As a little clarification, it does not disconnect when I hit a breakpoint or I stop the program, it is when I try to look at a variable or a register. I havle looked around and cannot find much about how to configure the chip for debugging, other than if it is set to be secure debugging does not work. Is there a setting in the eclipse environment that sets the secure bit? As I remember, the secure bit is set when you are building the image to store on the Cyclone.
I have the clock setup in PEE mode to do USB, and in fact, the clock setup and chip setup were taken from a project I developed on a winxp box with very little trouble in debugging.
Any hints on where to look?
