Hi,
* I've installed the latest and greatest gnuradio from git, everything
compiled fine.
* I have a pre-500 USRP1, and fixed the wiring of the clock to the four
daughterboard sockets.
* I've been running gnuradio on this hardware ~2 weeks ago successfully.
Now, when I try to run anything that connects to the USRP, it just
"hangs". It downloads the firmware (blinking gets slower), it identifies
my two WBX boards correctly, but:
---8<---
$ /opt/gnuradio/HEAD/share/gnuradio/examples/usrp/usrp_benchmark_usb.py
Testing 2MB/sec...
---8<---
...and that's where it ends. It just hangs there.
If I try usrp_oscope.py on a local radio station, I see *nothing*.
I also tried usrp_wfm_rcv_nogui.py:
$ usrp_wfm_rcv_nogui.py -f 100.6e6 -O plughw:0,0 -g 30
When I strace the process, I only see
select(0, NULL, NULL, NULL, {0, 2000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 4000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 8000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 16000}) = 0 (Timeout)
Any hints?
