On many (all?) nrf52840dk boards, the reset pin is not configured out-of-the box. This means, that simply nothing happens if the RESET pin is pressed. To change this, RIOT provides a little tool in dist/tools/nrf52_resetpin_cfg.
Simply compile, flash, and run that tool on your board, and the reset pin should work for the time being.
See the Flashing section in nRF52 common.
The STDIO is directly accessible via the USB port. On a Linux host, it's generally mapped to /dev/ttyACM0.
