5.2 Detailed features[edit]

5.2.1 OpenSTLinux layers part[edit]

  • Rebase on Yocto 3.1.5
  • Introduce MTD partition configuration check to highlight any misalignment between STM32MP1 machine configuration and U-Boot source code
  • Add FIP support (more about FIP here) :
  • It means that only TF-A BL2 requires the stm32 header for a ROM code authentication. Others bootloader binaries are embedded in an FIP container.
  • A dedicated fip-utils-stm32mp.bbclass class is provided on meta-st-stm32mp layer side to manage the FIP image configuration, build and update.
  • A new MACHINE_FEATURES 'fip' enables the FIP binary support : this is the default and ST recommended configuration for STM32MP1 machine due to compliance with Trusted firmware-A.
Info white.png Information
Note that if no FIP binary support is expected, meaning use legacy mode with stm32 header binary files for bootloaders, remove 'fip' from MACHINE_FEATURES configuration on machine file with:
MACHINE_FEATURES_remove = "fip"

6 Recommendations for use[edit]

6.1 Safe use[edit]

  • Flash programming and boot from all supported Flash devices: SDCard, eMMC, ONFI NAND and NOR Flash memories

6.2 Non-recommended use[edit]

  • None

7 Main restrictions list[edit]

  • M-CAN Bus is not functional if power management is activated ("sleep" state defined in pinctrl): the issue is corrected thanks to this patch.

8 Minor release updates[edit]

STMicroelectronics regularly delivers corrections through github® components which are u-boot, optee-os, tf-a, Linux kernel.
The corrections can be incorporated into the Developer Package (please refer to STM32MP1 Developer Package) or Distribution Package (see below).

Two possibilities to update a Distribution Package:

  • Update your existing Distribution Package:
Switch your Distribution Package to # github® mode .
  1. Use the devtool modify <recipe name> command to set up an environment. It will fetch and unpack the source code.
  2. In the extracted source code, use a git command such as git checkout -b WORK <github® TAG> to point on new revision of component.
More rarely STMicroelectronics also delivers fixes on layers through github®. These changes can be integrated (via git commands: git checkout -b WORK <github® commit SHA1>) into the local STM32MP1 Distribution Package environment. Please find below the github® links of the quoted layers :
  • Get a new Distribution Package:
Please refer to Installing_the_OpenSTLinux_distribution page for install instructions, and use the repo command given for the minor version.

11.1 Detailed description of STMicroelectronics layers[edit]

OpenSTLinux distribution is based on the build framework OpenEmbedded.
OpenEmbedded build framework engine is named OE-Core.
A layer is a collection of recipes and/or configurations applied 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.
