Hello Richard,

Thank you for reaching out with your question. Let’s address the issues you’re encountering with your Yocto build for the Verdin AM62 module using the Crops Docker container.

  1. Missing Tarball Output:

    • The absence of the expected tarball in the deploy/images/[machine] directory suggests the build might not have completed successfully. Ensure that the build process finishes without critical errors.
    • Double-check that the IMAGE variable in your Docker run command is set correctly. For Torizon, it should typically be torizon-core-docker or a similar variant.
    • Verify your local.conf file in the Yocto build configuration to ensure the IMAGE_FSTYPES variable includes tar.bz2 or tar.gz if you expect a tarball output.

  2. Build Errors and Warnings:

    • The KeyError related to user ID mismatches often occurs when the Docker container’s user does not match the host system’s user. You can resolve this by running the Docker container with the --user flag to match the host’s user ID and group ID, like so: --user $(id -u):$(id -g).
    • The error getpwuid(): uid not found: 1000 indicates that UID 1000 does not exist in the container. Ensure the user inside the container has the same UID as your host user.
    • For the failed tasks, examine the detailed logs in the temp directory of the build output for more specific error messages, which can provide further insights.

  3. General Recommendations:

    • Ensure your Docker environment is set up with adequate resources (CPU, memory, and disk space) to handle the build process.
    • If your goal is to customize Torizon OS without deep involvement in Yocto, consider using the TorizonCore Builder tool, which simplifies many aspects of image customization and deployment.

By addressing these points, you should be able to resolve the issues with your Yocto build process. If you continue to experience problems, further investigation into the specific error logs and configurations may be necessary.
