UDOO and rosserial-arduino: Unable to synch with device...

Hi all,

I'm working to a robot project with ROS and UDOO. I'm using ROS Hydro and Ubuntu 13.04.

I followed the tutorial on the Wiki ROS but Hello World example is not working for me.

When I run:

rosrun rosserial_python serial_node.py _port:=/dev/ttyUSB0

I can see following logs:

[INFO] [WallTime: 1065.166800] ROS Serial Python Node
[INFO] [WallTime: 1065.213625] Connecting to /dev/ttymxc3 at 57600 baud
[ERROR] [WallTime: 1082.335425] Unable to synch with devices: possible link problem or link software version such as hydro rosserial_python with groovy Arduino

I followed the tutorial step by step (the only further step needed was to use

 chmod 777 /dev/ttymxc3 i

in order to have permission to access the serial port).

I installed ROS Hydro from scratch and Groovy was not installed before on my UDOO.

I also make a test with a dummy Arduino sketch to send a string over Serial and checking the result with:

cat /dev/ttymxc3

And I was able to see the messages on my console. So I'm sure communication works...

Any idea?

Thanks Alessandro
