Clock on CFI Flash Memory

sorry for the question.

Are you sure that is possible use the flash memory without sopc builder?

I try to use it but in data out pin i read nothing.

I've created an entity

entity nuovoflash is

port (

resetgenerale: in std_logic;

clock: in std_logic;

address : out STD_LOGIC_vector (21 downto 0);

data : INout STD_LOGIC_vector (7 downto 0);

ingressi: buffer std_logic_vector (7 downto 0);

uscite : out std_logic_vector (7 downto 0);

chipenable : out STD_LOGIC;

outputenable :out std_logic ;

reset : out STD_LOGIC;

writeenable : out STD_LOGIC

);

end nuovoflash;

The output pins are controlled by a fsm controller.

In the modelsim simulation the signals are good.

The memory should work but it doesn't work.

I've also created an interface entity to separate the data inout in data in and data out but i don't read the output bit from the oscilloscope when i connect the board to it.
