Unsupported board in build Zephyr applications

I am getting an error while building Zephyr application.
The error states that "Unsupported board: led0 devicetree alias not defined".

According to this error, the swervolf_nexys board is not supported by Zephyr application but in the command line, we are giving the same board.

Any feedback will be really appreciated.

Thanks,

Start by reproducing the Zephyr application build for the swervolf_nexys board and inspect the reported missing led0 devicetree alias. Done means the board’s support status and required build configuration are established, with the error either resolved or clearly explained.
