Questions about SDRAM memory test on CyIII DK

I am using the Cyclone III Development Kit with the Triple Speed Ethernet Reference Design that has 128MB SDRAM configured. I am running the Memory Test program built from the Nios project template....

The memory that is being tested cannot be used for Reset or Exception Addresses or (to be safe) any linker sections.

To me, it sounds like the Exception Address is pointed to this memory. You'd have to open the Nios II in SOPC Builder, point the exception address elsewhere, re-generate in SOPC Builder, re-compile in QII...and then re-run the memory test.

Or, you could just live with where it does work.
