Hi Mike - Thanks for the response. When I removed the init-clock recipe from our custom layer ( https://github.com/kratsg/meta-l1calo/blob/master/recipes-core/init/init-clock_1.0.0.bb) the board boots fine now. Any thoughts on why this recipe causes problems? It seemed to work fine a few months ago.
