downloading program to FPGA

Hello everyone,  

I think I have some problem to downloading my program to FPGA. 

I've checked in device manager, I could recognize the both FPGA in my system. 

I've asked already the VHDL program in forum, seems it doesn"t have problem, thus I've checked I assigned the right pin. 

In programmer, I've succeed to downloading the program, progress successful, also when I press start in programmer, I have reaction of LED in USB-blaster II, its LED switch to green, then switch back to blue and on the same time, I could noticed a voltage jump in pin TDI and TCK(clock). 

I've also changed the frequency of Jtag from 24MHz to 6MHz. 

When I downloading the program, it should switch down a LED.  

Power supplier of 3.3V LED FPGA. So my program to put one pin in the mass 

 

 

library ieee; 

use ieee.std_logic_1164.all; 

 

 

 

 

 

 

ENTITY TP2LE IS 

PORT( 

 

 

 

 

s : out std_logic ); 

END TP2LE ; 

 

 

 

 

ARCHITECTURE data_flow OF TP2LE IS 

BEGIN 

s<= '0'; 

 

 

 

 

END data_flow; 

 

This is my program FPGA  

 

 

Then in schematic the compnent TP2LE is directly connected to pin J2 

and I use an Altera max 10 

 

Could anyone help me 

Thank you very much

Have you seen if it makes a difference setting s to '1'? 

it might be easier to debug putting a counter in there to make an LED flash, rather than just try and turn it on. Then at least you'll know the design is loaded

Thank you for your replying 

Yes, Ive checked to set 1, but it still doesn't work and Everything were already solder in the board by my predecessor, so I couldn't modify the circuit anymore
