Overview
The STM32H735G-DK Discovery kit is a complete demonstration and development platform for Arm® Cortex®-M7 core-based STM32H735IGK6U microcontroller, with 1 Mbyte of Flash memory and 564 Kbytes of SRAM.
The STM32H735G-DK Discovery kit is used as a reference design for user application development before porting to the final product, thus simplifying the application development.
The full range of hardware features available on the board helps users to enhance their application development by an evaluation of all the peripherals (such as USB OTG FS, Ethernet, microSD™ card, USART, CAN FD, SAI audio DAC stereo with audio jack input and output, MEMS digital microphone, HyperRAM™, Octo-SPI Flash memory, RGB interface LCD with capacitive touch panel, and others). ARDUINO® Uno V3, Pmod™ and STMod+ connectors provide easy connection to extension shields or daughterboards for specific applications.
STLINK-V3E is integrated into the board, as the embedded in-circuit debugger and programmer for the STM32 MCU and USB Virtual COM port bridge. STM32H735G-DK board comes with the STM32CubeH7 MCU Package, which provides an STM32 comprehensive software HAL library as well as various software examples.
More information about the board can be found at the STM32H735G-DISCO website_.

For more details please refer to STM32H735G-DISCO website_.
The STM32H735G 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 550MHz. PLL clock is feed by a 25MHz high speed external clock.
The STM32H735G Discovery kit has up to 6 UARTs. The Zephyr console output is assigned to UART3 which connected to the onboard ST-LINK/V3.0. Virtual COM port interface. Default communication settings are 115200 8N1.
Programming and Debugging
.. zephyr:board-supported-runners::
STM32H735G-DISCO board includes an ST-LINK/V3 embedded debug tool interface.
See :ref:build_an_application for more information about application builds.
The board is configured to be flashed using west STM32CubeProgrammer_ runner,
so its :ref:installation <stm32cubeprog-flash-host-tools> is required.
Alternatively, OpenOCD or JLink can also be used to flash the board using
the --runner (or -r) option:
.. code-block:: console
$ west flash --runner openocd $ west flash --runner jlink
It is advised to use STM32CubeProgrammer_ to check and update option bytes
configuration.
You can debug an application in the usual way. Here is an example for the
:zephyr:code-sample:hello_world application.
