Hi,
I have a CYUSB3014 board without EEPROM and SPI-FLASH, so that I need load firmware when board is power on every time. Can CYUSB3014 load firmware to inner ROM or inner Flash ? And how could I do it? Thank you very much!
best regards,
Tomsen

You can do a RAM download of the firmware. There is no internal FLASH present in FX3. Go through this application note (http://www.cypress.com/documentation/application-notes/an76405-ez-usb-fx3-boot-options).

If you want to download the firmware every time the device power is turned ON, you can download firmware via a USB host on to the RAM.
