In order to download a new image to the I2C EEPROM via control center, you need to change the PMODE pin settings in hardware.
The three PMODE pins PMODE[2:0] should be set to F1F for I2C Boot. In order to load a new image through Control Center, you must change this to USB Boot (F11).
If you reset or power cycle the device now, you will be able to see "Cypress USB Bootloader" in the control centre. Now you can load the image using control centre -> program->FX3->download to EEPROM
Once the image is written, change the PMODE pins back to F1F. Now, a reset or power cycle will boot the new image stored in the EEPROM..
If you are using the FX3 superspeed explorer kit, changing the PMODE from F1F to F11 can be accomplished simply by shorting jumper J4. To change it back to F11, the jumper j4 should be left unconnected.
