8. Minor release updates[edit source]

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:

Switch to github^® mode your Distribution package
Use the command devtool modify <recipe name> to have direct access to source code git used by build process
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 :

8.1. v1.1.1[edit source]
