this can be due to a lot of reasons. 

if you use sdram f.e. check the phase of the sdram clock. 

have you tried a simple hello world with a minimal system running from internal memories instead of external memory ?

Hi, 

 

I had exactly the same problem. Now I tried building a simple project with the simple "Hello_world" code, using only on-chip memory, which should be enough but I get an error message: 

 

make -s all includes  

Linking simple.elf... 

/cygdrive/c/altera/91/nios2eds/bin/nios2-gnutools/H-i686-pc-cygwin/bin/../lib/gcc/nios2-elf/3.4.6/../../../../nios2-elf/bin/ld: region onchip_memory2_0 is full (simple.elf section .text). Region needs to be 25408 bytes larger.

What is the problem? I'm using a Cyclone III board of version 7.2 while using Quartus 9.1. Could that be the problem?

Memory is too small... 

 

Region needs to be 25408 bytes larger. 

 

printf/scanf, etc. are quite large.

I had the same problem. 

 

I was using DE2 board, and the problem was with sdram pins. I had to change manually DRAM_BA pins and DRAM_DQM pins. After that fix, the proyect works properly.

Hi. 

 

You need change in Pin Planner: 

 

DRAM_LDQM to DRAM_DQM[0] 

DRAM_UDQM to DRAM_DQM[1] 

 

and 

 

DRAM_BA_0 to DRAM_BA[0] 

DRAM_BA_1 to DRAM_BA[1] 

 

 

And then, you can assign these pins to your Nios II as buses. 

 

DRAM_DQM[1..0] 

DRAM_BA[1..0] 

 

You must do this because Nios II in SOPC Builder 9.1 SP2 has buses for these connections to the SDRAM  

 

I hope to be clear enough :)
