7 Minor release updates[edit]

STMicroelectronics regularly delivers corrections through the following github® components: u-boot, optee-os, tf-a, Linux kernel.
You can decide to incorporate them into your developer package (refer to STM32MP1 Developer Package) or Distribution package).
To update the Distribution package, proceed as follows:

  1. Switch to github® mode your Distribution package.
  2. Use the devtool modify <recipe name> command to directly access the source code git uses by build processes.
  3. In the source code just extracted, use the git checkout -b WORK <github® TAG> command such to point to the new component revision.

STMicroelectronics also delivers dedicated fixes on layers through github®. These changes can be integrated (via git commands) into your local STM32MP1 Distribution Package environment. Below the github® links corresponding to each layer:
