Overview |
|
******** |
|
|
|
The YD-STM32H750VB development board is a complete demonstration and development |
|
platform for Arm |reg| Cortex |reg|-M7 core-based STM32H750VBT6 microcontroller, with |
|
128Kbytes of Flash memory and 1 Mbytes of SRAM. |
|
|
|

Supported Features |
|
================== |
|
|
|
.. zephyr:board-supported-hw:: |

|
|
Pin Mapping |
|
=========== |
|
|
|
Default Zephyr Peripheral Mapping: |
|
---------------------------------- |
|
|
|
- UART_1_TX : PA9 |
|
- UART_1_RX : PA10 |
|
- LED_1 : PA13 (SWDIO) |
|
- LED_2 : PA14 (SWCLK) |
|
- LED_3 : PA15 |
|
- LED_4 : PB4 |
|
- KEY : PB3 |
|
|
|
System Clock |
|
============ |
|
|
|
The STM32H750VB 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 480MHz. PLL clock is feed by a 25MHz high speed external clock. |
|
|
|
Flashing |
|
======== |
|
|
|
.. zephyr:board-supported-runners:: |
|
|
|
There are 2 main entry points for flashing STM32H750VB SoCs, one using the ROM |
|
bootloader, and another by using the SWD debug port (which requires additional |
|
hardware such as ST-Link). Flashing using the ROM bootloader requires a special activation |
|
pattern, which can be triggered by using the BOOT0 button. |
|
|
|
Installing dfu-util |
|
------------------- |
|
|
|
It is recommended to use at least v0.8 of `dfu-util`_. The package available in |
|
debian/ubuntu can be quite old, so you might have to build dfu-util from source. |
|
|
|
There is also a Windows version which works, but you may have to install the |
|
right USB drivers with a tool like `Zadig`_. |
|
|
|
Flashing an application to YD-STM32H750VB |
|
----------------------------------------- |
|
|
|
Connect a USB-C cable and the board should power ON. Force the board into DFU mode |
|
by keeping the BOOT0 switch pressed while pressing and releasing the RST switch. |
|
|
|
The dfu-util runner is supported on this board and so a sample can be built and |
|
tested easily. |
|
|
|
Here is an example for the :zephyr:code-sample:`blinky` application. |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/basic/blinky |
|
:board: yd_stm32h750vb |
|
:goals: build flash |
|
|
|
You will see the LED blinking every second. |
|
|
|
Debugging |
|
========= |
|
|
|
You can debug an application in the usual way. Here is an example for the |
|
:zephyr:code-sample:`hello_world` application. |
|
|
|
.. zephyr-app-commands:: |
|
:zephyr-app: samples/hello_world |
|
:board: yd_stm32h750vb |
|
:goals: debug |
|
