This working group aims to put together end-to-end system reference material showcasing all the different aspects of OpenAMP, on multiple vendor platforms.
- To sign up for the mailing list and to see the archives, visit this page
- Meetings: Small group who is working on the project is meeting meeting weekly on Wednesday during Aug-Oct 2021 & then will decide on frequency.
- Reach out on the Mailing list if you need info about this.

WIP documentation folder on Google Drive (Note: Google doc access is currently restricted to working group members. Will publish documents once they are sufficiently ready)
Intruction to install the yocto environement, build and load an image, run the echo exemple is available here: https://github.com/arnopo/oe-manifest/blob/OpenAMP/README.md
For more information and help on the stm32mp15 platform and environment, please refer to stm32mpu wiki.
WIP document (Note: Google doc access is currently restricted to working group members. To publish once it is sufficiently ready)
Based on:
- a fork of the yocto [meta-st-stm32mp-oss](https://github.com/STMicroelectronics/meta-st-stm32mp-oss) environment, designed to update and test upstream code on STM32MP boards.
- a fork of the yocto [meta-zephyr](https://git.yoctoproject.org/meta-zephyr/)
