Your guess is probably as good as ours without more info from the segmentation fault :)  Enable core dumps and usb GDB to see where you crashed.

Hi all,
I'm a BBN 802.11 & USRP2 beginner student. When I try to run the BBN 802.11b python script bbn_80211b_tx.py I receive this message:

address@hidden:~/bbn_80211/usrp2_version/gr-bbn/src/examples$ ./bbn_80211b_tx.py

segmentation fault

Exploring the code from bbn_80211b_tx.py, the example works fine until it has to start the flow graph. Do you know what could be happening?
