Copter 3-4-rc4 on Navio2- strange brehaviour

Hi All
I run ArduCopter 3-4 rc4 on Navio2 i lunch it by typing following command :ArduCopter -A /dev/ttyAMA0 -C tcp: > /home/pu/starup.log
I connected micro minimoSD to UART port. But I get only NO INPUT DATA on screen.
When I connect to navio2 with MP throught TCP …data appears on minimOSD screen…
Is it correct ???
And One more question
How I can run ArduCopter to use UART port for minimOSD and USB port for telemetry ( with UART adapter of course)
ArduCopter -A /dev/ttyAMA0 -C /dev/ttyUSB0 ???
Thx in advance

Yes, because you specified that you want to wait on data (:wait flag).

Try ```ArduCopter-quad -A udp: -C /dev/ttyAMA0````

Seems about right.

You can also use -D or -F switches, but in case of latter you’ll need to update the SERIAL5_PROTOCOL to either MAVLINK or MAVLINK2 in your GCS.

Thx a lot
I will try
