Getting Started with STM32F746G-DISCO

This page will guide you step-by-step to create your first Zephyr application on the STM32F746G-DISCO board.

The STM32F746G-DISCO Discovery kit is a powerful development board featuring an STM32F746NGH6 microcontroller with an ARM Cortex-M7 core. It includes a wide array of peripherals such as a TFT LCD, audio codec, camera interface, and onboard ST-LINK/V2-1 debugger/programmer.

  • Vendor: STMicroelectronics
  • Architecture: ARM
  • SoC: STM32F746xx

STM32F746G-DISCO

Installation​

Follow the general Installation Guide to set up your environment.

Import an SDK​

Import an minimal Zephyr SDK suitable for ARM targets:

  • Click on "Import Toolchain" or "New Toolchain"
  • Fill out the fields:
    • Source location: Official SDK
    • SDK Type: Minimal
    • Version: v0.17.0 (or newer)
    • Toolchains: arm
    • Location: e.g., path/to/sdk/arm-zephyr-sdk-0.17.0
  • Click "Import"

Import SDK

warning

The minimal SDK is fine for most base projects, but for graphical demos or advanced peripherals, a full SDK may be required.

Import ST Minimal West Workspace​

  • Click "Initialize workspace" or "New West Workspace"
  • Use the following settings:
  • Click "Import"

Import SDK

info

Workspace initialization includes fetching modules and dependencies. This may take a few minutes.

Create a New Blinky Project​

  • Click "Create New Application"
  • Select your West Workspace and Toolchain
  • Set the Board to stm32f746g_disco
  • Choose the blinky sample
  • Configure the project name and location
  • Enable Pristine Build (What is this?)
  • Click "Create"

Create blinky

Right-click your new project and click "Build".

Build

warning

Ensure your board is correctly set as stm32f746g_disco or the build may fail.

Flash and Debug Project​

Requirements​

The STM32F746G-DISCO includes an ST-LINK/V2-1 programmer/debugger that supports:

  • OpenOCD (Recommended)
  • pyOCD
  • J-Link (if used externally)
note

Zephyr Workbench includes pyOCD, but OpenOCD is often preferred for STM32 targets.

info

Make sure to install the ST-LINK USB drivers to enable communication with the debugger.

Flash and Debug​

  • Connect via USB ST-LINK port (CN5)
  • Open Debug Manager
  • Select the blinky project
  • Set the Runner to openocd (or pyocd)
  • If the runner is not detected automatically, enter its full path
  • Click "Apply"
  • Click "Debug"

Debug configuration

tip

Close other ST-LINK tools (like STM32CubeProgrammer) before flashing, as they can block the interface.
