Hi,
I upgraded the OS to Ubuntu 12.04, and now it does not have the error.
However, when I use build-gnuradio script, it failed to download the image
files:
Starting function firmware at: Mon Apr 22 11:00:23 JST 2013
Fetching and installing FPGA/Firmware images via wget...
ls: cannot access *.gz: No such file or directory
Failed to download any usable images file from:
http://files.ettus.com/uhd_releases/master_images
Is the server down?
Best,
Ting Wu

Try it just like this, you should see something like this output:

I am going to try and reproduce this on the same OS version. If anything its
probably just a rounding issue in the unit test. It would probably be OK to
continue using the build.

Thanks for bringing this up. The servers are up, so I must have
introduced a buglet into build-gnuradio.
Investigating now.

I just pushed a new version of build-gnuradio up to
http://www.sbrac.org/files/build-gnuradio
Should fix it.

Subject: [USRP-users] data packet with unknown SID [USRP B100]
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed
Hello,
I'm using gnuradio-3.6.4 with a USRP B100 right out of the box. I used
the `build-gnuradio` to make and install the package on Ubuntu 12.04 in
VMWare Player.
Running `uhd_fft` works. However, the second time it's launched I get a
`UHD Error: Got a data packet with unknown SID 196609` repeating. third
time uhd_fft launches but I receive no data. The only thing that fixes
it is power cycling.
Same thing happens when I run my own GRC application with a USRP device.
I'm having trouble finding anything in the last two years regarding this
issue.
Any thoughts?
Thank you kindly,
Joel

Hi,
I did some tests with gnuradio and USRP1 in a similar VM like yours, and it
did not work very well, lots of strange effects. With the real thing it just
works, means, a Linux (Kubuntu 12.04 in my case) directly installed on a
physical existing machine.

After checking the cable, and following the post installation instruction
for N series, now the GPS has been detected. But now when I run following
command
*uhd_usrp_source= uhd.usrp_source(device_addr="addr=192.168.10.2",
stream_args=uhd.stream_args(
cpu_format="fc32",
channels=range(1),
),
)
*
*print uhd_usrp_source.get_mboard_sensor("gps_time").to_int()*
I am getting the following error
return _uhd_swig.uhd_usrp_source_sptr_get_mboard_sensor(self, *args,
**kwargs)
RuntimeError: LookupError: Path not found in tree:

Subject: [USRP-users] about overflow on laptop
Message-ID:

Dear list,
Now I met a very strange overflow problem with my new laptop. My code works
fine on my old desktop but now I have got a new laptop. I always get overflow
when I connect to usrp N210. Even if I just test the benchmark with very low
bitrate (250khz, gmsk), I still met overflow.
I am quite sure it should not be because of the performance of CPU, because the
use of CPU is just around 50% (CPU is i7-3520M 2.9ghz*4). I have tried a lot
but still can not find out where is the problem.
The uhd I used is 003.005.000
Anyone has met the same problem? Any suggestions would be appreciate.
Best regards
Zan

Hi,
The problem is possibly with the lan card.
Is the lan card of your computer intel 82577 or intel 82579?
When I used computers with these two types of lan cards, I always saw
overflow problems.
Later when we buy new computers, we avoid these two types of lan cards and
we never see the problem again.
Best,
Ting Wu
