Old versions

Building own image

VisionSOM-STM32MP1 module is supported by Yocto meta-layer available on SoMLabs github:

https://github.com/SoMLabs/openst-meta-somlabs

The described layer shall be used with the OpenSTLinux Distribution Package provided by the STMicroelectronics:

https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package

It provides the support for VisionSOM-STM32MP1 module and VisionCB-STD-STM32MP1 board and is intended for build with the st-image-weston system image.

Host PC requirements

This tutorial was tested on the Xubuntu 18.04 LTS system. The distribution and SDK building requires significant amount of memory, disk space and time. The following hardware configuration was used for compilation:

  • Intel Core i7-4510U
  • 8GB RAM
  • 256GB SSD Disk (30GB required for system build and another 30GB for SDK)

The OpenSTLinux compilation time takes about 8 hours. The SDK building requires another 8 hours when building with the already compiled system.

The PC requirements suggested by the STMicroelectronics may be found here:

https://wiki.st.com/stm32mpu/wiki/PC_prerequisites

The host system needs also the following packages to be installed:

sudo apt-get update
sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping
sudo apt-get install libsdl1.2-dev xterm
sudo apt-get install make xsltproc docbook-utils fop dblatex xmlto
sudo apt-get install python-git
sudo apt-get install repo

Obtaining the Yocto recipes

The following steps are the summary of the image building description that can be found on the ST wiki pages with the additional SoMLabs meta-layer.

First let's clone all of the repositories containing the required packages and system distribution:

cd <working directory path>/Distribution-Package
mkdir openstlinux-5.4-dunfell-mp1-20-11-12
cd openstlinux-5.4-dunfell-mp1-20-11-12
repo init -u https://github.com/STMicroelectronics/oe-manifest.git -b refs/tags/openstlinux-5.4-dunfell-mp1-20-11-12
repo sync
cd layers/meta-st
git clone -b dunfell https://github.com/SoMLabs/openst-meta-somlabs.git meta-somlabs
cd ../../

The last git clone instruction downloads the meta layer with VisionSOM-STM32MP1 module support.

Bulding the system image

The following commands generate the OpenSTLinux weston image that can be run on VisionSOM-STM32MP1 module and VisionCB-STD-STM32MP1 board:

DISTRO=openstlinux-weston MACHINE=<MACHINE_NAME> source layers/meta-st/scripts/envsetup.sh
bitbake st-image-weston

The following VisionSOM machines are available:

  • stm32mp157a-visionsom-rgb-emmc-mx Module with eMMC memory and RGB display connected
  • stm32mp157a-visionsom-rgb-sd-mx Module with SD card and RGB display connected
  • stm32mp157a-visionsom-dsi-emmc-mx Module with eMMC memory and DSI display connected
  • stm32mp157a-visionsom-dsi-sd-mx Module with SD card and DSI display connected

The compiled image files are located in the directory:

openstlinux-5.4-dunfell-mp1-20-06-24/build-openstlinuxweston-<MACHINE_NAME>/tmp-glibc/deploy/images/<MACHINE_NAME>

In order to prepare the SD card system file the following command is required:

cd tmp-glibc/deploy/images/<MACHINE_NAME>
./create_sdcard_from_flashlayout.sh ../flashlayout_st-image-weston/trusted/FlashLayout_sdcard_<MACHINE_NAME>-trusted.tsv

Building the SDK

In order to build the cross-compiler and required libraries for software development on the host machine we need to build the SDK. After building the system image as described in the previous chapters we can simply call another bitbake command:

bitbake st-image-weston -c populate_sdk

It will create the SDK installer st-image-weston-openstlinux-weston-stm32mp157a-visionsom-mx-x86_64-toolchain-2.6-snapshot.sh or st-image-weston-openstlinux-weston-stm32mp157a-visionsom-dsi-mx-x86_64-toolchain-2.6-snapshot.sh that is located in the tmp-glibc/deploy/sdk directory. The installation script should be run on the host machine to install the development toolchain.

Installing images

The following articles explain the image installation on the VisionSOM-STM32MP1 modules:
