solve ?
To: Gnuradio Mailing List<address@hidden>

Content-Type: text/plain; charset="iso-8859-1"
i've got a strange audio overrun (aOaOaO) problem. My scheme is the
following :
audio_source ----> FFT_graphical sink
*signal = audio.source(32000,'plughw:0,0', True)
fft = fftsink2.fft_sink_f(panel,title="Spettro Segnale Vocale",
sample_rate=64e3,y_per_div=20,ref_level=-70)
self.connect(signal,fft)*
it happens to get in random way these cases :
case 1 : i get it fully working with no errors in the terminal
case 2 : it works displaying the FFT with the terminal showing
repeatedly the "aO" error
case 3 : it shows the blank display of the FFT with the terminal
showing repeatedly the "aO" error
i edited in my home the *config.con*f file in *~./gnuradio* in this way
to override the settings:
*[DEFAULT]
verbose = False
[audio]
audio_module = audio_alsa
# specify which audio module to load, or use "auto" to have the system
# select one. Valid choices depend on your OS and which modules
# you've installed, but typically include: auto, audio_alsa,
# audio_oss, audio_portaudio, audio_jack, audio_osx, audio_windows
[audio_alsa]
default_input_device = plughw:0,0
default_output_device = plughw:0,0
period_time = 0.010 # in seconds
nperiods = 4 # total buffering =
period_time * nperiods
verbose = false
*
i'm using ubuntu 9.04 with the last unstable deb version dated
10.22.2009. If i enter the terminal and digit "*/asoundconf
set-default-card SB/*" (SB is my first listed audio card) and reboot it
seems to adjust by itself so i just decided to put it in the start
commands of the OS. The strange thing is that my laptop is a dual-core
laptop and i read that a fast computer could usually help to solve this
overrun problem (my previous laptop was not a good one :D). Did i maybe
need an update of the alsa drivers ? I hope you can help me....
thx in advance, Arturo

I am attempting to build gnuradio under cygwin and everything seems to go fine,
with the exception of the documentation for the usrp. unfortunately this shuts
down the make so that it never completes. Any guidance as to what I might be
missing or file changes that would enable this to complete the make process
would be appreciated.
Thanks,

This is a known problem with xmlto on Cygwin (see
http://gnuradio.org/trac/wiki/WindowsTips). The solution is to remove or
disable xmlto, or modify the Makefile so to bypass the building of the
documentation.

Subject: [Discuss-gnuradio] usrp2(s) won't flash LEDs
To: address@hidden
Message-ID:
<address@hidden>
Content-Type: text/plain; charset=ISO-8859-1
We received 4 new USRP2s this week with 2GB SD cards labelled
20091209. None of the USRP2s boot up, i.e. "flash the LEDs" with
these SD cards. I tried one of these cards in an older USRP2 and it
didn't work there either, but using an older 1GB SD card (not sure
what revision of FPGA or firmware) in one of the new USRP2s does (at
least) flash the LEDs.
I've tried reburning a new 2GB SD card with u2_flash_tool with various
revisions of txrx.bin and u2_rev2.bin without success. I've never
done this before so it's likely there is something wrong with my
procedure but I'm running out of things to try.
I am wondering if there is something about the 2GB SD cards that
shipped with the USRP2s as well as the one I bought (none of them are
HCSD of course but the one I bought yesterday is a Lexar Platinum II
60x).
I assume the LEDs should flash. Needless to say, find_usrps doesn't
see any USRP2s when I run it.

Hello All.
I finally had the opportunity to upgrade to the USRP2.0. I received it
in the mail yesterday, and I am playing around with it right now. I
hate to ask the noob question here, but for the life of me, I cannot
get it running.
Problem Description: When powering the USRP2.0 (with the SD card in
place), none of the LEDs [A-F] light up. There is power, the rear fan
turns, and the onboard D201 LED is illuminated.
I tried reloading the SD card a couple of times with different
versions of both the S/W and FPGA bin files.
address@hidden firmware]# ./u2_flash_tool --dev=/dev/sdd -t s/w txrx.bin -w
address@hidden firmware]# ./u2_flash_tool --dev=/dev/sdd -t fpga u2_rev3.bin -w
...
address@hidden firmware]#./u2_flash_tool --dev=/dev/sdd -t s/w
txrx_edk10.1_r10766.bin -w
address@hidden firmware]# ./u2_flash_tool --dev=/dev/sdd -t fpga
u2_rev3_ise10.1sp3_r10766.bin -w
...
When those failed produce any activity, I also tried a new SD card
which ended with the same results. I cannot see it making a
difference, but I am running Fedora 12 with the latest trunk code. I
have tried compiling my own bins as well as downloading the ones from:
http://gnuradio.org/releases/usrp2-bin/trunk/
Does anyone have any suggestions?
Thanks everyone
Jeff
