Thank you! > I haven't tried that patch on v4.1, so I am not aware of all the dependencies you may be missing. I have tried only on v4.2-rc* and it works fine to me. Other option would be to have "earlycon" in cmdline but remove baud in stdout-path in Juno DT and see if it provides any log as where it's getting hung during the boot. But I repeat that v4.1 with defconfig and DT compiled from source just works fine unless you are missing something in the firmware including DT. Hope that helps. Regards, Sudeep.
