I was able to make my own custom FPGA shield for an ARM Cortex M3 board (arduino footprint ofcourse!). I used the PapilioOne as reference for basic board design. There is no FT2232 on the board.
I have been able to program the SRAM of the XC3S250E without any problem with my Digilent Adept Tool (JTAG-SPI Full Speed Cable). But unfortunately for me, my Serial Flash SPI based isn't working. I am using a M25P40 device which is supposed to be Xilinx Impact Compatible. Any Solutions ?
I have been trying to generate a PROM file for the SPI using Impact and then create a SVF file using my generated bit file (Indirect Programming) . But nothing happens. Any clues on what might i be doing wrong ?
I am attaching the board sch and brd files. I have divided my FPGA shield into two boards Top and Bottom, the top has the Break-out-board of the XC3s250E and some peripherals. The bottom does all the power supply and provides frequency to the top board and ofcourse attaches to the arduino footprint at the bottom. All this because i made all these PCBs (except the break-out-board) using the toner transfer method. I am attaching the sch and brd files of the top board and also a couple of images of the whole thing.
