Wait for the EEPROM File Open dialog to completely disappear (1–2 minutes).To program the EEPROM image, on the C圜onsole - EZUSB Interface, click EEPROM and navigate to and select filename.iic, where filename is the name you have given to your EEPROM image.At this point you should still see the development board enumerate as “Cypress EZ-USB FX2LP - EEPROM Missing” under Windows Device Manager because the first byte in the EEPROM is 0x00 (an invalid signature byte).Click Vend Req to verify that the first byte in the EEPROM is 0x00.

Click Vend Req to blast the first byte in the EEPROM.

On the C圜onsole – EZ-USB Interface’s Vend Req toolbar, use the following to fill in the required fields:.

If the data is all CD, then “Vend Req” cannot read the EEPROM (not a large type such as the 24LC64).

Click Vend Req to verify that the 16 bytes displayed in the data window are NOT CD CD CD.

Req=0xA9 (The 0xA9 vendor request is used to access large EEPROMs that have a dual-byte addressing scheme.)

On the EZ-USB Interface’s Vend Req toolbar, use the following to fill in the required fields:.

By clicking Download, navigate your way to the “Vend_Ax” directory and download Vend_Ax.hex.

Set Switch2 to On (enable EEPROM boot).

At this point you should see the development board enumerate as “Cypress EZ-USB FX2LP - EEPROM Missing” under Windows ® Device Manager.

Connect the USB cable to the development board.

Set Switch1 to Large (select the large EEPROM).

Set Switch2 to Off (disable EEPROM boot).Unplug the USB cable from the development board.These steps will allow you to recover from a corrupt EEPROM and successfully program a new EEPROM image every time. To program the large serial EEPROM on the CY3684 FX2LP development kit board, please use the following sequence (refer to EZ-USB Development Kit User Guide.pdf, included in the kit software). Question: How do you program the serial EEPROMs on the EZ-USB ® FX2/FX2LP ™ development kit board?
