Getting the usrp and gnuradio going... Problems

GNU Radio
1

Hi all

SuSE 10.1, Subversion as of a day or two ago, sdcc built from source.
USRP box arrived here two days ago…

Configure/build of gnuradio worked fine after I grabbed all the right
packages. The SuSE instruction kind of has the wrong python path
specified but that was easy to fix. I have done the udev/hotplug mod but
am running as root whilst I work the problem.

Can turn LED on and off with usper. The USB info in /var/log/messages
looks fine.

I have plugged in a basic and 0-50MHz RX in RX A. In a fit of problem
solving I additionally plugged a basic RX into RX B.

When I try to run;

Type “cd gnuradio-examples/python/usrp” and hit Enter. Type “python
test_counting.py” and hit Enter.

The LED rate slows down and maybe 10 seconds later I get a error dump;

usrp_open_interface:usb_claim_interface: failed interface 2
could not claim interface 2: No such file or directory
usrp_basic_rx: can’t open rx interface
Traceback (most recent call last):
File “test_counting.py”, line 53, in ?
main ()
File “test_counting.py”, line 46, in main
fg = build_graph ()
File “test_counting.py”, line 36, in build_graph
usrp_rx = usrp.source_s (0, rx_decim, 1, 0x32103210,
usrp.FPGA_MODE_COUNTING)
File “/usr/local/lib/python2.4/site-packages/gnuradio/usrp.py”, line
266, in init
fpga_filename, firmware_filename)
File “/usr/local/lib/python2.4/site-packages/gnuradio/usrp1.py”, line
1547, in source_s
return _usrp1.source_s(*args)
RuntimeError: std::runtime_error

At this stage the LED rate is still slow. If I resubmit the command the
error dump is immediate.

As with all error messages one must look at the first one. One assumes
“Failed Interface” means it cant talk to the RX but I’d like some
thoughts on this… Is it USB related? I saw quite a few postings on that
topic but could sort anything specific. USB related modules loaded are;

usblp 12544 0
usb_storage 69952 1
scsi_mod 121992 3 sg,sd_mod,usb_storage
usbcore 108804 4 usblp,usb_storage,ohci_hcd
ide_core 115900 4 usb_storage,ide_cd,sis5513,ide_disk

The printer is one of those HP All-In-One things with a front panel USB
port/flash card holder. I have yet tried to run the USRP without the
printer attached.

Maybe there needs to be a /dev entry somewhere (Thinking “No such file
or directory”)

I also saw a post about checking the firmware existed in
/usr/local/share/usrp/rev4 and rev2. The filename the post had and what
I have are different! (The post was back in 2005 though)

Any thoughts or guidance appreciated

This happens when either your machine doesn’t have a USB2 controller
(EHCI) or when the EHCI module isn’t loaded.

On one of my SuSE 10.1 machines I get this:

[eb@cyan mail]$ lsmod | grep -E ‘(usb|ehci)’
usbhid 44640 0
ehci_hcd 31880 0
