Semantic MediaWiki

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 links to archived wikis. 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 table below).
Each vx flow groups together all the vx.y.z ecosystem releases, and has its own wiki.

The most recent flow is associated with this latest wiki also known as flagship 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 flagship wiki is for the v3 flow (v3.y.z ecosystem releases): if you discover the STM32 Arm^® Cortex^®-based MPUs, it is highly recommended to continue browsing this wiki that contains the latest major ecosystem release.

However, if you need information about any previous ecosystem releases flow, browse the associated wiki thanks to the below table:

	STM32 MPU archived wiki for the v2.y.z ecosystem releases
	STM32 MPU archived wiki for the v1.y.z ecosystem releases
