Thank you again, if i understood clearly what you are saying, the only thing that i need to change is the Eprom pin assignement.
my I90_x9card.vhd (no change)
Code:
library IEEE;
use IEEE.std_logic_1164.all; -- defines std_logic types
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;
use work.IDROMConst.all;
package i90_x9card is
-- 7I90 x9 card specific info
constant ClockHigh: integer := ClockHigh90;
constant ClockMed: integer := ClockMed90;
constant ClockLow: integer := ClockLow90;
constant BoardNameLow : std_Logic_Vector(31 downto 0) := BoardNameMESA;
constant BoardNameHigh : std_Logic_Vector(31 downto 0) := BoardName7I90;
constant FPGASize: integer := 9;
constant FPGAPins: integer := 144;
constant IOPorts: integer := 3;
constant IOWidth: integer := 72;
constant PortWidth: integer := 24;
constant LIOWidth: integer := 6;
constant LEDCount: integer := 2;
constant SepClocks: boolean := true;
constant OneWS: boolean := false;
end package i90_x9card;
Now 7i90spi.ucf i need to declare my eprom
but there is 2 spi ports on the 7i90spi.ucf :
Code:
NET "COM_SPICLK" LOC ="P55" | IOSTANDARD = LVTTL;
NET "COM_SPIIN" LOC ="P56" | IOSTANDARD = LVTTL;
NET "COM_SPIOUT" LOC ="P57" | IOSTANDARD = LVTTL | DRIVE = 4 | SLEW = FAST ;
NET "COM_SPICS" LOC ="P58" | IOSTANDARD = LVTTL;
Code:
NET "SPICS" LOC ="P38" | IOSTANDARD = LVTTL | DRIVE = 4 | SLEW = SLOW ;
NET "SPIIN" LOC ="P65" | IOSTANDARD = LVTTL;
NET "SPIOUT" LOC ="P64" | IOSTANDARD = LVTTL | DRIVE = 4 | SLEW = SLOW ;
NET "SPICLK" LOC ="P70" | IOSTANDARD = LVTTL | DRIVE = 4 | SLEW = SLOW ;
Which one is for the eprom and which one for the raspberry ?
Is it for the JTAG tool ?
Code:
#NET "FPGATMS" LOC ="P107" ;
#NET "FPGATDI" LOC ="P110" ;
#NET "FPGATDO" LOC ="P106" ;
#NET "FPGACLK" LOC ="P109" ;
