Information

At boot time, STM32MP15x lines  internal peripherals are assigned according to one of the following kernel configurations: Configuration 1: all internal peripherals are assigned to the Arm® Cortex-A7 for Linux® drivers. The Arm® Cortex-M4 coprocessing TTY firmware is executed by default. Configuration 2: some internal peripherals are assigned to the Arm® Cortex-M4 to execute the delivered examples (on EVAL or DISCO board) see (How to run Arm® Cortex-M4 examples). Configuration 1 is activated by default if "2" is not specified in the U-Boot console. More information is available in the How to assign an internal peripheral to a runtime context article.

6. Minor release updates

STMicroelectronics regularly delivers corrections through github^® components which are U-Boot, OP-TEE, TF-A, Linux kernel.
The corrections can be incorporated into the Developer Package (refer to STM32MP1 Developer Package) or Distribution Package (see below).

Two possibilities exist 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 fetches and unpacks the source code.
2. In the extracted source code, use a git command such as git checkout -b WORK <github^® TAG> to point to a new revision of the 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. See below the github^® links of the quoted layers :

• meta-st-stm32mp
• meta-st-openstlinux
• meta-st-stm32mp-addons

• Get a new Distribution Package:

Refer to Installing_the_OpenSTLinux_distribution page for install instructions, and use the repo command given for the minor version below, if it exists.
