6. Release change notification[edit | edit source]

OpenSTLinux attention points to switch from ecosystem release v5.0.0 More info.png to ecosystem release v5.1.0 More info.png are documented in STM32 MPU OpenSTLinux release changes notification – v5.1.0 article.

7. Recommendations for use[edit | edit source]

7.1. Safe use[edit | edit source]

  • Flash programming and boot from all supported flash devices: SD card, eMMC, ONFI NAND and NOR flash memories.
  • Develop Linux® applications, libraries, kernel modules based on OpenSTLinux delivery.
  • Develop coprocessor Cube applications based on STM32CubeMP1 and STM32CubeMP2 deliveries.
  • Develop boards based on STM32MP1 series and STM32MP25x lines More info.png.
  • Prototype applications based on ST boards.

7.2. Non-recommended use[edit | edit source]

  • None

8. Restrictions[edit | edit source]

STM32MP25x lines More info.png

  • dcmipp-isp-ctrl tool will fail whenever DCMIPP auxiliary pipe only is used for camera capture (need to enable DCMIPP main pipe).

STM32MP1 series

  • The partition layout always keeps the Firmware Update related partitions even if machine feature fw-update is disabled. To optimize the partition layout without Firmware Update feature, modifications are needed on flashlayout file generation and also on U-Boot source code in case of MTD partitions (storage mapping is hardcoded for MTD partitions, see How_to_configure_U-Boot_for_your_board#MTD_partitions)
  • STM32MP15x lines More info.png: Issue to boot with SPI-Nand: patches to be upstreamed on GitHub

9. Minor release updates[edit | edit source]

STMicroelectronics regularly delivers corrections through github® components which are U-Boot , OP-TEE , TF-A , Linux kernel .


The corrections can be incorporated into the STM32MPU 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 STM32MPU Distribution Package environment. See below the github® links of the quoted layers :
  • Get a new Distribution Package:
Refer to Installing_the_OpenSTLinux_distribution page for installing instructions, and use the repo command given for the minor version below, if it exists.

10. How to get started with openstlinux-6.1-yocto-mickledore-mpu-v24.06.26[edit | edit source]
