I attempted to implement a watchdog timer on my nRF52840 board (version 1.2.0), but the target board does not appear to have the watchdog properly configured.

The Ebyte/nRF chip itself includes a watchdog, and when I use the default development board configuration, the watchdog works as expected. However, it fails on my custom target board.

I currently don’t have enough experience to identify or resolve the issue on my own. Any guidance on how to properly enable or configure the watchdog for this board would be greatly appreciated.
