DK-NIOS-2S60N -- problem with direct JTAG configuration

Hello,  

 

I have a dk-nios-2s60n board (http://www.altera.com/products/devkits/altera/kit-niosii-2s60.html). Board and Stratix ii works fine with factory config. When I try to configure Stratix ii with my own verilog configuration (QII 9.0) via USB-Blaster - then the problem arise: 

 

During the configuration process the LED 4 (Error) is lighting up on the board. After configuration process nothing happens - all LED is dark (except LED 6 (Config_done) and LED 5 (Power)).  

 

I try to load to fpga the following simple code: 

 

 

--- Quote Start ---  

module test(LED); 

 

output LED; 

assign LED=1; 

 

endmodule  

--- Quote End ---  

 

 

In Assignments edition I write: 

 

--- Quote Start ---  

LED Location PIN_W15 Enabled 

--- Quote End ---  

 

 

All unused pins is configured as tri-stated inputs. 

 

Could I load to fpga arbitrary verilog code ? Or DK-NIOS-2S60N is preconfigured to work only with NIOS II ? 

 

Thank you

My bad :) 

 

From DK-NIOS-2S60N reference manual:

When a pin drives logic 0, the corresponding LED turns on.
