Warning white.png Warning
Basic boot has been removed since STM32MP15-ecosystem-v2.0.0, if using basic boot with U-BOOT-SPL to load U-BOOT and the Kernel, use now the ST reference boot scheme replacing U-BOOT-SPL by TF-A as FSBL as explained in Boot chain overview.
  • Internal peripheral assignment at boot time
    • At boot time, select one of both kernel configurations:
      • Configuration 1: all internal peripherals are assigned to Cortex-A7 for Linux drivers. Cortex-M4 coprocessing firmware TTY is executed by default.
      • Configuration 2: some internal peripherals are assigned to Cortex-M4 to execute Cortex-M4 delivered examples on the board (EVAL or DISCO) see (How to run 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.

4.6 Miscellaneous[edit]

Detailed features are available in the release notes of the different components that constitute this delivery.

See sections STM32MPU Embedded Software distribution detailed release notes, Referenced tools release notes and Reference documents

5 Main restrictions[edit]

5.1 Embedded software[edit]

5.1.1 OpenSTLinux (Cortex®-A7)[edit]


5.1.2 Buildroot (Cortex®-A7)[edit]


5.1.3 STM32CubeMP1 (Cortex®-M4)[edit]

  • Use the HAL RTC with caution since this driver is also used by Linux. To remove any risk of contention between Linux and the HAL, proceed as follows:
    • The write protect (wpr) must be disabled by default and it must never be enabled in any driver (Linux nor HAL).
    • The HAL must use only Alarm B, since Linux uses Alarm A.
    • The RTC interrupt must be shared between Linux and the HAL to be able to receive alarm notifications on both sides.

5.2 STM32CubeProgrammer, Signing tool and Keygen[edit]

Warning white.png Warning
Key generation is functional with STM32MP_KeyGen_CLI on Linux from Ubuntu 18.04 and upper versions.

5.3 STM32CubeMX[edit]

Warning white.png Warning
When opening a previous project built with an STM32CubeMX version older than V6.4.0, the migration does not take into account the user section part. This part needs to be updated manually according the openstlinux-5.10-dunfell-mp1-21-11-17 manifest.

5.4 STM32CubeIDE[edit]

  • Using OpenOCD with ST-LINK does not check nor force ST-LINK firmware update at debug launch. It is therefore recommended to manually update the latest ST-LINK firmware for the best debug experience. Use the Help > ST-LINK Upgrade menu".

5.5 Miscellaneous[edit]

Restriction lists are available in the sub-components release notes, which are available in the following chapters:

Moreover, the software workarounds implemented to provide solutions to the STM32MPU device errata are listed in STM32MP15 ecosystem errata sheet.

6 Minor release updates[edit]

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:
  1. Switch your Distribution Package to # github® mode .
  2. Use the devtool modify <recipe name> command to set up an environment. It will fetch and unpack the source code.
  3. 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
