I tried 4.4.1-rt6, but it does not boot, I get absolutely no message on the debug port interface. I'm a complete newbie on Linux RT, so I may well have done something wrong, but the same kernel config without CONFIG_PREEMPT_RT runs fine. I'm a bit confused about what is needed for running 4.4.1-rt6 on this board: it seems some of your patches got merged, could you please clarify the situation? Are there some peripherals not supported (I mainly need ADC and PWM)?
