Yocto Project Summit 2025.12

Yocto BSP with STM32MP
2025-12-02 , Walnascar

This talk explains how STM32MP BSP Layer is developed and organized.


The community finds the STMP32MP Yocto BSP Layer is quite complicated, and it is quite difficult to developed a new machine based on ST machine configuration.

The aim of this talk is to give a BSP implementation example, as well as how ST abstracts key BitBake BSP variables and uses advanced development techniques to support their boards in a generic way.

Talking about STM32MP, STM32MP2 specifically, also means talking about ARM Trust Boot and firmware update and how ST handles that in Yocto.
