Verify failed between address 0x2000000 and 0x200FFFF

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

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, may i know what do you mean by changing the pins? i dont understand. i am having the same problem with sdram.

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 :)
