Overview

The NUCODE NU32 is a compact module based on the Nordic Semiconductor nRF52832 ARM Cortex-M4F SoC. It supports Bluetooth Low Energy (BLE) 5.x and NFC-A. Unlike the NUCODE NU40, the nRF52832 has no USB device controller, so firmware is programmed over the SWD debug interface.

More information about the board can be found at the NUCODE NU32 website [1].

Hardware

The nucode_nu32/nrf52832 board target is built around the nRF52832 (512 KB flash, 64 KB RAM, QFN48). The board uses the nRF52832 internal low-frequency RC oscillator by default.

Connections and IOs

UART

• UART0: TX = P0.06, RX = P0.08, RTS = P0.05, CTS = P0.07

NFC

• NFC-A antenna pins: P0.09 and P0.10

Reset

• RESET = P0.21 (configured through UICR as the hardware reset pin)

SWD

• The SWDCLK and SWDIO debug pads are used for flashing and debugging.

Programming and Debugging

The nucode_nu32 board supports the runners and associated west commands listed below.

	flash	debug	debugserver	attach	rtt	reset
jlink	✅	✅ (default)	✅	✅	✅	✅
nrfjprog	✅
nrfutil	✅ (default)
openocd	✅	✅	✅	✅	✅
pyocd	✅	✅	✅	✅	✅

Applications for the nucode_nu32/nrf52832 board target can be built and flashed in the usual way (see Building an Application and Run an Application for more details).

Flashing

The board is programmed and debugged using an external debug probe (for example a SEGGER J-Link) connected to the SWD pads.

1. Build and flash the Hello World sample:

   # From the root of the zephyr repository
   west build -b nucode_nu32/nrf52832 samples/hello_world
   west flash
   

2. Open a serial terminal (115200 8N1) connected to the UART0 pins and reset the board to see the output.

Debugging

Refer to the Run an Application page for more details on debugging.
