Koan is proud to provide the unofficial Yocto Project BSP for STM32MP1 based boards.
This project is not endorsed nor supported by ST.
ST OpenSTLinux is based on OE, our BSP extends the use of ST meta layers with Yocto, using latest commits on the branch 2.6 ‘thud’ on each meta layer.
At the moment only ST’s defined distros and images are supported out-of-the box, but you can work also with Poky ones with a little more effort.
One of the most interesting features of this approach is to have the Qt5 (release 5.11.2) support on the board and being able to generate a redistributable SDK toolchain to compile your Qt5 applications.

A direct link to the repo sources is available at GitHub

How To Prepare A Yocto Project Build Environment For STM32MP1

To get the BSP you need to have repo installed and use it as follows

Install The Repo Utility:


$ mkdir ~/bin
$ curl http://commondatastorage.googleapis.com/git-repo-downloads/repo ~/bin/repo
$ chmod a+x ~/bin/repo

Download The BSP Source:


$ PATH=${PATH}:~/bin
$ mkdir yocto-stm32mp1-koan
$ cd yocto-stm32mp1-koan
$ repo init -u https://github.com/koansoftware/koan-stm32mp-bsp-repo -b thud
$ repo sync

Setup The Build Environment:

Supported machines:

    • stm32mp1-eval
      evaluation boards (STM32MP157A-EV1 and STM32MP157C-EV1)
    • stm32mp1-disco
      discovery boards (STM32MP157A-DK1 and STM32MP157C-DK2)
    • stm32mp1
      generic board

Supported distros:

    • openstlinux-weston
      with Wayland/Weston graphic backend usage  
    • openstlinux-eglfs
      dedicated to QT usage with the eglfs graphic backend
    • openstlinux-x11
      dedicated to X11 framework usage

Supported images:

    • st-image-core
      a basic core image with ssh server, several tools for kernel, audio, network
    • st-image-weston
      image with Wayland/weston UI (if openstlinux-weston distro is used). Contains weston UI, GTK+3 demo and all tools present on st-image-core
    • st-example-image-qt
      image which demonstrates an example of Qt usage (to use with openstlinux-eglfs distro)
    • st-example-image-x11
      image which demonstrates an example of basic X11 usage (to use with openstlinux-x11 distro)
    • st-example-image-xfce
      Image which demonstrates an example of X11 usage with XFCE as UI (to use with openstlinux-x11 distro)

Note that st-example-* images have only demonstration purposes.

Example to create a new Yocto build directory with eglfs:

$ MACHINE=stm32mp1-disco DISTRO=openstlinux-eglfs source setup-environment build

Build Image:

Example to bake a Qt5 example image:


$ bitbake st-example-image-qt

At the end, enter in the scripts directory into build area and launch:

$ cd tmp-glibc/deploy/images/MACHINE_NAME/scripts
$ ./create_sdcard_from_flashlayout.sh ../flashlayout_IMAGE_NAME/..............

Then, flash as usual the obtained .raw file on a microSD:

$ sudo dd if=..............raw of=/dev/sdX bs=4M conv=fsync

To build a Qt5 cross-compile toolchain execute

$ bitbake meta-toolchain-qt5

Run Image:

Once you started your own baked image, execute these two commands before runing graphics applications:

$ psplash-drm-quit
$ export QT_QPA_EGLFS_ALWAYS_SET_MODE="1"
