.. zephyr:board:: thingy53

Overview

Zephyr uses the thingy53/nrf5340 board configuration for building for the Thingy:53 board. The board has the nRF5340 MCU processor, a set of environmental sensors, a pushbutton, and RGB LED.

The nRF5340 is a dual-core SoC based on the Arm® Cortex®-M33 architecture, with:

a full-featured Arm Cortex-M33F core with DSP instructions, FPU, and Armv8-M Security Extension, running at up to 128 MHz, referred to as the application core
a secondary Arm Cortex-M33 core, with a reduced feature set, running at a fixed 64 MHz, referred to as the network core.

The thingy53/nrf5340/cpuapp build target provides support for the application core on the nRF5340 SoC. The thingy53/nrf5340/cpunet build target provides support for the network core on the nRF5340 SoC.

The Nordic Thingy:53 Hardware guide_ contains the processor's information and the datasheet.

Supported Features

Programming and Debugging

.. zephyr:board-supported-runners::

Flashing

Flashing Zephyr onto Thingy:53 requires an external J-Link programmer. The programmer is attached to the P9 programming header.

Debugging

Thingy:53 does not have an on-board J-Link debug IC as some other nRF5 development boards, however, instructions from the :ref:nordic_segger page also apply to this board, with the additional step of connecting an external debugger. A development board with a Debug out connector such as the :zephyr:board:nrf5340dk can be used as a debugger with Thingy:53.
