System requirements

Prerequisites

Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command below to retrieve those files.

west blobs fetch hal_espressif

Note

It is recommended running the command above after west update.

Building & Flashing

Build and flash applications as usual (see Building an Application and Run an Application for more details).

# From the root of the zephyr repository
west build -b kincony_kc868_a32 samples/hello_world

The usual flash target will work with the kincony_kc868_a32 board configuration. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b kincony_kc868_a32 samples/hello_world
west flash

Open the serial monitor using the following command:

west espressif monitor

After the board has automatically reset and booted, you should see the following message in the monitor:

***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx *****
Hello World! kincony_kc868_a32

Enabling Ethernet

Enable Ethernet in KConfig:

CONFIG_NETWORKING=y
CONFIG_NET_L2_ETHERNET=y
CONFIG_MDIO=y
