As preparation for completing the work to upgrade ZMK to Zephyr 3.0, users with user config repositories who wish to avoid future build failures with their GitHub Actions workflows can take steps to adjust their repositories now.
GitHub Actions needs to use our latest Docker image to ensure continued compatibility with the ZMK codebase on Zephyr 3.0 (and beyond). You should:
- Open
.github/workflows/build.ymlin your editor/IDE - Change
zmkfirmware/zmk-build-arm:2.5tozmkfirmware/zmk-build-arm:stablewherever it is found
Once the changes are committed and pushed, the build will run as expected.
A future blog post will outline the complete Zephyr 3.0 changes once that work is finalized.
If you created your user config repository a while ago, you may find that your build.yml file instead references
a zephyr-west-action-arm custom GitHub Action instead. In this case, the upgrade is not as direct. We suggest that
instead you re-create your config repository to get an updated setup using the new automation
approach.
