.. zephyr:board:: 32f967_dv

Elan 32f967_dv ##############

Overview

The Elan 32f967_dv is a B2B development board based on the Elan em32f967 SoC (ARM Cortex-M4). This board is used to validate the initial SoC integration with Zephyr.

Hardware

The platform provides the following hardware components:

SoC: Elan em32f967 (ARM Cortex-M4)
Maximum CPU frequency: 96 MHz
Embedded Flash: 536 KB
Embedded RAM: 272 KB
UART (debug via soldered jump wires, no dedicated connector)
SPI
GPIO
PWM
USB (used for firmware flashing and application communication)
Watchdog Timer (WDT)
Backup domain registers (accessed via Zephyr BBRAM interface)
True Random Number Generator (TRNG)
Hardware Crypto Engine
Timer
Real-Time Clock (RTC)

Supported Features

Programming and Debugging

.. zephyr:board-supported-runners::

This board does not use a standard flashing interface such as J-Link or OpenOCD.

Flashing

The flashing tool is distributed only to Elan's customers for production and evaluation purposes. It is not publicly available.

At this stage, the Zephyr west flash command is not supported.

You can build applications in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.
