System Clock
The STM32H7B3I 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 280MHz. PLL clock is fed by a 24MHz high speed external clock.
Serial Port
The STM32H7B3I Discovery kit has up to 10 UARTs. The Zephyr console output is assigned to UART1 which is connected to the onboard STLINK-V3E. Virtual COM port interface default communication settings are 115200 8N1.
Programming and Debugging
STM32H7B3I Discovery kit includes an STLINK-V3E embedded debug tool interface.
Applications for the stm32h7b3i_dk board configuration can be built and
flashed in the usual way (see Building an Application and
Run an Application for more details).
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 may depend on the SoC option bytes configuration, which can be checked and updated using STM32CubeProgrammer.
Flashing an application to STM32H7B3I
First, connect the STM32H7B3I Discovery kit to your host computer using the USB port to prepare it for flashing. Then build and flash your application.
Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b stm32h7b3i_dk samples/hello_world
west flash
Run a serial host program to connect with your board:
$ minicom -D /dev/ttyACM0
You should see the following message on the console:
Hello World! arm
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b stm32h7b3i_dk samples/hello_world
west debug
