DE3 DDR2 demo does not work with Quartus v9.1

Hello,

i used the ddr2-rank2 roject, as well as the software that was in the ./software folder of the projekt.

I had to comment three lines out which would print the rank and two other things, cause these werent found somehow.

Which software did you use? the one in the projekt or the original one?

when i use the memorytest from template (new projekt and bsp->memory test) the system seems to reset too.

this looks like some error in the quartus model then? everytime i try to access memory i get a reset.

EDIT:

i tested somethoing differnt now.

my memory is from 0x00000000 to 0x3fffffff

when i test it from eg 0x00000000 to 0x00010000 or from 0x10000000 to 0x20000000 it works fine.

that means the mempory doesnt work correctly? but why does the testprogram crash and i'm not getting an error?
