How to add a meta layer to manage modifications

Hello,
I want to create a custom layer to share modifications with other users to align with the same environment.

Hi Kyle,

If you’d like to create a custom layer based on IOT Yocto, you can follow these steps (assuming you’ve already downloaded the IOT Yocto codebase):

  1. Create the custom layer:
    Run

    bitbake-layers create-layer $PROJ_ROOT/src/meta-custom

    Make sure you’ve configured the build environment as described in the developer guide before running the command.

  2. Configure the layer:
    Edit meta-custom/conf/layer.conf to adjust the settings as needed.

  3. Add recipes:
    Add any required .bb or .bbappend files to your new layer.

  4. Add the layer to your build:
    Run

    bitbake-layers add-layer $PROJ_ROOT/src/meta-custom

    This will add your custom layer to bblayers.conf in your build environment.

  5. (Optional) Verify the layer:
    Run

    bitbake-layers show-layers

    to confirm that your layer has been added successfully.

  6. Build your image:
    Run

    bitbake <image name>

    to test your changes.

If you’re satisfied with the result, you can simply compress the meta-custom folder and share the tarball with your users for quick, short-term distribution.

For long-term maintenance, it’s recommended to manage your own manifest to track changes to your custom layer.

Hello @Kyle,

How is everything going? Welcome to the Forums!

We have been working on a wiki to provide instructions on How To Create A Custom Meta-Layer For MediaTek Genio 510. The steps provided by @ramax.lo work as well, they are a bit of an automated way of creating the meta-layer. However, if you want to have a deeper understanding on how to do it manually and have more control over what your meta-layer has, we would recommend you to take a look at our Wiki.

Hope that helps.
Please do not hesitate to reach out if you require any further support, we would love to help.
