1. Overview

This page describes how to build the Torizon OS for the STM32MPx development boards, including:

...

1. meta-st-stm32mp - BSP Layer for the STM32MP targets developed by STMicroelectonics for the OpenSTLinux project: https://wiki.st.com/stm32mpu/wiki/Category:Yocto-based_OpenSTLinux_embedded_software

2. meta-emcraft-torizon-st - adaptation of the STM32MP BSP for Torizon OS developed by Emcraft.

...

1. Set up the default git user and e-mail:

   Code Block
   $ git config --global user.email "you@example.com" $ git config --global user.name "Your Name"

2. Install the repo utility to the development host:

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

3. Create a working directory for the Yocto build, go into that directory:

   Code Block
   $ cd ~ $ mkdir ~/yocto-workdir $ cd ~/yocto-workdir

4. Initialize the Torizon OS reposiotiy:

   Code Block
   $ repo init -u git://git.toradex.com/toradex-manifest.git -b kirkstone-6.x.y -m torizoncore/default.xml

5. Sync the repositories:

   Code Block
   $ repo sync

6. Download the ST32MP BSP layer:

   Code Block
   $ git -C layers clone -b mickledore https://github.com/STMicroelectronics/meta-st-stm32mp

7. Download the ST32MP Torizon compatibility layer:

   Code Block
   $ git -C layers clone -b kirkstone git@github.com:EmcraftSystems/meta-emcraft-torizon-st.git

8. Replace the setup environment link and the Docker build link:

   Code Block
   $ ln -sf layers/meta-emcraft-torizon-st/scripts/setup-environment setup-environment
