Getting Started with STM32L562E-DK

This page will guide you step-by-step to create your first Zephyr application on the STM32L562E-DK board.

The STM32L562E-DK is a Discovery Kit designed for evaluating the features of the STM32L562QEI6QU ultra-low-power microcontroller. It provides multiple connectivity options, an embedded debugger (ST-LINK), and Arduino and STMod+ extension connectors for expansion.

  • Vendor: STMicroelectronics
  • Architecture: ARM
  • SoC: STM32L562xx

STM32L562E-DK

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: directory path (e.g., path/to/sdk/arm-zephyr-sdk-0.17.0)
  • Click "Import"

Import SDK

warning

A "Minimal" SDK is sufficient for basic examples, but a full SDK may be needed for advanced features like networking or USB.

Import ST Minimal West Workspace​

Import a minimal west workspace for STM32:

  • Click "Initialize workspace" or "New West Workspace"
  • Fill in the fields:
  • Click "Import"

Init workspace

info

Workspace initialization may take a few minutes, especially on first launch when dependencies are resolved.

Create a New Blinky Project​

With everything ready, let's create a blinky app:

  • Click "Create New Application"
  • Choose your initialized West Workspace
  • Select your imported Zephyr SDK
  • Set the Board to stm32l562e_dk
  • Choose blinky as the sample
  • Set your project name and location
  • Enable Pristine Build (learn more)
  • Click "Create"

Create blinky

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

Build

tip

If the build fails, double-check that your SDK matches the board's architecture and the board name is exactly stm32l562e_dk.

Flash and Debug Project​

Requirements​

The STM32L562E-DK includes an ST-LINK/V3E probe supporting:

  • OpenOCD (Recommended)
  • pyOCD
  • J-Link (external, optional)
info

Zephyr Workbench includes pyOCD by default. OpenOCD is supported but may require separate installation.

warning

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

Flash and Debug​

  • Connect your PC to the board using the USB ST-LINK port (CN7)
  • Open Debug Manager
  • Select your blinky application
  • Choose pyocd (or openocd) as the runner
    (You should see "Runner executable found" if correctly installed)
  • If not found, manually set the path to the runner binary

Debug configuration

  • Click "Apply"
  • Click "Debug"
tip

Make sure no other software (like STM32CubeProgrammer) is using the ST-LINK interface.
