System Clock
Nucleo F207ZG System Clock could be driven by internal or external oscillator, as well as main PLL clock. By default System clock is driven by PLL clock at 120MHz, driven by 8MHz high speed external clock.
Serial Port
Nucleo F207ZG board has 4 UARTs. The Zephyr console output is assigned to UART3. Default settings are 115200 8N1.
Network interface
Ethernet configured as the default network interface
USB
Nucleo F207ZG board has a USB OTG dual-role device (DRD) controller that supports both device and host functions through its micro USB connector (USB USER). Only USB device function is supported in Zephyr at the moment.
Backup SRAM
In order to test backup SRAM you may want to disconnect VBAT from VDD. You can
do it by removing SB156
jumper on the back side of the board.
Programming and Debugging
Nucleo F207ZG 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
