Please use nrf52840_dk ID for board option in “platformio.ini” (Project Configuration File):
[env:nrf52840_dk]
platform = nordicnrf52
board = nrf52840_dk
You can override default Nordic nRF52840-DK settings per build environment using
board_*** option, where *** is a JSON object path from
board manifest nrf52840_dk.json. For example,
board_build.mcu, board_build.f_cpu, etc.
[env:nrf52840_dk]
platform = nordicnrf52
board = nrf52840_dk
; change microcontroller
board_build.mcu = nrf52840
; change MCU frequency
board_build.f_cpu = 64000000L
Nordic nRF52840-DK supports the following uploading protocols:
blackmagic
cmsis-dap
jlink
mbed
nrfjprog
stlink
Default protocol is jlink
You can change upload protocol using upload_protocol option:
[env:nrf52840_dk]
platform = nordicnrf52
board = nrf52840_dk
upload_protocol = jlink
Debugging - “1-click” solution for debugging with a zero configuration.
Warning
You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.
You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).
Nordic nRF52840-DK has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
