I have Navio2 with RPi3 for a few months now. It worked OK until yesterday, when RC stopped working.
I checked PPM input and see that signal from receiver is coming:
But Navio seems like doesn’t see it:
pi@navio:~ $ sudo cat /sys/kernel/rcio/status/alive 0
I did reflash SD card with fresh image 20160716, but it didn’t help.
