How to simulate Nios II program with SOPC Builder

Altera_Forum · ‎01-09-2012

Hi everyone,

I have an SOPC builder Avalon system with a NIOS-II processor. I want to simulate the whole thing with a program runnin in the NIOS-II. The program itself is very basic, a "hello world" message sent to the UART and some I/O operations.

I have instantiated an onchip-memory in the SOPC. I have modified the linker script using the BSP editor tool to make the gcc compiler link the program to the address of the on-chip memory.

But now I'm stuck, I can't find how to tell SOPC builder to use the hello_world.elf binary to initialize the content of the on-chip memory.

What am I missing or what am I doing wrong?

Thanks

You could have a look on the AN351.

Thanks, but I use SOPC Builder (PCI core is not available with QSYS).

I'll take a look but AFAIK, a lot of things don't apply.

Try to find an older release. I found one here http://www.scribd.com/doc/36117105/an-351

The old NIOS doc is available here : http://www.altera.com/literature/lit-nio2.jsp
