8 Minor release updates[edit]

STMicroelectronics regularly delivers corrections through github® components which are u-boot, optee-os, tf-a, Linux kernel.
You can decide to incorporate them into your developer package (please refer to STM32MP1 Developer Package) or Distribution package.
For updating Distribution package please proceed as follow:

  1. Switch to github® mode your Distribution package
  2. Use the command devtool modify <recipe name> to have direct access to source code git used by build process
  3. In source code just extracted, use git command as git checkout -b WORK <github® TAG> to points on new revision of component

More rarely and independently, STMicroelectronics also delivers fixes on layers through github®. These changes can be integrated (via git commands) into your local STM32MP1 Distribution Package environment. Please find below the github® links of the quoted layers :

12.1 Detailed description of STMicroelectronics layers[edit]

In OpenEmbedded, the build framework which was chosen by the OpenSTLinux distribution, a layer is a collection of recipes and/or configurations that can be used on top of OE-Core.

Typically, each layer is organized around a specific theme, such as adding recipes for building web browser software.

The implemented layers are listed below, together with the list of recipes contained in each layer and the related information.
