Hello Michael,<br /><br />As i was preparing my patch v3, i found an issue with the LAYERSERIES_COMPAT Variable. bitbake and OE seems to be maintained separately but they are linked.<br />so for this hello world example should not include an OE release in bblayers.conf but :<br />if LAYERSERIES_COMPAT is not set it produces a warning, and if a default value is set but OE is not included, the build fails with&nbsp;<br />No core layer found to work with layer '%s'. Missing entry in bblayers.conf<br />this change was introduced in&nbsp;5815a7258ebb8a989e0c6f5798853559d9413f02 to fix&nbsp;<a href="https://bugzilla.yoctoproject.org/show_bug.cgi?id=14340" target="_blank" rel="noopener">https://bugzilla.yoctoproject.org/show_bug.cgi?id=14340</a><br />I would suggest, keeping the warning for now.<br /><br />Best regards,<br />Fawzi.
