'earlycon' have to be passed to kernel command line via GRUB and NOT via device tree like this: chosen { bootargs = "earlycon"; Then just make sure you have following into chosen device tree node: chosen { stdout-path = "serial0"; -- You are receiving this mail because: You are on the CC list for the bug.
