Hi.
I'm trying to transmit IQ samples from OAI through USRP x410 but I'm getting the following error: "Segmentation fault".
The command that I'm using for OAI is the following one: sudo ./nr-softmodem -O ../../../ci-scripts/conf_files/OAI_gNB.conf --sa
I've also checked the frequency configured for my usrp through the command below and it is inside the range of the one defined in OAI.
uhd_usrp_probe --args="addr=ip_of_my_x410"
I think the issue comes from the version of uhd that I'm currently working (uhd 4.1.5) but before changing anything I want to make sure that the error is not coming from something else.
I decided to put this question on this post because I think is a problem of UHD and MPM not of OAI because I know the code works fine for x300 series.
Last but not least, I attach the .conf files in this question.
Thank you in advance.

Hi TeamPHY,
from the provided image I cannot see where the error should originate from.
Is there a way to enable logging in "nr-softmodem", for example through a command line parameter, or as option in the .conf file?
If not: Maybe you can attach a debugger to the nr-softmodem to see where the segfault occurs (see c++ - Determine the line of code that causes a segmentation fault? - Stack Overflow)
Best regards
