Detailed Description

Common files and configuration for nRF52 boards.

Flashing nrf52 boards

By default, nrf52 boards are flashed using Jlink. nRF52840-MDK uses PyOCD by default.

To flash the board, use BOARD=<nrf52 board> with the make command.
Example with hello-world application:

make BOARD=<nrf52 board> -C examples/hello-world flash

OpenOCD can also be used to flash nrf52 boards (except thingy52 and ruuvitag because they are hardly coupled with JLink segger_rtt stdio). For the moment, the latest stable version of OpenOCD (0.10) doesn't contain any support for nrf52 but versions built against the current development version can be used.

To flash the board with OpenOCD, use the PROGRAMMER variable:

PROGRAMMER=openocd make BOARD=<nrf52 board> -C examples/hello-world flash
