Does ardusub-3.4 support telem1/2 communication with pixhawk?

hello,
I am new guys in bluerov and i am trying using raspberry pi3 communicate with pixhawk using telem1/2 not usb interface, i have download ardusub-3.4 firmware to pixhawk and buring p3 with Ardusub-Raspbian Image(2017-01-12), i am sure my hardware connection is correct, but when i try to communicate each using following commnand:

#mavproxy.py --master=/dev/ttyAMA0,57600
–source-system=200
–cmd=“set heartbeat 0”
–out udpin:localhost:9000
–out udpbcast:192.168.2.255:14550

just come out follow messages:

Connect /dev/ttyAMA0,57600 source_system=200
Failed to load module: No module named terrain. Use ‘set moddebug 3’ in the MAVProxy console to enable traceback
Failed to load module: No module named adsb. Use ‘set moddebug 3’ in the MAVProxy console to enable traceback
Log Directory:
Telemetry log: mav.tlog
MAV>

i am sure i have changed pixhawk serial1 baudrate param to 57600 using qgroundcontrol also, i have tried many times, the results are same, i am wondering pi image or ardusub-3.4 support telem1/2 communiate with mavproxy, could you please give me some suggestions or ideas about this issues.
thanks a lot

It is absolutely possible to communicate over the telem ports. Make sure you are using the right serial interface (/dev/ttyxxx) for your Raspberry Pi model, and that you have configured the Raspberry Pi UART correctly. Please see the releated posts here and here.
