Hi Gokul, The layout / schematic look fine. Any chance you can try a higher frequency XTAL or some sort of external differential clock source to debug the board otherwise? How are you looking for the XTAL oscillation - Are you putting a scope probe on it? Could the scope probe capacitance be responsible for attenuating or stopping the XTAL from oscillation? Can the XTAL oscillation be "sniffed" with a high frequency probe close by without touching the leads? Regards, Hooman
