No UHD device found while running ALOE++ on VT CORNET

[Siddhartha]

Hi All,

I'm trying to run the OSLD waveform on a CORNET Node on the VT CORNET Testbed. When I try to run the osld_tx_usrp.app file, I get the following errors:

sidddhan@ubuntu:~/flexnets-aloe-c1dd2ac/app_dl$ sudo ../build/rtdal_lnx/runcf ./osld_tx_usrp.app ./config

Empty Device Address

sidddhan@ubuntu:~/flexnets-aloe-c1dd2ac/app_dl$ 

I believe this is probably because the file is not able to see the USRP device? I tried to see if the device was visible, but doing a "sudo ls -ltr /dev" is not showing a uhd or usrp device. I reinstalled the uhd driver for usrp2.0 as per the instructions on the Ettus website too.

Could anyone help with this error? How do I verify the UHD driver/device is installed?

Regards,

Siddhartha

Hi,

You can check that your usrp is working propertly using uhd/gnuradio tools, e.g. uhd_find_devices or uhd_fft.

If you are unable to see the usrp with these tools, check the uhd maillist.

Regards,
Ismael

Which Cornet node are you on? We're updating the first two floors, it's better to use nodes from the third and forth. Hope this helps.
