[srslte-users] srsue crashing on found cell

[Yaroslav de la Peña Smirnov]

Hello,

I've been trying to connect srsue to an Amarisoft eNB, but each time it
finds the cell it crashes. I am using a USRP X310 with UHD drivers 3.15
compiled from source.

This is what I get from stdout:

And this is what I get from the srsLTE.backtrace.crash file:

Thank you very much for your help.

Kind regards,
