Detailed Description

Support for the nRF52840 DK.

RESET pin configuration

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.

Flash the board

See the Flashing section in nRF52 common.

Accessing STDIO via UART

The STDIO is directly accessible via the USB port. On a Linux host, it's generally mapped to /dev/ttyACM0.

Use the term target to connect to the board serial port
