4.6 Miscellaneous[edit]

5 Main restriction list[edit]

5.1 Embedded software[edit]

5.1.1 OpenSTLinux (Cortex®-A7)[edit]

  • On STM32MP157C-DK2 boards, BT stack doesn't work any more after suspend / resume in Standby mode (function with Stop mode). The issue linked to the Murata Wifi/BT module that expects the 3V3 supply to be kept : in STM32MP1 Standby mode, this supply is switched off and so the Murata firmware is lost. A workaround can be put in place like for wifi GitHub patch with unbind/bind driver BT respectively before after resume (modprobe -r hci_uart && modprobe hci_uart)
  • For DDR initialization in TF-A, it is recommended to setup and to enable all "boot-on" and "always-on" regulators at bootloader stage, after DDR power initialization. Not yet implemented on V1.2.0 delivery and an patch is under preparation and will be pushed on Github

5.1.2 STM32CubeMP1 (Cortex®-M4)[edit]

  • To avoid errors in OpenAMP when compiling in MDK-ARM IDE, you have to disable the « Use MicroLIB » in « Target » tab
  • The HAL RTC is delivered in this release but it should be used with caution because the RTC is used by Linux, by default. To remove any risk of contention between Linux and the HAL:
    • The write protect (wpr) should be disabled by default and its should never be enabled in any driver (Linux nor HAL)
    • The HAL should only use Alarm B, since Linux is only using Alarm A
    • The RTC interrupt should be shared between Linux and the HAL, to be able to receive alarm notification on each side

5.2 STM32CubeProgrammer, Signing tool, Keygen[edit]

  • Flashload through UART fails
  • Key generation not functional with STM32MP_KeyGen_CLI on Linux with Ubuntu 16.04 (functional with Ubuntu 18.04)

5.3 STM32CubeMX[edit]

  • MR0 register for LPDDR settings not set by CubeMX in the generated device tree - Need to set manually this register at 0
  • Warning : when you open a previous project (built with CubeMX versions older than V5.6), the migration will not take into account the user sections part. This part needs to be updated manually according the Openstlinux-20-10-19 manifest

5.4 STM32CubeIDE[edit]

  • 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 menu: Help > ST-LINK Upgrade"

5.5 Miscelleanous[edit]

Restrictions lists are available in each sub-component release note, accessible from the following chapters in this same article:

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

6 Minor release updates[edit]

STMicroelectronics regularly delivers updates through github® components which are tf-a, u-boot, optee-os, Linux kernel.
You can decide to incorporate them into your Developer Package (please refer to STM32MP1 Developer Package) or Distribution Package (see below).

To update the Distribution package please proceed as follow:

  1. Switch your Distribution package reference source code to github mode
  2. Use the command devtool modify <recipe name> to have direct access to the source code git repository used by the build process
  3. In the freshly cloned source code, checkout the revision you want to start from via git checkout -b WORK <github® TAG>

More rarely and independently, STMicroelectronics also delivers fixes on layers through github®. These changes can be integrated (via git commands) into your local STM32MP1 Distribution Package environment. Please find below the github® links of the quoted layers :

7 Reference documents[edit]

All the resources for the STM32MP1 Series are located in the Resources area of the STM32MP1 Series web page.

The resources below are referenced in some of the articles of this user guide.

Info.png The different STM32MP15 microprocessor part numbers available (with their corresponding internal peripherals, security options and packages) are described in the STM32MP15 microprocessor part numbers.

New.png means that the document (or its version) is new compared to what was delivered within the previous ecosystem release.
