LAYERSERIES_COMPAT_phosphor-layer <-- correct LAYERSERIES_COMPAT:phosphor-layer <-- incorrect. If you were a little too aggressive at making this change (like me) you can fix it with: $ git grep -l "LAYERSERIES_COMPAT:" meta-facebook | xargs sed -i 's/LAYERSERIES_COMPAT:/LAYERSERIES_COMPAT_/' $ git grep -l "BBFILE_PATTERN:" meta-facebook | xargs sed -i 's/BBFILE_PATTERN:/BBFILE_PATTERN_/' 2. local.conf.sample has changed slightly and CONF_VERSION needs to be incremented. The suggestion from upstream is to use your favorite diff-editor to compare the two such as: $ vimdiff ./poky/meta-poky/conf/local.conf.sample meta-facebook/meta-tiogapass/conf/local.conf.sample Except that we don't have this file updated until we do the subtree pull, so in the meantime you could compare against this version (use wget/curl): http://git.yoctoproject.org/cgit/cgit.cgi/poky/plain/meta-poky/conf/local.conf.sample 3. LAYERSERIES_COMPAT will need "honister" added since that is the next Yocto release after hardknott. Potential fixup: $ git grep -l "LAYERSERIES_COMPAT_" meta-facebook | xargs sed -i 's/hardknott"/hardknott honister"/' -- Patrick Williams
