CY4611 FX2 USB to ATA/CF Reference Design Operating

Instructions

The CY4611 ships as CF+disk(hard drive or CD

drive). Other available options are ATA disk only

(one or two hard drives/CDs) and a standalone

Compact Flash reader.

There are three “getting started” sections below.

They describe how to use the kit as a CF reader,

what to do if you downloaded this from the web, and

how to connect the kit to a disk drive.

Getting Started – CF only

Follow these instructions to use the board as a CF

reader without other drives attached:

Plug the 4611 into any high-power USB port.

Keyboard hubs and other bus-powered hubs are low-

power USB ports. All other USB ports are high-

power.

If this is the first time that this device has been

connected to the computer, the computer will prompt

you for a driver for the device. Use the standard

class driver. A new drive letter will appear. You do

not have to have a CF in the reader to get the drive

letter. CF may be inserted and removed whenever

Windows is not accessing it.

Note: The power workaround used in this design

will not pass compliance testing, and it may cause

data loss in hibernate (S3).

Getting Started – Web downloads

If you downloaded this release from the web and are

not using a new board with a CF socket (4611 rev

C), here are some things you need to know:

• You will have to download the fx2_ata firmware

to your board. See downloading below.

• If you are using a CY3681 development board,

you will need to modify the hardware to enable

ATA operation. See “Using this Design with an

FX2 Development Kit” below for details.

Before you start, you should have the following:

• CY4611 “tailgate” board or CY3681 development

kit (rev C or higher) and standard 80-pin IDE

cable (or 40 pin cable if you are not using

UDMA).

• The 2.20, 2.30 and higher releases require rev E

chips. These releases will NOT work with rev B

or rev D chips. Revision E chips are marked:

CY7C68013-56PVC

E 01xx or 02xx (Date code)

Getting Started with a Disk

If you want to use the design with an ATA device,

like a hard drive or CD-ROM, follow these

instructions:

1. Remove the VBUS jumper (JP2).

2. Turn off your disk drive power supply.

3. Attach the 4-pin power cable to your drive(s) and

to the board.

4. If you are using two drives, adjust the

Master/slave jumpers on your drives so there is

one master and one slave drive.

5. If you are using one drive and a CF, change the

drive jumper to the slave position.

6. If you are using only one drive, either master or

slave will work.

7. Attach the IDE ribbon cable to your drive(s) and

to the 4611 board. An 80-pin cable is required

for UDMA.

8. Turn on the disk drive power supply.

9. Attach the USB cable to a Windows PC.

10. A drive letter will now appear for the CF reader.

11. Install the software from the CD (see software

installation below).

12. Run the cyup_cf_ata program from \cypress\usb\

to download the CF+ATA image. Run the

cyup_ata.exe program to download the non-CF

image.

13. Cycle power on the 4611 and drives. They will

now appear in “my computer”.

Software Installation

The Mass Storage Reference Design Software is an

add-on to the Cypress EZ-USB Development Kit.

Therefore, The EZ-USB Development Kit must be

installed on the system to perform functions such as

building and modifying firmware or re-programming

the EEPROM. The full EZ-USB Development Kit

has been included on the Mass Storage Reference

Design CD. Also, in order to compile the Mass

Storage firmware you must install the full version of

EZ-USB FX2 USB to ATA Reference Design Operating Instructions

the Keil 8051 tools (available from Keil Software at

www.keil.com).

Installation Steps

1. Install the EZ-USB Development Kit by running

setup.exe located in the "FX2 Dev Kit" directory

on the CD.

2. Copy the “FX2_ata” directory and all of its

contents to the c:\cypress\usb directory.

\FX2 Dev Kit\ - Development kit installation

Disconnecting the device

Microsoft recommends that you use the “Eject

Hardware” icon to shut down USB disk drives before

they are unplugged. This prevents potential data

loss.

Converting the demonstration board to a

new Firmware Image

The 4611 board is shipped with the CF firmware

image already programmed in the EEPROM. If

firmware updates are required, plug the device into a

Windows PC and run one of these programs:

• CYUP_ATA.exe – Downloads an image for

ATA-only operation.

• CYUP_CF.exe – Downloads the CF-only

image. This image is the factory default.

• CYUP_CF_ATA.exe – Downloads the

CF+ATA image.

If you have modified the firmware so that a drive

letter will not appear, you must follow this procedure

to update your firmware.

1. Turn off the power.

2. Remove the EEPROM jumper (jp1) from the

board. This will force the device to come up as

an unconfigured FX2 rather than a Mass Storage

device.

3. Keep the power cable connected to the tailgate

board. Disconnect the drive from the tailgate

board. Turn on the power.

4. Plug the board into USB.

5. Install the jumper (JP1) again.

6. Start the Cypress USB Control Panel

“EZMR.exe”.

7. Make sure that the FX2 button is pressed (in the

middle of the toolbar).

8. Press the DOWNLOAD button.

9. Download "examples\fx2\vend_ax\vend_ax.hex".

10. Enter the following settings on the VendReq

toolbar:

Req 0xA9

Value 0x0000

Index 0xBEEF

Length 1

Dir 0-OUT

Hex Bytes FF

11. Press the vendReq button to reprogram the

EEPROM.

12. Cycle power on the tailgate board.

13. Press the EEPROM button.

14. Download the new fx2_ata.iic file to the

EEPROM.

15. Turn off the power and disconnect the device

from USB.

16. Reconnect the board to the drive.

17. Turn on power and connect to USB.

Using this Design with an FX2

Development Kit

Important Notes:

• There are three solder points (SP1, SP2,

and SP3) that must be connected in order to

enable pull-ups and pull-downs needed for

reliable ATA operation.

• Remove JP2

• Connect JP2 pin 2 to VBUS. Connect a 10K

pulldown to this signal.

• Connect JP2 pin 1 to an external 5v power

supply.

• Connect one of the ground points to the

external power supply.

• Cut the key pin (pin 20) on the ATA

connector (P8).

1. Start with the Development Board Disconnected

from USB

2. Attach a short (4” or less) 80 pin ATA cable (or a

40 pin cable is UDMA/66 is not used) to the ATA

connector on the Development Board. Attach the

cable such that pin 1 of the cable is attached to

pin 1 of the ATA connector on the Development

Board.

3. Attach the other end of the cable to the IDE

drive. The connector on the IDE drive should be

keyed for the cable. If not, ensure that pin 1 of

the cable corresponds to pin 1 of the IDE

connector on the drive.

4. Attach the Development Board to the USB 2.0

host controller.

5. Verify that the Development Board has

enumerated successfully. To verify

enumeration, start the EZ-USB control panel and

press the “Get Dev” button to retrieve the Device

Descriptor.

6. Power up the IDE drive/ dev board combination.

7. Download firmware. Download the fx2_ata.hex

firmware using the “Download” button on the EZ-

USB Control Panel.

8. The device should re-enumerate as a mass

storage device. See the section on driver

installation for information on installing device

drivers.

You can also program the EEPROM on the 3681

board to work as a mass storage device without

downloading firmware:

1. Put the EEPROM switches in “EEPROM

enabled” and “Large”

2. Power up the 3681 board and connect it to the

PC.

3. Start the Cypress control panel (ezmr.exe).

4. Click the EEPROM button on the control panel

and download your .iic file.

5. Cycle power on the 3681 board. It should now

come up as a drive.
