STMicroelectronics STM32MP157A-EV1

Overview

STM32MP157A-EV1 from STMicroelectronics is a full-featured evaluation board for the STM32MP157AAA3 dual-core Arm Cortex-A7 + Cortex-M4 microprocessor, featuring 2×4-Gbit DDR3L RAM, 32-Gbit eMMC v5.0, CAN FD interface, 1-Gbps Ethernet (RGMII), and a 5.5" MIPI DSI TFT display with capacitive touch. It targets Linux-based embedded application development in industrial HMI and edge gateway prototyping.

For engineers reviewing the STM32MP157A-EV1 datasheet, STM32MP157A-EV1 pinout, STM32MP157A-EV1 application, or STM32MP157A-EV1 equivalent, key selection considerations include on-board ST-LINK/V2-1 debugger support, OpenSTLinux and STM32CubeMP1 software stack compatibility, PMIC integration (STPMIC1), and Raspberry Pi® shield expansion capability via GPIO header.

Technical Context

The board implements the STM32MP157AAA3 MPU in LFBGA448 package with basic security features (no Secure Boot or hardware cryptography), paired with STPMIC1 power management IC for multi-rail voltage regulation. It supports mainline Linux kernel execution on Cortex-A7 cores and real-time firmware on Cortex-M4 core.

Hardware interfaces include RGMII-compliant 1-Gbps Ethernet PHY, CAN FD transceiver, USB OTG HS with Micro-AB connector, four USB 2.0 Host ports, SPDIF I/O, stereo headset jack with analog mic input, and MIPI DSI interface driving a 720×1280 LCD panel with LED backlight.

FAQ

What distinguishes STM32MP157A-EV1 from STM32MP157C-EV1?

The STM32MP157A-EV1 uses the STM32MP157AAA3 MPU with basic security features only, while the STM32MP157C-EV1 uses the STM32MP157CAA3 variant supporting Secure Boot and hardware-accelerated cryptography. Both share identical hardware layout, peripherals, and mechanical design.

Does STM32MP157A-EV1 include an on-board debugger?

Yes - it integrates ST-LINK/V2-1 as an embedded debugger/programmer with USB re-enumeration capability, providing both Virtual COM port and SWD/JTAG debug interfaces without requiring external tools.

Which operating systems and IDEs are supported?

It supports mainline Linux via STM32 MPU OpenSTLinux Distribution (e.g., STM32MP1Starter), along with STM32CubeMP1 for Cortex-M4 firmware. Development toolchains include Keil MDK-ARM, IAR EWARM, and GCC-based IDEs on Windows, Linux, or macOS.

Can Raspberry Pi® shields be used directly with this board?

Yes - the board provides a 40-pin GPIO expansion connector mechanically and electrically compatible with Raspberry Pi® Model B+ and later, enabling direct use of standard Raspberry Pi® HATs and shields for rapid peripheral integration.
