Hi,

I notice that you are using Linux. Were you able to detect the USRP 2932 properly?

From this article, it is stated that USRP drivers do not have support for Linux.

Hi, Thanks for your attention! I have burned the uhd that compatible to Linux. And when I used gnu-radio, all things were right with nothing error. But got wrong when using srsLTE.

Not sure wheter srsLTE supports USRP-2932. It is not in the list of tested hardware.

Hi guozi,

 

As your screenshot, USRP-2932 uses N210 motherboard.

According to the GitHub(https://github.com/srsLTE/srsLTE), N210 is not included in tested USRP systems.

The hardware limitation is that the master clock of the N210 is fixed at 100 MHz, which is not a multiple of common LTE sample rates.

Hi guozi, I am having the same issue with N series device as well. Can you point it out to me the steps that you followed when running srsenb command.
