[SOLVED] Navio2: RC input doesn't work anymore


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

I did reflash SD card with fresh image 20160716, but it didn’t help.
Any ideas?

Is board screwed down properly? This might be a connection issue.

It is, but it feels loose when I connect it with RPi. I’ll check if I can make it more stiff.

Thanks for your reply.

It did work. Thanks a lot!!
