Release Notes 2.6.1
1. Overview
This is the Linux BSP (Board Support Package) and the development environment for the STM32H7 System-On-Module (SOM) and Starter Kit, release 2.6.1.
The BSP provides a software development environment for evaluation and development of Linux (uClinux) on the Cortex-M7 processor core of the STM32H7 microcontroller using the Emcraft STM32H7 SOM Starter Kit as a hardware platform.
