Error running BBN 802.11b example: segmentation fault

GNU Radio

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:

uwicore@uwicore-desktop:~/bbn_80211/usrp2_version/gr-bbn/src/examples$
./bbn_80211b_tx.py

gr_fir_ccf: using SSE
Network interface: eth0
USRP2 address: xx:xx:xx:xx:xx:xx (USRP2 MAC)
Using TX d’board id 0x0060
Tx baseband frequency: 2.4G
Tx DUC frequency: 0
Tx residual frequency: 0
Tx interpolation rate: 4

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?

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