@ -5,6 +5,10 @@ Simply compile, flash, and run this tool on your nRF52x-based board. It will
program the given `RESET_PIN` into the NRF_UICR->PSELRESET registers, hence
allowing for hardware resets using a button connected to that pin.
> [!WARNING]
> This tool only works with early nRF52 chips with build codes before Fxx.
> Later build codes automatically erase the UICR register on each flashing
> operation.
