If you're not seeing CS0 move at all, then you've got trouble. Does it move at all? Even while HRSET is asserted?
While HRESET is asserted it should toggle to retrieve the HR Reset Config Word. If this is not happening then the PLL's probably aren't locking.
I would look into your clock - make sure it's stable.
If it toggles during HRESET (to fetch the reset word) but not after reset is de-asserted, then I would make sure all of your TA signals (i.e. GTA) are pulled up. And also make sure you're loading the correct HW Config word into the processor.
