Does the QorIQ T1040/T1042 Eval board use spread spectrum clocking or standard clocking. I know the processor supports both, but some PCIe devices cannot support this. Need to know what is supported.

The T1040/T1042 uP supports spread spectrum clocking, but it is dependent on the clock source.  Is the T1040/T1042 Eval board designed with a spread spectrum clock or a standard clock.  We have some PCIe devices hanging on the intial probe and they say they don't support spread spectrum clocking.

Spread-spectrum is disabled on the T104xRDB.
