title: ROS2 foxy on Yocto 3 (zeus)
body: <p>I have an image built using Yocto. The version is 3.0 (zeus) and unfortunately I can't change/upgrade it since that come from the board supplier. So I've cloned the zeus branch:</p>
  <p><code>git clone --single-branch --branch zeus https://github.com/ros/meta-ros.git</code></p>
  <p>and added the layer to bblayrs.conf:</p>
  <p><code> BBLAYERS += &quot;${BSPDIR}/sources/meta-ros/meta-ros2-foxy&quot;</code></p>
  <p>Unfortunately the build failed with error:</p>
  <blockquote>
  <p>ERROR: Layer ros2-foxy-layer is not compatible with the core layer
  which only supports these series: zeus</p>
  </blockquote>
  <p>What did I wrong and how to fix that?</p>
