| 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 nrf5340dk_nrf5340_cpuapp build target provides support for the application |
| core on the nRF5340 SoC. The nrf5340dk_nrf5340_cpunet build target provides |
| support for the network core on the nRF5340 SoC. |
| |
| |
| The `Nordic Semiconductor Infocenter`_ contains the processor's information and |
| the datasheet. |

| Programming and Debugging |
| ************************* |
| |
| 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 |
| :ref:`nrf5340dk_nrf5340` can be used as a debugger with Thingy:53. |
