Hello

I need some help in troubleshooting pcie link card. I can see orange LED 
glowing in the card and even on giving the command lspci, I am not able to see 
the card in the list. Please help me with the troubleshooting.

[USRP-users] X310

2021-04-05 Thread Muhammed Mustaqim 
Hi,

Quick Question,

Can I run USRP X310 with a single UBX 160 MHz daughteboard, or do I have to
have 2 daughterboards in order to run X310.

Hi Snehasish,


chances are that if the board doesn't show up in lspci, there's not much you 
can debug;
your mainboard doesn't seem to play nice.

Try the following:


* Check dmesg for anything related to PCIe enumeration

* Check in your BIOS/UEFI setup whether it has some dialog to list connected 
PCIe devices

* Check whether using a different PCIe slot helps

* Check whether your mainboard's PCIe lane assignments can be changed. This is 
often the
case for gamer mainboards with 2011 to ca 2019 intel CPUs, but it's also the 
case on some
other platforms.


Best regards,

Marcus

[USRP-users] Re: Problem with interfacing Raspberry Pi 4 to USRP B210 with Python API

2021-04-05 Thread Clark (US), Kenneth C 
Brendan,



I am just using the ‘examples’ C/C++ builds.  I have not used the python 
modules.



I would think editing the CMake file would remove the need for the –D flag.



I have had very good luck running a B205 USB-3 on a RPi-4-8GB.  Only a couple 
of dependencies to install, which were documented on the Ettus UHD website.



I did create a RAM-Drive, since the 8 GByte RAM has room for that.  And I am 
able to reliably record above 20 Msps with the ‘wire format’ at 16-bit complex 
I&Q.  (No real reason to do 32-float, since the native samples are 16-bit I&Q 
in the FPGA on the B205, right?)



I use the ‘host examples’ in the latest 4.x version of UHD.  And they are 
pretty easy to modify.  I have adapted for things like using the 1-PPS, and 
doing times receive and transmit.



Ken

Thanks Ken.  As you suggested, I added -DCMAKE_EXE_LINKER_FLAGS="-latomic" to 
the CMake call.



The good news is that the UHD build & installation process completed 
successfully.



The bad news is that when I try to import the uhd module in Python3, I get the 
following error:



pi@raspberrypi:~ $ python3
Python 3.7.3 (default, Jan 22 2021, 20:04:44)
[GCC 8.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import uhd
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python3/dist-packages/uhd/__init__.py", line 10, in

from . import libpyuhd as lib
ImportError: /usr/local/lib/libuhd.so.4.0.0: undefined symbol: 
__atomic_fetch_add_8
>>>



Did you encounter this problem too?



I guess the next step is to hack the "CMakeLists.txt" files as per the link you 
sent me.  Just to clarify one point first:  If I modify the CMakeLists.txt 
files, do I still need to include -DCMAKE_EXE_LINKER_FLAGS="-latomic" in the 
CMake call?



Thanks,

Brendan.

   Hi Marcus,

   I have tried your suggestion, but unfortunately without success:

   Per your advice, I have edited the file "cmake.lwt" in the folder 
/usr/local/lib/python3.7/dist-packages/pybombs/templates to include the option 
"-DENABLE_PYTHON_API=ON" in the calls to cmake.  The modified commands are as 
follows:

   configure: cmake .. -DENABLE_PYTHON_API=ON 
-DCMAKE_BUILD_TYPE=$cmakebuildtype -DCMAKE_INSTALL_PREFIX=$prefix $config_opt 
-Wno-dev
   configure_static: cmake .. -DENABLE_PYTHON_API=ON 
-DCMAKE_BUILD_TYPE=$cmakebuildtype -DCMAKE_
