I have resolved this issue by editting am335x-boneblack.dts and correcting the name os the uarts (from uart0, uart1, uart2, uart3, uart4 and uart5 to uart1, uart2, uart3, uart4, uart5 and uart6).
It's working now (needed to disable HDMI too). []'s Em quinta-feira, 12 de dezembro de 2013 12h32min41s UTC-2, Mike Bremford escreveu: > > That looks familiar.
