- SCMI - SCMI support for clocks and resets
- The system control and management interface (SCMI) is an OS independent interface proposed by ARM implemented in the secure monitor (TF-A sp_min or OP-TEE) and called by the application (U-Boot, Linux) for clock and reset management. It allows a centralized control of those system resources, with filtering possibilities.
- Supports DVFS 800 MHz - 400 MHz
- Operating points DT management wiki article - refer to How_to_change_the_CPU_frequency article
- SNAND - Full SPI Nand support including boot and Flash
- SoC and Boards device tree new split
- 1 device tree per board CPN, dtsi device trees are split between SoC Product lines, SoC extensions (security and Cortex A frequency) and SoC package types - refer to the STM32MP15_device_tree article
- OpenSTLinux debug with gdb management
- Basic boot removed except for DDR tuning tool
- ST reference boot is the Trusted with TF-A=>U-BOOT=>Kernel
- UART RS485 support
- Yocto build process
- SSP feature (Secure Secrets Provisonning) delivered with a specific TF-A branch managed with a dedicated Yocto recipe tf-a-stm32mp-ssp_2.2.bb
- A dedicated Yocto recipe is also added to manage the TF-A for serial boot tf-a-stm32mp-serialboot_2.2.bb additionally to tf-a-stm32mp_2.2.bb. The 2 recipes are included in ST yocto images. It allows to use a dedicated TF-A binary for serial boot with STM32CubeProgrammer tool and to save size for the TF-A binary used for the product.
- Internal peripheral assignment at boot time
- At boot time, you can select two 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 you do not specify "2" in the U-Boot console.
- More information can be found in the How to assign an internal peripheral to a runtime context article.

5 Main restrictions
5.1 Embedded software
5.1.1 OpenSTLinux (Cortex®-A7)
5.1.2 STM32CubeMP1 (Cortex®-M4)
- To avoid errors in OpenAMP when compiling in MDK-ARM IDE, disable the « Use MicroLIB » in « Target » tab.
- Please 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
- Key generation is not functional with STM32MP_KeyGen_CLI on Linux under Ubuntu 16.04 (functional with Ubuntu 18.04).
- Warning: when opening a previous project built with STM32CubeMX version older than V6.0, the migration does not take into account the user section part. This part needs to be updated manually according the Openstlinux-5.4-dunfell-mp1-20-06-24 manifest.
- Using OpenOCD with ST-LINK does not check and force ST-LINK firmware update at debug launch. It is therefore recommended to manually update to the latest ST-LINK firmware for the best debug experience. Use the Help > ST-LINK Upgrade menu".
Restriction lists are available in each subcomponent release note. They are available in the following chapters in the present article:
Moreover, the software workarounds implemented in the ecosystem to provide solutions to the STM32MPU device errata are listed in STM32MP15 ecosystem errata sheet.
6 Minor release updates
STMicroelectronics regularly delivers updates through the following github® components: tf-a, u-boot, optee-os, Linux kernel.
You can decide to incorporate them into your Developer Package (refer to STM32MP1 Developer Package or Distribution Package below).
To update the Distribution package, proceed as follows:
- Switch your Distribution package reference source code to github mode.
- Use the devtool modify <recipe name> command to have direct access to the source code git repository used by the build process.
- In the freshly cloned source code, check out the revision you want to start from via git checkout -b WORK <github® TAG>.
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 layers:
