3.3 Configure LAN8651 Support on STM32F413ZH Nucleo-144 Target

  1. Make sure that the virtual environment is activated.

    source ~/zephyrproject/.venv/bin/activate

  2. Enter the directory.

    $ cd zephyrproject/zephyr/

  3. Open the nucleo_f413zh.dts file.

    $ vim boards/st/nucleo_f413zh/nucleo_f413zh.dts

  4. In the file make the adaptations as listed below (marked bold in the code section):
    • Add &dma2 node between &i2c1 node and &spi1 node.
    • In &spi1 node change sck, miso, mosi and chip select pin numbers.
    • Configure the dma channels and slots.
    • Add MAC and PHY node contents inside the &spi1 node.
