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 ?- Mark as New

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).

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.- Mark as New

--- Quote Start --- hi, may i know what do you mean by changing the pins? i dont understand. i am having the same problem with sdram. --- Quote End --- 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 :)
