There are 1 incomplete or pending task to finish installation of Semantic MediaWiki. An administrator or user with sufficient rights can complete it. This should be done before adding new data to avoid inconsistencies.

This page aims to provide link to the flagship/latest wiki. Each STM32 MPU ecosystem release flow has its corresponding wiki.

An ecosystem release flow designates all the ecosystem releases which are based on the same versions of the major software components (e.g. Linux^® kernel) of the OpenSTLinux distribution (see details in the below table).
Each vx flow groups together all the vx.y.z ecosystem releases, and has its own wiki.

The most recent flow is associated with the flagship/latest wiki (whose URL is "https://wiki.st.com/stm32mpu"), while the previous flows are associated with archived wikis (whose URLs are "https://wiki.st.com/stm32mpu-ecosystem-vx").

This current wiki is a wiki archived for the v3 flow (v3.y.z ecosystem releases): if you need information about this ecosystem releases flow, continue browsing this wiki.

However, if you discover the STM32 Arm^® Cortex^®-based MPUs, it is highly recommended to browse the flagship/latest wiki that contains the latest major ecosystem release:
