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

  1. Build the Zephyr kernel and the Hello World sample application:

    # From the root of the zephyr repository
west build -b ai_m62_12f_kit samples/hello_world
west flash

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

    $ 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

    *** 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.
