Do you have any insight into what the problem was with the core you were using.

I believe I am suffering a similar problem albeit in a different environment. I am using a cyclone dev kit with quartus 4.2 sp 1 and nios ii 1.1 (latest). Using the HAL but no OS.

I have binned the sdram and located my application in sram. I can download code to the board and make it run but when I try to debug I see very similar messages.

The console is unresponsive and the message 'processor already paused' is worryingly there.

I have also seen a message which says error accessing memory address 0x80035c (0x800000 being the base of sram).

if there is something about the sdram controller which caused gdb to stall maybe it is also causing me a problem at the moment. perhaps you could enlighten me ?
