Yes, if I starting from a simple nios2 system with onchip memory, I can debug and trace my application. there is an arrow point to the 1st line of my source C code when I start debugging. But if run the same application in my nios2 system with offchip memory, then I can not debug and trace my application, all "Step Into, Step Over..." menus are grayed and not active, there is no any arrow point to my C source code.

So, I think there sould be some wrong in my system with offchip memory. But I still do not even have a clue of where the wrong is.

Could you give any further advices. Thank you.
