Are you sure there isn't a second capacitor between the zero-ohm resistor and ground? Otherwise it doesn't make sense to populate a capacitor if it is to be bypassed by a shorting link. :-?
The same thought I have too.. why to short a capacitor with a resistor? Any thoughts are welcomed.
Finally, I replaced the chip LTC3850 and the PCB works ok.
P.S. Thank you very much for yoru reply.
