System Clock
Nucleo L4R5ZI System Clock could be driven by internal or external 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
The NUCLEO-L4R5ZI board includes a ST-LINK/V2 embedded debug tool interface.
Flashing
The board is configured to be flashed using west STM32CubeProgrammer runner, so its installation is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
$ west flash --runner openocd
$ west flash --runner jlink
Flashing an application to Nucleo L4R4ZI
Connect the Nucleo L4R5ZI to your host computer using the USB port. Then build and flash an application.
Here is an example for the Hello World application.
Run a serial host program to connect with your Nucleo board:
$ minicom -D /dev/ttyACM0
Then build and flash the application.
# From the root of the zephyr repository
west build -b nucleo_l4r5zi samples/hello_world
west flash
You should see the following message on the console:
Hello World! arm
