Hi,
sdk: ncs v1.5.0
path:D:\ncs\v1.5.0\applications\2_hello_world_board
overlay file path:D:\ncs\v1.5.0\applications\2_hello_world_board\board.overlay
if i change the overlay file name as nrf5340dk_nrf5340_cpuapp.overlay,Settings are available.
if i change the overlay file name as board.overlay,Settings are not available.
How to set it up to change the name of the overlay file to:board.overlay.

Thank you for all your assistance.
Kind regards,
Peter.Min
