I found this circuit from Antmicro opensource hardware used in Jetson nano base board project.
Why they put R 0 Ohm in this circuit?
Thank you

Zero ohm resistors are often used to allow optional parts or change the signal paths. It allows you to 'disconnect' a part of the circuit.
A little overkill here in my opinion.

I'm guessing in this case it gives you a chance to add a small series resistance if you have issues with radiated EMI maybe?Comment

Ant1882 You would need to see the bigger picture (schematic and layout) if this could be for EMI.
For the reset I would rather pick a 1k resistor or so, as this allows you to physically reset (during development) with damaging anything.Comment
