[Paparazzi-devel] problem connecting GCS via serial to Tiny v/2.11

[Árni Þorvaldsson]

Hi all

I am trying to connect to the tiny via serial but I am getting blank GCS.

I am using
Airframe: funjet_example.xml
flight plan: basic.xml
Telemetry: default.xml

Uploading to the board works fine an then I launch
Session Flight address@hidden
get the error
Failure("Error opening modem serial device : fd < 0 (/dev/ttyUSB0)")

I get blank CGS and then plug in the serial to USB using PPZUAV FTDI Utility 
board V1.0
but nothing happens.

I ran sudo|dmesg and got

I have also tried to set the baudrate in airframe to 9600

 <!-- Communication -->
    <subsystem name="telemetry" type="transparent_usb"/>
    <configure name="MODEM_BAUD"    value="B9600"/>

Is there anything I am missing?
