Configuration

Please use nrf51822_y5_mbug ID for board option in “platformio.ini” (Project Configuration File):

[env:nrf51822_y5_mbug]
platform = nordicnrf51
board = nrf51822_y5_mbug

You can override default y5 nRF51822 mbug settings per build environment using board_*** option, where *** is a JSON object path from board manifest nrf51822_y5_mbug.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:nrf51822_y5_mbug]
platform = nordicnrf51
board = nrf51822_y5_mbug

; change microcontroller
board_build.mcu = nrf51822

; change MCU frequency
board_build.f_cpu = 16000000L

Uploading

y5 nRF51822 mbug supports the following uploading protocols:

  • blackmagic

  • cmsis-dap

  • jlink

  • mbed

  • nrfjprog

  • stlink

Default protocol is cmsis-dap

You can change upload protocol using upload_protocol option:

[env:nrf51822_y5_mbug]
platform = nordicnrf51
board = nrf51822_y5_mbug

upload_protocol = cmsis-dap

Debugging

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).

y5 nRF51822 mbug has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
