Preloaded FPGA Bitstream (FPGA image, SPI Flash)
TE0320 comes with SPI Flash preloaded with a reference design?
Those preloaded image is just for getting started demo, for real designs:
it is expected that these image could be replaced by the customer;
it is expected that these image could be used by the customer as starting point.
