Try using alt_printf (instead of printf) for printing statements to a
terminal screen if you want a smaller footprint for a Nios project.
This is a lighter-weight version of printf that's optimized for Nios
(also has fewer features, but works fine for my UART interfacing).

Also try checking the "reduced device drivers" and "lightweight device
drivers API" in the project settings.  This should help.  My project
was in Nios IDE 6.1, so I can't speak to the newer toolsets, but this
worked for me.

This message indicates that the linker thinks you've got no memory _at 
all_ for the text section! So memory is not to small, but probably badly 
mapped. I suggest you look at (and compare) the linker configuration and 
SOPC/NIOS configuration.

The error sounds strange, maybe something with 16/32 bit CPU setting? Nios
itself is sometimes strange, too. Do you have changed and recompiled the
setting for the library project, too?

If there is a printf, much of the library will be linked. If you have some
LEDs for a hello world test, it could be much smaller.

If it doesn't work, Altera has a very good support. Once I needed help with
creating some special programming files and scripts for programming a flash
behind a FPGA and they helped to solve the problem. Maybe this is one of
the advantages of paying such high prices for the subscription (but there
is good support for the web edition, too).

Thanks. I change mode from Debug to Release. Although the memory
requirement is smaller (from 40K to 14K), it still has the same error
message.
The program is only a simple Hello_world. It should not be so memory
hungry.
Thanks,

Try release mode. You can switch this somewhere in the project settings in
Eclipse ("Properties" right-click menu item on the project).

I have increased instruction and data on chip memory to 64K. It is
larger than the claimed 40K. Could you help me? Thanks.

Hi,
I am trying to use Nios II with one Stratix II (2S60) DSP board, not
