Hi, I have a board SAMA5D31EK that is programmed with bootloaders etc to boot linux. The board is fitted with 12MHz crystal and boots fine.
Due to some EMI issues, I want to replace the crystal with a spread spectrum oscillator. I have done the modification to the hardware and can measure the spread clock on the XIN pin of SAM, but SAMA5D31 remains in "Romboot" and the SAM-BA port is not active.
Is there something else I am missing with this?
Is it in fact possible to use a SS Osc? It is mentioned in the AN as given below:

What must be done with the XOUT pin?
Hope someone can help urgently, I have test lab booked for Thursday and it would be a waste not to test this.
