Hi,

I'm working at the Beagle-ROS project (integration of the beaglebone and ROS through Angstrom and the meta-ros project). For now i have a minimal roscore running in the bone so i tried to check if the nodes that the core starts were correct.

I launched a rosnode list from the beaglebone but it doesn't return anything (since it returns without error i guess it can connect to the roscore).

So this means that the nodes are not even visible locally (in the same computer).
