    you should tell people a little more about your system

    - NIOS VERSION ?

    - QUARTUS VERSION ?

    - DEVELOPMENT BOARD ?

    is sample program running ?

    - CUSTOM BOARD ?

    - do you use external flash ,ram ?

    - is a NIOS sample program running ?

    - is a small testprogram runnning from onchip ram ?

    - does programming works ?

    - does a program from flash works ?

    My tools are:

    quartus4.2+niosII 1.1;stratix1s10 develop board;I make my own hardware image ,download it to stratix fpga, set up a software program,debug it in NIosII IDE.

    use external flash,sram,eternet,sdram and on_chip ram....;data memory and progrm memory is sdram,which base address is 0x0100000.

    In my program the function of printf can't work too.

    you ask that "is a small testprogram runnning from onchip ram ? ".

    I don't know .

    my program dosen't work.the program dosen't work from flash.

    "...I make my own hardware image ..."

    does the board work with a predefined hardware and software

    sample from altera ? could you debug, program such a sample ?

    I only know the cyclone board, but I think it should be the same,

    to check if your problem is perhaps the sdram, try to run

    - your program from sram,

    - a small testprogram fron onchip ram

    check the settings of your cpu in sopc builder.

    - reset address: flash

    - exception address: onchip memory (in my case)

    in system library set program and date memory to

    sram or onchipmemory.
