Clock speed is 48 MHz. Nothing on hardware has changed between when it worked and now. I confirmed today that console i/o works fine with an earlier version of my IP and software design. The problem has something to do with either my curent IP design, current software design, or BSP settings, although I tried mirroring BSP settings from the working version into the broken version and nothing changed, so I am inclined to think the BSP settings are unlikely to be the problem at this point.

Since I have a working version, worst case I can morph the working one towards the current one until it breaks to find the answer. I would still prefer to avoid that path if possible.
