STMicroelectronics STM32MP157F-DK2

Overview

STM32MP157F-DK2 from STMicroelectronics is a dual-core Arm Cortex-A7 (800 MHz) + Cortex-M4 evaluation kit with integrated 4" MIPI DSI LCD, Wi-Fi 802.11b/g/n, Bluetooth Low Energy 4.1, 1-Gbit/s Ethernet (RGMII), USB OTG HS, HDMI, and stereo audio codec - designed for rapid Linux-based application prototyping on STM32MP157FAC1 MPU.

For engineers reviewing the STM32MP157F-DK2 datasheet, STM32MP157F-DK2 pinout, STM32MP157F-DK2 application, or STM32MP157F-DK2 equivalent, this board supports OpenSTLinux distribution, STM32CubeMP1 firmware, and IDEs including IAR Embedded Workbench®, MDK-ARM, and STM32CubeIDE - with full GPIO expansion for Arduino® Uno V3 and Raspberry Pi® shield compatibility.

Technical Context

The STM32MP157F-DK2 implements a heterogeneous dual-processor architecture: two Cortex-A7 cores run Linux at 800 MHz while the Cortex-M4 executes real-time tasks via STM32CubeMP1; memory subsystem includes 4-Gbit DDR3L (16-bit, 533 MHz) and microSD™ storage. The STPMIC1 power management IC delivers regulated voltage rails for all domains.

Connectivity integrates RGMII-compliant 1-Gbit/s Ethernet, USB Type-C® DRP with ST-LINK/V2-1 debugger (virtual COM port + SWD), MIPI DSI® to 480×800 capacitive touch display, HDMI® transceiver, and dual-band Wi-Fi/Bluetooth LE via onboard module - all managed under mainline Linux kernel support.

FAQ

What operating systems are supported on the STM32MP157F-DK2?

The board ships with STM32 MPU OpenSTLinux Distribution (e.g., STM32MP1Starter) based on mainline Linux kernel and Yocto Project. It also supports bare-metal and RTOS execution on the Cortex-M4 core using STM32CubeMP1 firmware. Windows and macOS host environments are supported for development toolchains.

Does the STM32MP157F-DK2 include on-board debugging capability?

Yes - it integrates ST-LINK/V2-1 debugger/programmer with USB re-enumeration, providing both virtual COM port and SWD/JTAG debug interfaces over a single USB Type-C® connection. No external debugger is required for firmware flashing or real-time debugging.

How does the STM32MP157F-DK2 differ from the STM32MP157D-DK1?

The STM32MP157F-DK2 adds Secure Boot, hardware cryptography acceleration, 4" MIPI DSI LCD with capacitive touch, Wi-Fi 802.11b/g/n, and Bluetooth LE 4.1 - whereas the DK1 lacks display, wireless, and advanced security features but shares the same base MPU, DDR3L, Ethernet, and USB connectivity.

Can the STM32MP157F-DK2 be used for production deployment?

No - it is a development and evaluation platform, not qualified for mass production. For production, designers must migrate to the underlying STM32MP157FAC1 MPU in TFBGA361 package with STPMIC1, following ST's hardware design guidelines and security certification paths (e.g., PSA Certified Level 2).
