However when I compared the recommendations to the FX3-DVK-BOARD-DEVICE_REV3 board schematics I noticed that in FX3-DVK-BOARD-DEVICE_REV3 MOSI and MISO Pins are pulled up, while in the recommendations this is not advised. I followed the recomendations on choosing the Flash and did everything according to AN70707 EZ-USB FX3/FX3S Hardware Design Guidelines and Schematic Checklist and according to AN76405-EZ-USB FX3/FX3S boot options. However when I program the Flash, the microcontroller does not appear as a USB device in the operating system (a camera in my case) and I can no longer program the flash nor the RAM. When I program the device RAM, everything works as expected. I am using CYUSB2014-BZXC microcontroller and configured the microcontroller to boot from SPI Flash with usb fallback.
