u-blox BMD-345-EVAL

Hardware

Platform Nordic nRF52: The nRF52 Series are built for speed to carry out increasingly complex tasks in the shortest possible time and return to sleep, conserving precious battery power. They have a Cortex-M4F processor which makes them quite capable Bluetooth Smart SoCs.

Microcontroller	NRF52840
Frequency	64MHz
Flash	1MB
RAM	256KB
Vendor	u-blox

Configuration

Please use ublox_bmd345eval_nrf52840 ID for board option in “platformio.ini” (Project Configuration File):

[env:ublox_bmd345eval_nrf52840]
platform = nordicnrf52
board = ublox_bmd345eval_nrf52840

You can override default u-blox BMD-345-EVAL settings per build environment using board_*** option, where *** is a JSON object path from board manifest ublox_bmd345eval_nrf52840.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:ublox_bmd345eval_nrf52840]
platform = nordicnrf52
board = ublox_bmd345eval_nrf52840

; change microcontroller
board_build.mcu = nrf52840

; change MCU frequency
board_build.f_cpu = 64000000L

Uploading

u-blox BMD-345-EVAL 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:ublox_bmd345eval_nrf52840]
platform = nordicnrf52
board = ublox_bmd345eval_nrf52840

upload_protocol = jlink

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).

u-blox BMD-345-EVAL has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Compatible Tools	On-board	Default
Black Magic Probe
CMSIS-DAP	Yes
J-LINK	Yes	Yes
