If the data is all CD, then it cannot read the EEPROM (not a small type such as the 24LC00). Req=0xA2 (the 0xA2 vendor request is used to access small EEPROMs that have a single-byte addressing scheme)ДЎ0) Press the 'Vend Req' button to verify that the 16 bytes displayed in the data window are NOT CD CD CD. These steps will allow you to recover from a corrupt EEPROM and successfully hand program a small EEPROM every time.ДЈ) Set Switch1 to Small (Select the small EEPROM)Д¦) Set Switch2 to On (enable EEPROM boot)

To program the small serial EEPROM on the CY3681 FX2 Development Kit board, please use the following sequence (Refer to the 'FX2 Getting Started.pdf' file, included in the kit software, section 5.4 for switch context). The steps for programming the Large EEPROM on the CY4611 FX2 ATA reference design board are the same as above, except that you should ignore the Switch1 instructions and substitute the JP1 jumper for Switch2. iic file.Дў1) If the EEPROM was programmed correctly, then plug out the board, set switch2 to On and switch1 to Large and your board should load and enumerate with your firmware.

Otherwise, continue.ДЎ1) On the EZ-USB Control Panel's 'Vend Req' Toolbar, use the following to fill in the required fields:ДЎ2) Press the 'Vend Req' button to blast the first byte in the EEPROM.ДЎ3) On the EZ-USB Control Panel's 'Vend Req' Toolbar, use the following to fill in the required fields:ДЎ4) Press 'Vend Req' to verify that the first byte in the EEPROM is 0x00ДЎ5) Unplug the USB cable from the development boardДЎ6) Connect the USB cable to the development boardДЎ7) At this point you should still see the development board enumerate as 'Cypress EZ-USB FX2 (68613) - EEPROM Missing' under Windows Device Manager because the first byte in the EEPROM is 0x00 (an invalid signature byte).ДЎ8) To program the EEPROM image, on the EZ-USB Control Panel, press the 'EEPROM' button and navigate to and select filename.iic, where filename is the name you have given to your EEPROM imageДЎ9) Wait for the EEPROM file open dialog to completely disappear (1-2 minutes)Дў0) To verify the EEPROM load, repeat steps 9) and 10) above to read the EEPROM and verify that the first eight bytes contain a sequence starting with 0xC2 and followed in reverse endian by either our default VID/PID/DID, or your own if you used the VID and PID parameters in the hex2bix utility when you created your. If the data is all CD, then it cannot read the EEPROM (Not a large type such as the 24LC64). Req=0xA9 (The 0xA9 vendor request is used to access large EEPROMs that have a dual-byte addressing scheme)ДЎ0) Press the 'Vend Req' button to verify that the 16 bytes displayed in the data window are NOT CD CD CD.
