programming the sopc builder

Hello,

I am new to the nios and sopc builder.

I tried to build my own nios sopc system from the scratch and i am successful in doing since i did not had any compilation errors and assigned the pins based on the de2 pin assignments.

When I tried to run the Hello World program... I couldn't see the output on the console.

I did program the board using the Quartus.

Just let me know whether i need to configure anything.

Thanks

    does your memory work correct.

    have you checked clock is in the SOPC builder?

    you should try to put reset signal.

    those are things coming up in my head.

    Hello,

    I tried to assign three clocks for my project.

    external clock

    nios clock -- 50Mhz

    sdram clock --50Mhz

    audio_xclk-- 12.88Mhz

    The memory everything worked fine when i compiled the schematic which i get after designing the sopc builder.

    I just don't know where the issues are.

    Coming to the reset signal, I did assign a key on the de2 board for the reset signal.
