Subject: [USRP-users] Ver 3.7 stable?
Message-ID: <[email protected]>
Content-Type: text/plain; charset=ISO-2022-JP
Dear experts,
<I send this question to both GNU radio and USRP mailing lists. I do not
know which is better place for this discussion.>
(1) Introduction
I am Mamoru Yamamoto from Kyoto Univ.
Some may know that I am doing satellite-beacon experiment
by using USRP1 + GNU Radio. We call the receiver as
GRBR (GNU Radio Beacon Receiver).
http://www.rish.kyoto-u.ac.jp/digitalbeacon/
Sorry this web site is very old. Now I am using
USRP1 + uhd + GNU Radio from python script
Also I am using Ubuntu 12.04LTS.
My application is a very simple dual-channel receiver
recording IQ time-series on two files.
The system is VERY stable and useful. I like it very much.
(2) Current situation
Now I try to move to Ver 3.7.
(I installed the software by "build-gnuradio script".)
Necessary small changes for me were
-- "optfir.low_pass" location change
-- "freq_xlating_fir_filter_ccf" location change & centerfrequency
setting from negative to positive
-- "file_sink" location change
(3) Questions
These changes were done. I now start running the system,
but have problems. I have 2 questions.
Q1: I run the modified code with Ubuntu-32bit 12.04LTS. My code worked
for several times, but after that, it created only "0-byte" files
(=immediate stop), and then no files were created. I checked the uhd
status, and found that "uhd_find_devices" was successful while
"uhd_usrp_probe" failed (see below). I now connect USRP1 to USB3 port.
Is this wrong?
Q2: I also tried to use the same V3.7 code with Ubuntu-64bit 12.04LTS.
But output file from my code is always 0-bytes (=immediate stop).
Please tell me if 64bit OS is useless.
=== Check after the problem (Q1) ===

Thanks for your help and suggestions.

Many USB-3.0 controller and USB-2.0 device combinations don't work very
well-the USB-2.0 "downshifting" doesn't happen correctly.
Try your USRP1 on a USB-2.0 port instead.

Subject: [USRP-users] Inquiries on Ettus USRP E110 Hardware Driver?
Message-ID: <[email protected]>
Content-Type: text/plain; charset="windows-1256"
Hi,
I have encountered issue with of finding suitable driver of this device (Ettus
USRP E110).
Device: Ettus Research USRP E110 S/N No: E9R 12X6E2Daugtherboards: SBXSoftware:
Visual Studio 2010 C++Installed Software Dependencies: 1) CMake 2.6
2) Boost 1.55
3) LibUSB
4) Python 2.6
5) Cheetah 2.0Installed Driver: 1) UHD Driver version 003.007.001(Stable)
Report Issue: 1) Driver not detected in system device manager (Refer to
Attachment Picture No Driver.jpg)
2) Inappropriate driver(Refer to Attachment Picture
Driver From Ettus.jpg)
- Driver Link Source:
http://files.ettus.com/binaries/misc/erllc_uhd_winusb_driver.zip
- Supported Device in the zip package doesn't
include E110
Summary: What I was trying to do is just to run a simple example software that
come from the UHD folder after the driver installation(e.g. tx_waveforms.exe).
However, it won't run because my computer can't detect the USRP device. I
connect the USB console to my PC and run uhd_find_devices.exe file which show
that my PC does not detect the device.
Could you kindly send me a tutorials for using this device?
Thank you
RegardsSoon Chun Mein

Hi Chun,
The E110 series is an embedded platform and not accessible
from your computer via the UHD driver. You will need to use the CONSOLE
connection with a USB cable to access the embedded Linux platform. You copy
your GNU/Radio applications from your computer and run it on the E110.
Kind Regards,
Matthew
