Hello,
nios_buttons_external_connection_export : in std_logic_vector(3 downto 0) := (others => 'X'); -- export nios_leds_external_connection_export : out std_logic_vector(9 downto 0); -- export gpio_0_external_connection_in_port : in std_logic_vector(31 downto 0) := (others => 'X'); -- in_port gpio_0_external_connection_out_port : out std_logic_vector(31 downto 0) -- out_port
);
end component soc_system;
...
u0 : component soc_system port map (...
nios_buttons_external_connection_export => KEY_N, -- nios_buttons_external_connection.export nios_leds_external_connection_export => LEDR, -- nios_leds_external_connection.export gpio_0_external_connection_out_port => GPIO_0(31 downto 0) -- .out_port
);
end;
---------------------------------------------------------------
You do not connect all your component signals with the port map.
And you connect the 4 KEY_N with nios_buttons_external_connection_export
and again KEY_N(0) to the Reset_n
What is the parallel port configuration ? in, out, inout ?
