Connections and IOs
The Nucleo F303RE Board has 5 GPIO controllers. These controllers are responsible for pin muxing, input/output, pull-up, etc.
Board connectors:
Default Zephyr Peripheral Mapping:
The Nucleo F303RE board features an Arduino Uno V3 connector and a ST morpho connector. Board is configured as follows:
UART_2 TX/RX : PA2/PA3 (ST-Link Virtual Port Com)
USER_PB : PC13
LD2 : PA5
System Clock
The Nucleo F303RE System Clock can be driven by an internal or external oscillator, as well as by the main PLL clock. By default the System Clock is driven by the PLL clock at 72 MHz. The input to the PLL is an 8 MHz external clock supplied by the processor of the on-board ST-LINK/V2-1 debugger/programmer.
Serial Port
The Nucleo F303RE board has 2 UARTs. The Zephyr console output is assigned to UART2. Default settings are 115200 8N1.
Programming and Debugging
The Nucleo F303RE board includes an ST-LINK/V2-1 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
