STM32MP Development
Production-ready STMicroelectronics STM32MP257F-DK deployment in 4 months with Avocado Connect + Avocado OS
10x Faster Development | 3x Fewer Engineers | 1.35 TOPS AI Performance
Overview
The STMicroelectronics STM32MP257F-DK, powered by Avocado Linux and Avocado Connect, transforms industrial embedded development from an 18-month journey into a 4-month production deployment. This heterogeneous platform combines dual Cortex-A35 cores, a Cortex-M33 real-time processor, and a 1.35 TOPS NPU to deliver sophisticated edge AI capabilities with deterministic real-time control. The pre-integrated Yocto-based Linux distribution eliminates months of complex dual-core system integration, while enterprise OTA updates and fleet management ensure secure, scalable deployment across industrial environments. Perfect for smart manufacturing, IoT gateways, and HMI controllers, the solution enables teams to leverage STM32's industrial heritage and -40°C to +85°C operation while reducing development teams by 3x and accelerating time to market by 10x.

Getting Started
Init, Install, & Build
Follow the Any Supported Target instructions under Getting Started to begin. This target is stm32mp257f-dk. The provisioning specifics are below.
Provision
Build the project and execute the provisioning procedure. This will build the system image and flash it to your target hardware.
Some Linux operating systems, like Ubuntu, will attempt to auto-mount mass storage devices. This can interfere with Avocado's ability to finalize provisioning a device.
Before provisioning, disable auto-mounting. The following example is for Ubuntu (GNOME desktop); the same commands apply to other GNOME-based distributions such as Fedora Workstation.
gsettings set org.gnome.desktop.media-handling automount false
gsettings set org.gnome.desktop.media-handling automount-open false
avocado build
avocado provision -r dev --profile sd
Run
After provisioning completes, insert the SD card into your target device and power it on.
The device will boot from the SD card with the provisioned system. The root user is passwordless in the dev runtime used by this guide.
