Configuring an FPGA via FX3 CYUSB3014
my design contains an FX3 USB3.0 controller CYUSB3014 and Artix-7 FPGA. I want to configure my FPGA only via USB 3.0 connector. Fortunately, this function is specified in the datasheets on FX3. There is a visual image in datasheet AN84868 "Configuring an FPGA Over USB Using Cypress EZ-USB FX3" on page 2 how to connect FX3 and FPGA for it. Only 5 signals required.
I want to understand what the image is in the Xilinx Impact program when I connect a chain to the USB 3.0 connector through FX3? Whether it is a standard chain of chip FPGA and SPI Flash (in my case)? Or will be further defined FX3 chip? Сan I thus configure Flash too? Or this option only for firmware FPGA?
