When writing to and reading from the USB device using the EZ-KIT
Lites, use memory addresses from Table 1-1.

ADSP-BF561 EZ-KIT Lite 0x2C00 0000 0x2C00 007F

Ethernet Interface

The USB-LAN EZ-Extender allows you to connect a 10/100 Mbps Ether­net chip to a Blackfin processor. SMSC’s LAN91C111 device ties directly
to the asynchronous memory bank 3 of the Blackfin processor. You can
read from and write to the Ethernet controller by directly addressing the
named memory bank.

You can reset the Ethernet processor by asserting the board reset on the
ADSP-BF533 and ADSP-BF561 EZ-KIT Lites. The reset connects to a
supervisory reset circuit managed by the Analog Devices ADM708 IC
device. ADM708 also asserts a reset to the Ethernet chip at power-up.

The Ethernet IRQ line connects to the
processor and

PF9 of the ADSP-BF561 processor. The flag pins may be

Optional ADSP-BF537 EZ-KIT Lite Interfaces

Optional ADSP-BF537 EZ-KIT Lite interfaces are:

• “Power-Over-Ethernet”

• “MII Interface”

Power-Over-Ethernet

The Blackfin USB-LAN EZ-Extender, when used in conjunction with the
ADSP-BF537 EZ-KIT Lite, allows a user to power both the EZ-KIT Lite
and the extender via a 10/100 Mbps switch or a Midspan device that sup­ports IEEE802.3.AF.

Blackfin USB-LAN EZ-Extender 1-5

Optional ADSP-BF537 EZ-KIT Lite Interfaces

The EZ-KIT Lite and extender must not be powered via the 7.5V supply
when in Power-over-Ethernet (PoE) mode. A user can make the appropri­ate jumper changes to the EZ-KIT Lite and extender and then connect the
kit to the extender to power both boards via the switch or Midspan device.
The user must use a switch or Midspan device that supports power via the
data pairs. If a user uses a Midspan device that powers only over the spare
pins, then the PoE circuitry will not work.

Table 1-3 shows a recommended Midspan device that supports both

power over the spare pins and power over the data pairs.
Table 1-3. Midspan Device

Power Sourcing Equipment Manufacturer Part Number

Midspan device PowerDsine 6 PD-8006/AC

Use the Ethernet connector on the EZ-KIT Lite for the PoE application.
Power-over-Ethernet does not work properly if the Ethernet connector is
used on the extender board. When in PoE mode, the blinking LEDs
(

LED1–6]) confirm successful power-up. Since PoE is intended as a simple

demonstration of the power circuitry, you are not able to bring up a Visu­alDSP ++ session while in the PoE mode.

Refer to “Power Select Jumper (JP1)” on page 2-4 for the extender’s PoE
settings. Refer to the ADSP-BF537 EZ-KIT Lite Evaluation System Manual
for the EZ-KIT Lite’s PoE settings.

MII Interface

The Media Independent Interface (MII) allows you to evaluate different
PHY devices with the ADSP-BF537 EZ-KIT Lite. A separately purchased
PHY evaluation board connects directly to the USB-LAN EZ-Extender.
You also need to purchase the J2 connector and solder it to be able to con­nect the two boards together. The part numbers of the SMSC’s evaluation
boards and

Power-over-Ethernet JP1.2 and JP1.3

JP1.1 and JP1.2

When using an ADSP-BF533 or ADSP-BF561 EZ-KIT Lite, you must
not place any jumpers on JP1. Placing a jumper on JP1 can damage the
extender card and/or the EZ-KIT Lite. You must power the
ADSP-BF533/ADSP-BF561 EZ-KIT Lite and USB-LAN EZ-Extender
with the 7.5V power supply provided with the EZ-KIT Lite.

When using an ADSP-BF537 EZ-KIT Lite with the Power-over-Ethernet
feature, you must place a jumper between JP1 pin 2 and JP1 pin 3. You
must power both the EZ-KIT Lite and USB-LAN EZ-Extender with the
CAT5E Ethernet cable, which provides power over the signal pairs. The
Ethernet cable must be plugged into the Ethernet connector of the
ADSP-BF537 EZ-KIT Lite, but not the USB-LAN EZ-Extender. Use the

7.5V power supply provided with the EZ-KIT Lite.
When using an ADSP-BF537 EZ-KIT Lite without the

Power-over-Ethernet, you must not place any jumpers on

JP1. You must

power both the EZ-KIT Lite and extender with the 7.5V power supply

ADDR Enable Switch (SW1.1)

The address enable switch, SW1.1, is used to control the output of the
Blackfin address bus buffer (see Table 2-4). By default, the switch is set to

ON . When SW1.1 is OFF, you cannot communicate to the USB or the

2-6 Blackfin USB-LAN EZ-Extender Manual

USB-LAN EZ-Extender Hardware Reference

Ethernet processor. The address enable switch adds flexibility to the pro­cessors because you can turn the switch

OFF when capacitive loading is an

issue present with other peripherals on the EZ-KIT Lite.

FLAGS Enable Switch (SW1.2)

The flags enable switch, SW1.2, is used to control the output of the Black­fin flags multiplexer (see Table 2-5). By default, the SW1.2 switch is set to

ON. When SW1.2 is OFF, you cannot communicate to the USB or Ethernet

processor. The flags enable switch adds flexibility to the extender—when
the switch is OFF, the flags can be used for other peripherals of the
EZ-KIT Lite.

FLAGS (U12) enabled ON (default)
Blackfin FL AG S (

U12) disabled OFF

USB IRQ Enable Switch (SW1.3)

The USB IRQ enable switch, SW1.3, is used to control the connection
between the Netchip 2272 IRQ line and respective flag pin on the Black­fin processor (see Table 2-6). The switch connects the USB_IRQ line
with PF10 on the ADSP-BF533/ADSP-BF561 processors, and PF7 on the
ADSP-BF537 processor. By default, the USB IRQ enable switch is

ON.

Switch Settings

When

SW1.3 is OFF, communication with the USB processor cannot be

established. The SW1.3 adds flexibility to the extender—when the switch is

OFF, the flag can be used for other peripherals of the EZ-KIT Lite.

Functionality SW1.3 Setting
USB IRQ enabled ON (default)

USB IRQ disabled OFF

Test Mode Enable Switch (SW1.4)

The test mode enable switch, SW1.4, is an internal test pin and should not
be used (see Table 2-7). By default SW1.4 is OFF.

Table 2-7. SW1.4 Settings

Functionality SW1.4 Setting

Test mode enabled ON

Test mode disabled OFF (default)

Serial ROM Enable Switch (SW2.1)

The serial ROM enable switch, SW2.1, is used to control the connection
between the LAN91C111 Ethernet processor and its serial ROM (U3) (see

Table 2-8). When the switch is disabled, the Ethernet processor loads its

Media Access Control (MAC) address from the serial ROM. By default

SW2.1 is OFF. When the switch is ON, you cannot communicate with the

provided Ethernet application code. The switch adds flexibility to the
extender—you can modify the application code and generate another
MAC address when SW2.1 is ON.

IOS[2:0] Switch (SW2.2, SW2.3, SW2.4)

The IOS[2:0] bits on the USB-LAN EZ-Extender are connected directly
to the IOS[2:0] pins of the LAN91C111 Ethernet processor. By default,
the switches are OFF. The IOS[2:0] pins are used in conjunction with the

“Serial ROM Enable Switch (SW2.1)” to select between predefined

EEPROM configurations. For more information about the switches, refer
to the SMSC LAN91C111 data sheet.

Product Overview

Development tools provide easier and more robust methods for engineers to develop and optimize DSP
systems and shorten product development cycles for faster time-to-market. The Development Tools
components include:

Evaluation Kits

● EZ-KIT Lite®

Desktop evaluation board includes an evaluation suite of VisualDSP++® development environment. The
evaluation suite of VisualDSP++ has limited memory only.

● EZ-Extender®

EZ-Extender daughter boards give developers access and ability to connect various peripherals from
Analog Devices and third parties to the expansion interface of the EZ-KIT Lite evaluation kits.

Software

● VisualDSP++®

Software development environment includes a C++ compiler, assembler, and linker, enhanced user
interface, advanced plotting tools and statistical profiling to easily identify programming bottlenecks.

● VisualAudio® Designer

Works in conjunction with VisualDSP++ integrated software development and debugging environment
and includes a variety of ready-to-use software building blocks required for audio system design and
development and provides the ability to generate product-ready code (optimized for memory and MIPS
usage). Supports ADSP-BF533 and ADSP-BF537 Blackfin Processors and the ADSP-21262, ADSP­21364 and ADSP-21369 SHARC Processors.

● Starter Kit

Provides everything needed to get started on an application. Starter Kits contain a Blackfin EZ-KIT Lite,
EZ-Extender daughter board(s), and the Software Development Kit (SDK) which contains sample code,
"how to" documents, and various encoders/decoders that make getting started on an application easy
and shorten the learning curve.

Emulators

● Rapid on-chip debugging allows developers to load code, set breakpoints, and observe variables,
