| oscillator, as well as main PLL clock. By default, the System clock is |
| driven by the PLL clock at 80MHz, driven by a 16MHz high speed |
| internal oscillator. The clock can be boosted to 120MHz if boost mode |
| is selected. |
| |
| Serial Port |
| ----------- |
| |
| Nucleo L4R5ZI board has 5 U(S)ARTs. The Zephyr console output is |
| assigned to UART2. Default settings are 115200 8N1. |
| |
| Network interface |
| ----------------- |
| |
| Ethernet over USB is configured as the default network interface (EEM) |
| |
| Programming and Debugging |
| ************************* |
| |
| Connect the Nucleo L4R5ZI to your host computer using the USB port. |
| Then build and flash an application. Here is an example for the |
| :ref:`hello_world` application. |
| |
| Run a serial host program to connect with your Nucleo board: |
| |
| .. code-block:: console |
| |
| $ minicom -D /dev/ttyACM0 |
| |
| Then build and flash the application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: nucleo_l4r5zi |
| :goals: build flash |
| |
| You should see the following message on the console: |
| |
| .. code-block:: console |
| |
| Hello World! arm |
