.. zephyr:board:: ai_m62_12f_kit

Overview

Ai-M62-12F is a Wi-Fi 6 + BLE5.3 module developed by Shenzhen Ai-Thinker Technology Co., Ltd. The module is equipped with BL616 chip as the core processor, supports Wi-Fi 802.11b/g/n/ax protocol and BLE protocol, and supports Thread protocol. The BL616 system includes a low-power 32-bit RISC-V CPU with floating-point unit, DSP unit, cache and memory, with a maximum dominant frequency of 320M.

Supported Features

.. zephyr:board-supported-hw::

System Clock

The M62 (BL616) Development Board is configured to run at maximum speed (320MHz) and can be overclocked to 480 MHz.

Serial Port

The ai_m62_12f_kit board uses UART0 as default serial port. It is connected to USB Serial converter and port is used for both program and console.

Programming and Debugging

Samples

#. Build the Zephyr kernel and the :zephyr:code-sample:hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: ai_m62_12f_kit :goals: build flash

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/dev/ttyUSB0. For example:

.. code-block:: console

  $ screen /dev/ttyUSB0 115200

Connection should be configured as follows:

  - Speed: 115200
  - Data: 8 bits
  - Parity: None
  - Stop bits: 1

Then, press and release RST button

.. code-block:: console

  *** Booting Zephyr OS build v4.2.0 ***
  Hello World! ai_m62_12f_kit/bl616c50q2i

Congratulations, you have ai_m62_12f_kit configured and running Zephyr.
