Indeed, I've change supposed invalid addr 47:55:47:55:47:55:aa to 12:43:56:78:90:aa and it worked. So here I come and apolozige in advance if somebody already answered theses, I haven't found anything relevant in archives : How to determin if a EMAC is valid/legal ? Why u-boot doesn't implement such a validiy test -at least when debugging is defined- in order to defeat that strange developper reflex, looking for _the_ inexisting bug ?
