HRESET not being released

We have 2 prototype boards using the T2081. One board will not release HRESET. We are using a hard coded RCW just so we can connect the emulator and begin development. The other board has a power supply problem so we do not have one that is working at the moment. I have verified the Hard coded RCW is correct at the time when PORESET is released. What could cause the T2081 from not completing the hard coded RCW process? Voltages are good, clocks seem clean.#

Signal IFC_AVD was being pulled low during PORESET. I have it pulled up on the board so I'm not sure why it's low at this point. I cut the trace going to the level shifter and now the T2081 releases HRESET,
