uhd_usrp_probe not working with NI USRP-2952R over PCI

[radioninja]

Hi,

I installed NI USRP RIO PCI driver from http://files.ettus.com/manual/page_ni_rio_kernel.html. But I am not able to probe my USRP using uhd_usrp_probe/uhd_find_devices. I recompiled uhd and is facing the same issue. Please find the logs given below.

OS: Archlinux 3.17.1-1-ARCH
 

Some outuput logs

>> sudo /usr/local/bin/niusrprio_pcie start

Thanks in advance

radioninja,

1. Can you confirm that the daemon niusrpriorpc processor is running?

2. What version of NI-RIO do you have installed? (If you didn't install this manually/separately from the USRP RIO, then that's good enough.)

3. Are you able to modprobe niusrpriok on its own? The Ettus webpage you linked says "Currently, the latest supported kernel version is 3.14.x." I wonder if the 3.17 kernel has any breaking API changes from 3.14.

Thanks!

Brooksprumo,

1. Can you confirm that the daemon niusrpriorpc processor is running?

>>ps -au | grep niusrpriorpc
root 1082 0.0 0.0 27848 4832 pts/2 S 15:13 0:00 /usr/local/natinst/niusrp/bin/niusrpriorpc

2. What version of NI-RIO do you have installed? (If you didn't install this manually/separately from the USRP RIO, then that's good enough.)

niusrpriodistributioni-1.0.1f0. I installed it manually from the .gz from ettus site. Is this version good enough for NI USRP-2952R? I couldn't find any linux driver in NI website also.

3. Are you able to modprobe niusrpriok on its own? The Ettus webpage you linked says "Currently, the latest supported kernel version is 3.14.x." I wonder if the 3.17 kernel has any breaking API changes from 3.14.

Yes, modprobe works. I am not sure about any API changes. The module gets loaded without complaining.

Ok, cool. This is all good to hear. The version of the USRP RIO software you have (version 1.0.1f0) was built for UHD verion 3.7, so I'm gonna confirm that UHD version 3.8 should still work with USRP RIO verion 1.0.1f0. In the meantime, can you run `lsmod | grep -i n` and let me know what it says?

[radioninja]

>>lsmod | grep -i n
niusrpriok 386125 0
NiRioSrv 734204 0
nistreamk 131846 2 niusrpriok,NiRioSrv
nibds 51513 2 niusrpriok,NiRioSrv
nikal 71006 4 niusrpriok,nibds,NiRioSrv,nistreamk

[brooksprumo]

Well, everything looks good from your lsmod output. I also confirmed that UHD 3.8 is supposed to work with USRP RIO 1.0.1f0, so unfortunately I'm out of ideas for what to try next... I'm trying to get in touch with the Ettus people directly to see if they have any suggestions or if they've had success with the 3.17 kernel. I guess now that I think about it, if you can get an older kernel, I'd try that out.

Thanks brooksprumo. "usrp-users" mailing list is moderated I think. I am not able to post there for some reason. Anyways thanks for the ideas. I will get some SFP+ adapters and will switch Ethernet mode.
