[srslte-users] A question : when we use usrp b210 running

Tue Oct 2 18:51:35 UTC 2018

"O" - computer isn't consuming samples fast enough
"U" - computer isn’t supplying samples fast enough
"L" - Late, you sent samples with a time spec, but the time spec has passed by the time they got there

I assume you are using linux. Make sure your computer is in performance mode 

https://askubuntu.com/questions/604720/setting-to-high-performance

Make sure you are using USB 3.0 ports and make sure they are running at USB 3.0 speeds. Make sure your cables are spec'd for USB 3.0 as well.

Dear,

When we use usrp b210 running enb, error occurs.

When I run a simulation, I get a few/many "O" , "U" and "L" messages on the command line.
What dose that mean? And what should I do to make enb work normally？

Thanks!

Hi all,

I was trying to run srsUE on bladerf x40, however, I received the following warnings and errors:

Hey,

just copy+paste from your mail which already contains the answer:

"AGC commands for FPGA v0.7.3 are incompatible with this version of
libbladeRF. Please update to FPGA v0.8.0 or newer to use AGC."

Cheers
Andre
