Hello Raul,

Could you please recompile the gnb in Debug mode and share the backtrace printed after the assertion gets triggered?

To do so pass this -DCMAKE_BUILD_TYPE=Debug to cmake before rebuilding the gnb.

sudo cmake ../ -DENABLE_EXPORT=ON -DENABLE_ZEROMQ=ON -DCMAKE_BUILD_TYPE=Debug

[faluco]

Yes, build the gnb and run it, then share the backtrace after the assertion message is printed

[raul-parada]

I got this now:

Lower PHY in executor blocking mode.

This message is printed when the gnb cannot connect to the core network. Please make sure you are running a core network and that the correct IP addresses are set. You can check these settings in the following documentation link: https://docs.srsran.com/projects/project/en/latest/tutorials/source/amariUE/source/index.html?highlight=zmq#id4

[raul-parada]

I have running 5GCore (open5gs), however, it is not clear the IPs I should configure and where

[faluco]

These settings can be configured in the .yaml configuration file of the gnb. Inside the configs directory of the project you can find sample configuration files and at the beginning you'll find these specific settings.

• addr should match the IP address of your AMF (where the gnb will try to connect)
• bind_addr should be your local connection to bind for the AMF connection

[raul-parada]

In the https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html says to use a given gnb.yaml file with a given configuration. Which IP rang should I use then? I would like to do the mentioned tutorial.

[faluco]

As it seems you are using open5gs in a docker the ip addresses should be the ones in the gnb config file. Please check the open5gs logs for any errors when the gnb tries to connect and that those ip addresses are accessible. Also, check this troubleshooting section: https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html#core-network-not-running

[ismagom]

Hi @raul-parada, do you have any update on the original issue?

[raul-parada]

Looks solved!
