Product details

Overview

STM32MP257F-DK from STMicroelectronics is a Discovery kit built around the STM32MP257FAK3 dual-core Arm® Cortex®-A35 (1.5 GHz) + Cortex®-M33 (400 MHz) microprocessor, featuring 32-Gbit LPDDR4, 64-Gbit eMMC v5.1, 1-Gbit/s Ethernet (RGMII), USB 3.0 SuperSpeed PD, Wi-Fi 802.11b/g/n, and Bluetooth LE v4.1 - designed for Linux-based embedded application prototyping and evaluation.

For engineers reviewing the STM32MP257F-DK datasheet, STM32MP257F-DK pinout, STM32MP257F-DK application, or STM32MP257F-DK equivalent, this board serves as a production-ready reference platform for OpenSTLinux, Yocto, Buildroot, and STM32CubeIDE development targeting industrial HMI, edge AI gateways, and secure IoT edge nodes.

Technical Context

The STM32MP257F-DK implements a full-system evaluation architecture: the main processor runs mainlined Linux via the STM32 MPU OpenSTLinux Distribution, while the coprocessor executes real-time tasks using STM32CubeMP2 firmware. It integrates STPMIC25 power management IC and supports secure boot with hardware cryptography acceleration.

Board-level interfaces include RGMII Ethernet, dual-lane MIPI CSI-2 camera expansion, HDMI and LVDS display outputs, microSD™ slot, GPIO expansion compatible with Raspberry Pi® shields, and on-board ST-LINK-V3EC debugger with virtual COM port and USB-powered operation (5 V/3 A recommended).

FAQ

What operating systems are officially supported on the STM32MP257F-DK?

The STM32MP257F-DK is validated for mainlined OpenSTLinux Distribution (based on Yocto Project®), Buildroot, and STM32CubeIDE environments. It boots Linux kernel 6.1+ with device tree support for all on-board peripherals including Ethernet, USB, HDMI, MIPI CSI-2, and Wi-Fi/Bluetooth modules. No Windows or RTOS support is provided out-of-box.

Does the board include on-chip debug capability, and what interfaces does it support?

Yes - the board integrates ST-LINK-V3EC, providing full SWD/JTAG debugging, virtual COM port (VCP), and mass storage emulation over USB Type-C®. It supports firmware programming, real-time variable inspection, and trace via CoreSight, with no external debugger required for Cortex-A35 or Cortex-M33 core development.

Can the STM32MP257F-DK boot directly from eMMC, and is secure boot enabled by default?

Yes - the board boots from its onboard 64-Gbit eMMC v5.1 by default, with optional microSD™ fallback. Secure boot is hardware-enabled via the STM32MP257FAK3's embedded cryptographic accelerators (AES-256, SHA-256, PKA), and OpenSTLinux images include signed boot chain configuration verified at each stage (ROM code → FSBL → SSBL → Linux kernel).

Is the GPIO expansion connector compatible with Raspberry Pi® HATs, and what voltage levels does it use?

Yes - the 40-pin GPIO expansion connector follows Raspberry Pi® Model B+ pinout and operates at 3.3 V logic levels. It exposes UART, I²C, SPI, PWM, and multiple GPIOs, with level-shifted signals compatible with standard Raspberry Pi® HATs and add-on boards, enabling rapid peripheral integration without custom adapter design.
