Shanjit Singh Posted March 30, 2013 Report Share Posted March 30, 2013 Hi I have used the Papilio and have implemented a few basic digital designs on it. I am planning to make a FPGA shield (XC3S250E) for an arduino footprint (based on an ARM Stellaris Cortex M3 processor). I have a doubt on how the onboard Flash of the Papilio is programmed. The FT2232 (USB-Serial/JTAG) is connected directly to the FPGA pins and unless there is some sort of a bootloader already burned onto the board, there shouldn't be anyway the SPI Flash gets initialized and stores any value. Am i correct on this ? How is the onboard flash implemented ? Thanks Link to comment Share on other sites More sharing options...
