Error (10802)

Hi

When I try to compile I have this:

Error (10802): VHDL Unconstrained Array error at ide_sd.vhd(7): formal "ID_INIT_FILE" must be constrained

Need some help please:confused:

The code :

library ieee;

use ieee.std_logic_1164.all;

use ieee.numeric_std.all;

-- the ocide controller uses unsigned from here

--use ieee.std_logic_arith.unsigned;

entity ide_sd is

generic

(

-- when emulating devices accessed using lba mode

-- - use the *default* values

lba_mode : boolean := true;

cylinder_bits : integer := 16;

head_bits : integer := 4;

sector_bits : integer := 8;

id_init_file : string

);

port
